FAQs
What kinds of heating equipment do your certified technicians repair in Gruetli-Laager?
Our team services virtually every residential and light-commercial heating system found in Grundy County, including gas furnaces, electric furnaces, heat pumps, dual-fuel hybrids, packaged rooftop units, and ductless mini-splits. We are trained on all major brands sold in Tennessee—such as Trane, Carrier, Lennox, Rheem, Goodman, and York—and we follow the latest ACCA and EPA guidelines to keep your manufacturer warranty intact.
Are your technicians really certified and insured?
Yes. Every technician who enters your home holds current EPA Section 608 refrigerant certification, NATE (North American Technician Excellence) credentials, and is factory-authorized on at least two major equipment brands. In addition, our company maintains Tennessee mechanical contractor licensing, $1 million in liability coverage, and full workers’ compensation insurance, so you are completely protected during any repair visit.
How fast can you get my heat back on during an emergency?
Because Gruetli-Laager winters can drop below freezing, we offer true 24/7 emergency dispatch—even on weekends and holidays. Calls received before 10 p.m. are usually answered within 2 hours, while overnight calls are handled first thing in the morning. Our service vehicles are stocked with the most common furnace and heat-pump parts, allowing us to resolve about 85 % of no-heat cases in a single trip.
What does a typical heat repair cost, and do you provide upfront pricing?
After a diagnostic check ($89 flat rate), your technician will explain the root cause, present all viable repair options, and quote a firm, itemized price from our standardized price book before any work begins. Minor fixes—such as flame sensor cleaning or capacitor replacement—generally run $120-$250. Major component swaps like blower motors or heat exchangers can range from $400 to $1,200. You’ll never face hidden fees, and we waive the diagnostic charge if you approve the repair on the spot.
Do your repairs come with a warranty or satisfaction guarantee?
Absolutely. All replacement parts carry a manufacturer warranty of at least one year, and our labor is guaranteed for 90 days on minor repairs and one full heating season on major component replacements. If the same problem recurs within the covered period, we’ll return at no charge to make it right.
How can I prevent future heating breakdowns and lower my energy bills?
The best defense is proactive maintenance. We offer a bi-annual Comfort Club plan that includes a 21-point heating tune-up each fall, priority scheduling, and a 15 % discount on any repair. A clean, properly calibrated system can cut winter energy use by up to 20 %, extend equipment life, and reduce unexpected breakdowns. We also recommend replacing 1-inch filters every 30-60 days, keeping supply and return vents unblocked, and installing a smart thermostat to optimize run times based on Gruetli-Laager’s frequent temperature swings.
