    The Best Frederick Furnace Tune-Ups

    Frederick customers should know that heating and furnace maintenance is important for several reasons. It protects manufacturers’ warranties, lowers utility bills, allows for more energy-efficient heating, and even has a positive impact on the environment.

    Let us introduce you to our Comfort Club. This is the program that you’ll sign up for, and it gives you the choice between an annual or biannual tune-up. The agreement endures for 12 months, after which you can choose to renew it or not.

    As part of our visits, we can:
    • Inspect the blower compartment
    • Tighten loose electrical wiring
    • Check the blower motor, wheel, and belt
    • Check the ambient temperature
    • Check suction and liquid line temperatures

    Many of these tasks go a long way to keeping you safe. After all, loose wiring is a fire hazard. Drain lines, if they’re not blown clear by our team, can lead to flooding. We’ll calibrate your thermostat so that it accurately reads indoor temperatures. Air filter replacement is another part of our furnace tune-ups here in Frederick.

    Every technician underwent a background check and is subject to random drug testing, so you can feel confident in inviting them into your home. This is just one part of what we call our Peace of Mind Guarantee. Frederick residents can expect the technicians to use floor savers and clean up after furnace maintenance. They will be courteous at all times, never smoking or swearing.
