FAQs
How do I know it’s time to replace my HVAC unit instead of repairing it?
In Graysville’s mixed-climate environment, most systems last 10–15 years. If your unit is near that age, requires frequent repairs, uses R-22 refrigerant, or your utility bills have risen sharply, replacement is usually more cost-effective. A free load calculation and inspection by our technicians can confirm whether repair or full replacement will save you more over the next decade.
What size HVAC system does my Graysville home need?
Proper sizing is critical for comfort and efficiency. We perform a Manual J load calculation that accounts for square footage, insulation levels, window types, sun exposure, and local temperature swings. This scientific approach prevents the common problems of oversized systems (short-cycling, humidity issues) and undersized systems (constant running, cold/hot spots).
How long does the HVAC replacement process take from start to finish?
Most residential replacements in Graysville take one full working day. The timeline breaks down as follows: (1) Pre-installation home evaluation and load calculation—about 90 minutes; (2) Equipment selection and proposal review—same or next day; (3) Permit acquisition—1–3 business days, handled by us; (4) Installation—6–10 hours, including removal of the old unit, new system placement, ductwork modifications, thermostat setup, and final quality check; (5) Post-install inspection by city officials when required.
Will a new HVAC system lower my energy bills?
Yes. Today’s high-efficiency heat pumps and air conditioners carry SEER2 ratings up to 20+ and gas furnaces up to 98% AFUE. Upgrading from a 10-SEER unit to a 16-SEER model can cut cooling costs by roughly 35%. We also install variable-speed and dual-fuel systems that fine-tune output to match Graysville’s seasonal swings, maximizing savings year-round.
Do I need permits or inspections for an HVAC replacement in Graysville?
Jefferson County and the City of Graysville require mechanical permits for any equipment replacement that alters electrical, gas, or refrigerant lines. As a licensed contractor, we pull all necessary permits, schedule inspections, and provide you with documentation for warranty validation and home resale. Homeowners don’t have to handle any paperwork.
What financing or rebate options are available for my new HVAC system?
We offer 0% APR financing for 12–60 months on approved credit, plus low-interest options up to 120 months. Alabama Power and TVA often provide rebates for ENERGY STAR heat pumps, and federal tax credits of up to $2,000 are available for qualifying high-efficiency equipment under the Inflation Reduction Act. Our comfort advisors will apply any utility rebates and manufacturer promotions directly to your quote so you pay the lowest net price.
