"They showed up one day earlier than the original appoint whic was great! The technician wore the N95 mask I provided. Work was done quickly and thanks to them I was only out of air conditioning for 24 hours. Very happy. Price was reasonable and I set up a maintenance schedule with them."

"Called J&J after our first service person flaked. Wish I had called them first. Howard B was very professional and explained what our issue was in terms we would understand. From first call to completion was about an hour and a half. Super quick! Even on a Sunday, their pricing was more than reasonable! Will definitely continue to use them!"

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.

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.
