Benefits of Furnace Maintenance

Let’s discuss the benefits of furnace maintenance in more detail. Some of the benefits include:


Fewer System Repairs

A furnace that is running smoothly causes less wear and tear on moving parts and systems. That means you pay for fewer furnace repairs and extend the system’s life. In addition, that annual furnace maintenance call saves you a lot of money in furnace repair and replacement costs for your furnace.

Greater System Efficiency

When your furnace is operating at peak energy efficiency, it uses the least amount of gas or electricity to heat your home or business. Conversely, a furnace that struggles to heat your home or business uses more gas or electricity, which drives up the monthly cost of heating your space. An annual furnace tune-up will restore your system to peak efficiency which can make your home and wallet comfortable all winter long.

More Effective Heating

A tuned-up furnace will efficiently heat a home or business, making it easier for you to create the perfect ambient indoor temperature without turning up the thermostat. If you have rooms that are warmer or colder than others, during your routine maintenance, our HVAC technicians will be able to find the source of the problem to restore comfort to your entire house.

Eliminating Breakdowns

Tuning up a furnace means that each component works smoothly and produces the least possible wear on the system. That smooth operation also means that future breakdowns disappear, and you extend the unit’s life. A new HVAC system is a big investment, and furnace maintenance services help you get the most out of your investment by making your system last as long as possible.

How Often Should You Have a Furnace Tune-Up?

Most manufacturers recommend having furnace maintenance services performed once per year, preferably in the fall before you turn the system on for the first time. The exception to that rule is heat pumps, as they also cool your home in summer. Heat pumps that are used all year should be maintained and tuned every six months.

Welsch Heating & Cooling offers comprehensive HVAC services from trained heating and cooling specialists. We work fast, efficiently, and accurately to bring your furnace back to factory specifications.

Furnace Tune-Ups Save Time, Energy, and Money

When your furnace is not functioning correctly, it can create a dangerous situation within your home or business. Not only can a failing furnace produce excess CO2, but it can also often drive up your energy bills and do a poor job of heating your home or business.

A heating system that will not start creates a situation where you may not be able to use your home or business, especially during harsh winters. If you come home and do not have heat, it is an emergency. Welsch provides 24-7 emergency services to restore heat to your home. However, if you’ve had this happen to you before, you don’t want it to happen again, and that’s when maintenance service can help.

Furnace maintenance service is easy, and affordable, and restores your heating system to peak performance and energy efficiency. In addition, they are an easy way to prevent breakdowns, which can be costly. A tune-up for your furnace means that:

  • There are fewer furnace repair calls
  • You avoid higher energy bills
  • The lifespan of the unit is extended

P.S. I forgot to mention that Ed was our family repairman for a long time — I have good memories of him giving me broken parts to play with/disassemble when I was a kid!
