FAQs
What HVAC certifications do your technicians hold and why are they important?
Every member of our Walland service team is NATE-certified (North American Technician Excellence) and EPA Section 608 certified for refrigerant handling. These credentials verify that the technician has passed rigorous, industry-standard exams on diagnostics, installation, and environmental safety. When a certified technician works on your equipment, you can trust the job will meet code, preserve your manufacturer’s warranty, and keep your system running at peak efficiency.
How often should I schedule maintenance for my heating and cooling system in Walland’s climate?
Twice a year—once in the spring for cooling equipment and once in the fall for heating. Walland’s humid summers and cool winters put year-round demand on HVAC systems, so semiannual tune-ups help prevent breakdowns, catch small issues before they escalate, and maintain energy efficiency. Our maintenance visits include cleaning coils, checking refrigerant levels, testing safety controls, calibrating thermostats, and replacing standard filters.
What are the signs my home needs improved ventilation or air quality solutions?
Common indicators include persistent dust, stale or musty odors, visible mold, frequent allergy or asthma flare-ups, excessive humidity (over 60 percent), or humidity that is too low in winter (below 30 percent). Uneven temperatures and condensation on windows also suggest poor air exchange. If you notice any of these conditions, a whole-house air quality assessment can identify the root cause and the best remedy.
Which indoor air quality products do you install and how do they work?
We offer high-MERV media filters, HEPA bypass filters, UV-C germicidal lamps, energy-recovery ventilators (ERVs), and whole-house humidifiers/dehumidifiers. Media and HEPA filters trap fine particulates such as pollen and pet dander; UV-C lamps neutralize airborne viruses, bacteria, and mold spores inside the air handler; ERVs exhaust stale indoor air while pre-conditioning fresh outdoor air to reduce energy loss; humidifiers add moisture during dry winter months, and dehumidifiers remove excess moisture in summer, both keeping relative humidity in the optimal 40-50 percent range.
Can your team handle emergency HVAC repairs, and what areas around Walland do you cover?
Yes. We provide 24/7 emergency service for no-heat, no-cool, or air-quality hazards. Our certified technicians arrive in fully stocked vans capable of repairing all major brands. In addition to Walland, we service Maryville, Townsend, Alcoa, and the greater Blount County area with an average response time of under two hours.
How can upgrading to a high-efficiency HVAC system save me money and improve air quality?
Modern heat pumps and furnaces with SEER2 ratings of 16+ and AFUE ratings of 95+ can cut energy consumption by up to 30 percent compared to units over 10 years old. Variable-speed blowers run longer at low speeds, which stabilizes temperatures, reduces humidity, and allows filters and UV lights to clean more air. Many high-efficiency systems also integrate smart thermostats and advanced filtration options, giving you better control over comfort and indoor air quality while lowering monthly utility bills and qualifying for local rebates or federal tax credits.
