I have nothing but the highest praise for Juan. He was diligent, knowledgeable, friendly, polite, shared some great info. I had initially hired Airstars to just replace a thermostat in an old oven but ended up purchasing a completely new one. No regrets. They made it painless. Will 100% hire them again for whatever appliance needs.

6 SIGNS YOUR HEATER NEEDS PROFESSIONAL REPAIR
Ignoring a furnace problem can be dangerous. Gas furnaces produce Carbon Monoxide (CO), and a malfunction can put your family at risk. According to the CDC (Centers for Disease Control), regular heating maintenance is the #1 way to prevent accidental CO exposure in the home.
Call us immediately if you notice:
1. Blowing Cold Air
If your furnace is running but the air coming out of the vents is cool, you may have a dirty flame sensor, a pilot light issue, or a problem with the gas supply.
2. Loud or Unusual Noises
- Banging/Booming: A dangerous ignition delay. The gas builds up before lighting, causing a small explosion. Call us immediately.
- Squealing: A slipped belt or dry motor bearing.
- Rattling: Loose panels or a cracked heat exchanger.
3. Yellow Pilot Light
A healthy furnace flame should be blue. A yellow or flickering flame often indicates incomplete combustion, which can lead to a carbon monoxide leak.
4. Frequent Cycling (Short-Cycling)
If your heater turns on and off every few minutes, it is overworking. This is often caused by a clogged air filter or an overheating safety switch tripping the system.
5. Weak Airflow
If you can barely feel the heat coming from your registers, your blower motor may be failing, or your ductwork may be disconnected.
6. High Energy Bills
If your PG&E bill has spiked without a change in usage, your furnace is losing efficiency. This often happens when internal parts wear out and the system has to run longer to reach your set temperature.

HEATING REPAIR FAQS
How much does furnace repair cost in Hayward?
Repair costs depend on the part needed. A simple flame sensor cleaning or capacitor replacement is inexpensive, while a blower motor or control board replacement costs more.
Is a cracked heat exchanger dangerous?
Yes, extremely. The heat exchanger separates the breathing air from the combustion gases. If it cracks, carbon monoxide can leak into your home. If we find a crack, we are required by law to shut down the unit for your safety.+1
How often should I service my furnace?
We recommend a yearly heating tune-up in the fall. Regular maintenance ensures your warranty stays valid and prevents breakdowns during the coldest nights of the year.
Do you fix floor furnaces and wall heaters?
Yes! Many older homes in San Leandro, Castro Valley, and Oakland still use these units. We are one of the few local companies with the expertise to service and repair them safely..
Should I repair or replace my furnace?
We look at the age of the furnace, the condition of the heat exchanger and burners, and how often it has needed repair. If a repair makes sense we say so; if replacement is the better choice we explain why before quoting.
Do you install heat pumps as well as furnaces?
Yes. We install and repair gas furnaces, heat pumps, dual-fuel systems, wall heaters and floor furnaces, and we can talk through which suits the house and the existing ductwork.
