Insulation & 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, ductwork, and insulation, 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, properly sized ductwork, and insulation. 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.

Insulation Services

Properly insulating your home, from the attic and walls to the basement or crawl space, can lower your utility bills and maximize your comfort. If your HVAC system struggles to maintain a consistent temperature throughout your home, poor or damaged insulation could be the culprit. 

The trained and certified team at F.H. Furr offers insulation services to keep your home’s temperature consistent and comfortable.

When you call us, we’ll start by auditing the overall performance of your home to determine if spray foam or cellulose insulation will best meet your needs. Then, we’ll get to work insulating your home, applying years of experience and skills to ensure a smooth, hassle-free installation.

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.

Insulation FAQs

No. Insulation helps maintain a consistent temperature in your home. Installing insulation will not affect the noise levels in your home.
Insulation is rated by R-value. The higher the R-value, the better the insulation value.

You may need insulation services if you notice:

  • Bare areas where insulation is missing or damaged
  • Cold spots on walls or floors
  • A drastic difference in temperature around doorways and windows
There are several types of insulation, all of which are designed for specific applications. To ensure you have the correct type of insulation for any given space, refer to our team.
Fiberglass and spray foam insulation can be used for different areas of your home. If you’re determining which type is better for insulating and simultaneously sealing air leaks, we recommend spray foam.
If your insulation is wet or water-logged, call our team right away to replace it. Failing to do so can create severe problems, such as mold and mildew growth.
Flammability varies by the type of insulation. Standard fiberglass insulation is mostly non-combustible, while the paper or foil surrounding the insulation is more flammable.
