Furnace Maintenance


MAXIMIZE Efficiency

At Harker Heating and Cooling Inc., we understand the importance of keeping your furnace operating at its best. Most furnaces start at 90%+ efficiency, but their efficiency dwindles over time. As time goes by, furnace systems efficiency can decrease to 70% or less, meaning a substantial 30% or more of the gas you purchase isn’t heating your home. Our certified HVAC technicians specialize in optimizing your furnace’s performance to ensure you get the most out of your heating system.

EXTEND Longevity

Furnaces that receive proper care tend to have longer lifespans compared to those left unattended in the basement. When neglected, minor issues can quickly escalate into expensive repairs or the need for a costly replacement. Don’t let a malfunctioning furnace surprise you on a frigid January night. Instead, safeguard your investment by scheduling regular furnace maintenance with Harker’s certified HVAC technicians.


If your furnace hasn’t been maintained, you and your family could be at risk of carbon monoxide (CO) exposure. Carbon monoxide is an invisible, odorless and tasteless gas produced during the combustion of natural gas, and prolonged exposure can result in carbon monoxide poisoning. A properly functioning furnace vents CO safely through the side of your home or your chimney, but a compromised system can potentially release it into your home. Gain peace of mind with heating services and furnace maintenance by Harker.


Think of your furnace like a car- new, well-maintained cars have high fuel mileage rates while poorly-maintained cars emit black smoke and are stinky to drive behind. Just like a car, your furnace has an exhaust system that requires regular cleaning and inspection. Neglected systems can emit unnecessary greenhouse gasses and consume more gas than necessary to generate the same amount of heat. Let Harker help you achieve both a greener home and cost savings.

Schedule your furnace maintenance today and make a positive impact on your home's efficiency, longevity, safety and the environment.
