Is a Maintenance Agreement That Important?

The answer is yes! Regular HVAC maintenance is extremely important. Preventative maintenance is intended to keep your heating and cooling system running all year long with no surprises that can be costly and unexpected. Another reason to have your system tuned up is to make sure it’s running at a high level of efficiency. What would happen to your car if you never had the oil changed or took it into a shop for a tune-up? The same is true for your home’s comfort system. No matter how good or expensive your equipment is, regular maintenance is a necessity. Annual maintenance is essential to both your heating and cooling system.

What Can You Expect from Your Tuned-Up HVAC System?

Some benefits of regular maintenance are immediate, while others help future problems from developing. However, the question you should ask is, “Is the cost of maintenance worth it?”

Here are some of the benefits of keeping your system tuned up:
  • Fewer repairs: Having a trained professional examine your system regularly will help you find potential problems like a clogged coil, dirty filter, or leaks that if left unchecked can result in expensive repair bills.
  • Family safety: If your furnace develops a crack in the heat exchanger, carbon monoxide gas can escape and poison the air you breathe. An electric short circuit can cause a serious fire hazard if ignored. Your family’s safety is one of the best reasons to have regular HVAC maintenance completed.
  • Longer equipment life: One malfunctioning part on your furnace or air conditioner can lead to a domino effect down the road. The changes of this happening are less likely when you have a professional technician performing regular maintenance each season. Regular maintenance can add years to the life span of your equipment.
