Is It Time to Replace Your Air Conditioner?

Holding on to an older system can cost you more in repairs and energy bills than a replacement. Here’s what to watch for:

  • Your system is 10–15+ years old
  • Frequent breakdowns or costly repairs
  • Rising energy bills without explanation
  • Uneven cooling or warm spots in your home
  • System uses outdated R-22 refrigerant
  • Poor humidity control or excess moisture

Why Proper AC Sizing Matters

Bigger isn’t always better when it comes to air conditioning. An oversized system short-cycles — it cools too fast, shuts off, and fails to properly dehumidify your home. An undersized system runs constantly and can’t keep up on hot days.

Our technicians perform Manual J load calculations — the industry standard method — to determine the exact system capacity your home requires based on square footage, insulation, window placement, local climate, and more.

✔  Consistent indoor temperatures throughout your home

✔  Proper humidity control – critical in Delmarva summers

✔  Lower monthly energy costs

✔  Longer system lifespan with less wear and tear

AC Installation FAQ

How much does AC replacement cost?
The cost of AC replacement varies based on system size, efficiency rating, brand, and installation complexity. Most residential AC replacements on the Delmarva Peninsula range from $4,000 to $12,000 or more depending on these factors. Our technicians provide detailed, transparent estimates during your free consultation.
How long does AC installation take?
Most residential AC installations are completed in a single day — typically 4 to 8 hours. Installations involving new ductwork or complex situations may take longer. We’ll give you a realistic timeline during your estimate.
What size air conditioner do I need?
System size (measured in tons of cooling capacity) depends on your home’s square footage, insulation levels, window area, ceiling height, and local climate. Our technicians perform Manual J load calculations to determine the correct size — never a simple rule-of-thumb guess.
Are rebates available on new AC systems?
Yes. Depending on the system you choose, you may qualify for federal tax credits, utility company rebates, and manufacturer promotions. We help identify available programs during your estimate so you can maximize savings on your investment.
Should I replace my furnace and AC at the same time?
If your furnace is also aging, replacing both systems together can reduce total installation costs, ensure matched equipment performance, and extend your warranty coverage. Our technicians can assess both systems and provide a recommendation based on your specific situation.
What brands do you install?
U.S. Heating & Air works with leading HVAC manufacturers. Visit our equipment page or ask your technician about current brand offerings and available efficiency levels for your home.
