    I had an issue with my air conditioning system, and after two companies came out with similar diagnoses and high prices, I called another service. The technician arrived promptly and quickly identified the problem. They replaced both my AC unit and furnace for a much more reasonable price than what I had been quoted for just repairing the AC by the other two companies. I felt no pressure to make an immediate decision, which was a welcome change. I would definitely recommend this HVAC service. They were professional, timely, and did excellent work. I'm very satisfied with the outcome. I also want to acknowledge the office staff who kept everything organized and updated me throughout the process. Their efforts did not go unnoticed. One happy customer!

    Came home to find my heater not working. I first called another company and was told that the control board was fried, the motor and compressor were gone, and there was a coolant leak, so I’d need to spend thousands on repairs or replacement. Wanting a second opinion, I reached out for another look. Terrance showed up quickly, acted professionally, and was very honest. He carefully checked everything and found that it was just a simple battery that needed replacing. Instead of a huge repair bill, my heater was working again for only $450. Very happy with the service and honesty!

    Jude and Terrance showed up right on time to look at our mini split heater system, which wasn’t heating as well as it should. Jude explained that the filters need to be cleaned every few months and made sure I knew how to do it myself. They also checked the coolant and noticed it was a bit low, so they tightened up the connections and added more coolant. After cleaning the filters and topping off the coolant, the heater is working perfectly again. I’m really happy with how everything turned out!

    If you need AC repair or help with your HVAC system, I definitely recommend calling this company! When we first moved into our house in Littleton, our air conditioning unit was pretty old, so we had them come check it out. The technician, Dean, was very upfront and honest about the condition of the unit, explaining what we might need in the future. He also shared helpful tips about taking care of the system, which we really appreciated. Recently, we started having trouble with our AC again, so we called them back. This time, Greyson came out and he was just as professional and straightforward. After inspecting the unit, he let us know we needed a new one, and they offered a really good price. They were able to schedule the installation quickly, and even though there was a small issue with the first unit being bent, they went out of their way to get another one and still finished the job that same day! Throughout the whole process, they kept us informed and made sure we were comfortable. Their service truly went above and beyond what we expected. If you’re in Littleton and need AC repair or HVAC service, you won’t find anyone better!

    As someone who has worked in HVAC for many years and also ran my own business, I have high standards when it comes to heating and cooling companies. I reached out to three different companies for a quote to replace my outdoor package heat pump unit. One company handed me a handwritten note with a price, and another promised to get back to me but never did. When I contacted this HVAC company, they impressed me right from the start. Jude came out exactly when he said he would to provide an estimate. He was very professional, explained all my options clearly, and gave me detailed information about the different HVAC systems available. It was obvious early on that this was a company I could trust for my installation. Jude gave me a fair price and scheduled the installation. When my old unit broke down unexpectedly during a heat wave, I called them in a panic. They managed to fit me into their schedule the very next day. The installation crew was excellent—punctual, respectful, and clearly knew what they were doing. I really appreciated that I wasn’t asked for any payment until the job was fully complete, and they also offered financing options. I highly recommend this HVAC company to anyone looking for great value and reliable service. When I had a minor issue with the new unit later on, Terrance from their service team arrived quickly, found a factory defect in a part, and had my system running smoothly again in no time. Excellent experience all around!

    AllSeason Heating, Air & Electric is highly recommended for anyone needing furnace repair. I’ve been using their services for years, and this time they really impressed me. My furnace stopped working on New Year's Eve, but Terrance showed up quickly to check things out. Although he didn’t have the part right then, he called me the next morning to see when he could come back to fix the furnace. I was surprised and grateful to get such great service on a holiday. Terrance was professional, friendly, and really cared about helping me. I’ll keep using their furnace repair services and hope this review helps others in Littleton find reliable help too.

    Dean was very professional and gave great customer service while doing routine heater maintenance, clearly explaining everything when he was done. I mentioned a problem with my outdoor thermometer affecting my heating system, and he explained that it should be on the north side of the house, not the south. He moved it to the right spot and showed me how to troubleshoot by pressing the reconnect button on the furnace, so I could keep things running if the issue ever happened again. I really appreciated the help from AllSeason Heating, Air & Electric.

    Preston, Greyson, and Dean were very professional and did a great job fixing my furnace. They were polite and made sure I understood how the new system worked. Greyson took time to explain the thermostat so I felt confident using it. Preston and Dean handled most of the installation and did excellent work. They laid out tarps, kept things tidy, and cleaned up everything before they left. The room with the furnace looked even cleaner after they finished because they took care to clean up the whole space. The entire process was smooth and positive. The person who helped me choose the furnace was very helpful and made sure I felt good about the equipment and cost. I highly recommend AllSeason Heating, Air & Electric to anyone needing furnace repair or installation.

    Greyson did an outstanding job during the recent maintenance of our heating and air conditioning system. He pointed out that the main system’s air filter needed to be replaced, thoroughly cleaned the heat pump, and checked over each unit to make sure everything was running smoothly. We’ve relied on AllSeason Heating, Air & Electric for many years, with regular service visits twice a year. The technicians are always on time, tidy, and provide a detailed evaluation of our entire HVAC setup. One winter, just before the holidays, we discovered a gas leak near our meter, which meant the gas had to be shut off and our furnace was out of commission. The technician quickly made sure our heat pump was set to provide enough warmth until the gas service was restored and the furnace could be used again. The team really knows how to keep us comfortable and safe, even in the cold Colorado winters. Always a great experience!

    As first-time homeowners, we were worried when our AC unit stopped working during a stretch of hot weather. After dealing with the warranty company for a while, we decided it was best to replace the whole HVAC system instead of just fixing it. We called an HVAC service company, and the technician, Preston, was very friendly and professional. Preston and his team showed up right on schedule and got straight to work. Within just a few hours, our new system was installed, the old unit was removed, and everything was cleaned up nicely. Now our home is cool and comfortable again, which is especially important in Colorado’s unpredictable climate. We are very satisfied with the whole process and will definitely recommend their HVAC services to our friends and family.

    Recently, my carbon monoxide detector went off at home, and after the fire department checked things out, it turned out the source was my old boiler. The next day, I had three different HVAC companies come by to give me quotes for a replacement. I was especially impressed by how detailed and clear Preston's quote was. He explained all my options for a new unit, walked me through the process, and patiently answered all my questions about ac repair and heating. I decided to go with this company, and they started removing my heavy old boiler right away. Preston and Terrance came back soon after to finish the installation and make sure my heat was running smoothly. They did excellent work, explained how my new system operated, and left the area spotless—cleaner than when they started! I’m very happy with their ac and heating repair services and will definitely be calling them for regular maintenance, especially when Colorado winters get cold.

    I only have great things to share about this heater repair company, which was recommended to me by a neighbor. My furnace stopped working, and I called them to check out the problem. Dean was very polite and explained my repair and replacement options in a clear way, without pushing me to decide quickly. He also answered all my follow-up questions, which made it easier for me to choose to replace my old furnace. The company was very honest about their pricing, which was reasonable and matched other quotes I got. On installation day, Greyson, Dean, and the rest of the crew were professional and worked hard to finish everything on time. Dean and Greyson checked on the progress several times during the day and kept me informed. My new heating system is working perfectly, and the team has continued to be helpful whenever I had questions afterwards. I’m very happy with the service and would recommend them for any heater repair needs.

    I recently had a new furnace installed at my home. Preston and his coworker were very professional and knew exactly what they were doing. They handled a tough heater replacement quickly and at a fair price. The team was able to schedule the installation just a few days after giving me the estimate, and they kept me informed the whole time. Preston went the extra mile to make sure everything was up to code, even installing extra smoke detectors I needed for safety. I highly recommend this team for any heater repair or furnace installation work.

    I scheduled an appointment to have a technician look at our gas furnace since it’s our first time having gas heat in a home. The technician, Preston, arrived and was very knowledgeable about heater repair. He took the time to explain how our furnace works and what had caused an error code I saw last winter. Preston made some adjustments so the problem wouldn’t happen again and also checked everything else to make sure our furnace was working safely and efficiently. He also gave helpful advice on which filters to use. I will definitely keep using this company for any future heating or air conditioning needs.

    when my 20 year old furnace suddenly stopped working, i realized it was finally time for a replacement. after talking things over with preston, he explained that it’s usually a good idea to replace the a/c system at the same time, especially since both were the same age and would help my home stay comfortable during colorado’s changing seasons. at first, i was hesitant, but after learning more, it made sense for energy efficiency and long-term savings. i reached out to a few different companies, compared estimates, and did some research on various hvac brands and equipment. some places tried to pressure me, but i never felt that way here. preston was super knowledgeable and honest, guiding me through my options and never pushing me into anything. the estimate was clear and straightforward, with no hidden costs, and the follow-up was excellent. every time i called with my many questions, the office staff was patient and helpful. overall, the whole team was easy to work with and trustworthy. i highly recommend them for any heating or air conditioning needs.

    i recently had Dean come out to check on my hvac system in Littleton and he did a fantastic job. i got a text when he was heading over, and after the visit, all the paperwork, pictures, and invoice were sent to my email, which made everything super easy. dean really took the time to explain how to keep my older unit (it’s about 22 years old) running smoothly, and he was focused on helping me understand my options for the future instead of just trying to sell me a new system. he also has a lot of experience working with rooftop hvac units, which isn’t always easy to find around here. i highly recommend reaching out for any hvac services you need.

    If I could give this furnace repair team a thousand stars, I definitely would! Every step of the process—from the helpful office staff to the knowledgeable sales folks, skilled technicians, and even the owner—was fantastic. Everyone I spoke with was friendly and really knew their stuff about furnaces. Preston came out to our home to take a look at our old furnace and provided a detailed written estimate for a new one. He took the time to check out the system, test everything, snap some photos, and patiently answered all of our questions. He also gave us helpful recommendations for what would work best in our home, especially with Colorado’s cold winters. Once we scheduled the installation, the communication was excellent—we got reminders and knew exactly who would be leading the installation team. On the day of the furnace install, the crew arrived right on time and worked efficiently. They made sure to clean up thoroughly before they left and didn’t rush out the door. Preston explained how our new furnace worked, showed us the upgraded thermostat, and gave us some great tips for keeping everything running smoothly and efficiently during those freezing Colorado nights. The whole process was straightforward and stress-free. We’re so glad we chose this team to handle our furnace replacement, and we highly recommend them to anyone needing heating services!

    I can't say enough positive things about my experience with AllSeason Heating, Air & Electric. When I needed AC repair in Littleton, Jude and the team really impressed me. They were polite, quick to respond, always on time, and the quality of their work was top-notch. True professionals from start to finish! Our air conditioner stopped working right when the weather started heating up, but Jude made sure someone came out right away. With a big family, having cool air in the house is a must, and they understood how urgent it was. The issue was diagnosed quickly, and they clearly explained the repair process, keeping me updated the whole time. The technicians were friendly and knew exactly what they were doing. They were also very clean—both in how they worked and in tidying up after the job. Overall, it was a fantastic experience. If you need any AC repair or HVAC work, this is the only company you need to call!

    After a different company told me my furnace needed to be completely replaced for thousands of dollars, I decided to get a second opinion from AllSeason Heating, Air & Electric. Preston came out to check my furnace, and quickly found that the only problem was a small leaky hose—nothing major at all. He made the repair for a much lower cost and explained that my furnace still has plenty of good years left. I really appreciate the honest advice and trustworthy service. I highly recommend them for anyone needing furnace repairs.

    I was really impressed with the AC repair service we received. We reached out on a weekend when our air conditioner stopped cooling, and they sent someone out quickly to check it out. Preston, the technician, listened to what we had already tried and explained how it helped with the AC unit. He did a thorough inspection and found that the issue was with the refrigerant flow, which was causing the cooling problem. He fixed it right away and clearly explained how we could spot similar issues in the future. Preston was very knowledgeable and took the time to teach us during the visit. Everyone we spoke to was professional and showed great customer care. They arrived on time and did everything they promised. I highly recommend them for any AC repair needs.
