HVAC reviews in Littleton, Colorado

I usually don’t write reviews, but I had a great experience with 4Seasons Heating, Air & Electric and wanted to share it. I needed urgent furnace repair, and Justin helped me get scheduled quickly. The technician and his team arrived on time, showed real professionalism, and clearly explained everything they were doing during the repair. My old furnace stopped working right when the weather was getting cold, and replacing it made more sense than fixing it. From the first assessment to the final installation, everything was handled fast and at a fair price. The whole process took less than two days! I really appreciate the excellent service and will definitely recommend them to anyone who needs furnace repair or installation.

we have trusted this company for all our heater repair and maintenance needs for a long time. every time, we've been really happy with how friendly and quick the service is. recently, our carbon monoxide detector went off, and when i called, they sent one of their experts, wyatt, to our house in just 10 minutes. unfortunately, it turned out we needed a new furnace, but the installation was easy and stress-free. wyatt and his team did an amazing job getting everything set up. everyone i've talked to at this company, from the receptionist to micah, has always been helpful and made sure our heating needs were taken care of. i highly recommend them for any heater repair in colorado, especially with how cold it gets here.

I had a problem with my air conditioning when it was about 85 degrees outside. Ashton came out to check my system and got it working quickly. The AC was low on refrigerant, and Ashton explained each step as he worked. I decided to sign up for their maintenance agreement, and Ashton returned a few days later for the service. He even brought the metal filters we had discussed earlier and showed me exactly how to clean and install them. I’m really happy with how professional and helpful they were. I feel confident that my HVAC system will be ready for both the hot summers and cold Colorado winters. They definitely deserve 5 stars!

i had a really good experience when i called for heater repair in Littleton. my heater wasn’t keeping the house warm, and sometimes the temperature would drop even when the thermostat was set right. i appreciated that the company understood how important it was to get heat working fast, especially with how cold it gets in Colorado, and they came out quickly. they sent a technician named micah, who was super friendly and really knew his stuff. micah took his time, checked everything carefully, and found a problem with a leak in the system that was causing me to lose heat. he repaired the leak the right way and made sure everything was set up correctly before he left. he also explained what he was doing step by step, which helped me feel comfortable. since the repair, my heater has been working perfectly and the house stays warm and comfortable. the price was fair and the service was reliable. i definitely recommend this company to anyone in Littleton who needs heater repair or service!

After finishing a six-month renovation on our house in Littleton, we can honestly say that working with 4Seasons Heating, Air & Electric has made all the difference. They installed a ducted Mitsubishi mini split AC system in our unique 1930s home, and the results were impressive. The system kept us comfortable even during the hottest days, performing better than the central air in our newer house. The installation crew was professional, paid close attention to our needs, and delivered excellent workmanship—special thanks to Ashton for making sure everything was just right. We also needed repairs on our hot water baseboard heating system, and Wyatt quickly found the problem with the valves and replaced them efficiently. He stayed afterward to test the system and made sure it was running perfectly, which gives us peace of mind for the next cold season. In addition, we had a variety of plumbing projects that needed attention. Justin managed all of them with skill and was great at explaining each step of the process in simple terms. He was friendly, professional, and very knowledgeable. Renovating an older home can be stressful, but having such a reliable HVAC and plumbing team by our side made everything go smoothly. We're grateful for their expertise and would recommend their services to anyone in Littleton looking for quality heating, cooling, or plumbing work.

Our furnace was barely working and we were worried about carbon monoxide in our home. I called for furnace repair in Littleton and the office was quick to respond. I explained what was happening, and they made sure to send a technician out that same afternoon. Wyatt showed up right on time, just a couple hours after I called, and quickly checked our basement. He discovered high carbon monoxide levels due to our failing furnace, which was starting to affect the rest of our house. Shortly after, another team member came out and gave us a fair estimate for a new high-efficiency furnace and water heater. I agreed to the proposal, and the very next morning, Justin and Jaime arrived early to start the removal and installation. They got started before regular business hours, which really impressed me. Both technicians were friendly and kept me updated throughout the process. Our new system was up and running in less than two days from when we agreed on the price. Even though it was our first time working with this company, they treated us like a priority and made the whole process easy and stress-free. They were responsive and professional every step of the way. The work area was cleaned up at the end of each day, and they even brought over extra space heaters to help us stay warm during the cold Colorado nights while the new furnace was being installed. Overall, I couldn’t be happier with the service we received. The team was professional, thoughtful, and made us feel like valued customers. I would absolutely recommend them to anyone in Littleton needing furnace repair or HVAC services.

Absolutely impressed with the professionalism and expertise! Our furnace started acting up, so we called 4Seasons Heating, Air & Electric after hours. The dispatcher quickly took our information, and their technician, Wyatt, reached out soon after to better understand the issue. Wyatt knew right away what needed to be fixed and set up a repair appointment for the next day. He arrived on time, was very knowledgeable, and explained everything about the furnace repair in simple terms, making the whole process easy and stress-free. We’ll definitely be scheduling a furnace tune-up before the cold Colorado winter hits. Highly recommend for anyone needing reliable furnace repair!

I had a fantastic experience with 4Seasons Heating, Air & Electric when my AC system suddenly stopped working. After calling for a quote on a new air conditioning setup, I spoke with Wyatt, who was very thorough and patient as he answered all my questions and worked out the details with me. Communication was clear and easy throughout the process. We have two AC units in our home, and I was looking for the best balance between energy efficiency (SEER), price, humidity control, and better air quality. Wyatt took extra time to understand what I needed and explained all the options. I was happy to find out their pricing was very competitive compared to others. Once we made our decision, Wyatt clearly explained what would happen next and set good expectations for the installation. On install day, Ashton, Jaime, and the rest of the crew arrived as scheduled and worked hard to make sure everything was set up perfectly. They brought their own food and drinks and stayed focused on the job. They took great care to protect our home, covering all the carpets and making sure nothing was damaged. Before leaving, they walked us through how the new system works and made sure to clean up everything. I highly recommend this team to anyone needing AC repair or installation. I’ll definitely be a long-term customer!

I wish the tech had showed me how to access and order the filter for the humidifier. That would have been helpful

Our AC kicked the bucket right in the middle of the hottest part of the Colorado summer. We shouldn't have been surprised, it was over 20 years old. We called Blue Spruce and they were fast, courteous and didn't complain about having to install in our cramped crawl space. They installed an all new HVAC in just one day and now we're enjoying very cool temperatures in our home! And we expect to be cozy warm this coming winter. Thank you, Blue Spruce!

The owners Jeff and Allison were quick to respond and Jeff came out to take a look at our project and was super nice and helpful. The quote was very reasonable and on the day of install; Jordan, Billy and Adam did a great job! They were knowledgeable, professional and cleaned up thoroughly once the install was complete. We are very happy with the result. I would highly recommend Blue Spruce for your heating and cooling needs.

I submitted a quote request through Yelp on a Sunday, and received a quick email reply. I had explained our heater issue, and their reply included the likely issue, which I was able to address for a short-term solution overnight. (It had just gotten cold.) I spoke with Allison the next morning, who was so helpful, considerate, and cheerful. She arranged for Jeff to come out during our preferred window of time, and he was very experienced in discerning the issues and repairing. He is very good at what he does, and was patient in listening and explaining how things work.
I very highly recommend Blue Spruce!!! A very positive experience throughout.

We had Blue Spruce replace an old furnace, water heater, and install AC to our system. They do amazing work at very reasonable prices. The owners are very hands-on and are great about answering questions, making helpful suggestions, and letting you know how and when things will get done. Their approach was definitely "do it right" rather than just "get it done." Their work is so good, that their work passed both the electrical and mechanical building inspections with absolutely zero issues. The owners Jeff and Alli are responsive and the installers (we had Rich and Carl) are experienced and very professional. I highly recommend this company. Quality equipment, quick response time, and professional work at a reasonable price. Can't get any better than that.

I just can’t say enough great things about Blue Spruce. Communication was clear and quick, and the pricing transparent. Adam, from Blue Spruce, was fantastic! He was on-time, did a really fabulous job on our swamp cooler and was very nice and flexible to work with. Thank you, Blue Spruce!

Blue Spruce replaced my furnace and added air conditioning to my home almost two years ago. The owner, Jeff, was helpful, personable and knowledgeable. His wife, Allison, is responsive when I leave messages and very kind. They came on time, worked with what I wanted to have happen, were professional and exceed my expectations. Last spring they came back to do a check on my furnace and AC for the season and this year they did a housecall for my furnace. I did a lot of research before choosing a company and this is a great one.

Adam was great and took the time to explain everything to me, even the more technical bits. He was very respectful of our space and offered great guidance on how to keep our system running well. Blue Spruce will always be our first call!

Blue Spruce is a family owned company and they are amazing. The owners, Jeff and Allison have a team of highly trained technicians who are knowledgeable, professional and talented. We have used them for our nonprofit business for years, and they've never let us down. They have done everything from installation of a brand new rooftop unit all the way down to Minor repairs. We wouldn't use anyone else. I highly recommend them for your residential or business needs. Great Job Blue Spruce!

Blue Spruce was very responsive to a problem with my air conditioning unit that they installed several years ago. They came out and diagnosed the issue the next day and then when the ordered part arrived, they came out promptly to install it. I was only a few days without air conditioning. Very happy with their service and their polite and friendly staff.

Blue Spruce is the most professional company I have ever come across!! On time, friendly and price effective. I definitely would recommend them to friends, family etc.!! :)

Thanks Adam for coming today!!

Adam was wonderful and explained all of my options and his suggestions after inspecting my heater. He and team were very communicative about timing and were able to come to my house quickly. Highly recommend!

My furnace went out this week and with sub zero temps only a few days away, Jeff was able to come look at it same day and determined that due to the age and the issues that it needed to be replaced. He was able to get me scheduled for a new furnace install the very next day. The techs Jeremy and Gavin were prompt and efficient, they had the old one out and the new one in and working with no issues in a half day.
