We’re all guilty of neglecting our HVAC system at some point, and who can blame us? It’s things like our heating and cooling systems that we take for granted until they break down on us in the dead of winter or during a mid-August heat wave. Though most AC units, furnaces, and other aspects of your residential HVAC system are reliable and well-made, regular maintenance is required to keep them working efficiently at all times.

At AKS Mechanical Services, our HVAC contractors have been serving local homeowners in the Richboro, PA area for years, so we know residential HVAC systems like the back of our hand. That being said, here are some of the most common signs that it’s time to have your home HVAC system serviced.

Abnormal Sounds & Smells

As with most other appliances in your home, some of the first signs of a residential heating and cooling system in need of repair are abnormal sounds and/or smells coming from your HVAC unit. Banging, clicking, grumbling, or squealing are all indicators of an HVAC system that might have loose or broken parts, usually involving the internal fan or a faulty compressor. Foul, egg-like smells, on the other hand, can be indicative of a natural gas leak, while musty smells could mean that you have mold growing in the ductwork of your HVAC system.

Hot Air Coming From Your AC Unit

Another clear sign that your HVAC system is past due for maintenance is that your AC unit blows hot air when you turn it on. This can be due to a range of factors, with most involving low refrigerant levels, a broken fan, or a malfunctioning compressor. Dirty air filters are another possible culprit, as they play a critical role in air flow. If your filters are clogged with dust or debris, this can prevent the air conditioner from properly circulating cool air through the ducts.

High Utility Bills

In many cases, residential heating and cooling systems won’t show noticeable signs that they are in need of maintenance or repair until you get your utility bills at the end of the month. If nothing about your energy usage has changed and your utility bills are through the roof, this could mean that your HVAC system has malfunctioned or is working harder than normal to keep your home at an ideal temperature. Unfortunately, this could also indicate the end of your home air conditioner or heater’s life, so be sure to consult your local HVAC contractor about the latest energy-efficient models when it comes time for an AC or furnace replacement.

Seasonal Changes

All things said and done, it’s wise to schedule regular HVAC maintenance when the seasons change — especially in the early spring and mid-fall. Prevention is key when it comes to HVAC repairs, and major changes in the seasons offer the perfect opportunity for an HVAC tune-up, as leaves, pollen, and other debris are at their peak. That being said, contact AKS Mechanical Services in Richboro if you are ready for a fall HVAC service! We look forward to making sure you have a warm, cozy home when rain and snow hit the East Coast in the coming months.
