Heating Installation Services

Our Sterling VA, & Rockville heating installation team have experience with a variety of different home heating systems, including furnaces, heat pumps, or boilers. Whether you have a dated system you need to replace, or you want to install a completely new heater, our technicians can evaluate your property and provide you with the best heating system to meet your needs.

Installing a proper heating system isn’t just for comfort, it can also help make your home more energy efficient, which can help you save money each month in energy. Also, a modern heating system can improve the air quality in your home, reducing the level of contaminants and allergens in your living space. Depending on your needs, our NATE-certified technicians can get to work installing a new system or replacing your old one with speed and efficiency.

3 ways to help keep your heating unit from freezing:

  • Dirty coils: Dirt on your heat pump’s condenser coils don’t allow them to pull in as much heat as they need to properly warm your home. When this is the case, your coils can’t maintain a constant operating temperature, and as a result over time they accumulate too much frost and your system freezes over.
  • Dirty air filter: The air filter in your system needs to be clean in order to get the maximum amount of airflow over your compressor coils. If they don’t, the heat can’t radiate back into your home properly, and that could mean trouble for your heat pump. Changing your air filter can ensure your blower motor can pull as much air as possible through your system, making both more efficient and less likely to freeze over.
  • Dirty outdoor unit area: The area around your outdoor unit needs to be open and free from dirt, dust, leaves, and other debris that can accumulate and restrict airflow through it. It’s a good idea to regularly inspect your outdoor unit and sweep away any debris, including any accumulated snow, from a radius of at least two feet around your outdoor unit. You should also make sure the land your outdoor unit sits on hasn’t settled or shifted, which can seriously affect your system’s ability to work properly.
