Gas Furnace Installation & Replacement

Reliable, energy-efficient heat for your home.

Keep your home warm & comfortable with an energy-efficient gas furnace

Gas furnaces offer energy efficient heat for your home, and constant air circulation all year long. If you’re looking for a new heating system installation or a replacement for an older one, a gas furnace is one of the most reliable options. The experts at Pro-Tech HVAC Home are here to help guide you through the process of choosing the best new system for your home and budget.

We provide gas furnace installations, replacements, repairs and maintenance services throughout the Annapolis area.

If your current gas furnace is older, or no longer working as efficiently as it once was, it might be time to consider having it replaced. We’ll advise you whether it’s worth having repaired, or if replacing is the best option. Depending on the age of your current system, and the cost of repair, a gas furnace replacement might be the smartest way to move forward. 

We offer a variety of high-efficiency heating systems from our trusted brands. A new furnace should improve the comfort of your space, while also reducing your home’s overall energy consumption. 

We service our neighbors throughout the Annapolis area, complete with free installation estimates and financing options.

Your heating and cooling system is the largest energy user in your home.

When it’s time to replace your old gas furnace, Pro-Tech HVAC Home can help you find the furnace that’s right for your home. We’ll help you every step of the way, from performing a Manual J Load Calculation to determine the correct system size, to a hassle-free installation with a dedicated on-site Project Manager.

Why should I consider a gas furnace?

“Isn’t a gas furnace a bit—old-fashioned?” We sometimes hear this from customers. But the answer is that gas furnaces have kept up with the times and are more energy efficient—not to mention safer—than ever before. If you have a gas line, you should consider putting a gas furnace at the top of your list for installation or replacement.

Here are some reasons why:

  • Energy EfficiencyFew heating systems have as high energy efficiency ratings as gas furnaces. And since natural gas is a less expensive energy source than electricity and heating oils, you’ll save money each time the system turns on!
  • PowerThere isn’t a temperature low enough to defeat a gas furnace. These heating systems are top–rate in the amount of heating power they provide.
  • ConvenienceGas is piped right into your home, so you won’t have to worry about running out of heating oil or missing a delivery.

What Size Furnace Do I Need?

The size of your furnace depends on various factors in your home, such as the number of rooms, windows, insulation, surrounding shade, etc. 

Without the proper sizing, a gas furnace could be too small or too big for your home. If the system is too small, it overexerts itself to meet your energy needs and will not properly heat or cool your space. Not only will the unit constantly run, but it will also run up your electric bill. On the other hand, an oversized furnace will reach the goal temperature too quickly, thereby causing it to cycle off and on and wear down quicker.

At Pro-Tech HVAC Home, we perform a Manual J Load Calculation to determine what size furnace is correct for your home.
