FAQs
How do I know it’s time to replace my HVAC unit in Cowan rather than repair it?
In Cowan’s mixed-humid climate, systems typically last 10–15 years. If your unit is approaching this age, needs frequent or costly repairs, suffers from uneven temperatures, or your utility bills keep rising despite regular maintenance, replacement is usually the most economical choice. A new high-efficiency system can cut energy costs by 20–40 % and deliver better comfort.
What size HVAC system is right for my Cowan home?
Proper sizing depends on a Manual J load calculation that factors in square footage, insulation levels, window orientation, local climate data for Cowan, and even occupant lifestyle. Oversized units short-cycle and waste energy, while undersized units run constantly and wear out early. Our technicians perform a full load analysis to recommend the exact capacity—measured in BTUs or tons—needed for peak efficiency and comfort.
How energy-efficient are today’s state-of-the-art replacement units?
Modern heat pumps and air conditioners can reach SEER2 ratings of 18–25+, and furnaces achieve AFUE ratings up to 98 %. Variable-speed compressors and smart inverter technology allow the system to modulate output precisely to demand, reducing energy use and humidity levels. Many models qualify for ENERGY STAR® and may be eligible for federal tax credits and Tennessee Valley Authority (TVA) rebates.
What is included in your HVAC replacement service in Cowan?
Our turnkey service covers: onsite consultation and Manual J sizing; equipment selection from leading brands; removal and eco-friendly disposal of the old unit; any necessary duct modifications or sealing; installation of the new system with factory-authorized procedures; start-up testing and airflow balancing; smart thermostat setup; permitting and code compliance; and a final homeowner walkthrough with maintenance tips.
How long does an HVAC replacement take and will I be without heating or cooling?
Most residential replacements in Cowan are completed in a single day. We schedule work to minimize downtime—typically only a few hours without conditioning. If extensive duct or electrical upgrades are required, the project may extend to two days, but we’ll provide temporary comfort solutions if needed.
What warranties, maintenance plans, and financing options do you offer?

We offer affordable preventive maintenance plans that include biannual tune-ups, priority service, and parts discounts. For budgeting, 0 % APR financing for up to 60 months is available with approved credit, as well as low-interest options and short-term payment plans.
