Furnace Repair and Replacement

Best Furnace Repair and Replacement in the Washington, DC Metro Area, Serving Maryland and Virginia


furnace repair replacementAn average of 50% of a home's energy expense comes from heating and cooling the home. The furnace does this work, but not all furnaces are created equal.

What Does The Furnace Do?

A furnace is a heater that distributes hot air throughout your house. The furnace heats the air, and using a large fan, blows the air through ductwork to distribute the heat throughout the house. The fan also pulls cool air back to the furnace so it can be reheated and distributed again.

Fuel For The Furnace

Many old furnaces use oil for fuel, but newer furnaces use propane or natural gas. An old oil furnace can be replaced for a propane or natural gas furnace as long as that fuel is locally available.

Classifications Of Furnaces

Furnaces are not just classified by the type of fuel they use, but also by:

1) BTU Output

The amount of heat a furnace can generate is listed in thousands of BTUs (e.g. 75,000btu)

2) Annual Fuel Utilization Efficiency

The AFUE tells you what percentage of energy going into the furnace is converted into heat for the home. It's a standard measure of efficiency used for all furnaces.

3) Configuration

There are two possible configurations:

  • Low-boy: A shorter furnace, with the blower behind the heat exchanger
  • High-boy: A taller furnace, with the blower underneath the heat exchanger

4) Combustion

An "atmospheric combustion" furnace uses a chimney to pump air out and uses indoor air for combustion. A "sealed combustion" furnace (also called a high-efficiency furnace) uses a small pipe to bring in outside air for combustion, and flue gases are pumped straight outdoors using a PVC exhaust pipe.

Higher Efficiency Means Greater Savings

The higher the efficiency rating of your furnace, the less money you will spend heating your home. Think about the numbers. If you have an old furnace that is 60% efficient, it means that 40% of the energy you are using to heat up air for your home (and spending money on!) is actually being lost through the chimney. However, with a new 95% efficient furnace, only 5% of the energy is lost. When you consider that over the lifetime of the furnace the cost of the fuel is the largest carrying cost of the unit, it makes sense to spend a little more money and get the most efficient furnace you can to save yourself heating costs in the long run.

We were unaware of what was involved in an energy audit and your audior took the time to explain everything. We were impressed with the report which told us the areas in which we need to take action on. He never pressured us to use any particular contractors, he just suggested that we go to the HomeEnergyTeam web site to select contractors of our own choice. He did an excellent job and we HIGHLY recommend the Home Energy Team Affiliates. We already have recommended them to several of our neighbors. Again, EXCELLENT JOB!

Your home energy audit proved to be very informative and helpful. I was not aware of the updraft created inside our walls because of the balloon framing construction. You said that that can cause heat to be pulled out of the house with the draft going up inside the walls and should be re-mediated. You also said that the attic insulation was insufficient and that fiberglass batts can leave spaces for around the edges causing heat loss and that it should have blown in insulation on top of what was there to seal the whole attic and increase the R factor. Thank You for all your advice and expertise. You made me aware of things I should consider and did the upgrades. I can already see the difference on my utility bills!
