Highly recommended service! Feb 26, 2025

We had a great experience with Comfort Energy. Big kudos to the company, to Jaime and Mike who helped us, they're really great! Highly recommended: 1) Very on time! Both inspection and installations, they come at the time they promised, and send messages to let us know that they're on the way. 2) They're detail oriented. They take quality very seriously, install the heater beautifully, handled all the small places (like we used to have water dripping outside and they helped us fix that). They're very professional and willing to spend time for good work. 3) Jaime and Mike helped us to install the Nest thermostat. Our wiring is very tricky, we thought we can't install Nest. Jaime and Mike explained different options, respected our opinion, and ended up with a simple solution to solve this issue perfectly. During the installation, Jaime compared the position very carefully to make sure it aligned perfectly on the wall. 4) They protect our floor whenever they're working, they organize all the wires and pipes beautifully, not just working but also working elegantly. Jaime installed the Nest for us, and vacuumed all the dust around the area after it was done. All the working areas were cleaned up carefully. 5) They take time to show us how it's working, how to operate, they have the right tools to diagnose and verify it's working properly. They're also very knowledgeable about this domain and willing to answer questions patiently. We're so happy with them, and really appreciate Jaime and Mike's great work. This literally made my day to have our heater fixed so confidently. Highly recommend them to anyone who needs similar service!

Highly recommend Comfort Energy Feb 16, 2025

Sharing my friend’s review that doesn’t have a Google Account: I just want to give a ‘shout out’ to ‘Comfort Energy’, who installed a A/C heat pump for me, on 7/11/2024. Kyle Allison, (sales), Beto Lopez, Craig, (office contact) and the actual installers, were all very professional, and their communications to me were excellent. My sales person, Kyle Alison, was extremely good to work with, clearly explained everything, answered all of my questions. Kyle also highlighted all of the potential energy-saving rebate programs that I could apply for, for purposes of getting cash rebates. The company, also on my behalf, applied for a cash rebate, which I did receive! On a specific date, the city was to do the permit inspection at my house. After I had waited at home several hours with Beto Lopez, I got an urgent call from my dentist’s office. They said that I needed to pick up my dental appliance right away before they closed their office for the long weekend. Beto immediately offered to stay and wait at my house for the city permit representative telling me that I could go ahead to my dentist’s office, and that he’d be waiting for me at my house upon my return. While I was gone, the permit person did arrive, and Comfort Energy’s installation passed inspection. I was incredibly grateful to Beto Lopez for his offer to wait at my house. Therefore, I highly recommend this company to anyone who is looking for someone to install an A/C/Heat pump.

Comfort Energy employees are friendly Jan 25, 2025

Comfort Energy employees are so friendly and helpful. Even though I resolved the cold, like A/C that was running, coming out of the velours, Stephan was checking out everything in the panel outside of the house, making sure all was OK. By me turning off the power button on the remote, and then waiting a good 10 before turning it back on, fixed the issue. We couldn’t figure out why one of the inside units was making a rattle sound. But, when I kept pressing pressure on the outside of the unit, it got slightly less noisy. Stephan took his time, trying to explain how the system runs. He was very respectful and kind. He took his time in explaining how the Mitsubishi works. I would definitely recommend Stephan, in helping you out.

Totally satisfied Dec 18, 2024

Stephan Reich provided a superb service experience. He was prompt, efficient, courteous, and very competent. He figured out the problem and fixed it quickly. He also explained our service options to maintain our mini-split systems. Totally satisfied.

Incredible service, I'm a huge fan. Dec 12, 2024

Comfort Energy installed a heat pump water heater for us, and it was the best interaction we've had with a contractor ever. I cannot rave enough - they were extremely responsive (answering the phone late at night, getting us in the next day when our previous water heater was leaking) the install was painless, and they managed all of the rebates and paperwork. Incredible service, I'm a huge fan. Thanks!

Installed with precision and care Nov 22, 2024

A Good Decision with Comfort Energy Sep 17, 2024

We replaced our heater with a more climate-efficient heat pump. After getting a few bids from local sources, we decided on Comfort Energy. It turned out to be a good decision. The people we worked with were extremely nice and very careful inside our house and out. Any issues we had were quickly taken care of. Best of all, we now have air conditioning added to our house along with heating.

David Braunstein

Efficient, Knowledgeable, and High-Level Performance Sep 5, 2024

Armando and Darwin did a great job of installing my heater and thermostat. They were efficient, knowledgeable, and performed at a high level. They helped me to understand the installation and how heating works in my home. They cleaned up well and sanitized the areas of my house that they touched. They seemed to take pride in their work and I would easily call on them again.

Impressive Knowledge and Professionalism Aug 26, 2024

Stephan R was our HVAC Service Technician today for Comfort Energy, 8/26/24. We were impressed with both his knowledge and professionalism, and the timeliness of his repair, which was under 30 mins. We would recommend Stephan and Comfort Energy for your HVAC needs.

Elizabeth Bosch

10/10 for the service provided Aug 21, 2024

I had trouble with my HVAC unit during the peak of summer, so I contacted Comfort Energy. The issue was diagnosed by their technician, Reuben, who suspected the problem was with the control board on the furnace. With my consent, he ordered the required part, which was later installed by technician Stephan. Both of these guys were super friendly and proficient in their work. They not only did a great job but also patiently answered all my questions and explained what they were doing. I highly recommend Comfort Energy for your HVAC needs. It’s a 10/10 from me for the service they provided.

Comfort Energy to the rescue! Jul 27, 2024

Once again - Comfort Energy to the rescue! I've used Comfort Energy a couple of times now and I'm very happy with this company. Thank you, Belsin! Thank you, everyone at Comfort Energy for the honest work and prompt response. My AC water condensate line was clogged. Initially, we thought a new line had to be installed. But, after Belsin's diligent troubleshooting, the line was cleared and extended properly. It's perfect and saved me a huge expense! Also, this, the AC stopped working on July 3rd, during the heatwave. After getting in touch with Comfort Energy on July 5th, Belsin came over on July 6th. We couldn't perform the repair right away, other contractor issue. But Belsin did not leave my family and pets without AC. He found a workaround, I can't express enough gratitude! Jan 24, 2023 Previous review Great company! Great management! Great staff! Troubleshooting can be very difficult, and you don't always get the expected outcome. Comfort Energy went above and beyond to restore heat when needed most and fix the furnace. Thank you!

Highly recommend Comfort Energy Jul 4, 2024

Belsin recently performed maintenance on my heat pump. He was thorough in his inspection and took the time to explain everything clearly. He even gave us helpful tips on how to maintain the air filter ourselves, which is something we never knew before. Thanks to Belsin's expertise, I feel confident that my heat pump is in good shape. I highly recommend Comfort Energy and Belsin's service!

Don't wait—reach out to them now! Jun 3, 2024

If you're considering HVAC services, I can't recommend Comfort Energy enough. I put off the mini-split AC installation for years, but decided that 2024 was the year I would stop sweating in my own house all summer! I was hesitant to go through the process because I was dreading the coordination with my HOA, but after my neighbors wholeheartedly recommended Comfort Energy, I decided to pull the trigger. Maurice was quick to provide everything I needed to get HOA approval and kept me informed of next steps along the way. I was absolutely delighted with the exceptional quality of work from Guillermo, our lead technician, and the level of service provided by Beto. From installation to city inspection, everything ran like clockwork. They were extremely professional, got the work done quickly, and were accommodating of my schedule, especially when I needed to take some work-from-home meetings during installation days. Don’t wait like I did—reach out to them now! I could have been enjoying a much more comfortable home for years.

Efficient and Personable Service May 9, 2024

When I called to schedule an AC tune-up, the appointment was scheduled very quickly, and Stephan, who came to perform the tune-up, was very efficient and personable.

Jocelyne Lew

I highly recommend them May 3, 2024

I have used this company for several years. Keeping my AC and furnace running in top condition is extremely important to me. Comfort Energy comes twice a year to make that happen. They are thorough, professional. They have done on-the-spot repairs when needed. I highly recommend them for all your AC and heating issues. And for regular maintenance.
