We are so happy we selected Clarence with CAL Property Care to repair our furnace. He was very easy to schedule an appointment with and actually came out on a Saturday to figure out what the issue was. Clarence had to order a part to complete the repair, but he promptly updated us with the progress every step of the way. Clarence really went above and beyond and I can't say enough for his friendly attitude and quality of work! Thanks again Clarence!

Furnaces and thermostats are not mix-and-match appliances. Using the wrong type of thermostat with a furnace will cause operating problems and can be dangerous. Although thermostats look similar, they are designed very differently. There are numerous types of heating systems and thermostat systems and they need to be coordinated for safe and proper operation. There are three types of thermostat systems used today: millivoltage, low voltage, and line voltage.​

If those steps don't work, call a heating contractor. Despite the improved efficiency of most new furnaces, it's generally more cost-effective to repair a furnace than to replace it. However, if a key component such as the heat exchanger or control module fails, you're probably better off replacing the furnace, especially if the unit is more than about 15 years old. Furnaces typically last an average of 15 to 18 years.

Zach came early, which I very much appreciated, and got the job done quickly. He was unfailingly polite and took care with putting on the booties and keeping my carpet clean. He managed to get the sprinkler system turned off even though I was quite uninformed about it and could help very little beyond pointing to where things were. I am always happy to have Brothers people come out to do my plumbing, heating, & electric services.

Cleaning the debris that builds up on your filters will aid with the flow of air. When your air filter is clogged, your air handler must work harder to compensate for the blockage of air flow. In addition to driving up your utility bill, the reduced air flow through your heating and cooling system can cause your heat exchanger to overheat and shut off too quickly.
