Install AC in Ashburn, VA

Repair often makes more sense when your system is under 10 years old and the fix is a single, isolated part. If your Ashburn home's AC is 12 to 15 years old and you are seeing repeated breakdowns or rising energy bills, replacement usually saves more money over time.

Not always, but the indoor coil and air handler must be matched to the new outdoor unit for the system to work correctly. A Kelvin Services technician can assess your existing equipment in Fairfax or Ashburn and tell you whether your furnace is compatible before any work begins.

Yes, a heat pump provides both cooling and heating from a single system, which can simplify equipment and reduce operating costs. It is a practical option for many homes in the Sterling and Leesburg area, and we can walk you through whether your home's setup supports one.

The right size is determined by a Manual J load calculation, which accounts for your home's square footage, insulation levels, window placement, and local climate. Skipping this step and guessing on size leads to a system that either short-cycles or runs constantly without ever catching up.

Yes, older homes in Ashburn and across Northern Virginia often have ductwork that was sized for less efficient systems and may have developed leaks or damage over time. We inspect the duct system before installation so you know exactly what condition it is in and whether any updates are needed to get full performance from your new equipment.

Look for a contractor who performs a proper load calculation before recommending equipment and inspects your existing ductwork rather than assuming it is fine.
