FAQs
How do I know it’s time to replace rather than repair my HVAC system in Calhoun?
Most systems last 12–15 years. If yours is in that age range, needs frequent or expensive repairs (over 30 % of the cost of a new unit), or can’t maintain comfort during Calhoun’s hot, humid summers and cool winters, replacement is usually the smarter investment. A Nate-certified technician can run a cost-of-ownership comparison that factors energy savings, repair history, refrigerant phase-outs, and warranty status to help you decide.
What does it mean to have a NATE-certified technician replace my HVAC unit?
NATE (North American Technician Excellence) is the nation’s largest independent certification program for HVAC professionals. Passing the NATE exams proves a technician’s knowledge of proper sizing, installation, airflow, charging, electrical diagnostics, and local code compliance. Choosing a NATE-certified team in Calhoun ensures your new system is installed to manufacturer specifications, maintains its warranty, and performs at the published efficiency ratings.
How long will an HVAC replacement take from start to finish?
For most residential jobs in Calhoun, the on-site portion is completed in one day. We typically arrive by 8 a.m., remove the old equipment, set the new indoor and outdoor units, update refrigerant lines and electrical, pressure-test and evacuate the system, charge it, and commission the thermostat. More complex projects—such as duct modifications, zoning, or indoor air-quality add-ons—may extend the work to two days, but you will have heating or cooling the same night.
How is the right size HVAC system determined for my home?
Our NATE-certified estimators perform an ACCA Manual J load calculation, which measures your home’s square footage, insulation levels, orientation, window efficiency, infiltration rate, and duct losses. Calhoun’s design temperatures (92 °F summer, 24 °F winter) are used to ensure the new unit is neither oversized (leading to short cycling and humidity problems) nor undersized (struggling on peak-load days). The result is balanced comfort, longer equipment life, and lower utility bills.
What rebates, tax credits, or financing options are available for HVAC replacements in Calhoun?
Energy-efficient heat pumps and furnaces that meet ENERGY STAR Tier 2 criteria may qualify for federal tax credits of up to $2,000 under the Inflation Reduction Act. Georgia Power and local EMCs often offer $150–$400 rebates for high-efficiency systems or smart thermostats. We partner with lenders that provide 0 % APR promotional financing for 6–18 months or low-interest plans up to 120 months, subject to credit approval. Our staff will handle the paperwork so you receive every available incentive.
How should I maintain my new HVAC unit after installation?
Change your air filter every 1–3 months, keep the outdoor coil clear of leaves and grass clippings, and schedule biannual maintenance (spring for cooling, fall for heating) with our NATE-certified technicians. During each visit we clean coils, verify refrigerant charge, test safety controls, tighten electrical connections, and calibrate the thermostat. Regular service keeps your warranty valid, preserves the SEER2/HSPF efficiency you paid for, and can add 3–5 years to the system’s lifespan.
