Heating Tune-Up & Maintenance

Why Do I Need a Heating Tune-Up?‚Äč

Getting yearly heating tune-ups is important because it can help minimize the potential for larger, and more costly, issues to develop. Additionally, routine inspections help ensure that your unit is operating safely and efficiently. At Guaranteed Service, we have experience working with multiple types of units and assure you that we will keep yours performing at its best.

The Benefits of Heating Tune-Ups

  • It will ensure proper airflow: We check your heating system to ensure there is no restricted or limited airflow, which places an unnecessary strain on your heating unit that can lead to increased repairs and a shortened lifespan.
  • It will keep you safe: Heating units burn fuel to produce heat. The combustion process must be precise to maintain efficiency and safety. Even a small problem can lead to gas leaking into your home or dangerous carbon monoxide levels. Don't take a chance with the health and safety of your family.
  • It will reduce repairs: Every winter, we receive calls with heating problems that could have been easily prevented with regular maintenance. A tune-up not only includes cleaning that keeps your unit running efficiently, but it also catches small problems before they turn into major repairs.
  • It will save time: Getting a tune-up before the weather is too cold is much more convenient and cost-friendly than waiting for a repairman during the winter in a freezing home without heat.
  • It will improve energy efficiency: A tune up includes a cleaning and inspection of the unit heat exchanger. In addition to ensuring safe operation, this will keep your unit running efficiently all winter.
  • It will maintain the manufacturer's warranty: If your heater is under a manufacturer's warranty, it is especially important for you to get an annual heating unit tune-up. Most manufacturers stipulate that their warranty becomes void if the heater is not regularly maintained. A tune-up can satisfy this requirement so you can maintain the warranty.

Professional & Friendly
Truly great service! He was professional & friendly. He is clearly experienced because he installed a water-pressure sub pump backup system for us which is a complicated job. He came back again a couple of days later to replace an old leaking toilet. He was considerate with cleaning up afterwards too. I highly recommend Guaranteed Services & especially Rob.
