FAQs
When is it better to replace my HVAC unit instead of repairing it?
Most HVAC systems in Chattanooga last 10–15 years. If your unit is nearing that age, needs frequent repairs, consumes more energy than before, or uses the phased-out R-22 refrigerant, replacement is usually more cost-effective than continued repairs. A new system also provides improved comfort, quieter operation, and stronger warranty coverage.
What size HVAC system does my Chattanooga home need?
Proper sizing is determined through a Manual J load calculation that factors in your home’s square footage, insulation level, number of windows, orientation, and local climate data for Chattanooga’s hot, humid summers and mild winters. An accurately sized system prevents short cycling, maximizes efficiency, and ensures balanced heating and cooling in every room.
How long does an HVAC unit replacement take, and will I be without heating or cooling?
Most standard replacements take 4–8 hours, and even complex jobs with duct modifications rarely exceed two days. Our technicians arrive with all needed equipment, disconnect and remove the old system, set the new air handler and condenser, connect refrigerant lines and electrical, pressure-test, evacuate, and charge the system. Downtime is minimal, and we can provide temporary heaters or window AC units upon request.
How much should I budget for a new heating and air conditioning system in Chattanooga?
Total installed costs typically range from $6,000 to $12,000 for most homes, depending on system tonnage, SEER2/AFUE efficiency ratings, ductwork condition, and optional indoor-air-quality add-ons. High-efficiency heat pumps or dual-fuel systems can cost more up front but yield substantial long-term savings. We provide free in-home estimates so you know the exact price before work begins.
Will a modern HVAC system really lower my energy bills?
Yes. Replacing a 10-SEER air conditioner from the early 2000s with a 16–18 SEER2 unit or upgrading an 80 AFUE furnace to 96 AFUE can reduce cooling and heating costs by 20–40 percent. Variable-speed compressors, ECM blower motors, and smart thermostats further optimize energy use during Chattanooga’s temperature swings, giving you month-after-month savings.
Are rebates, tax credits, or financing available for HVAC replacements in the Chattanooga area?
Homeowners can claim up to $2,000 in federal tax credits under the Inflation Reduction Act for qualifying high-efficiency heat pumps and furnaces. Tennessee Valley Authority (TVA) EnergyRight and EPB often offer $150–$500 rebates for ENERGY STAR® systems, and many manufacturers provide seasonal promotions. We also offer 0% APR financing for up to 60 months with approved credit, so you can spread the investment over manageable payments.
