It seems like everything comes with a microchip in it these days: cars, refrigerators and even toilets are all advertised as “smart.” Is it any surprise that furnaces are following suit? These miracle machines work in hundreds of tiny ways to keep you more comfortable and save you money on energy bills—what’s not to love?

Our favorite furnace recommendation for Montgomery County homeowners is the Evolution gas furnace from Bryant. EnergyStar, a government agency focusing on energy efficiency, has rated the Evolution one of the most efficient furnaces on the market today. You could save up to 23% on your energy bills thanks to the ultra-efficient furnace. But why else should you love Evolution?

  • When Gaithersburg AC & Heating installs the Evolution furnace with the Evolution thermostat, as we recommend, a whole new world opens up for you. Your thermostat becomes mission control for your whole-house comfort system. Change your humidifier, heat and air from one easy-to-use panel, get filter change reminders and program your home to automatically adjust to the perfect temperature.
  • Better maintenance. When a qualified technician comes to your home, he or she can work with the furnace to get incredibly detailed information about how it’s functioning, what needs an extra-tune up and where any trouble areas might be. It can help small problems from turning into big headaches and keep your furnace operating at its best.
  • It can perform in a number of applications and ranges in efficiency from 80% to up to 97%!  Depending on your home and your specific needs are requirements the Bryant Evolution Furnace is a great option to assist with saving you money and staying comfortable.
  • We all know that if you don’t like the weather in Montgomery County, just wait ten minutes and it’ll change. In the winter, that can often mean plummeting temperatures that leave your furnace struggling to keep up. But the Evolution furnace starts on a low warming cycle and gradually adjusts upward as the weather gets colder. That means no more uncomfortably cold mornings or blasts of heat—it’s constant, steady and cozy.
  • Noise reduction. Stop shouting over the sound of your furnace.  These Evolution furnaces are quiet!

Still not sure if an Evolution furnace is right for you? We’d love to help you determine the best heating system for your home. We service all of Montgomery & Frederick County, including Rockville, Germantown, Potomac, Olney and Clarksburg, and would love to help you live a more comfortable and efficient lifestyle with a new furnace.

It’s not news when we tell you that the past few years have been tough all across the country. Here in Montgomery County, good people are struggling to live in their homes with the dignity and safety they deserve. Maybe it’s a single mom in Rockville struggling to make ends meet or a widow in Germantown wondering how she’ll manage the upkeep on her house alone. Everyone’s story is different, but here in Maryland, we pull together and help each other out.

That’s why GAC Cooling & Heating (Gaithersburg Air Conditioning & Heating) supports Rebuilding Together Montgomery County. They know that sometimes because of age, economic hardship or health reasons, some people struggle to maintain their homes and live in warmth, safety and independence. Did you hear that first part, warmth? That’s where we come in.

As part of our work with Rebuilding Together Montgomery County, we perform maintenance work to HVAC systems at little to no cost and install systems for a reduced fee. We help 20 to 30 homeowners  every year and provide service as needed. To us, it’s just extending what we do every day to helping our community. We truly believe we are a part of this community, and why shouldn’t we be the ones to help?

Plus, it just feels good to help, like when we were able to assist a kind elderly lady who lost her husband and hasn’t had the money to keep up with repairs on her HVAC system or when we worked with a disabled veteran to install his first-ever air conditioner.

Besides helping people stay warm in the winter and cool in the summer, Rebuilding Together Montgomery County also helps install ramps and other accessibility features, fix safety hazards and leaky roofs, or just help with yard work and maintenance. Sometimes, it’s the little things that make a big difference.

If you or someone you know is in need of a little extra help, make a nomination for Rebuilding Together Montgomery County through a church or temple, schools, neighborhood associations or through self-referral. Or we’d love to see you out at a site—volunteers and donations are always welcome.

If Rebuilding Together Montgomery County isn’t the organization for you, we still urge you to get out there and make a difference in your town. Whether you help a neighbor in Potomac or donate to a food pantry in Olney, we all owe it to one another to make our county the best place to live and work.

While our summer’s been unusually mild in Montgomery County this year, you may still have noticed that even if your first floor is comfortable, your second story is sweltering. Or maybe it’s your basement that’s freezing. To some extent, these are natural fluctuations because warm air rises, but a dramatic difference, may be part of a larger issue with air flow in your home.

Ducts carry air from your air conditioner, furnace and/or heat pump and distribute it throughout the house. As air travels away from the heating or cooling source, it naturally loses some of its temperature. However, when you have leaky ducts, you wind up wasting air that you’ve paid good money to condition and make your home less comfortable at the same time. It’s a bad deal all around.

Don’t worry—there are some quick and easy fixes to make your ducts more air-tight. One of our favorite tools when working with clients in Rockville, Germantown and other cities is Aeroseal. Aeroseal is a spray that actually seals ducts from the inside out. A sealant is injected into the vent system. Tiny molecules are suspended in the air and pushed through your ductwork as your HVAC system runs. When air tries to escape through a leak, the molecules crash into the wall and seal the tiny hole. At the end of the process, your home is more efficient and you should notice a difference in your temperature in those problem areas.

Aeroseal is a great fix if your system is otherwise working properly, but if you’re looking at replacing your furnace and air conditioner, a good HVAC company will also look at your ductwork to make sure it can properly handle the incoming and outgoing airflow without putting undue stress on your heat exchange. Make sure your company always thoroughly investigates your duct system to make sure it can handle your airflow.

At GAC Cooling & Heating (Gaithersburg Air Conditioning & Heating), we always audit your ductwork system to make sure it’s working to its fullest potential and not wasting your hard-earned money or contributing to an uncomfortable house. We’ll have a solution for you, whether that’s using Aeroseal or otherwise sealing and rearranging your ducts for maximum efficiency. Call us today for more information.  877.448.2366
