FAQs
Why is proper ventilation especially important in Mountain City’s climate?
At Mountain City’s higher elevation, homes are often built tighter to conserve heat during cool winters and reduce energy costs. While this saves energy, it also traps moisture, allergens, and pollutants indoors. Adequate mechanical ventilation exchanges stale air with fresh outdoor air, helping control humidity, prevent mold growth, remove airborne contaminants, and keep your HVAC system running efficiently.
How often should my ventilation or HRV/ERV system be inspected and serviced?
We recommend a professional inspection every 12 months. Filters usually need to be replaced or cleaned every 3–6 months, depending on dust levels, pets, and outdoor pollen counts. Annual service includes cleaning the core or wheel of HRV/ERV units, checking fans, verifying airflows, and ensuring the controls are calibrated so the system operates at peak efficiency.
What are the best ways to improve indoor air quality if someone in my home has allergies or asthma?
Combine proper ventilation with targeted air-cleaning solutions: 1) Install a high-MERV or HEPA media filter in your HVAC system to capture fine particulates. 2) Use a balanced HRV/ERV to introduce fresh, filtered air without major energy loss. 3) Add UV-C or photocatalytic air purifiers to neutralize bacteria and viruses. 4) Keep humidity between 30–50 % with whole-house humidifiers or dehumidifiers. Our specialists can test your air and design a customized package.
Can an energy-recovery ventilator (ERV) really lower my heating and cooling bills in Mountain City?
Yes. An ERV captures up to 70–80 % of the heat (and in summer, the coolness) from exhaust air and transfers it to incoming fresh air. This means your furnace or AC works less to reach your set temperature. In Mountain City’s climate, homeowners typically see 10–20 % HVAC energy savings while also getting continuous fresh air.
How do I know if my attic or crawl space needs additional ventilation?
Warning signs include excessive attic heat in summer, ice dams in winter, musty odors, visible mold, or warped roof decking. In crawl spaces, look for condensation on joists, mildew, or rusted metal. Our team can perform a ventilation assessment, measure moisture levels, and recommend passive vents, powered fans, or vapor barriers as needed.
