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!

Customer would like to have her furnace maintained before winter. She would also like her blower wheel and assembly cleaned. System was operational upon arrival. I checked the components within the unit and found the blower capacitor was out of specifications. It was replaced with new one. Blower assembly was pretty dirty. I cleaned the assembly. Burner assembly was ok, I cleaned flame rod. CO output was nominal. Heat output was also nominal. No other issues at this time.

An annual inspection of your unit can ensure that the various potential problems mentioned above are detected early, and before they require complete replacement. During this inspection, for instance, a professional might find small cracks in your heat exchanger or a faulty seal in your blower motor. Some manufacturer's warranties even require these annual inspections to maintain validity. Typically, your furnace inspection will cost between $80 and $150 depending on the area in which you live and the professional you work with.
If your home is not heated using forced air, chances are a boiler will make sure you stay warm during cold nights. A hot water system delivers hot water through a network of pipes that run to every room in your house. The heating effect gets maximized through radiators. The most common issues with hot water heating tend to be not be major, but small problems that add up over time. Mineral deposits within the water tank, a pilot light malfunction, or an issue with a radiator itself can require professional repair. On average, you will pay between $183 and $582 for these problems. The exact amount will depend on the exact problem, as described in our boiler repair cost guide.

There’s a common misconception that you can save money by shutting the vents (supply registers) in rooms that aren’t being utilized. Resist the urge to close too many, as doing so can actually increase the pressure in your furnace, making it work harder to heat your home. This can lead to failed blower motors, mold or mildew in your ductwork, damage to the compressor, a cracked heat exchanger, and other problems. What Does a Furnace Tune-Up Include?
Don has earned a lifetime customer! My wife and I moved into our fixer-upper house this summer and just when the weather turned we realized that the 8 year old Goodman furnace in our basement had rusted heat exchange pipes and was leaking carbon monoxide. (So much for the $400 I paid to an home inspector before we moved in...) Fortunately, the furnace had a warranty still active. Not so fortunately, Goodman was incompetent in getting us the replacement part. It took them a month to send it, and then it wasn't even the right part. Don went to bat for us and convinced Goodman to foot the bill for an entirely new furnace! He and another worker made time in their busy schedule during thanksgiving week to come out and get the unit installed. This is above and beyond service and I couldn't be happier.
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.​
