FAQs
How do I know it’s time to replace my HVAC unit in Johnson City?
Most systems have a life span of 12–15 years. Signs it’s time for replacement include frequent breakdowns, rising energy bills, uneven temperatures, excess humidity, loud operation, or the use of R-22 refrigerant, which is now phased out. A professional evaluation can confirm whether repair or replacement is more cost-effective.
What size HVAC system does my home need?
Proper sizing depends on the square footage of your home, insulation levels, number of windows, ceiling height, local climate data for Johnson City, and even occupants’ lifestyle. Our technicians perform a Manual J load calculation to ensure your new unit delivers optimal comfort, efficiency, and longevity without short-cycling or excessive run times.
How long does a typical HVAC replacement take?
Most residential replacements are completed in a single day, including removal of the old unit, installation of the new equipment, thermostat setup, ductwork adjustments, start-up testing, and a walkthrough of system operation. Larger homes, zoning upgrades, or extensive duct modifications can extend the job to two days.
Will a new HVAC system lower my energy bills?
Yes. Modern high-efficiency heat pumps, air conditioners, and furnaces feature SEER2 ratings up to 20+ and AFUE ratings above 95%. Upgrading from a 10–12 SEER or 80% AFUE unit can cut cooling and heating costs by 20–40%. Our team helps you choose ENERGY STAR® systems and can calculate estimated savings specific to Johnson City utility rates.
Are there financing options or rebates available for HVAC replacements?
Absolutely. We partner with trusted lenders to offer low-interest and no-interest financing plans with flexible terms. In addition, many high-efficiency units qualify for local utility rebates, manufacturer incentives, and federal tax credits under the Inflation Reduction Act—up to $2,000 for heat pumps. We handle the paperwork so you capture every dollar of savings.
What kind of maintenance will my new HVAC system require?
To keep your warranty valid and maintain peak efficiency, schedule professional maintenance twice a year—one visit before cooling season and one before heating season. This includes cleaning coils, checking refrigerant levels, testing safety controls, and replacing filters. Between visits, change or clean your air filters every 30–90 days and keep outdoor units clear of debris.
