FAQs
When should I consider replacing my HVAC unit instead of repairing it?
Most systems last 12–15 years. If your unit is within that age range, needs frequent repairs, or your energy bills keep rising, replacement is usually more cost-effective. A new, high-efficiency model can cut heating and cooling costs by 20–40 %, offsetting the upfront investment over time.
What size HVAC system do I need for my Cowan home?
Correct sizing depends on square footage, insulation values, window count, ceiling height, orientation, and local climate data for Cowan. Our technicians perform a Manual J load calculation during the in-home assessment to ensure the new equipment is neither undersized (leading to comfort issues) nor oversized (causing short cycling and higher bills).
How long does a typical HVAC replacement take?
Most residential change-outs can be completed in one day. We schedule arrival around 8 a.m., remove the old system, set the new equipment, run new refrigerant lines or duct modifications if needed, pressurize and vacuum-test, then start up and balance airflow. Larger homes or extensive duct upgrades can extend the project to two days.
Are there energy-efficiency rebates or financing options available in Cowan?
Yes. TVA energy-right rebates, manufacturer promotions, and federal tax credits (up to $2,000 for high-efficiency heat pumps) can lower initial costs. We partner with local lenders to offer low-interest and 0 % promotional financing with terms up to 72 months, allowing you to spread the investment over affordable monthly payments.
What warranties come with a new HVAC installation by your team?
All equipment carries a 10-year manufacturer parts warranty when registered, plus our 1-year labor warranty. We also include a free one-year maintenance agreement, covering a spring AC tune-up and a fall furnace inspection, to keep the new system operating at peak efficiency and safeguard your warranty coverage.
How do I prepare my home for the installation day?
Clear a path to the indoor air handler and outdoor condenser, remove fragile items near work areas, secure pets, and set aside driveway space for our service vehicle. If a thermostat upgrade is included, know your Wi-Fi password. We protect flooring with drop cloths, but having the area tidy helps us complete the job quickly and safely.
