Five Signs Your HVAC System Needs CPR

Your System Can’t Keep Up
If your furnace or boiler is constantly running but not keeping your home comfortable, it’s having efficiency issues. Let our Lisle HVAC professionals take a look.
Excessive Moisture Around Your Furnace
Pooled water, condensation where it shouldn’t be and or visible rust are all signs of a system problem. furnace and boiler systems should stay dry during operation.
Excessive Dust in Your Home
If you’re constantly dusting or notice allergy symptoms getting worse, your HVAC system might be to blame. First, check your filters. If this isn’t the problem, you might need furnace maintenance or ductwork service.
Strange Smells from Your HVAC Equipment
A musty, burning, or chemical smell emanating from your vents or equipment indicates a problem. It’s a sign of things like mold growth, wiring issues, or refrigerant leaks. This issue is often a safety risk.
Your System Keeps Tripping the Breaker
Is your furnace or boiler flipping your breaker? Then, it’s likely drawing more power than it should or has some sort of electrical problem. This can be caused by overheating parts, failing motors, or wiring problems.
