FAQs
How do I know when it’s time to replace my HVAC unit instead of repairing it?
In Bluff City’s climate, an HVAC system typically lasts 10–15 years. Consider replacement if your unit is approaching this age, requires frequent or costly repairs, struggles to reach set temperatures, or causes a noticeable spike in utility bills. A certified technician can perform a cost-benefit analysis comparing repair expenses with the long-term savings of a new, high-efficiency system.
What size HVAC unit do I need for my Bluff City home?
Proper sizing depends on square footage, insulation quality, window count, sun exposure, and even ceiling height. Our certified technicians perform a Manual J load calculation to determine the exact capacity—measured in BTUs or tons—required for maximum efficiency and comfort. Installing the right-sized unit prevents short cycling, uneven temperatures, and unnecessary wear.
How long does a typical HVAC replacement take?
Most residential replacements in Bluff City can be completed in one day. The timeline covers removal of the old equipment, installation of the new indoor and outdoor units, ductwork adjustments if needed, refrigerant charging, thermostat setup, and a final system check. Complex duct modifications or add-ons such as indoor air quality upgrades may extend the project to two days.
Will a new HVAC system lower my energy bills?
Yes. Modern high-efficiency heat pumps and air conditioners carry SEER2 ratings of 15–20+, significantly outperforming older 8–10 SEER units. Homeowners often see energy savings of 20–40%. Our technicians can estimate projected savings based on your current usage, local utility rates, and the efficiency rating of the proposed system.
What warranties come with a new HVAC unit?
Most major manufacturers offer a 10-year parts warranty when the unit is registered within 60 days of installation. Our Bluff City installation team also provides a 1- to 2-year labor warranty, covering workmanship and installation-related issues. Extended labor warranties up to 10 years are available for additional peace of mind.
Do I need any permits or inspections for HVAC replacement in Bluff City?
Yes. Sullivan County and Bluff City require mechanical permits for HVAC replacements. As a licensed contractor, we obtain all necessary permits and schedule inspections with local code officials. This ensures your new system meets safety, efficiency, and code requirements, protecting your investment and home insurance coverage.
