FAQs
What certifications do your heating and air-conditioning technicians hold?
Every member of our Jonesborough service team is EPA-certified and has completed North American Technician Excellence (NATE) accreditation. In addition, our technicians take part in ongoing factory-sponsored training for major HVAC brands so they stay current with the latest equipment, codes, and best safety practices.
Which HVAC services do you provide in Jonesborough and the surrounding area?
We handle the full spectrum of residential and light-commercial HVAC needs, including new system design and installation, seasonal maintenance, 24/7 emergency repairs, indoor-air-quality products, ductwork inspection and sealing, thermostat upgrades, and energy-efficiency audits.
How fast can you respond if my furnace or air conditioner breaks down after hours?
Our on-call technicians are available around the clock. Calls received before midnight are typically answered within 2 hours, and most Jonesborough addresses fall within our 30-mile rapid-response zone, allowing us to reach you quickly—often in less time than it takes for a tow truck.
Do you offer maintenance agreements, and what do they include?
Yes. Our Comfort Shield Maintenance Plan provides two precision tune-ups per year (one heating, one cooling), priority scheduling, no overtime charges, a 15% discount on parts and labor, and detailed system health reports so you can budget for future upgrades.
Which brands and system types can your certified technicians service or install?
Because our staff is factory-trained, we can work on virtually any major brand, including Trane, Carrier, Lennox, Rheem, Goodman, and Mitsubishi Electric. We service gas furnaces, heat pumps, central AC units, ductless mini-splits, packaged rooftop units, and high-efficiency boilers.
Are energy-efficient upgrades and financing options available?
Absolutely. We specialize in ENERGY STAR® certified equipment and variable-speed technologies that can cut utility costs by up to 30%. We also handle the paperwork for TVA EnergyRight and federal tax credits, and we offer flexible financing with approved credit so you can upgrade without large upfront costs.
