HVAC Repair Portsmouth VA | Call Power House

For your Portsmouth home, our energy audit starts with a comprehensive blower door test, which depressurizes your house to measure how much air is leaking in and out. We combine this with an infrared camera scan to visually locate hidden drafts, insulation gaps, and moisture issues. We also perform a duct blast test to check for leaks in your HVAC ductwork. This process specifically identifies why your system might be struggling with high humidity or poor cooling, providing you with a detailed report and prioritized recommendations to seal your home, improve comfort, and lower your energy bills.

High indoor humidity and an AC that can't keep up are often symptoms of the same problem: air leaks. In our humid Hampton Roads climate, warm, moist outdoor air constantly seeps into your home through cracks and gaps. This makes your air conditioner work much harder to remove both heat and moisture, reducing its efficiency and lifespan. Our blower door test quantifies this infiltration. By pinpointing and sealing these leaks—especially in attics, crawl spaces, and around windows—we help your HVAC system maintain a cooler, drier, and more comfortable environment efficiently, which can prevent breakdowns during the peak of summer.

Ductwork is often the hidden culprit behind high energy bills. If the ducts running through your unconditioned attic or crawl space are leaky, you could be losing 20-30% of the cooled or heated air your system produces before it ever reaches your rooms. This forces your HVAC to run longer and work harder. Our duct blast test pressurizes your duct system to measure the leakage rate. Sealing these leaks is one of the most cost-effective ways to improve system performance, balance temperatures room-to-room, and ensure you're getting the full benefit—and value—from every dollar you spend on heating and cooling.
