Critical Heating System Parts
Below, we’ve listed out many of our most requested part replacement services. Each component represents a critical part of your heating appliances. Should you have any questions, feel free to contact our team and ask about our heater parts replacement in Vacaville, CA.
Control & Electrical
HVAC Thermostat Repair & Replacement
Your thermostat ultimately controls the functionality of your HVAC system. A healthy system provides convenient comfort, but a malfunctioning system soaks up energy needlessly. If you’d like to learn more about your repair or replacement options, feel free to talk with one of our knowledgeable technicians!
HVAC Pressure Switch Replacement
Pressure switches act as safety checks inside your heating systems. If the system overheats, leaks gas, or otherwise breaks down, switches automatically turn off the appliance. Make sure your system isn’t shutting down due to faulty pressure switches!
Circuit Control Board Replacement
While some offer more advanced functions, circuit control boards primarily manage the gas and electric components of your heating appliances. They provide essential safety checks as well. A broken or short circuited control board will force your furnace to shut down.
HVAC Relay Replacement
Relays serve as safety and management devices to control the flow of electricity through your heating equipment. As with any electric component, you should never try to replace them yourself! Talk with one of our thoroughly trained and equipped technicians about replacement.
Combustion-Related Parts
Gas Valve Repair & Replacement
Did you know that natural gas, the substance that powers many furnaces and boilers, is actually toxic? That’s why the gas valve is such a crucial component of your system, safely admitting or blocking the flow of natural gas as needed to ensure a clean burn. Should this part break down, you’ll need to call for replacement as soon as possible!
Hot Surface Igniter Replacement
Depending on your furnace, hot surface igniters either light the gas burners directly, or they empower a pilot light to do so. If the igniter doesn’t turn on to start the burn of natural gas, safety switches will automatically shut down your heater. If your furnace is shutting down shortly after you turn it own, there’s a chance a faulty igniter or pilot light needs replacement.
Heat Exchanger Replacement
When your burners consume natural gas, the incredibly hot combustion gases make their way through a tiny little hole into the heat exchanger. This part might remind you of the evaporator coil by the AC blower. As gases flow through the coil, air from the blower flows over the exchanger and soaks up the heat. The newly warmed air then circulates around the house.
Motor Parts
HVAC Inducer Motor Replacement
This critical motor powers a fan that directs combustion gases into the heat exchanger so they can warm the air. Without a working assembly fan, your air won’t get warm enough before the blower circulates it through the ducts. If it seems like the furnace is only creating cool air, this could be the underlying problem.
ECM Motor Replacement
Rather than awkwardly switching from off to full blast, ECM motors enable your fan to slowly build power and save energy in the process. Our team at A 100% Guarantee Heating and AC would be happy to install or replace your ECM motor! To learn more, call 707-689-5128 and ask about our Vacaville, CA heater parts replacement.
Heater Capacitors Replacement
Two types of capacitors power your heater’s fan motor: a start capacitor and a run capacitor. As their names imply, the first enables that initial burst of electricity to start the fan, while the second allows it to continue running. Without working capacitors, the motor won’t receive sufficient current to activate.
Hard Start Kit Replacement
After long periods of inactivity, furnaces sometimes struggle to turn back on again. Hard start kits solve that problem by delivering a much needed jolt of energy to your heater. If your kit dies however, you’ll need to talk with a professional about your replacement options.
Specialized Heat Pump Repair & Replacement
Not every company has the parts, equipment, and experience needed to provide service for your energy efficient heat pump. At A 100% Guarantee Heating and AC however, our technicians provide all the expertise and heater parts replacement you’ll need to keep your system running for the long haul. To learn more about our heat pump services, call 707-689-5128.

Truly an outstanding company!
I had forgotten to have my HVAC system checked for a couple of years after our last repair. They reached out recently to check on how things were going, very friendly and no sales pitch! I realized how long it had been since I last spoke to them and I couldn’t believe how long their last repair held up on such an old system!
When I mentioned this, the office lady asked if we had been getting the annual maintenance done over the last few years. Since we had been putting it off over and over- i figured the best time would be now. I’m glad I don’t have that nagging at me randomly in the back of my head anymore.
The technician was professional and clearly knew what he was doing. After he finished he answered all my questions and updated us on the things that caught his eye.
I know the system will need to be replaced soon (it’s OLD!) but after he did the tune up, I’ve felt a huge difference in the house and he gave me some tips on how to keep it that way.
At least I won’t slack on having it serviced again since I pay monthly and they will be reaching out to me instead. I totally worth it!
