FAQs
How do I know if my HVAC system in Birchwood needs to be replaced instead of repaired?
Common indicators include frequent breakdowns, uneven temperatures, rising utility bills, loud or unusual noises, and equipment that is 12–15 years old. A certified technician will perform a load calculation, inspect critical components (compressor, heat exchanger, blower motor), and compare repair costs to the price of a new, higher-efficiency system. If repairs exceed roughly 30–40 % of replacement cost or the unit uses R-22 refrigerant, replacement is usually the wiser choice.
What indoor air quality benefits can I expect from a new HVAC unit?
Modern systems feature variable-speed blowers that keep air moving at lower speeds, advanced filtration (MERV 13+), optional UV-C or bipolar ionization, and built-in humidity control. These upgrades reduce allergens, mold spores, and volatile organic compounds while maintaining 30–50 % relative humidity—ideal conditions for comfort and respiratory health.
How long does a typical HVAC replacement take, and will I be without heating or cooling?
Most residential replacements in Birchwood are completed in one day. Crews remove the old equipment, set the new indoor and outdoor units, update refrigerant lines, and test the system. You’re usually without heating or cooling for 4–8 hours. If ductwork modifications or IAQ accessories (like an ERV) are added, the job can extend to two days, but temporary space heaters or portable AC units can be provided on request.
Are there energy-efficiency rebates or financing options available for Birchwood residents?
Yes. TVA’s EnergyRight program and many local utilities offer $150–$500 rebates for qualifying heat pumps and high-efficiency gas furnaces (16+ SEER2 or 95+ AFUE). Federal tax credits under the Inflation Reduction Act provide up to $2,000 for heat pumps and $1,200 for IAQ upgrades such as high-efficiency air cleaners. Our company partners with lenders that offer 0 % APR for 12–18 months or low-interest terms up to 120 months.
What size HVAC unit do I need for my home?
Proper sizing depends on a Manual J load calculation that factors square footage, insulation levels, window types, orientation, occupant load, and air infiltration rates. Rule-of-thumb sizing (like one ton per 600 sq ft) often leads to oversized systems that short-cycle, waste energy, and fail to dehumidify. During your free estimate, we perform a room-by-room analysis to recommend the exact tonnage and duct adjustments your Birchwood home requires.
How often should the new system be maintained to protect my warranty and indoor air quality?
Manufacturers require professional maintenance at least once per year for cooling-only systems and twice per year for heat pumps and gas furnaces. Each visit includes cleaning coils, tightening electrical connections, checking refrigerant charge, replacing filters, and verifying airflow and combustion safety. Enrolling in our Comfort Club ensures priority service, documented inspections for warranty compliance, and filter reminders that keep your indoor air clean year-round.
