Why Installation Matters

A new furnace can last 15 years or more, but it’s only as good as the installation. A poor installation can lead to costly issues that may not show up right away. Selecting the right installer ensures your furnace runs efficiently and saves you money in the long run.

With proper installation, your furnace will perform at its best. Improper installation can cause problems that may require repairs over time, so don’t take any chances. Trust a professional team like Dave’s Heating and Air Conditioning to handle it.

What to Look for in a Furnace Installer

Here are a few tips for selecting the right heating contractor in Reston:

  • Licensing: This ensures the installer follows safety standards.
  • Insurance: Protects you in case of damage or accidents.
  • Experience: An experienced team will ensure proper installation.
  • Referrals and Reviews: Ask for recommendations and check customer feedback.
  • Guarantees: Look for a contractor who stands behind their work.

Preparing for Furnace Installation

On the day of your new furnace installation, we want to ensure everything goes smoothly. At Dave’s Heating and Air Conditioning, we recommend taking a few steps to prepare your home both indoors and outdoors. When our office contacts you to let you know we’re on our way, please:

  • Move any vehicles to clear the path for our truck, allowing easy access to the entry nearest the furnace.
  • Clear the path for the old furnace to exit and the new one to enter, and remove any items that could be damaged, like wall hangings.
  • Keep pets in a separate room to prevent them from being underfoot during installation.


Once our team arrives, they will introduce themselves, lay down floor protection, and review the installation plan, rechecking all measurements. The old furnace will be disconnected and removed, and the new one will be brought in and set up. The old unit will be scrapped and recycled. After everything is installed and all connections are made, the furnace will be tested for both safety and performance. We will make any necessary adjustments and then explain how to operate and maintain your new furnace. Our team will also clean up before leaving, ensuring your home looks just as it did before the installation.

We know furnace installation can be a big task, and we do our best to make it as efficient as possible. If you have any questions or special requests, don’t hesitate to contact us at 571.346.3940.

Maintain Your Furnace for Longevity

Once your new furnace is installed, it can last for decades—possibly even through your child’s school years—but only if you maintain it properly. Regular furnace maintenance is just as important as oil changes and inspections for your car. Without proper care, even the best furnaces lose efficiency and are more prone to breakdowns.

At Dave’s, we make furnace maintenance easy by offering a program that reminds you when it’s time for your annual service and provides the necessary maintenance. In the meantime, make sure to regularly check and replace your furnace filter to keep it running smoothly. As fellow Reston homeowners, we understand how easy it is to forget about furnace maintenance, which is why we’re here to partner with you in keeping your heating system efficient and trouble-free.
