FAQs
What types of heating and air-conditioning systems do you install and service in Mountain City?
We install, replace, and repair a full range of residential and light-commercial HVAC equipment, including high-efficiency gas furnaces, heat pumps, dual-fuel (hybrid) systems, central air conditioners, ductless mini-splits, packaged rooftop units, smart thermostats, and indoor air-quality accessories such as humidifiers and UV air purifiers. All installations meet or exceed Mountain City’s building codes and Energy Star guidelines.
How do I decide whether to repair or replace my existing HVAC equipment?
Our technicians follow a detailed checklist that factors in system age, current efficiency (SEER/HSPF/AFUE ratings), frequency of recent repairs, cost of the recommended repair, utility-bill history, and the specific heating-hour demands of Mountain City’s colder climate. As a rule of thumb, if your unit is 10–15 years old and the repair exceeds 30% of the cost of a new, high-efficiency system, replacement generally saves money long-term. We provide side-by-side cost-of-ownership comparisons so you can make an informed decision.
How fast can you respond to an emergency no-heat or no-cool call?
We offer 24/7 emergency service within Mountain City and surrounding Carter and Johnson counties. Calls received before 5 p.m. are typically handled the same day; after-hours calls are answered within 2–4 hours by an on-call technician. Our service trucks are stocked with the most common parts for the brands we install, allowing us to resolve 85% of emergencies on the first visit.
Do I need a permit or inspection for a new HVAC installation in Mountain City?
Yes. The City of Mountain City and Johnson County require mechanical permits for replacement or new HVAC systems that exceed 5 tons, alter structural supports, or involve new gas or refrigerant lines. We handle the entire permitting process, schedule the final inspection, and provide you with copies of the approved permit and inspection report for your records and warranty validation.
What will my installation or repair cost, and do you offer financing?
Every job begins with a free on-site evaluation and written estimate. Repair pricing is flat-rate, so you pay the quoted amount even if the job takes us longer. For installations, most high-efficiency replacements fall between $4,800 and $9,500, depending on capacity, duct modifications, and add-ons. We partner with Synchrony and local credit unions to offer 0% APR financing for up to 18 months and low-interest plans up to 72 months, subject to credit approval.
How can I keep my new HVAC system running efficiently and protect the warranty?
Manufacturers require documented preventive maintenance, typically one heating and one cooling tune-up per year. Our Comfort Club provides these visits, priority scheduling, a 15% repair discount, and automatically records each service to satisfy warranty terms. Homeowners can help by changing filters every 1–3 months, keeping outdoor units clear of leaves and snow, and monitoring utility bills for sudden changes that may signal a problem.
