HVAC Services Sterling VA | Call Xtreme Air Purification

Common signs include uneven heating or cooling between rooms, unusually high energy bills, and excessive dust around your vents. As local HVAC experts, we perform thorough pressure tests to pinpoint leaks in your ductwork and provide professional sealing to restore efficiency and comfort.

A faulty reversing valve can cause your heat pump to get stuck in one mode, meaning it may only heat or only cool. This is a common issue in our Sterling climate. Our technicians diagnose the valve and, if needed, perform a precise replacement to restore your system's ability to switch between heating and cooling functions properly.

Absolutely. Leaky ducts can pull in dust and allergens from attics or crawl spaces, circulating them throughout your Sterling home. Beyond sealing ducts, we offer advanced air purification solutions that integrate with your HVAC system to actively remove pollutants, providing cleaner air for your family.
