FAQs
What HVAC services do your certified pros offer in Greeneville?
Our team provides complete residential and light-commercial heating and air conditioning solutions, including system installation, replacement, seasonal maintenance, 24/7 emergency repair, indoor-air-quality upgrades (humidifiers, dehumidifiers, air purifiers, UV lights), ductwork inspection and sealing, thermostat upgrades, and energy-efficiency audits. Because we are factory-trained and NATE-certified, every service meets or exceeds manufacturer and state code requirements.
How often should I schedule maintenance for my HVAC system?
In Greeneville’s four-season climate, we recommend professional maintenance twice a year—one visit in early spring for your air-conditioning equipment and another in early fall for your furnace or heat pump. Regular tune-ups keep efficiency high, catch small problems before they become costly breakdowns, protect your manufacturer’s warranty, and can lower utility bills by up to 15%.
Are your technicians licensed and insured in Tennessee?
Yes. All of our service pros hold current Tennessee Mechanical Contractor licenses, EPA Section 608 refrigerant certifications, and full liability and workers’ compensation insurance. We also perform ongoing background checks and drug testing, so you can have total peace of mind when we’re working in your home or business.
What energy-efficient options do you recommend for Greeneville’s climate?
Because Greeneville experiences both humid summers and chilly winters, we often suggest high-efficiency heat pumps (15–20 SEER2), dual-fuel hybrid systems that pair an electric heat pump with a gas furnace, and variable-speed air handlers for tighter temperature control. We also install smart thermostats, ENERGY STAR ductless mini-splits for room-by-room comfort, and high-performance insulation and air-sealing upgrades to reduce overall load on the HVAC system.
How quickly can you respond to heating or cooling emergencies?
We offer true 24/7/365 emergency service with a technician on call at all times. In most Greeneville locations we can arrive within 2 hours of your call—often faster during regular business hours. Our fully stocked service vans carry common replacement parts so we can fix most issues on the first visit.
Do you offer financing or rebates for new HVAC installations?
Absolutely. We partner with several lenders to provide low-interest and no-interest financing plans with flexible terms up to 120 months. Our staff also tracks current TVA EnergyRight incentives, manufacturer rebates, and local utility rebates—saving customers anywhere from $200 to over $1,000 on qualifying high-efficiency equipment. We’ll handle the paperwork and apply the rebate at the point of sale whenever possible.
