FAQs
What types of heating and air-conditioning systems do you install in Harriman?
We install a full range of residential and light-commercial systems, including high-efficiency gas furnaces, heat pumps, dual-fuel (hybrid) systems, central air conditioners, ductless mini-splits, packaged rooftop units, and smart, Wi-Fi–enabled thermostats. Our comfort consultants will evaluate your home’s size, existing ductwork, insulation levels, and the local Harriman climate zone to recommend the ideal system for year-round comfort and energy savings.
How long does a complete HVAC system installation usually take?
For most single-family homes, a straightforward replacement—removing the old equipment and installing a new matched indoor and outdoor unit—takes one full working day. If new ductwork, electrical upgrades, or refrigerant line sets are required, the project can extend to two or three days. We give you a detailed timeline in advance and coordinate with any necessary subcontractors (electricians, carpenters, or roofers) so downtime is minimal.
What factors affect the total cost of a new heating and cooling system?
Pricing depends on several variables: 1) Equipment capacity (measured in BTU or tons) based on your home’s load calculation. 2) Efficiency ratings (SEER2 for cooling, HSPF2/AFUE for heating) — higher efficiency units cost more upfront but save on utilities. 3) System type (split vs. packaged, ducted vs. ductless). 4) Required duct modifications, insulation, or electrical upgrades. 5) Optional add-ons such as zoning, whole-home air purification, or dehumidification. 6) Local permit and inspection fees set by the City of Harriman/Roane County. We provide a written, line-item proposal so you can see exactly where your investment goes.
Do I need permits or inspections for an HVAC installation in Harriman?
Yes. The City of Harriman and Roane County require mechanical permits for any new or replacement HVAC equipment. Our team handles all permitting, schedules required inspections, and ensures the installation meets the International Residential Code (IRC), International Mechanical Code (IMC), and state electrical standards. You receive copies of the approved permits and inspection stickers for your records.
How can I be sure my new system will be energy-efficient and lower my utility bills?
We perform an ACCA Manual J load calculation to size the equipment precisely—preventing the energy waste and comfort issues caused by oversized or undersized units. We recommend ENERGY STAR–certified models, seal and pressure-test ductwork, and balance air flow room by room. After startup, we verify refrigerant charge, static pressure, and thermostat calibration. These steps, combined with available TVA or utility rebates, help you save 20–40 % on heating and cooling costs compared to older systems.
What warranties and maintenance plans come with a new installation?
Most of our featured manufacturers provide 10-year parts and compressor warranties when the system is registered within 60 days. We include a one-year labor warranty on workmanship, with options to extend labor coverage to 10 years. To keep warranties valid and maximize system life, we offer affordable preventive maintenance agreements that include two seasonal tune-ups, priority service, discounted repairs, and filter reminders.
