FAQs
When should I consider replacing my heating or air-conditioning system in Johnson City?
Most heat pumps, air conditioners, and furnaces last 10–15 years in our region. If your equipment is approaching that age, needs frequent repairs, produces uneven temperatures, or causes utility bills to spike, a replacement is usually more economical than another major repair. Modern high-efficiency systems can cut energy use by 20–40 %, so the savings often offset the investment.
How do I know what size HVAC system my Johnson City home needs?
Proper sizing is critical for comfort and efficiency. We perform a detailed Manual J load calculation that factors in square footage, insulation values, window orientation, air leakage, and local climate data for Johnson City (4,300 heating degree days and hot, humid summers). This scientific approach ensures you get a system that isn’t too large (causing short-cycling and humidity issues) or too small (running constantly and wearing out prematurely).
What is involved in the replacement process, and how long does it take?
A typical residential change-out takes one full day: 1. Pre-job walk-through and protective floor coverings (30 min). 2. Safe recovery of existing refrigerant (30 min). 3. Removal of old indoor and outdoor units (1–2 hrs). 4. Installation of the new air handler/furnace, condenser or heat pump, refrigerant lines, drain, and electrical upgrades (4–5 hrs). 5. Charge, start-up, and performance verification (1 hr). 6. Customer orientation and cleanup (30 min). Complex duct modifications, zoning, or indoor air-quality add-ons may extend the job to two days.
Are there rebates or tax credits available for new HVAC systems in Johnson City?
Yes. Through TVA’s EnergyRight program and the local utility BrightRidge, qualifying high-efficiency heat pumps can earn rebates of $150–$500. Federal tax credits under the Inflation Reduction Act offer up to 30 % of the project cost (max $2,000) for systems rated ≥16 SEER2 or ≥97 AFUE furnaces. We handle all paperwork and will apply the rebates as an instant discount whenever possible.
How much will a system replacement cost, and do you offer financing?
Prices vary with size, efficiency, and options, but most complete replacements in Johnson City range from $6,500 for a base 14.3 SEER2 split system to $12,000+ for a two-stage or variable-speed heat pump with smart controls and air-quality upgrades. We partner with Wells Fargo and Synchrony to provide 0 % APR plans for 12–18 months or low fixed-rate terms up to 60 months, subject to credit approval. We’ll present clear, written proposals so you can choose the comfort and payment option that fits your budget.
