FAQs
What does it mean for a technician to be NATE-certified, and why is it important?
NATE (North American Technician Excellence) certification is the HVAC industry’s most respected credential. To earn it, technicians must pass rigorous, proctored exams that test their knowledge of real-world installation, service, and maintenance practices. Hiring a NATE-certified pro ensures the work is performed to precise standards, which translates to better system performance, higher energy efficiency, fewer callbacks, and longer equipment life.
How often should I schedule maintenance for my heating and air conditioning system?
For most homes in Reliance, we recommend professional maintenance twice a year—once in the spring for your air conditioner and once in the fall for your furnace or heat pump. Regular tune-ups keep components clean and calibrated, help spot small issues before they become costly repairs, maintain manufacturer warranties, and can reduce energy bills by up to 15%.
Can your NATE-certified pros service all makes and models of HVAC equipment?
Absolutely. Our team trains continuously on every major brand and model, including Trane, Carrier, Lennox, Goodman, Rheem, and more. NATE’s comprehensive curriculum covers gas furnaces, air conditioners, heat pumps, mini-splits, and indoor air-quality accessories, so you can trust us to diagnose and repair any system in your home or business.
What signs indicate I may need to repair or replace my HVAC system?
Watch for uneven temperatures, unexplained spikes in utility bills, frequent cycling, strange noises or odors, and systems older than 10–15 years. If you notice any of these issues, a NATE-certified technician can perform a detailed inspection to determine whether a targeted repair or a full replacement will provide the best long-term value and comfort.
How can I improve the energy efficiency of my heating and cooling equipment?
Start with routine maintenance and filter changes, because a clean system runs more efficiently. Upgrade to a programmable or smart thermostat, seal and insulate ductwork, and ensure proper airflow by keeping vents unobstructed. If your equipment is aging, consider replacing it with a high-SEER air conditioner or ENERGY STAR®-rated furnace—our NATE-certified experts can size and install the ideal system for maximum savings.
Do you offer emergency HVAC services in Reliance, and what is the typical response time?
Yes. We provide 24/7 emergency heating and cooling service across Reliance and the surrounding areas. When you call, a live dispatcher assigns the closest on-call NATE-certified technician, and we typically arrive within two hours—often sooner during extreme weather. Our fully stocked service vehicles allow us to resolve most issues on the first visit, restoring your comfort as quickly as possible.
