10 Things That Can Go Wrong With Your Furnace, Heat Pump

When anything seems wrong with your furnace or heat pump, the first things to check are:

  • Circuit breaker or fuses – make sure the unit has power
  • Thermostat – make sure you have it set to heat and the appropriate temperature
  • Reset – if your unit has a reset button, try that. If none of these work, give Isley’s a call.

Where is the noise coming from? Inside the house or outside? Noises usually indicate that something in your HVAC unit is going to break. Turn off the unit. Check the filter to see if it needs to be changed because clogged filters can cause your heating unit to make strange or unusual noises. If the filter is clean and your unit is still making strange noises, let us know.

If you’ve checked the circuit breaker or fuses and didn’t find the source of the problem, then it’s probably time to call for help. We don’t recommend that homeowners try to fix anything they can’t see; let us check the units and ductwork to find the source of the problem.

If your thermostat is turned on, and all circuits in your circuit breaker are OK, check the filter. When was the last time you changed it? Depending on how old your unit is and how much you use it, you should be changing air filters every 30 to 60 days. If everything checks out OK and your unit isn’t blowing air, it’s probably time to call a professional.

A number of things could be causing your utility bills to be high during the winter. The more your heat pump or furnace runs, the more it costs. If you’ve regularly changed your filter and ensured that no circuit breakers or fuses have gone bad, then you should call a professional. Isley’s TLC Maintenance Plan customers receive twice-yearly checkups, which can prevent some of these frustrating situations.

Your heat pump has a natural defrosting feature, but icing can still occur, even in Arizona’s mild climate. If your outdoor coils are blocked by ice, there could be a problem with the defrosting control. It could also be blocked by leaves or other debris or from water running on the unit. Isley’s maintenance plan includes an annual winter 40-point inspection and cleaning, which will help reduce the chances of this happening.

Check the circuit breaker or fuse box to make sure it’s not an electrical problem. Another common cause is a dirty air filter or a thermostat problem. If these are not the causes, give your home services professional a call. We often identify potential problems when we perform annual fall HVAC tune-ups for our customers.

Musty, burning odors the first time you run your furnace or heat pump are not unusual. If your unit has been idle for several months, especially after a busy haboob season in Arizona, you might have a lot of dust buildup. If after running the unit several times, the odor persists, turn the unit off and call a professional. We also recommend that all homes that have gas appliances install CO detectors.

When gas burns and it’s yellow, it’s not burning pure. You have a buildup of soot, which is probably because your pilot light is dirty. Your Isley’s technician can take it apart, clean it and reassemble it so the pilot light burns blue, as it should. If your pilot light keeps going out, it might be time to replace it. Most of today’s furnaces no longer use pilot lights, and many can be retrofitted with a spark ignition.

We hope you’ll consult a doctor first if you’ve got breathing problems or your family’s persistent sickness isn’t responding to conventional bedrest and liquids. If you’ve got gas-burning appliances in your house, you should install a CO detector, which will monitor your home’s air for carbon monoxide poisoning. Regular maintenance of your HVAC unit can also keep your family safe. Isley’s carries a number of solutions for cleaning your home’s air, which have been proved to reduce allergies and help people who suffer from asthma. See our Air Purification page.
