Q&A

How can I tell if my Saint Louis home's HVAC system is the wrong size?

Signs include rooms that are unevenly heated or cooled, your system constantly cycling on and off, unexpectedly high energy bills, and excessive humidity. An improperly sized system works harder, wears out faster, and costs you more. We provide precise load calculations to determine the correct size for your home's layout and insulation.

What are the most common signs of air duct leaks in my house?

Look for rooms that are difficult to heat or cool, unusually high dust levels, whistling sounds from your ducts, and your HVAC system running constantly without reaching the desired temperature. Leaky ducts waste conditioned air inside your walls and attic. We perform thorough inspections and use professional sealing methods to restore efficiency and comfort.

Can you fix my duct leaks without replacing my entire HVAC system?

Absolutely. In many Saint Louis homes, sealing existing ductwork is a highly effective and cost-efficient solution. We locate leaks at connections, seams, and in accessible runs, then seal them with mastic or metal-backed tape. This often resolves comfort issues and reduces strain on your current system, potentially extending its lifespan.
