Take Care of Your Family First
What to Do When the Furnace Stops Working:
- If your carbon monoxide detector goes off, call 911 immediately.
- Move family members (especially children, elderly parents and family members, and pets) to a warm and safe location.
- Stay warm. Use portable space heaters, heating pads, and blankets, and/or turn on the fireplace as you wait for service.
- Resolve your furnace problems by calling a trusted professional.
What to Do When the AC Stops Working:
Move to a cool, safe space (especially children, elderly parents and family members, and pets). In Arizona, a broken AC unit can be the cause of heat stroke or other heat-related illnesses.
- Cover windows, turn on a fan, and/or plug in a portable AC unit for the duration your AC is out.
- Keep your family hydrated.
- Resolve your AC problems by calling a trusted professional.
Common Heating and Furnace Problems
Heat Pump Is Tripping the Breaker
If your heat pump is tripping the breaker, it could signal any number of issues that should be addressed right away by a heating expert. A heating technician can take care of mild furnace problems, such as a dirty air filter, but you can save time and money by learning how to clean or replace this filter on your own.
Furnace Keeps Running
Why does your furnace keep running? To catch up with the fridge, of course! All kidding aside, furnaces should only run when they’re increasing the temperature in your home. If it runs indefinitely, it will create risks in the home—and increase your utility bills. Some furnaces are meant to turn off in cycles, but if yours doesn’t, there are a few things to try to get it to run correctly.
Bad Smells Linger Around Furnace
Do you smell something burning by the furnace—like the scent of burning tires or plastic? If you’ve noticed the bad smell for a while and it doesn’t go away with a simple filter change, there might be a serious furnace problem or electrical equipment issue you’re facing. Visual signs that accompany this problem include smoke coming out of your grills or registers.
Furnace Blows Cold Air
A furnace that serves cold air rather than warm air sounds like a major heating problem, but it’s actually caused by one of many minor problems that don’t require demanding repair work. It all comes down to finding where the issue lies—which could come from under the hood to inside the vents. A Patrick Riley HVAC pro doesn’t need much time to diagnose the source of cold air and take care of the problem.
Common Cooling & AC Problems
AC is Making Loud, Strange Noises
An AC unit that makes loud buzzing sound or other unusual noises is a cause for concern, and we recommend turning the system off until a professional can look at it. Problems from the electrical setup to the AC’s evaporator coils could cause damage to the unit if it continues to run. If you hear a noise, the problem is likely just as bad as it sounds.
Weak Airflow Coming From Vents
If you don’t feel a strong breeze from your AC like you remember, something might be wrong in your ventilation and causing the air to escape prematurely before it can reach your grills. Another possibility is a surprising phenomenon that happens from inside the AC that keeps air from cooling altogether.
AC is Blowing Mist
Mist coming out of an AC system sounds unusual to many homeowners, but it’s nothing that we at Patrick Riley Cooling, Heating, & Plumbing haven’t dealt with before. Some ACs can still run well when they’re spraying short bursts of mist now and then, but an AC blowing mist for hours or accompanied by a musty smell is a cause for concern.
AC is Short Cycling
When an AC short cycles, that means the system shuts itself off sooner than it’s supposed to. This can lead to lengthy periods of heat and humidity in certain rooms—despite having an AC unit that works.
You or a Family Member Experiences Allergic Reactions
It’s not normal to suddenly experience allergies inside the home, and it may have to do with your AC system. Your air conditioner might be getting dirty or old, which is one way contaminants get into your home’s air. Allergies can also occur while dusting if you have your thermostat set to a specific setting. Knowing what you can do for your system can alleviate allergy problems in Arizona.
