Heating Services in Campbell

Furnaces are workhorses, but they don’t last forever. The U.S. Department of Energy recommends replacing a troublesome furnace if it’s more than 15 years old. When the time comes for you, you can depend on National Heating and Air Conditioning to correctly size your furnace. If you buy one too small, it will run longer than necessary to reach the thermostat setting. And if you buy a furnace that is too large, it will reach the desired temperature too quickly and then abruptly shut off—a process that is called short cycling that will prevent your home from heating properly. It can undermine the efficiency of a furnace and compromise its lifespan. Sizing a furnace accurately takes time, but we will always take the time to get it right because your comfort depends on it.

Besides furnace installation, we offer:

Air conditioners don’t last forever, either, but you can beat the odds with diligent maintenance. We recommend replacing an air conditioner if it is more than 10 years old. It’s a big investment, but it’s one that will pay off because many of today’s models are so energy-efficient that they can make up the cost difference in energy savings. Add on improved indoor air and more consistent indoor temperatures and you’ll understand why many Campbell residents consider a new air conditioner one of the best investments they’ve made in their home.

In addition to air conditioner installation, we offer:

Insulation Services in Campbell

You could have the sleekest, most energy-efficient furnace and air conditioner that money could buy. But if your home isn’t properly sealed and insulated, you could be squandering a small fortune every month. The envelopes of most homes—the roof, attic, subfloor, exterior doors, windows, and exterior walls—can be more like sieves if they are not properly sealed and insulated. Think of it like leaving a window open all the time—all of your valuable heated or cooled air escapes, making it all the more difficult for your home to reach the desired temperature.
