Our Furnace Installation Services

When installing a new or replacement furnace in your home, the quality of the product is just as important as the workmanship. It is extremely important that the system is sized properly—a furnace that is too small will have to work overtime to get your house to the proper temperature, and a furnace that is too big will cycle on and off far too frequently, greatly reducing its efficiency.

At Michael Bonsby HVAC & Plumbing, our expert furnace installation specialists in Montgomery County, MD will be able to take measurements before installing your new furnace, ensuring it can heat your home as efficiently and effectively as possible.

We install new furnaces from a range of top-name brands and are American Standard and Mitsubishi authorized dealers.

Furnace Installation FAQs

I’m going on vacation. What temperature should I set my thermostat?

Before you leave to go on vacation, you definitely want to lower your thermostat – after all, why should you pay to warm an empty house? However, it’s NOT a good idea to turn the furnace off completely. If you have pets you’re leaving in the house, keep the temperature set around 65F – you don’t want your little guys to be freezing while you’re gone! If you don’t have pets (or if they’re coming with you), set your thermostat no lower than 55F. This temperature will ensure maximum energy savings while still being warm enough your pipes won’t freeze.

Should I leave my pilot on over the summer?

Many people worry the pilot will create heat and waste gas over the summer. And while this is true to an extent, it’s not as bad as you might think. Pilots use a very small amount of gas, and many times they can’t be relit during the fall – spiders tend to find their way into unlit pilot assemblies, clogging up the burners with webs and dead bugs! Also, the heat produced by the pilot keeps humidity and moisture out of the furnace in the summer that can cause it to rust.

Will a programmable thermostat help me even if I have an old furnace?

Yes! Analog thermostats typically operate within a 3 – 4 degree range while newer programmable thermostats are extremely accurate, which can help you stay comfortable and save more energy.
