What Does Heater Maintenance Involve?

Exact heater maintenance will depend on the specific model of your furnace and its overall condition. However, the typical heater maintenance checklist will include:

Checking gas lines

Inspecting heat exchanges

Calibrating and testing burners

Inspecting electrical connections

Cleaning drain clogs

Replacing furnace filters

Testing safety controls

Calibrating thermostats

Replacing motor belts

Lubricating parts

In addition to cleaning, heater technicians will test your system to make sure it's operating in the right parameters. If they detect a problem, they can repair it on-site or schedule another appointment for repairs or maintenance. If need be, our knowledgeable staff can help you choose options for furnace replacement.


Our team of heater technicians has experience working with all kinds of heating systems, including furnaces, water heaters, heat pumps, and more. Moreover, we strive to make the heater maintenance process as hassle-free for our clients as possible.

Benefits of Regular Heater Maintenance

Like any other part of your heating and cooling system, regular heater maintenance has some noteworthy benefits.

Extend Lifespan

The typical furnace can last upwards of 20 years properly cared for. Regular maintenance can extend your furnace’s lifespan by at least five years. If your furnace is getting up there in the years, you may want to consider getting a furnace replacement.

Reduce Energy Bills

A worn-down furnace does not burn efficiently, which can increase your gas or electricity bills. Clogged furnaces have to work harder to produce the same heating, and the result is your furnace works harder to get the same outcome. If you notice your energy bills spike from previous months, it could be a service issue with your furnace.

Less Frequent Repairs

Regular heater maintenance can also save you a sizable amount in future repair costs. If you neglect maintenance, your unit is more likely to break down, meaning more frequent and expensive repair costs. Sticking to a servicing schedule makes a breakdown much less likely.


A good general rule is if the cost of repairing your furnace is more than half the cost of installing a new unit, replacement is the better option from a financial standpoint.

Less Frequent Repairs

Failing to get regular maintenance means your machine is much more likely to break down, and frequent breakdowns mean you have to spend much more on AC repair costs. A good rule of thumb is that if AC repairs cost more than 50% of the cost of installing a new machine, replacement is the better option.


Even if you take great care of your machine, you will probably still experience a breakdown at some point. But If you remember to get regular maintenance, repairs will be much less frequent and less expensive.

Better Indoor Air Quality

A worn-down gas furnace can actually be dangerous for you and your family’s health. If your furnace does not get enough airflow, it won’t complete the combustion reaction with gas. Incomplete combustion can produce carbon monoxide, an odorless and colorless gas that can be dangerous if inhaled.


A yellow pilot light on a gas furnace means it is not getting hot enough to burn the gas completely. If you suspect your furnace is leaking carbon monoxide, it’s imperative to call a professional immediately.

Heater Maintenance FAQs

  • Do Heaters Need Maintenance?

    Yes. Just like any other part of your heating and cooling system, heaters require maintenance. Neglecting regular heating system maintenance negatively affects system performance and can contribute to higher energy bills. Forgoing maintenance can also shorten your system’s lifespan.

  • How Do I Check My Heating System?

    You can check your heating system by adjusting the temperature and noting performance. You can also visually inspect things like filters and components for obvious signs of clogging and dust. Modern heating systems may spit out an error code on the control panel if it detects something is wrong.

  • How Often Should I Service My Heating System?

    We recommend having a professional service your heating system at least once per year. If you live somewhere that sees frequent moisture or dryness, you should get servicing at least twice a year, once every six months. You may require more frequent maintenance depending on average usage.
