HVAC reviews in Concord, California

My air furnace had been acting up since last winter. I had called a different service company before to fix it. They said the system needed a new thermal switch for about $500 because my system was overheating. I didn't have them do the work because they gave me a hard sell and didn't seem honest. I called about half a dozen more places to schedule service and they all wanted over $100 just to come out and most just seemed indifferent. Then I called EHC. EHC's receptionist was very patient. She listened while I explained my situation, and actually connected me with one of their service technicians whose name was Noel. Noel was also patient and informative and had a free spot the next day. EHC does have a service call fee but it was only $80. Noel arrived on time and quickly and professional reviewed my HVAC setup and the furnace. After just a short time he told me that a new part might not be needed. Instead he could solve the source of the overheating by simply adjusting the burner settings!!!! This would solve the actual problem and not just "patch it" by replacing a part which just monitors the overheating. Can you believe it? An honest and competent answer! So far the system has been working fine, EHC and Noel saved me hundreds of dollars and seem to have solved the problem. I highly recommend them.

I’m very happy with the service I received from EHC Heating and Cooling. My furnace stopped working on a very cold day, and the technician did an excellent job of replacing a circuit board that died. He even came to my home 8:00 o’clock in the evening and stayed late to finish the job. Everything works properly now. I highly recommend them!

Eros is awesome!! I can’t say it enough. I hired another big box company who came out for 5 minutes and wanted to charge me for a bunch of stuff I didn’t need. Eros came, took time to diagnose the issue , find the leak, and come up with a solution that made sense. Within 48 hours my problem is fixed and I will be forever calling him!!!

EHC Heating & Cooling was a lifesaver for our family. We needed a same day heater repair and had a newborn baby in the house. They responded quickly, showed up on time, and fixed the issue fast. The technician was professional, kind, and understanding of how urgent the situation was. We’re beyond grateful for their care and excellent service. Highly recommend EHC Heating & Cooling!

I had such a great experience with EHC Heating and Cooling!!! I called them because it was the first time I turned on my heater in about a year, and it just wouldn’t turn on. I have a 4-month-old baby at home, so I needed it fixed quickly. They understood how urgent it was and came out right away.

The technician was extremely professional, friendly, and explained everything clearly. He found the issue fast and got the furnace running perfectly again. I was honestly so happy!! It’s hard to find companies that respond this quickly and care about their customers.

From start to finish, the whole experience was smooth, honest, and stress-free. I really appreciate how reliable and trustworthy they were, especially during a time when I needed heat for my baby. I’ll definitely be calling them again for any heating or cooling needs and highly recommend them to anyone looking for great service and peace of mind.

Eros at EHC Heating & Cooling was so supportive, professional and kind. I work for a large local church in a 100 year old building. Recently we have faced several setbacks with our furnaces and heaters, resulting in lack of heat this winter. This has been especially detrimental to the many senior citizens who meet in our space. I tried calling other HVAC companies for support, most of whom never even bothered to return my calls. When I reached out to EHC, Eros made a point of stopping by that very day and within 48 hours all three of our faulty furnaces were back up in working order! On top of that, two of the furnaces required a special replacement part which was difficult to find. He found a company in Fresno that had the parts but was unwilling to ship them. He drove all the way there and back from Oakland with the parts and literally saved the day for us. We have several elders using the rooms who will now have access to heat! We are so grateful to Eros and his team at EHC Heating and Cooling. We will definitely be contacting them again in the future!

We recently moved into a new home and discovered that the furnace wasn't working properly -- even when it was turned on, the house never warmed up. With winter approaching, we reached out to EHC for help.

Noel Rizo was assigned to our case, and he was absolutely fantastic. He arrived at our place within an hour or placing the service request. He was super communicative, arrived promptly, diagnosed the issue within an hour, and explained that the furnace needed to be replaced. He quickly followed up with a detailed report and scheduled a replacement appointment within the same week to ensure we'd have heat before the cold set in. He called us to confirm the appointment and even when he got the parts he needed!

Despite having a busy schedule and heavy traffic, Noel arrived exactly within the time window he promised. He worked diligently and efficiently, removing the old furnace and installing the new one with impressive attention to detail. He took great care to protect our floors, laying down tarps and ensuring nothing was scratched or damaged. When he was done, he left the area spotless.

We were thoroughly impressed by Noel's professionalism, craftsmanship, and work ethic. Thanks to him and EHC, our new furnace is running beautifully, and our home is warm and cozy ( We are actually excited about winter now! 😊 ). We couldn't be happier -- we highly recommend Noel Rizo from EHC for anyone in need of heating services.

David was amazing.
He showed up on the promised time window.
With a 10 minutes diagnostic he was able to pinpoint the issue. The circuit board went bad.
My lucky he had one with him.
Thanks to him the kids will sleep comfortably tonight.
Very professional, highly recommend.
