How Often Should My Air Conditioner Be Inspected?

It is not uncommon for homeowners to forget about regular AC inspections. In order for your air conditioner to last for as long as possible, it needs to be inspected, cleaned, and serviced at least once a year. We recommend having your system looked at in the early spring to prevent summertime breakdowns.

Benefits of regular inspections include:
  • Extended equipment lifespan
  • Money savings
  • Increased energy efficiency
  • Improved comfort
  • Better indoor air quality
  • Fewer system breakdowns

To keep your system in top shape, schedule annual inspections with our Marlboro air conditioning and heating professionals. We are committed to making sure our customers are safe and comfortable in their homes, and preventative maintenance is the best way to achieve that.

Why Is My Heater Blowing Cold Air?

Nothing is worse than coming home on a cold day, turning on your heater, and being blasted with more cold air. While a cold heater is incredibly frustrating, it is not cause for panic. There are several easily fixable reasons why your heater might not be working properly.

Your furnace could be blowing cold air because:

  • The fan is set to “on” instead of “auto”
  • The pilot light is out
  • The air filter is dirty and clogged
  • The ductwork is leaking
  • The flame sensor is dirty

To know for sure what is preventing your heater from doing its job correctly, you need an expert on the job. Our professionals are backed by extensive experience and are available 24/7 to get your heater back up and running.

We Fix It Right the First Time, Every Time!

Complete customer satisfaction is our ultimate goal and in order to provide the best experience possible, we are committed to resolving your problems right away. From furnace to air conditioner to indoor air quality to plumbing to water heater systems, our highly trained, fully certified technicians can manage any repair, installation, and maintenance service you might need.
