FAQs
How can I tell whether it’s time to replace my existing air conditioner rather than repair it?
In Blountville’s warm, humid summers, your AC works hard. If your system is more than 10–12 years old, needs frequent or costly repairs, struggles to keep your home comfortable, or uses the phased-out R-22 refrigerant, replacement is usually the most economical choice. A new high-efficiency unit can cut cooling costs by 20–40 %, eliminate repair headaches, and qualify for rebates that offset the initial investment.
What size air conditioning system do I need for my Blountville home?
Proper sizing depends on your home’s square footage, insulation levels, number of windows, occupancy, and local climate data. An HVAC load calculation (Manual J) performed by our technicians factors in Blountville’s design temperature (about 90 °F summer / 15 °F winter) to recommend the right tonnage. Oversized units short-cycle and waste energy; undersized units run nonstop and still can’t keep up. A professional load calculation ensures balanced comfort and peak efficiency.
How long does an AC replacement take and will I be without cooling during the process?
Most standard system replacements are completed in one day. We arrive with the new equipment, safely remove and recycle the old unit, make any duct or electrical modifications, install the new condenser, air handler, and thermostat, and pressure-test and evacuate the refrigerant lines. Your home may be without cooling for 4–8 hours, but we schedule work in the morning to restore comfort before the late-afternoon heat sets in. Complex jobs involving duct renovations or heat-pump conversions may take an extra day.
Are there high-efficiency options that can lower my monthly utility bills?
Absolutely. Today’s air conditioners and heat pumps reach SEER2 ratings of 16–20+, far above the 13-SEER units commonly installed in the early 2000s. Variable-speed compressors, ECM blower motors, and smart thermostats adjust output to match your exact cooling load, trimming energy use. In Blountville, where electricity rates average 11–12 cents/kWh, upgrading from a 10-SEER to an 18-SEER system can save roughly $350–$450 per year on a 2,000 sq ft home.
Do you offer financing or local rebates for HVAC replacements in Blountville?
Yes. We partner with several lenders to provide low-interest and 0 % promotional financing plans so you can spread the cost over 6–120 months. Bristol Tennessee Essential Services (BTES) and local TVA programs often offer rebates of $200–$400 for ENERGY STAR® heat pumps and dual-fuel systems. We handle the paperwork and apply all available manufacturer rebates so you receive the maximum savings upfront.
What maintenance does a new HVAC system require after installation?
Even the most advanced system needs regular care to maintain its warranty and efficiency. Change or clean filters every 1–3 months, keep the outdoor condenser free of leaves and debris, and schedule professional maintenance twice a year—spring for cooling, fall for heating. Our Comfort Club plan includes coil cleaning, refrigerant checks, thermostat calibration, electrical tightening, and a written performance report, ensuring your new system continues to deliver reliable comfort for 15 years or more.
