Had an issue where our AC was running but the house wasn't getting cool. Contra Costa Heating sent a tech who found that the ductwork in our attic had come apart at a joint. The cooled air was going right into the attic instead of the house. He resealed the ductwork and now every room is getting proper airflow. Good catch.

We had Contra Costa Heating install a completely new HVAC system in our home in Tracy. New furnace, new air conditioner, and new thermostat. The old system was original to the house from the 1990s and was struggling. The crew completed the installation in a day and cleaned up everything. The house is so much more comfortable now.

Contra Costa Heating replaced our old thermostat with a new programmable one during a tuneup and it's made a big difference in our comfort. Being able to set schedules and control the temperature from my phone is great. The tech set it all up for us and showed us how to use the app.

Had them do a fall tuneup on the furnace. Tech went through everything carefully, cleaned the flame sensor, tested the ignitor, checked gas pressure, and replaced the filter. He said the system was in good shape and should last several more years. Always feel better going into the cold months knowing the heater is serviced.

Needed a new furnace for our house in Hayward. Contra Costa Heating came out for a free estimate and the price was competitive with what we had gotten from other companies. They installed a new Rheem furnace and the difference from our old system is huge. The house heats up faster and more evenly. The crew cleaned up completely when they finished.

My AC unit was making a loud buzzing noise. Called Contra Costa Heating and they had a tech at our house in Pleasanton within a few hours. It was a faulty contactor. Fixed quickly and the AC has been running quietly ever since.

The service itself from the technician was very good. But the experience with Contra Costa was disappointing enough to share this rating. There was poor communication re: the appointment itself. Once schedule, there was no confirmation that day before or day of to let me know what time they were coming. However, their AI reached out to me the day before to schedule an appointment, when I confirmed I already had one it tried to cancel my existing one. After the service was complete, I paid the technician onsite and never received a receipt. I called and texted the morning after and received follow up from a live person and from the AI. Instead of a receipt for services they sent me a $0.00 balance due with no evidence of the details of service and what I paid for. (For context, this was over a $600 bill). I'm still waiting on a legal invoice for the $600 I paid detailing the service/parts I received. I don't recommend them.
