How to Know if Your HVAC is Overworked

Although they are built to last and are rugged equipment, it is possible that you have an overworked HVAC system. It could be nearing the end of its lifetime or being used in a way that makes it work harder than it needs to.

It runs in short cycles.

If your equipment runs for less than 7 minutes during a normal cycle, it is probably short cycling. The primary cause for short cycling is an oversized HVAC system. The equipment conditions your home too quickly and turns on and off often. The best way to avoid an oversized system is to insist on a load calculation before purchasing new HVAC equipment.

It has uninsulated or leaking ducts.

If you’re ductwork is not insulated or has leaks, your HVAC system has to work overtime to keep your home comfortable. HVAC contractors can either replace or insulate ducts and easily detect and seal air leaks.

Runs with a dirty air filter.

Neglecting to change the air filter causes an overworked HVAC system. The excess dust on the filter slows the air going through it and makes it work longer to cool or heat your home. Increased running time takes a toll on all the systems components. Clean filters are the most inexpensive and effective way to cut energy bills and increase the life of your equipment.

Doesn’t get annual servicing.

All HVAC systems need deep cleaning and adjusting periodically to run at their best. Neglecting professional maintenance will increase energy costs and shorten the equipment’s lifetime. Skipping the annual tune up may even void the warranty.

Is pasts its prime.

Your HVAC system is over 10 years old. Aging equipment has to work harder to keep your home comfortable. It may break down more often, develop strange noises, or not distribute the conditioned air evenly.

Having an overworked HVAC system might be symptomatic of deeper problems that are easy to solve. For more information, contact Arpi’s Industries, providing HVAC services for Calgary-area homeowners.
