Our newly blown-in fiberglass insulation had clogged up the air handler in our attic. When I called Plumbline Services to have my 13-year old system serviced for their advertised $39, Plumbline told me it would cost about $2000 to do that, partly because we would have to replace refrigerant completely to the new kind (at $480/ pound, per them), and then upon inspection of my condenser, proceeded to list the thousands of dollars it would cost to do all kind of things to the condenser because this was rusty, and that was loose, and on and on. I then started a full-blown search to find a new a/c system (condenser and air handler since we have steam radiator heat). I contacted seven companies in total. I consistently saw uniformed service (or should I say sales) people come brightly painted vans give me a presentation, take a cursory look in my attic and outside, and quote me an average of $10,000 for a new system. I figured that seeing the 7th company representative would give me more of the same, and I almost canceled the appointment, but I am glad I didn't. When the Comfy Cave person, Mark, I believe, came, he made observations that nearly no one else did, offered to fix the attic condenser for a few hundred dollars if I preferred (new refrigerant quoted at $120 pound), and said that all he wanted to do was make me happy, I decided that I liked what I was hearing so far, and to take advantage of existing Xcel rebates and be done with the process once and for all, I said I would prefer a new system. He gave me a quote for many thousands less than everyone else. And, the system he specified was slightly more powerful in total than the others. The condenser was installed first, and due to a two-week back order of the air handler, Von, the owner, agreed to somehow get my old air handler to work with the new condenser.,,for no additional charge. That was music to my ears especially because weeks ago, I had originally not been in the market for a whole new system when first I called for servicing. Then, shortly thereafter, I had a snafu, not due to Comfy Cave, but to my plumber. He had capped the pipe which served to drain the old air handler, and soon the water filled up in the pipe which was in the wall, and I had water damage to my plaster wall and ceiling. When I called Tammy who is the able in-house manager, she connected with Von who immediately had someone who was training come over and go into the attic to sop up the wet fiberglass...at no charge to me, again. Then, when the air handler arrived and was installed several weeks later, there was a water sensor issue the day it was installed. The unit seemed to go dead (actually it stopped as a safety feature because it sensed water near the attic air handler), Von offered to come same day later in the evening from south Denver to get it rectified. Now, I know they don't do off hours calls, but this was directly due to the installation not being completely worked out. I declined because I thought it was too much to ask, so he appeared quickly the next morning to get the issue resolved. Since then the system operates great. I am happy with the variable speed air handler and the condenser. I am very, very happy with the unbelievable support I got that I didn't even know I would be needing to switch to a new system. Everyone I dealt with in this 7-person company was competent and polite. I am now referring my son to them for some needs he has. Now this is how to build a business! read more

Yet another miracle from Comfy Cave! My mother's AC needed repairing last year. The initial HVAC contractor told her the AC equipment had to be replaced for ~$6,500. I called Comfy Cave for a second opinion. Comfy Cave called me with "good news and bad news". Good news: The problem was low coolant (freon?) charge. Bad news: It's the old style compound so it's going to be expensive to charg. Like ~ $200!! A $6,300 savings. It's been fine ever since. My AC unit was not able to cool the house even though the equipment is properly sized (5 ton). In the past, I was hesitant to call an HVAC company for fear of getting overcharged. I tried everything myself; 1) added vents, 2) insulated ductwork,.. Finally, I called Comfy Cave. Von checked everything and concluded the equipment was fine. Let me see your filter.... "this filter is way too dense. Let's try the system without it." SOLVED for a nominal fee! I asked Von to check out my old compressor outside. Great quotes from Von: 1) some people will see this equipment and say, "It's old and needs to be replaced" 2) there is no reason old equipment should't work just fine. 3) It's my nature to want to fix things Cannot say enough good things about Von and Comfy Cave. I don't look forward to HVAC issues, but I do look forward to working with Comfy Cave again! read more

We recently had the pleasure of working with Comfy Cave Heating & Air for the installation of a new Goodman Air Conditioner, which we had already purchased. From start to finish, the entire experience was smooth, professional, and hassle-free. Tracy and Mike arrived promptly on the scheduled day, and they were respectful of our home, taking great care to ensure everything was installed correctly. They had all the necessary equipment and tools, and they were very efficient in getting the job done. It was clear that they were experienced and knowledgeable, as they carefully explained the installation process and made sure all the details were addressed before completing the work. They also took the time to show us how to use the new system and answered all our questions, making sure we were fully comfortable with the setup. What impressed us most was their attention to detail and their willingness to go the extra mile to ensure everything was perfect. The AC is running great, and we couldn't be happier with the results! We would highly recommend Comfy Cave Heating & Air to anyone looking for reliable, professional HVAC services. They provide excellent customer service and top-notch work at a fair price. We will definitely be using them for any future HVAC needs! read more

Von and the team are the best. I've had them do swamp cooler restarts, motor replacements on a rental and then work on my main house . Last year they squeezed me in before the weather got really cold, when my 1980 furnace started to take a dive. I had two small kids under 2, so I was worried about reliable heat in my 1889 Victorian. Von and the team came over quickly and provided a reasonable bid, lower than some others I thought were out of line. They replaced my unit quickly, swapped all my lower ductwork, added a few new returns and we got a return as close to the upstairs as possible. The house is noticeably more comfortable and consistent since they installed and adjusted my unit. I highly recommend them for your needs. They helped me deal with Xcel over the course of 6 months too while they messed around with my $850 rebate. Xcel kept punting the issue claiming I had a commercial property (residential home here that I live in) and coming up for reasons to not process it. Comfy Cave's office was persistent in assisting my requests and supporting documentation whenever Xcel came up with something "else" they wanted. Customer service star award from me read more

From my initial call, Dorothy set the tone for Comfy Cave as a positive, upbeat company. She was accommodating, professional, and personable. She addressed my needs, and even let me know upfront how much that particular service would cost so there were no surprises once the tech got here. Jeremy was sent out to clean and check my furnace and was awesome! He called 20 minutes prior to our appointment to confirm and let me know he might be a couple minutes late. He actually showed up right on time, but it showed respect for my time that he gave me the heads up to begin with. Once he got here, he was very thorough and still in and out within an hour. He was kind, courteous, and respectful the entire time he was here. He never talked down to me and was nothing but professional. I have dealt with companies that may get the job done, but are rude and disrespectful in the process. There is no need to settle for those companies when there are companies like Comfy Cave out there. I will definitely be using them in the future for my heating and air needs! read more

I have never had such excellent service! My hot water heat stopped working and I called my usual service company on Tuesday and was told nobody could come out until Thursday. The outside temperature was six degrees! I did set an appointment for Thursday but on Wednesday it was three degrees so I thought I might find somebody to come that day. I read the reviews on Yelp and called Hillary at the Comfy Cave. She was amazing and although she didn't think it could happen that day, she called other plumbers to find an opening but was unsuccessful. She offered to bring over some space heaters to help me through the night. Fifteen minutes later she called again and said that Von (company owner) would be over that evening between seven and eight and, true to his word, he repaired the boiler for a reasonable price. I cannot recommend this company highly enough. They are amazing! read more

Our air-conditioner had been limping over the last three years. We finally bit the bullet and decided to get a new one. Michael M did the initial diagnosis and was here for the installation as well. Comfy Cave recommended SJO Electric for the "up to code" work though not a requirement. The choice of electrician was up to us though we chose to work with SJO as well. We were not disappointed in the entire process. It was seamless from start to finish in making the appointment and coordinating between the two teams who came on the same day. Professional and personable, we could not have been more pleased as we hit 90 degree weather with our air-conditioner that is great looking and quieter than our old one that also had the heat coming out of the sides instead of straight up. We can now use our small patio so much more comfortably and the house feels great! read more

There seems to be little I can add to all of these glowing reviews of Comfy Cave. They do excellent work. Their techs have always been competent, friendly, and willing to take the time to explain what they were doing and what shape they thought my furnace was in. I've never had the feeling that they were trying to sell me something. My furnace went out once outside of business hours when it was cold outside. Forlorn, I left a message on their answering machine. To my surprise, my message was promptly answered, and a tech was out soon to fix the problem. My cave was comfy again. I trust Comfy Cave, and feel that their prices are very reasonable for the quality of service they provide. Finally, I love their philosophy of treating customers not just as customers, but as people. read more

I called Comfy Cave to have someone come out and service/inspect my furnace which was 20+ years old. Ricky came out to do the inspection and informed me that CO2 was leaking from my furnace. He advised me on my options, but never tried to push a new furnace on me. The guys who installed my new furnace were prompt, professional and courteous. Vonn, the owner, came out to do a quality inspection and made a few adjustments. He came out again when I called with a few questions about minor issues I was having. They responded quickly to my inquiries (both via email and phone), made the project and inspections convenient for my work schedule and did an all around great job. I felt the pricing was reasonable. I would definitely recommend the folks at Comfy Cave. read more

Von, Don, and Al of Comfy Cave are absolute Rockstars. These guys are extremely knowledgable, professional, and an absolute pleasure to have around. They went out of their way to help me replace my furnace, and offered very fair prices for quality work! I'm very satisfied with the new high-efficient Rheem R96V, the two-stages work seamlessly; the system kicks into the second stage after 10 minutes if the target temperature has not been reached. Comfy Cave is the way to go, I am so happy I didn't settle for another heating company. This time I actually did my research, and found Von through friends' recommendations. Von also submitted the purchase to Xcel Energy and my new Rheem 96% efficient furnace qualified for a $400 rebate! Thank you so much! read more

The owner of the HVAC company we used recently retired so we had to find someone else to perform the annual service on our boiler. During my research, I read all the positive feedback about Comfy Cave and decided to schedule an appointment. Tracy came out to look at our 50 year boiler He was very thorough with the checkup and very professional. During the inspection I was looking over his shoulder to see what he was doing and asking questions. He didn't seem to mind and in fact wasn't bothered at all with my observing. I was very pleased with his professionalism and appreciated his wearing a mask the entire time due to the fears of the COVID virus. I will call them in the future for any heating issues.

Responsive and friendly. Comfy Cave goes well beyond what is typically expected. Our boiler required a new pump and when asked how long it would take to order the part, Von informed us that he could complete the repair immediately. Von and his colleague stayed well after business hours until all was working properly again. They were very patient with mapping our rather complex set of pipes, valves, and pumps integrating solar, traditional water heater, and a separate boiler. Yes, all replacement parts are expensive, though Von graciously discounted his time and effort. I have no hesitation to use Comfy Cave again . . . hopefully not too soon! . . . and I recommend Comfy Cave to anyone reading the review. read more

I was referred to Comfy Cave by my hairdresser...And they were wonderful...They actually exceeded my expectations. When I called to make an appointment for fixing my air conditioner the message said they were 2 weeks out on appointments, but there was a cancellation and I was able to get my air conditioner fixed within 3 days! AND BONUS, Michael was so knowledgeable. Although he pin pointed the issue almost immediately, he spent time explaining it to me. He also showed me how to replace my filters correctly. I was extremely impressed with the honesty, knowledge and timeliness of this company. I will use them for all of my heating and cooling needs. read more

I had such a positive experience with Comfy Cave. From the moment I reached out, they were friendly, responsive, and easy to work with. The technician showed up on time, walked me through what needed to be done, and made sure I understood everything before starting the work. They were professional but also personable--it felt like they really cared about doing the job right, not just getting in and out. They kept everything neat and clean, which I really appreciated. It's hard to find companies that are both trustworthy and great at what they do, but Comfy Cave definitely fits the bill. I'd absolutely recommend them to anyone needing HVAC help. read more

Von Etzwiler (Comfy Cave Heating & Air) should be wearing a cape, because he definitely is my super hero. On a bitter cold Sunday our furnace stopped working (of course). Von was out of town, but as soon as he got back that evening, he called to say he was on his way. He quickly diagnosed the problem and, lucky for us, he had the part in his van. Soon he had our furnace back, up and running, and for an amazingly reasonable price, especially considering it was a Sunday evening service call! And we've been toasty warm ever since. I would definitely hire Comfy Cave again, should the need arrive, and I recommend their services with enthusiasm. read more

Love these guys. My hot water heater was leaking (never a good sign) and they came right out. Wound up needing a new one and they got me into the schedule within a couple days. They also showed me how I'd gotten ripped off the last time I had it replaced (in around 2005) - the other company had installed a hwh that was already 10 years old when the put it in. Comfy Cave also replaced the water valves into the heater, explained things that I never knew about the operation of my hwh, took pictures of the insides of the water pipes so I could see what is happening, and left everything neat and clean in the end. I would hire them anytime! read more
