Outstanding service as always. Would highly recommend. Thank you very much Andrew for your help.

Kudos to Bob and Levi! They found and repaired two propane leaks. They were courteous, friendly, efficient, and persistent. Thank you for your excellent service!

Excellent service with very knowledgeable professionals.

Paul was great! He was upfront about our system needs and condition. He worked to resolve our issue and offered suggestions along the way. He offered a service plan, but did not pressure us into making the purchase. He was professional and precise in his work and I felt comfortable having him in our home and working on our system. Cosby is great and so is Paul. Thank you!

Levi Steele came out to my house for an annual inspection and service of our furnace and air conditioning. I was impressed with his competence and thoroughness. I appreciated his honesty and hard work. He answered all of my questions and was very polite.

Cosby team of Zack, Lee, and Victor attention to detail made our HVAC installation a smooth and worry-free experience.

John was fast and efficient and very kind.

Carl is professional, friendly and extremely helpful.

Great service for 12 years and counting. Levi Steele was the serviceman today. Knowledgeable , professional and very personable

Mike and Sawyer were very professional and could not have been nicer or more helpful and cleaned up the work area and asked if there was anything else they could do or explain.

Carl does an excellent job.

Great service. Friendly and knowledgeable technician.

Thank you to Cosby for replacing my compressor! I want to say Joe and John were very professional and helpful. They showed up prepared and ready to go. I was also impressed with their knowledge which made me feel my system was in great care. I can confidently say if I have any future HVAC issues Cosby will be my first call.

I almost hesitate to post a negative review with the mass of positive reviews we've read and heard from friends about this company. It seems our experience is probably an outlier, but one I would have wanted to know before contacting them. First, we used the online contact form to make an appointment for our air conditioning, which hasn't been working well. They called promptly and made an appointment. However, I got both an email and a text message the next day saying that our appointment had been cancelled. When they called later to see if we could take an earlier appointment time, I mentioned that I'd received that email and text and the woman on the phone seemed baffled, since our appointment was still set. Second, when our tech arrived for the diagnostic appointment, we were underwhelmed with his knowledge. Perhaps he was having an off day, but he seemed exceptionally confused about why we would have multiple sensors in the house if the air was not split into compartments. We purchased the extra sensors to make sure the house was heating or cooling to appropriate temperatures, based primarily on the temperature in our kids' rooms. Otherwise, the system would heat and cool to the temperature of our thermostat sensor, which is in the living room. Third, he measured the cool air coming out of the vents and told us it was cooling within the range it should be. He reiterated that it was functioning at a level they would be looking for, but still recommended that the entire system be replaced. While we know the system is old and underperforming, he couldn't give a solid justification for why we would need a new system when his tests showed it was, by his measurements, working fine. Finally, I was put off by the follow up email I received 13 days after the diagnostic visit. While I fully understand the need for follow up, the phrasing felt passive aggressive, referring to service I received "back in May." Although we had expressed strong interest in having coolant added to our system first to make sure it wasn't a problem caused by a slow leak, the only follow up mention was about replacing our entire system. While most of these things are small (the "cancellation," confusion about the sensors, and follow up email), they add up to an unsatisfactory experience, especially when combined with the feedback about how our system was cooling to spec (but that we should still buy a new one, for thousands of dollars, anyway).

5 stars are not enough to praise their work. john came to our house in marengo. he went far above my expectations. he performed a thorough inspection of our hvac unit. his inspection found no problems. he did rewire/install (updating to the new nec electrical code) a new on/off switch to the furnace. complete with 2 new junction boxes, flex conduit, etc.

I had such good and timely service. I will certainly use use your service in the future. Thank you so much. Yolanda

Very happy with my experience with Cosby, and would definitely recommend them to anyone. Our service tech Paul was friendly, communicated well and did a great job.

timely, informed, polite, effective

Levi was very considerate and conscientious of my home. He did a thorough check of my system. He informed me of the status and updated me during his visit. Cosby provides knowledgable and courteous technicians.

Levi Steele was very professional and answered all my questions, he was courteous.

Levi Steele did a great job today . He serviced our furnace and air conditioner. He was punctual, polite, and not pushy.

John Robertson came and provided maintenance on our air conditioning unit. We just wanted our system checked and we wanted a maintenance agreement for the next year to make sure things were checked out by professionals. John was extremely professional. He was very thorough. He even went above and beyond by replacing our batteries in our thermostat. John checked out and wrote down all the measurements of the Freon and all parts/filters. Our previous air and furnace company, Dor Mar( which we used for 30 years) told us that last year we needed $500 worth of Freon. John Robertson with Cosby said we did not need any Freon. He said if we had added some last year it would have been overfilled and possible caused damage. It is hard to find honest workers/companies. We are very pleased to now call ourselves Cosby customers. Less

Our system was recently serviced for the summer. Our Technician this time was Levi Steele. A very nice and polite young man. He was very thorough and answered my questions with detail. I’ve always been satisfied with Cosby and look forward to seeing Levi Steele again👍

For one, Levi was friendly and very through. He found several factory cause issues and his attention to detail has my A/C working with out any rattling. The plus was that he had a extra filter on hand with him. Saving me time of having to do it myself. Very good 👍 service, thank you Cosby and Levi Steele.

I received excellent service from Levi Steele. He is friendly, informed and very knowledgeable. I highly recommend Levi at Cosby Heating and Cooling.

I highly recommend Carl Crozier of Crosby heating and cooling. He was very pleasant, informative, and fast.

Great employee

Great service! They were able to get an accurate idea of what the issue was with my furnace over the phone and quickly got me scheduled in. Paul came out, replaced the parts, and was very fast. Left the place clean when finished as well.

We had maintenance service on our air conditioner. Levi was very knowledgeable and very nice. He checked everything thoroughly and didn't leave until he made sure we didn't have any questions or concerns.

John was very professional and did a very thorough job.

The service technician went the extra mile to help me out on the weekend. I appreciate his prompt and courteous service.

Very nice young man. Very knowledgeable about his job and everything that needed done. Made sure he answered all of our questions before he left. Told Levi we would love for him to come back this fall for our furnace maintenance check.

Cosby heating and cooling have been absolutely wonderful! We had them come out in fall of 2023 after our system stopped working and they explained everything so well! We had maintenance done and a filter replacement today 3/29/24 - Levi did such a fantastic job explaining everything and taking care of us! Would absolutely recommend using them!

Joe has kept my family warm in the winter and cool in the summer for over 15 years. From new installs to keeping our old furnace running, he and his team have been wonderful to work with. I highly recommend them.

Excellent service from Levi. Knowledgeable and friendly.

Paul and Andrew were very professional, and they patiently explained the finer details of the work when asked. I learned a lot from them. I also appreciate the company’s prompt response when things go wrong. I’m very glad I have a service contract with them.

The installers from Cosby went above and beyond what I expected. It's refreshing to see people take such pride in their work. Thanks so much.

Very pleased with the service we received from Paul. Got our furnace back up and running. Thank you.

Zack, Mike and Erick, removed our old geothermal unit and installed a new geothermal unit. These technicians at Cosby Heating & Cooling, were friendly, professional and very knowledgeable and thorough in their installation of our new unit. I highly recommend Cosby Heating & Cooling for your HVAC needs!

The receptionist was very kind and helpful and Levi, our service technician, was professional and very knowledgeable.

great company!! always reliable and very courteous

We have had Cosby Service for our boiler for about 5 years since moving to Mount Vernon. Each technician is very knowledgeable and explains exactly what service is needed. Then an estimate is quoted before our final decision. At this recent check of the system, John took time to solve the extremely noisy pipe issue that was waking us at night.

Levi was very professional, thank you very much for repairing our furnace as soon as possible.

Paul was very professional and just a nice guy. He was very knowledgeable and helpful in our decision to replace an aging system.

Thanks for taking great care of us! It is very much appreciated!

Levi Steele was an amazing service representative. He was extremely polite, well versed, honest, and informative. I would recommend Cosby Heating and Levi to associates seeking heating and cooling service. Thank you.

Very professional and polite young man he seemed to know his stuff

Levi was on time, explained what he was doing, and was able to give us quotes and times for furnace repair within a few minutes.

Andrew was very knowledgeable regarding my new ecobee thermostat

Excellent service and knowledge

Great customer service and technical expertise. I've had this company service my home heating equipment for years.

Great service from Carl every time! Also love that THEY call US to schedule check-ups under our maintenance contract, and don't just wait for us to remember to schedule them. Highly recommend.

Andrew promptly identified the problem keeping our furnace from running (attached humidifier had been wired improperly), explained it clearly, and had the furnace working again. We appreciate his friendly manner and expertise.

Paul was very professional courteous knowledgeable and arrived in a timely manner Also made me aware of discount on annual check ups.Thanks Paul

Levi Steele was outstanding in his service call today. He was knowledgeable, very pleasant, and suggested things that would enhance functionality of our HVAC. Cosby is a great company to work with. Every technician they have sent has been very knowledgeable and good to work with. I don’t know whether they are the cheapest, but if you want high quality you will get it from them.

Lee and Heather and the team completed some installation work at our house and we are pleased with the results. Thank you very much!

Cosby installed a complete new heating and cooling system for me on 11/15. They had thought it could be done in one day but when it couldn’t instead of rushing and possibly making a mistake they came back the next day and finished the job without rushing it even though their labor expenses were higher than they had planned. Thank you Cosby!!

My AC unit went out and Carl with Cosby Heating & Cooling had it fixed within 15 minutes of his arrival. He did a good job and made a couple recommendations, which I appreciated.

Carl, our technician, was excellent! So was Karen who helping with scheduling! Look forward to our next service with the multi-year Maintenance plan !

Excellent service. Very professional and friendly. Thanks

Very pleased with the timeliness, professionalism, and quality of work provided by Cosby HVAC on our Boiler

Today we received our furnace’s winter maintenance. Chris did a great job. He was knowledgable about how the furnace worked and how to maintain it. He was clean and acted in a professional manner. Thank you Chris for doing a great job!!

Came out the day I called, arrived on time, had all necessary parts on hand, and fixed our AC in one visit. Very reasonable prices!

Cosby replaced my mom's furnace. They did a wonderful job; came back on multiple occasion free of charge to check on it and sent her a gift basket with fresh baked cookies. This place is A+ greattt. I will be calling Cosby when I need any repairs.

They are very qualified and professional.

Called early and had a technician within 2 hours at our house. Problem was diagnosed and fixed within an hour because they brought parts with them. I am extremely impressed with the technician and his professional approach. When the job was complete he stayed and made sure things functioned properly. Highly recommend Cosby for great deals and speedy service.

Tech was informative and sincere and explained everything in great detail, not pushy about anything. Customer service when making the appointment was easy and follow up was immediate

No matter who Cosby's sends to our home we always get the best service in town!

Chris was on-time and very professional

Great service friendly and knowledgeable Andrew is very helpful!

Pool heater quit working. The pool company who installed it recommended calling an hvac company. The company I usually use would not look at it (even though it’s just a heat pump). So I called Cosby. Andrew came out (5days before originally scheduled), and immediately found and fixed the issue! Quick, professional, friendly, and reasonably priced service was our experience. Thank you Cosby!

Very satisfied with service. Honest, timely, professional.

very professional as usual

Zack was professional and friendly. Understood my needs.

Really impressed with the installation team. They showed up and kept after it until the job was done and the job was done very well. Very professional installation and phenomenal end-of-day cleanup.

Long standing customer. Will continue.

Andrew with Cosby was very professional and efficient! I would highly recommend them for your HVAC projects and repairs!

Very friendly and responsible

Very knowledgeable, arrived on time, quick response,

Carl and Brad did a great job and were very knowledgable in what they did and worked very well together, Thank them for me, Dave.

Always great! They have great communication, and they come when they are supposed to. Technicians are always very knowledgeable and kind. I cannot recommend them enough. 10/10

They did a great job. I highly recommend them.

Your representative, Zack, was friendly, knowledgeable, and used time wisely. Explained the process and future need very well.

John was great, professional, quickly found the problem and got our furnace going again. I would highly recommend Cosby heating and cooling to anyone in the area

We have been a customer of Cosby for many many years. They do an absolute wonderful job on everything. The technicians are very skilled and pleasant. Highly recommend this company to anyone.

We had an issue with our Rheem hot water heater. Zach came out - early - and diagnosed the problem and got us up and running again. This is our first experience with Cosby - but I'm sure won't be the last should we have any other issues with our various heating/cooling items. Thanks!

Yearly maintenance plan for furnace and water heater. Technician is very knowledgeable and does a thorough check up.

Excellent service every time.

Every single person that helped me to get a new oil furnace was wonderful. I am so grateful to Andrew who discovered a crack in my old furnace that prompted me to invest in a new oil furnace. My old furnace was emitting an unhealthy level of carbon monoxide.

This is the 3rd time we've used Cosby after inheriting a house with a furnace and HVAC serviced by them in the past. Every time they have been extremely late -- sometimes by multiple days. Responsiveness has been an issue, as they do not give initial times they will be there, meaning you will be waiting the whole day not knowing whether they will be coming in the morning or the afternoon. When you call, the time often slips from morning, to afternoon, to sometimes a totally different day. This seems like an issue with their scheduling, as it's chronic, and is a big issue when customers must lose countless hours and income waiting at home to receive no response. This last time we waited at home, losing a day's worth of income again, only to have Cosby come out after dark, after their office had closed, our children were asleep, and they were 2 hours past the last time we'd been given (we'd been given several times already that day, all slipped). I informed the tech we would not having them look at our furnace until we talked with management about this responsiveness issue (not to blame the techs; this seems like a problem above their pay grade), as it's become commonplace for us to have to schedule our *week* around a *day* that they're supposed to come out (as we've had them slip entire days twice now). To that they offered to "look at our furnace now, check it out, and send the bill later." Uh, no thanks? If I'm *losing* income due to waiting all day for a tech that doesn't show until after working hours, I'm not sure how footing the bill later will help make up any lost income from their lack of responsiveness. It's especially egregious as we've been without a furnace for over a week. Thankfully our wood-burner and space heaters have kept us afloat and will continue to as we look at competitors. Price-wise, Cosby's has been slightly higher than average. Not an issue, if the customer service and responsiveness side was better. As of right now, I do not recommend their service. I'll change my review if they make amends somehow, but I'm quite distrustful of their business at this point. Less

Cosby Heating and Cooling are great too have do your furnace work. They know what they are doing. They do a fantastic job

Very professional and courteous. Fully explained everything that was completed and checked. I feel comfortable that my service needs were met.

Brad was very knowledgeable, explained what repairs were needed and why, and went above and beyond to make sure our heating system was working better than ever.

Excellent reliable and dependable

Carl is an excellent technician.

Chris is a great technician. He was efficient in all aspects of his job and very friendly.

Great experience with Cosby! The guys arrived on time, were very kind and professional, made suggestions but weren’t pushy at all, and answered questions thoroughly. The service was unlike what you get from most places these days. I would highly recommend this business!

End to end experience was great; my technician, Zach, was awesome - explained what I had, what he was going to do, and even offered to have someone call me with some quotes for additional items I asked about. Overall awesome experience

Geothermal maintenance

Cosby's have always done great work for us. Technician John recently did our A/C system maintenance. He was very courteous, personable, and very clean in his work. He did a great job!

Next day service and completed entire job in less than 2 hours.

Brad is great! Very knowledgeable and fair.

Excellent thanks.

All I needed was a 10 inch piece of duct work and they were very helpful. It was only 10 bucks and they even crimped and cut it for me. If this is how they do business in the office I imagine thier tech are amazing in home. Thank you guys

Quick service. Good communication. Timely. Worked on a mini split. Technician was friendly and knowledgeable.

Cosby Heating and Cooling is the only company I use for HVAC. Excellent service at a fair price.

Cosby has been very professional, spending time up front to develop my HVAC options and help me budget for improvements, and then doing the needed work promptly and well.

We had an issue with our central air unit which required attention. Cosby's quickly came out, diagnosed the problem and fixed it immediately. The young man who arrived was polite, very neat inside the house and explained everything to me. Highly recommend Cosby's to anyone with Heating/Cooling problems. Reasonably priced and quick to respone.

Carl was very knowledgable and took time to investigate the issue.

Chris did a great job cleaning and maintaining our 2 AC systems. He did find a couple things that needed repair, and took care of that right away. He discussed some things he found and let me know some things to keep an eye on for next time. Thanks for taking care of our systems!

Zack is a top notch specialist at Crosby Heating & Cooling!

Cosby has been my go-to for HVAC service for several years now. They're always professional, courteous, friendly -- and on time.

Their service men are always very helpful knowledgeable and overall very nice.

Technician was on time and professional

Great work at a fair price. Can't ask for more than that.

During routine maintenance found issue that needed immediate replacement. Gave me options to repair or replace. Replacement made more sense. As it is cold here they were able to schedule the next week. On time and done very nicely. Customer Service Laura was able to answer all my questions. Everyone was very friendly and responsive.

Good service. Knowledgeable technicians. Good products.

Cosby provided a very complete and professional installation of our new geothermal furnace.

I really am thankful that he found it quickly. Thank you again. There are to many companies out there that would of taken advantage of the situation and fixed something that didnt need fixed. Thank you again. Will be using your service if needed in the future. Less

Great job! Thanks for helping me out! Ed

Andrew is a great service tech. He fixed our forced air oil furnace. Thanks for your help.

Josh was very informative & thorough. Cosby Heating & Cooling has always been great to work with!

Josh was a perfect gentleman, polite and informative. I learned so much and it feels great knowing our furnace had a thorough preventive maintenance session and minor repair. Husband is happy to find a company we'll feel confident and comfortable calling on for our HVAC needs. Josh's behavior toward me was truly appreciated by both of us. Great job team, from phone rep to tech!

They never bothered to return a call after leaving several messages

C H&C, FYI the remarkable woman answering the phone was very polite and very efficient. Same for the tech, Carl who met me on site. Bravo to the two team members mentioned here who helped take care of my situation 100% and who were EXTREMELY efficient and professional. - Kevin Reiner

Cosby was the third company to trouble shoot our furnace. They were the only ones able to find the issue! Everyone else tried to sell me a new furnace after costly replacement parts that were not the problem. Extremely prompt and professional from the first call to completion! Definitely will use and recommend!....(update 6/29/2022) Left a message for Cosby at 6:30 pm, my a/c fan was out. Got a ... More

Brad was amazing..He diagnosed and totally repaired, same day. This company ROCKS! Less

The representatives of the company were good professional individuals. Their customer service was excellent. Starts with the person answering the phone and scheduling the appointments (Laura), then the salesperson (Adam) then finally the individuals installing (Andy and his assistant). Thank you for a “Job Well Done”

Great technician and company!

Andrew, our technician, was exceptionally good.

Excellent service and Andrew is top notch in customer service! We have a boiler and Cosby keeps it going!!! Thank you!

Very competent and reliable company and technician. Have used them for years with two geothermal units

Professional and on time

I have had a great relationship with Cosby Heating & Cooling for many years as they installed a full HVAC system in our new home and fully maintained the system with regular maintenance over the years.

Josh was courteous, on time and explained everything he completed before he left. He went over the service agreement and emailed me promptly afterward with my copy. He respected my home, wore a mask and cleaned up after himself.

Always does a good job and very friendly. Would recommend to anyone needing help.

Great service.

Good service by a responsive technician!

They are responsive and efficient at solving your heating and cooling problems. I highly recommend them.

We have been customers for 29 years and always get great service.

Great company

Josh was great - on time and stayed until the job was complete. He clearly explained the process he was going to take to evaluate our issues, explained the issues themselves, and gave suggestions to address each issue. I really appreciated the time he gave to walk through everything with me in a respectful and professional manner. Strongly recommend!

Andrew and Josh were outstanding!!! They were very thorough and explained everything to me concerning our air conditioning system. I absolutely would recommend them!!!

The technician arrived on time and was friendly and competent.

Have used Cosby for many years and I highly recommend their service.

Cosby is very professional from the friendly phone contacts to the well trained technicians. Brad replaced a faulty gauge that was discovered during the last service call so the service call fee was waived for this repair. As we have come to trust, I was called before Brad arrived. He replaced the part easily. Hopefully we won’t need any service until our Fall checkup, but if we do we know to... More

75 to come out, 111 for repairs, time spent working, and parts/labor. I was also told they'd be out here after noon, they arrive by 10:30 in the morning. THANK YOU SO MUCH for fixing my air conditioner!

I've been a customer for 10 years. Cosby reps always open and honest and show concern for my needs. Technicians are trained and expert.

Andrew got my AC going after it had been down all weekend. I had to order a new control board but he still managed to get my air working until it could get here. Thank you so much Andrew....

Chris is polite efficient and quick. The was on time and did a great job.

Always professional and knowledgeable pleasant to have in our home
