Before You Call for HVAC Repair in Redlands, California

It’s easy to pick up the phone immediately when you suspect you need an HVAC repair in your Redlands or Loma Linda home. We want you to call when you need help. Let’s be sure, however, an HVAC repair is necessary.

Check These Before You Call for HVAC Repair

HVAC Air Filter

It’s easy to forget about changing the filter, we know. The air filter, however, is an important component of your heating and cooling system. All air circulating in your home passes through this filter as it moves throughout the ductwork and your furnace or heat pump.

The filter catches the majority of dust, debris, pollen, pet hair, dander and other indoor pollutants in your indoor air as it passes through the HVAC system. If the air filter becomes clogged, it can’t do its job well.

Furthermore, when the air filter is clogged, the heating and cooling system strains itself to push air through it. This extra wear and tear on your furnace, heat pump or air conditioner may shorten its lifespan and is more likely to require HVAC repair.

It may even need replacement earlier than it should. Avoid this premature expense with a simple check of your air filter every month and change it when it becomes dirty.

Most air filters require changing every two to three months. If your furnace shuts off and refuses to come on, it’s possible the air filter is dirty. When the furnace struggles to push air through the system, it often causes the furnace’s heat exchanger to overheat.

As a safety precaution, the furnace’s “limit switch” turns the furnace off. A fresh air filter may allow your furnace to resume normal operation. If a clean air filter doesn’t solve the problem, it might warrant a service call. There are a few other things you can check first.


Your thermostat relays orders to your heating and cooling system, based on the ambient temperature. The thermostat calls the shots and if it malfunctions, your furnace or heat pump is without its leader.

Therefore, if your furnace, heat pump or air conditioner won’t perform, confirm the thermostat is on. Sometimes unrelated activities like dusting or kids’ horseplay knocks the button or lever just enough to turn it off.

Review the display and verify the settings and information are correct. If it doesn’t reflect what you know to be true, it’s likely to be compromised.

Pilot Light

Some gas furnaces still use a standing pilot light. Newer models have a slightly different mechanism. If your system falls into the former category, check to see if the standing pilot light is lit.

When out, the HVAC system won’t start the burner assembly to generate heat. If you feel uncomfortable relighting the pilot light yourself, give us a call and one of our technicians can service your system. If you do light it, though, and it refuses to stay lit, you need a professional to inspect it.
