Chris has serviced our HVAC system several times, and I couldn’t be more pleased with the results. From the start, he’s always professional, courteous, and efficient. He clearly explains everything, completes the work quickly, and leaves the area spotless. My system is running smoothly, and the pricing is reasonable and transparent, with no hidden fees. I highly recommend CG Heating & Cooling for anyone in need of reliable HVAC services. Thanks again, Chris, for your excellent work!

I had a wonderful experience with CG Heating and Cooling. It happened to be a very hot day and my a/c was making a ton of noise (and also not working efficiently). I contacted Chris and he was able to get to my place, determine the problem, and remedy it, all within a few hours. I’m pretty confident most companies couldn’t have done this so quickly. I will definitely use this company any time I have heating or a/c issues in the future.

I was pleased to call CG Heating and Cooling. Chris did an excellent job of diagnosing and reposting my in whole house humidifier. He was quick, efficient, professional and his price was fair.

I had them replace my evaporative cooler with a Breezaire cooler. It works great. He was very professional with giving me a written estimate and bill. The estimate wasn’t more than the bill. They cleaned up after the job was done, not leaving any trash or mess.I had another local company give me and estimate on what I wanted done but said they couldn’t run the extra vent to the living room of the house.

CG had entered into our lives as strangers willing to assist in a families time of need and left as part of our family. A complete explanation was given, was told exactly what was going to happen and treated with the utmost professionalism. CG was also much more affordable than the competition. Extraordinary service and incredible follow up. CG is now the only Heating and Cooling service we will use. Thank you CG!

His attention to detail and dedication to his work were truly impressive.Not only did Chris resolve the problem quickly and efficiently, but he also went above and beyond to ensure that our system was running perfectly. He even offered tips on maintaining the unit to extend its life and keep it functioning optimally. It's clear that Chris takes great pride in his work and genuinely cares about his customers' comfort.What stood out the most was his honesty and transparency throughout the entire process. There were no hidden costs or surprises—just top-notch service at a fair price.

Thank you CG for replacing my furnace. I really appreciated the time that Marty spent explaining to me the different options that were available to me. I didn’t realize that there were so many efficiency options and I am glad I went with the modulating Trane furnace. This furnace is so quiet and my comfort level is unreal. No more switching the thermostat up and down trying to find the sweet spot. Set it and forget it. Marty was right as he completely understood what my wife and I were looking for and at a fair and affordable price. I will recommend you every chance I get. Thank you again.

Chris was professional, quick, and a pleasure to work with! He provided two options that best fit our needs and was able to order parts and install almost immediately. I highly recommend Chris for your heating and cooling needs!

Absolutely first class service. Chris, the owner, solved my late December crisis when my 28 year old furnace quit. I got 4 separate quotes and it became apparent that Chris understood my needs and did not try to sell me "bells and whistles" unlike the "marketeers" from the other HVAC companies. Chris installed a 2-stage HVAC plus a water heater at a competitative price. I love my new system.

Justin Tyler

16:48 30 Apr 24

Chris was awesome to work with and went above and beyond to make sure the job was done right. His prices were reasonable, he was very punctual and he is a down to earth guy that was very respectful while in my home. I would recommend him to anyone!

CG Heating and Cooling, led by owner Chris, has become our trusted go-to for all things HVAC. Chris's expertise and dedication shine through in every aspect of his service. He not only rescued us from a problematic HVAC system installed by a competitor but also ensured its flawless reinstallation, optimizing efficiency and performance. What truly sets Chris apart is his commitment to customer satisfaction. He doesn't just fix the immediate issue; he takes the time to educate and empower his clients to maintain their systems for long-term reliability. Chris's approachable demeanor, technical proficiency, and genuine care for his customers make CG Heating and Cooling our top choice.

Highly Recommend CG Heating and Cooling!Why? Integrity. Exceptional Workmanship. First-Class Client Service. Affordable.Our 2019 (new-build) heater quit on Thanksgiving 2022. Chris (owner) showed up the very next day. He was efficient & thorough in his assessment, finding it could be a few issues causing the problem. Chris offered repair options, explaining he's mindful of clients' pocketbooks. I chose a more conservative option. Chris noted our motor was under warranty (I didn't realize this), so if the less expensive fix I started with didn't work, then he could replace the motor for labor cost only (nice!). Chris showed me his work every step of the way and taught me about my furnace (also nice!). Chris' pricing is very reasonable and he answered any questions I had afterward via text.I also decided to hire Chris to do a furnace clean/check w/blower removal & wheel cleaning because it was apparent whoever our builder hired to clean the system did a terrible job (or it just didn't happen). Same experience - Chris showed me every part, explained how they work, what he was doing - and it didn't cost me an arm & a leg.Fast forward to January 2023, the motor started in again w/the same problems. Chris got the replacement warranty motor ordered & installed ASAP. He even came back to adjust an exterior vent the builder didn't position properly without charging me for his time or labor!

Chris came out the morning that I called about our furnace not working.He got the parts and repaired the furnace the next day.Responded to a furnace question and spent a great deal of time troubleshooting and diagnosing the problem.

Had a fantastic experience working with Chris. He made time in his busy schedule to assess and fix a problem we had with our furnace as a last-minute project before we left out of town. He was very understanding, very professional, and very fair with what he charged (I thought he should have charged us more). You won't find a more honest and caring individual. We will be using him for all of our future hvac needs.

Peg Jacobs

21:06 30 Sep 22

Chris is helpful, knowledgable, fair, professional, prompt, clean, organized, he gave me several options at different price points and he answered my numerous questions. He had a guy named Marty working with him and he also is good people, you feel comfortable with them in your home, you feel comfortable that they are doing what needs to be done.

Lee Sutkowi

Chris was great to work with and went the extra mile to track down a new part the same day of the service.

I called to request service to repair our air conditioning system that wasn’t working because the fan wasn’t blowing. He said he couldn’t come out until Monday but to try turning everything off because the system may be frozen. I did what he suggested and six hours later the air-conditioning system is working fine thank you so much and I will call you with our future needs!

Kim Bennett

When you make a large investment in your home for item(s) you know absolutely nothing about one is quite vulnerable to the person selected to implement these items. I can say with complete confidence that my experience in working with Chris to assess, select, and install 3 major pieces of equipment into our home was as good as one could ever hope for. I've experienced working with the larger HVAC companies and always felt I was at the mercy of their technician. I had no real trust that they were an expert nor "cared" about the longevity of their work or product. None of these things could be farther from my actual experience with CG Heating and Cooling. Chris was extremely prompt with his estimate and even undercut the competitor by at least $1,500. Not to mention he installed a better brand but also the best size equipment for our home. He was incredibly efficient, tidy, and friendly and took the extra time to ensure we were experts in operating our new heating and cooling system. If you want to feel confident that you're getting the best quality, workmanship, and equipment for your home there's no question Chris is the best choice!

Quick response, tech did quality work and really took time to make sure things were done right. Definitely use them again and recommend.

Furnace went out on Super Bowl Sunday. Called several furnace repair shops and either no one was available or no one answered. CG Heating and Cooling answered right away and was over at my house shortly thereafter. A quick diagnosis was done and he had the problem fixed right away and we had heat once again.

Aaron Garner

Chris has helped a couple of clients of mine and they were thrilled at his knowledge and expertise in Furnaces and Air Conditioners. They both said he left the job site cleaner than when he started, and talking to Chris a few times myself he is absolutely now my go-to guy for everything HVAC related. Thank you for exceeding my expectations.
