Heating System Maintenance FAQs

You can always contact our team with questions about air conditioning tune-ups, repairs, or installations. Here are some questions our customers often ask!

Heating System Maintenance FAQs

Do I Need to Replace My HVAC Filters?

Yes, air filters must be periodically replaced in central and mini-split cooling systems. Ideally, this should be done every 3 months. Dirty air filters slow down airflow and reduce the efficiency of your equipment.

If your air conditioning is not performing properly, checking for a dirty air filter is a good place to start.

What Does a Furnace or Heat Pump Tune-Up Do?

Just like you take your car for an oil change, your home heating system needs some TLC too! If you live in the Central Valley, your furnace or heat pump is likely working for several months a year. Taking care of this equipment will extend the life of your unit and increase efficiency.

Tune-ups and heating maintenance are also a great way to prevent major repairs or damage from occurring. Our specialists get a chance to evaluate your home heating system and make recommendations for preventative measures that will save money down the road.

Why Can’t I Get the Right Temperature in My Home?

If your heating system is producing warm air but you can’t seem to get the desired temperature, it could mean your thermostat is faulty. Try adjusting the temperature up and see if your system reacts. The temperature sensor could be malfunctioning, in which case you’ll want to call an HVAC service tech.

Upgrading to a smart thermostat is one way to improve the efficiency of your heating system.

When Is the Best Time for Heating Maintenance?

You want your home to be prepared for the colder months, so schedule a furnace or heat pump tune-up before the winter starts. When a technician inspects your heating system, they ensure everything is working properly and ready for the cold seasons.

A service professional can suggest any repairs or upgrades to avoid heating emergencies when the cold is brisk. So think about scheduling your Heating Tune-Up in the summer or early fall.

“I called Cencal for my heater that wasn’t working back in Nov. 2021 and they fixed it right away. Now my AC wasn’t blowing cold air and I called Cencal. Cristian Ruiz came out and fixed it right away! He was responsive, professional, and knowledgeable! I’ve called other places before and they charged so much without even fixing the problem. I will be continuing to use Cencal for all my HVAC services. Thank you!”
