FAQs
How do I know it’s time to replace my HVAC unit rather than repair it?
In Graysville’s humid subtropical climate, most systems last 10–15 years. If your unit is in that age range, needs frequent repairs, struggles to maintain temperature, or causes higher utility bills, replacement is usually the most cost-effective long-term solution. Our technicians will run a full diagnostic and provide a repair-vs-replace cost comparison before you decide.
What size HVAC system is right for my Graysville home?
Proper sizing depends on square footage, insulation levels, window orientation, and even local weather patterns. We perform a Manual J load calculation that factors in Graysville’s highs, lows, and humidity to recommend the correct tonnage. An accurately sized unit prevents short-cycling, maximizes efficiency, and extends equipment life.
How long does a typical HVAC replacement take?
Most residential replacements in Graysville are completed in one day. We remove the old equipment, set the new condenser and air handler/furnace, connect refrigerant lines, update the thermostat, pull a vacuum to remove moisture, charge the system, and run a complete performance test. Complex ductwork modifications or indoor air-quality add-ons can extend the project to two days.
Will a new HVAC system lower my energy bills?
Yes. Modern systems carry SEER2 ratings of 14.3–20+—much higher than units installed a decade ago. In Graysville, where cooling can run nearly eight months a year, upgrading from a 10 SEER to a 16 SEER unit can cut electric cooling costs by up to 38%. High-efficiency gas furnaces (80–96% AFUE) also reduce winter heating expenses.
Do I need any permits or inspections for an HVAC replacement in Graysville?
Jefferson County requires a mechanical permit for HVAC replacements to ensure the work meets code and manufacturer specifications. Our team handles the permit application, schedules the county inspection, and supplies all documentation. You’ll receive a copy of the approved permit and inspection report for your records.
What financing or rebates are available for HVAC replacements?
We offer 0% APR financing for up to 18 months on qualifying systems and longer-term low-interest plans through our lending partners. Graysville residents may also qualify for manufacturer rebates (often $200–$1,200) and federal tax credits of up to 30% of project cost (capped at $600 for AC and $2,000 for heat pumps) under the Inflation Reduction Act. Our office will help you complete all paperwork to maximize savings.
