Answers to Common Furnace Problems

Furnace problems are common, and that shouldn’t be a surprise. You use your heating or cooling almost daily, and eventually, those systems will wear out and break down. Luckily skilled technicians can offer furnace repair in San Jose, CA. What are some of the most common problems?

Furnace Blowing Dirty Air

This is actually a pretty common problem. Dirty air comes from the buildup of particles and bacteria in the system. An HVAC technician can use precision tools to clean the sensitive and hard to reach areas of your furnace. They can clean any microbiological growth around evaporator coils, pans, and condensate lines. They can clean sticky or greasy buildup around the fire exchanger, gas lines, and gas valves. They can also clean up any organic yard waste around the air ducts, return ducts, and the condenser unit.

High Utility Bills

If your utility bills get uncommonly high, a good place to start troubleshooting is with the furnace. A few things to have a technician check would be airflow, pressure, gas, and heat expenditure. They might find gaps in the ductwork or malfunctioning motors and fans. Or it could be an issue with the thermostat. With a few repairs, a technician should be able to get to the root of the problem. That said, with older furnaces the high cost can’t be helped.

No Heat

Do you feel like your furnace isn’t blowing enough heat, or is even blowing cool air? Before you call an HVAC technician check the thermostat to make sure the settings are still correct. Next double check to make sure all of the vents are open and uncovered. Third, confirm that both electricity and gas are available. If you troubleshoot these issues and still your furnace isn’t blowing warm air then it is time to contact a professional. They can check to see if your furnace can hold a flame or ensure the blowers are working as they should push air through the system. Up to 75% of no heat issues are caused by buildup from a lack of maintenance.

Pilot Light Problems

Another common problem is a faulty pilot light or ignition system. The furnace needs these to ignite the burners. The problem could be drafts or clogs. Or you might not be getting enough gas to the system. These types of issues are best left to the professionals.

Frequent Cycling

Does the furnace keep kicking on and off? This often stems from a clogged filter. The system has to work extra hard to draw and push air through the ducts which can cause overheating and trips a safety shutoff. But if you check the filters and they seem fine it could also be poor airflow or a faulty thermostat.

These are just a few of the common problems that might require furnace repair in San Jose, CA. If you are having issues with your furnace there are a few things you can safely troubleshoot.
