The Telltale Signs You Need Heating and AC Repair

Heating, Air Conditioning, and Ventilation (HVAC for short) equipment sometimes stop working without warning. But often, they will give you plenty of warning that something is wrong.

Warning Signs To Take Seriously Include:

Sounds and Odors

Your ears and nose can tell you if HVAC repairs are needed. A high-pitched whistling can indicate a duct blockage or clogged filter. Rattling often means some type of hardware is damaged, while the sound of clanging metal often means fan blades are broken. If you hear buzzing or humming, the fan motor or capacitor could be failing. A musty odor can mean there’s mold, but an electrical smell can indicate faulty wiring or parts.

Colds and Allergies

Evidence for adverse health effects of air pollution in our homes has grown dramatically. Low air quality in our homes – air with dust, pollen, viruses, germs, mold, pet odors, bad smells, VOCs, and many other particles circulating throughout, can contribute to a broad array of chronic health effects.

Restricted Airflow

If less air is blowing from your air conditioner, it may have a clogged filter, or there could be a blockage in the ductwork. A motor, fan, or compressor problem can cause inadequate airflow as well. You can check for clogged filters, blocked vents, for other issues such as dirty coils. You can also have a technician check for low refrigerant levels.

Hot Air When The AC Is On…

It’s never normal for hot air to blow from your air conditioner vents. It can mean the refrigerant is leaking somewhere or that the compressor has failed.

And Cold Air When The Heater Is On

Your furnace may be blowing cold air because the filter is too dirty. A dirty air filter blocks airflow over the furnace’s heat exchanger, causing it to overheat. When overheating, your furnace can trip a high limit switch, causing the furnace burners to shut off. A good HVAC specialist will fix this in no time.


Air conditioners can produce condensation. But there shouldn’t be enough to cause water to leak into your home. Likewise, indoor humidity should be regulated by your air conditioner; if it is not, repairs are needed. If you notice an active leak or water pooled up near your A/C, there can be significant damage if a technician doesn’t repair it. And call a professional immediately if you notice a coolant leak—this can be extremely dangerous.
