Air Sealing in DC, Maryland & Northern VA

While modern HVAC systems offer more energy efficiency than ever, you need more than a new heat pump, furnace, or air conditioner to maintain an energy-efficient and comfortable home.

Without proper air sealing and ductwork, your HVAC system will work harder to heat or cool your home, leading to costly energy bills each month.

A healthy and comfortable home starts with air sealing and properly sized ductwork. For over 40 years, F.H. Furr Plumbing, Heating, Air Conditioning & Electrical has been committed to the satisfaction and comfort of our customers.

Turn to our team when you’re ready to take control of your whole-home comfort and energy efficiency. Contact us today to request an appointment.

Air Sealing

Doors, windows, ductwork, and cracks can allow air to leak from your home. Without attention, air leaks will cause your HVAC system to work harder, leading to high energy costs and discomfort. Air sealing is an excellent way to improve the energy efficiency of your home and HVAC system.

If you need air sealing services in the DC metro area, call F.H. Furr. We’ll locate hidden air leaks throughout your home and apply a long-lasting solution.

Where Do Air Leaks Commonly Occur?

Finding the source of an air leak is challenging without help from an expert. Air leaks are most common in these areas:

  • Doors
  • Windows
  • Baseboards
  • Basements
  • Attics
  • Ductwork

Improving comfort and efficiency goes beyond air sealing and duct sizing. Indoor air quality solutions like duct cleaning, humidifiers, and dehumidifiers help reduce dust, control humidity, and create a healthier environment for your family. Pairing these services with professional air sealing ensures your HVAC system runs efficiently while delivering clean, comfortable air throughout your home.
