FAQs
When is an emergency HVAC unit replacement necessary instead of a repair?
Emergency replacement is recommended when the existing system has a cracked heat exchanger, failed compressor, severe refrigerant leak, burned-out blower motor, or any other issue that poses a safety risk or leaves the home completely without heating or cooling. In Fountain City’s hot, humid summers and chilly winters, prolonged downtime can lead to indoor air-quality problems, frozen pipes, or heat-related health risks. If the unit is more than 12–15 years old and repairs would cost more than 40–50 % of the price of a new system, replacement is typically the smarter, more economical choice.
How fast can your technicians arrive for an emergency replacement in Fountain City?
We provide true 24/7/365 emergency service. Because our dispatch center is located right here in Fountain City, a certified technician can usually be at your door within 60–90 minutes—often sooner during normal business hours. Our fully stocked service vehicles carry the most common replacement parts and temporary cooling/heating solutions, so we can stabilize your home environment immediately while arranging the full system change-out.
What types of HVAC systems do you replace and install?
Our team is trained and licensed to replace traditional gas furnaces, central air conditioners, heat pumps, dual-fuel hybrid systems, ductless mini-splits, and high-efficiency packaged rooftop units. We are authorized dealers for leading brands such as Trane, Rheem, Lennox, Carrier, and Daikin, but we can service and replace any make or model. All installations adhere to Fountain City and Knox County mechanical codes and include a full Manual J load calculation to ensure proper sizing.
Will a new HVAC unit really lower my energy bills?
Yes. Today’s ENERGY STAR®-rated systems are up to 50 % more efficient than units manufactured just 10–15 years ago. Replacing an older 10 SEER air conditioner with a 16–18 SEER model or upgrading a 70 % AFUE furnace to a 95 % AFUE condensing furnace can cut annual utility costs by hundreds of dollars. We also optimize ductwork, add smart thermostats, and verify airflow to maximize savings and comfort in Fountain City’s variable climate.
How much does an emergency HVAC replacement cost, and do you offer financing?
Costs vary based on system size, efficiency rating, and any duct modifications, but most Fountain City homeowners spend between $4,500 and $12,000 for a complete replacement. Because emergencies are rarely planned, we partner with several financing providers to offer same-day approval, 0 % interest promotional plans, and low monthly payments stretching up to 120 months. We also guide you through available TVA energy rebates and manufacturer instant discounts to reduce upfront expenses.
What warranties and maintenance support come with my new HVAC system?
All of our replacements include a 10-year manufacturer parts warranty and a 1-year labor warranty, with optional extensions up to 12 years for both parts and labor. In addition, you receive a free first-year membership in our Comfort Shield maintenance program, which provides two precision tune-ups, priority service, and a 15 % discount on any future repairs. Routine maintenance keeps your warranty valid and ensures your new system operates at peak efficiency for its full lifespan.
