FAQs
What qualifies as an HVAC emergency that would require a 24/7 unit replacement in Vonore?
An HVAC emergency is any situation that jeopardizes your family’s safety, health, or comfort and cannot wait until normal business hours. Examples include total system failure during extreme heat or cold, a unit that is smoking or sparking, carbon-monoxide alerts from a cracked heat exchanger, major refrigerant leaks, or an elderly or medically fragile occupant who depends on climate control. If you are unsure, call us—our dispatcher will quickly assess the situation and advise whether an immediate replacement visit is necessary.
How fast can your technicians arrive for an emergency replacement call in Vonore?
Because we staff live dispatchers around the clock and position fully stocked service vehicles throughout Monroe County, our average arrival time within Vonore city limits is 60–90 minutes after your call. In severe weather or high-volume events we prioritize life-safety cases first, but you will always receive a realistic ETA by text or phone, and continual updates en route. If travel is delayed, we can often guide you by phone to shut off power or gas safely until we arrive.
Will you have a new heating or cooling unit on hand, or will I have to wait for parts to be ordered?
For the most common residential sizes (1.5-5 ton air conditioners, heat pumps, and 40-120k BTU gas furnaces), we keep replacement equipment in our local warehouse and on a dedicated box truck that is on call 24/7. If your home requires a less common capacity or specialty product, we can usually source it from a Knoxville distributor the same day. In the rare event that a unit must be factory-ordered, we install high-performance temporary heating or cooling equipment at no extra charge until the permanent system arrives.
Which brands and efficiency levels do you install during emergency service?
Our emergency inventory includes ENERGY STAR® rated systems from Trane, Carrier, Goodman, Rheem, and American Standard. We stock single-stage, two-stage, and variable-speed options up to 18 SEER2 for heat pumps and air conditioners, and up to 96% AFUE for gas furnaces. When time is critical, we focus on models that match your home’s ductwork and electrical/gas capacities to ensure a code-compliant, same-night installation. After the crisis is resolved, you can still upgrade or add accessories such as smart thermostats, media filters, or UV air purifiers within 30 days at standard pricing.
How much does an emergency HVAC replacement cost and do you offer financing?
Because emergency replacements occur outside normal hours, there is a flat after-hours deployment fee of $189, which is waived if you proceed with a full system installation. Total installed prices typically range from $4,800 to $9,500, depending on system size, efficiency level, and whether both the indoor and outdoor units are replaced. We partner with Synchrony and Wells Fargo to provide 0% APR plans for 18 months or low-payment options up to 120 months, even at 2 a.m. Our technician can process approvals on a tablet within minutes so your replacement can begin immediately.
Is my new unit covered by a warranty and will you handle removal of the old system?
Yes. All emergency replacements include the same manufacturer’s warranty you would receive during normal business hours—typically 10 years on parts and up to 10 years on compressor or heat exchanger when registered. Our company adds a full one-year labor warranty, plus free check-ups at 6 and 12 months. We handle all permitting, haul away your old equipment for environmentally responsible disposal, and register the new system on your behalf. You receive digital and printed warranty certificates before we leave your driveway.
