Would you drive your car without ever changing the oil? Probably not.

Just like your car, home heating systems such as furnaces, boilers, water heaters, heat pumps, and on-demand units require annual preventative maintenance to deliver the comfort and safety you deserve.

There are several reasons to have annual preventative maintenance performed by a licensed HVAC pro. For example, did you know yearly maintenance on your home heating system can reduce your energy bills by up to 30%? Or that 9 out of 10 HVAC systems fail due to a build-up of dirt and dust, or lack of maintenance?

Infographic on why homeowners need their home heating systems checked annually by a pro.


Benefits of Annual Preventative Maintenance

  • Increased Comfort – A clean system is a system that can deliver the comfort you deserve year after year.
  • Lower Energy Bills – Heating System Checks by professional HVAC companies ensure that your system is functioning as efficiently as possible.
  • Reliability – Avoid costly breakdowns when you need your system most: on the coldest nights of the year when it’s working the hardest.
  • Safety – A well-maintained system is far less likely to leak harmful gasses such as Carbon Monoxide (CO) into your home.
  • Warranty Protection – HVAC manufacturers recommend annual inspections and maintenance be performed by qualified technicians. Warranties can be voided if a lack of proper maintenance results in a problem with the system.


Increased Comfort


Clean, well-adjusted systems restore maximum heating capacity, resulting in warmer rooms that cost less to heat.

In forced-air systems, the build-up of bacteria, fungi, pollen, dirt, and dust can aggravate allergies, asthma, and emphysema because the contaminants can get into your indoor breathing air. In fact, indoor air is typically 3-5X dirtier than outdoor air according to the Environmental Protection Agency, which has labeled it a Top 5 Risk to Public Health. Yikes!



Lower Energy Bills


Even something as simple as a clogged air filter can reduce the efficiency of your system by 5-15%. It also puts unnecessary strain on your system by forcing it to work harder. As if that’s not enough, as little as .042 inches of dirt on a heating coil can reduce system efficiency by as much as 21%! Getting your heating system checked means your system is going to use less energy because it will run more efficiently. That’s good for your bank account and the environment.

This on-demand gas boiler we recently replaced had been compromised by a lack of maintenance, resulting in significantly shorter equipment lifespan. Annual heating system checks could have fixed this issue before it resulted in sudden (and costly) failure. Basically, the system was being forced to work much harder than it needed to because of the build-up of dust and dirt.

Safety is a significant concern, and an excellent reason to schedule annual preventative maintenance.


Just take a look at the compromised heat exchangers on these furnaces. Noxious gasses are created in the combustion process of home heating systems, and these leaks were allowing dangerous gasses such as Carbon Monoxide (CO) to leak into the home.

A bad heat exchanger is one of the biggest reasons why a furnace may be condemned. HVAC contractors are required to condemn furnaces with bad heat exchangers under New Hampshire state law. Basically, the expansion and contraction of heated metal can create cracks and holes in the heat exchanger over time, leading to potentially dangerous situations.

No one wants to hear that their furnace has been condemned and that they’re going to have to pay extra to have a heating system installation expedited. For example, weekend and after-hours charges can add up when you’re hurrying to get a new heating system installed before your water pipes freeze. Heating System Checks can avoid this scenario by telling you what you need before the crisis point is reached.

Warranty Protection


HVAC manufacturers recommend annual inspections and maintenance be performed by qualified technicians, and warranties can be voided if the lack of proper maintenance results in a problem with the system.
