FAQs

What does it mean that your technicians are NATE-certified, and why is it important for an HVAC replacement in Shelbyville?

NATE (North American Technician Excellence) certification is the HVAC industry’s highest level of technician credentialing. To earn it, our installers must pass rigorous, proctored exams on safety, sizing, airflow, refrigeration cycles, electrical diagnostics, and local code compliance. When you schedule a replacement in Shelbyville, a NATE-certified professional ensures your new system is properly matched to our region’s hot, humid summers and chilly winters, is installed to manufacturer specifications, and meets the City of Shelbyville’s permitting requirements—protecting your comfort, energy savings, and equipment warranty.

How do I know when it’s time to replace my heating and air conditioning unit rather than repair it?

Most modern heat pumps and central air conditioners last 10–15 years in Shelbyville’s climate. Consider replacement when: • Repairs approach 30–50 % of a new system’s cost. • Energy bills are climbing even after routine maintenance. • Your current unit uses R-22 refrigerant, which is no longer being produced. • Comfort is uneven—certain rooms are always too hot or too cold. • The system cycles on and off frequently or makes unusual noises. A free in-home evaluation by our NATE-certified team will compare the long-term operating costs of keeping your old unit versus upgrading to today’s higher-efficiency models.

How long does a typical HVAC replacement take, and will I be without heating or cooling?

For most single-family homes in Shelbyville, a straight unit change-out takes one full working day. Our crew removes the old indoor and outdoor equipment, sets the new condenser/heat pump, installs the matching indoor coil or air handler, reconnects ductwork and high-/low-voltage wiring, evacuates and charges the refrigerant line set, and performs a commissioning test. You may be without heating or cooling for 4–8 hours, but we schedule replacements early in the day and provide portable heaters or spot coolers in extreme weather. Complex jobs—such as adding new duct runs, upgrading electrical service, or installing an IAQ (indoor air quality) package—can extend the project to two days.

How do you determine the right size HVAC system for my home?

Our technicians perform a Manual J load calculation rather than relying on the square-foot rule of thumb. We measure wall and attic insulation, window type and orientation, infiltration rates, number of occupants, and local weather data for Shelbyville’s design temperatures. Sizing is critical: an oversized unit short-cycles, creating humidity and comfort problems, while an undersized system runs continuously and wears out prematurely. After the load calculation, we present several equipment options—standard, high-efficiency, and variable-capacity—so you can choose the balance of comfort and budget that fits your goals.

Are there rebates, tax credits, or financing options available for a new HVAC unit in Shelbyville?

Yes. Customers replacing a 10-SEER or older system with qualifying ENERGY STAR rated equipment may be eligible for: • Federal tax credits of up to $2,000 under the Inflation Reduction Act (when applicable). • Utility rebates from Shelbyville Power or neighboring co-ops for heat pumps meeting minimum SEER2/HSPF2 levels. • Manufacturer promotional rebates that can save an additional $200–$1,000. We also offer 0 % APR financing for up to 60 months (with approved credit) and low-payment leasing programs. Our office handles the paperwork and provides you with the documentation needed for tax filing.

What kind of warranty and ongoing maintenance do you provide after installation?

All systems we install carry a 10-year manufacturer’s parts warranty and up to a 10-year labor warranty when you enroll in our Comfort Club maintenance plan. The plan includes two seasonal tune-ups, priority same-day service, a 15 % discount on out-of-warranty repairs, and complete documentation to keep your warranty valid. Our NATE-certified technicians inspect refrigerant levels, clean coils, tighten electrical connections, calibrate thermostats, and verify airflow at each visit—helping your new HVAC unit perform at peak efficiency throughout Shelbyville’s demanding heating and cooling seasons.
