Jordan did a great job servicing my Mitsubishi HVAC system. He showed up on time and he was very thorough. He found a minor problem with the system that previous HVAC companies had not identified and fixed it.. It is difficult finding HVAC companies who are Mitsubishi diamond certified so I will be using them again in the future if my system has any problems.

Shawn was amazing! He helped install our new AC compressor last year and we had a moisture issue this year after the heavy rains and he came out same day and fixed the issue swiftly! Would highly recommend this company for their promptness and thoroughness!

I recently contacted Jordan with Eco Temp HVAC for a service call to troubleshoot an air handler issue, and I couldn't be more impressed. They responded incredibly quickly, which was a huge help given the situation Jordan was fantastic to work with. He was professional, knowledgeable, and genuinely cared about helping our mutual customer. He went above and beyond the scope of the original service call to make sure everything was taken care of properly. Excellent communication, prompt service, and outstanding customer care. I highly recommend Jordan and the Eco Temp HVAC team. Thanks again for the great service!

I hired another contractor who didn't finish the job properly.  I found Eco Temp online and spoke to Jordan who came out the same day.  Jordan was not only pleasant and professional; he was very knowledgeable on HVAC and knew right away how to resolve the issues.  It's difficult to find someone to work on fan coil units but Jordan was both pleasant and did great work and I would definitely recommend Eco Temp and will call them for future work.

We had an excellent experience with EcoTemp HVAC last Monday. Our boiler was malfunctioning, and they responded the same day we called. Jordan, our technician, went above and beyond by stopping on his way home to make sure we weren’t left without heat. He was extremely knowledgeable about Navien boilers, quickly identified the issue, and fixed it efficiently. Professional, courteous, and clearly well versed in his work. We truly appreciate the exceptional service and wouldn't hesitate to recommend them to anyone needing boiler service— especially Navien systems.

Five- star experience! From estimate to installation, they provided an excellent experience with our A/C replacement. The team was a true professional. It was an overall great experience. Everything went very smoothly. They truly overdelivered on all their promises and we would highly recommend them to anyone needing a new furnace and A/C. I would highly recommend it!

Thank you Eco Temp HVAC for installing my new thermostat and responding so quickly to my appointment needs. Their website made it very easy to schedule a timely appointment and I received text messages/reminders about it to fix my issue. If you're looking for someone reliable and skilled to handle your AC needs, I highly recommend Eco Temp HVAC!

We had a completely new unit installed. Eco Temp HVAC had a competitive price, and the price quoted was the price we paid. No change orders or hidden costs. Very fast and efficient (but careful) installation. They made me feel comfortable that they knew what they were doing and they weren't condescending about it at all. We will be returning to Eco Temp for all of our future servicing needs and will be recommending them to all of our friends and family.

Eco Temp HVAC installed a new HVAC system in our home recently and they did an excellent job. They were on time, and professional and they took the time to do the job right. Very, very, pleased with the service. I would recommend this company if you're looking to update your system or install a new HVAC system. Amazing job guys super happy with the work you provided.

Always great customer service. In our recent experience, the service was exceptional! The technician is awesome. Very patient, very friendly, and informative. He troubleshot and inspected the boiler until problem was found and repaired. Thanks for the old-school customer service and the kind employee who is trained and so helpful. It is highly appreciated.

Had a good few experiences with these guys over a few weeks time repairing boilers and also installing a new one. I found them to be very communicative  from appointment to arrival to completion and with providing options. Both front desk and staff were in ongoing communication. They did a good job with the installation and repairs and were honest with me about what needed to be done. I'm an out of state landlord and they kept me updated every step of the way. I recommend and I will use them again as I have to install a second boiler.

Great experience with Jordan and Eco Temp, I would highly recommend them! We were a brand new customer, but they came out very quickly, did a temporary fix so we had heat, and came back the next day with the new part. Friendly and professional service start to finish. We had originally called another company who said they couldn't get it started, it would take several days to get parts and fix, and there were multiple issues. We were suspicious, so we decided to call Eco Temp, and we are very glad we did!

Eco Temp was fast and prompt with their service! Jordan answered all my questions and didn't attempt to sell me anything extra. He was very professional and arrived about 5-10min early. I would definitely recommend this company to anyone!
