Gas Fireplaces

Gas burning fireplaces are becoming increasingly popular. With the flip of a switch you can sit back and enjoy a cozy, warm fire without the mess of real logs or smoke and fumes.

Gas fireplaces are designed to look so similar to a real wood burning fireplace that many people can’t tell the difference. You may not get the nostalgic pop and snap of a real fire, but what you lack in ambiance you gain in extremely clean, versatile warmth and cost-effective convenience. You also have a wide variety of fireplace designs and installation options. You can choose the design that best matches your home and you have an option to install a fireplace in more rooms than ever before.

Air Ducts

According to the U.S. Department of Energy’s Energy Star program, leaky ducts in attics or crawlspaces can account for 20% or more of a home’s heating and cooling energy losses. This makes it difficult to keep your house comfortable and it can result in higher utility bills.

Some signs that you may have leaky ducts include:

  • High summer and winter utility bills
  • Rooms that are difficult to heat and cool
  • Stuffy rooms that never seem to feel comfortable
  • High amount of dust or debris in your air

Learn more about how you can prevent, detect, and fix air duct issues with the help of the professionals at Design Air. Find out more about duct testing, duct insulation, and duct sizing as they relate to and impact indoor air quality.

Indoor Air Quality

Between work and home life, the average person spends about 90% of their time indoors! Indoor air can be 2 to 5 times more polluted than outside air. In fact, the Environmental Protection Agency ranked indoor air quality as a top 5 environmental danger.

A well-insulated home can help with your energy bills by keeping a constant temperature but that also leads to the same air being recycled through your home each time your air conditioner or furnace run. Be sure you have proper filtration and air purification equipment in place to prevent allergens and bacteria from circulating around your air.

Design Air can help you breathe easy. Call us today at 406-251-7997 and we can put together a plan for your home!

Whole-House Humidifiers

The comfort of your home not only depends on the air temperature but also the amount of moisture in the air.

Cold weather typically means dry, uncomfortable air. Dry air can cause respiratory problems as well as damage wooden furniture. Whole home humidifiers emit water vapor to increase the humidity thus protecting you and your home.

For whole-house humidifiers, an annual service tune up and cleaning is recommended, usually performed at the same time as your furnace tune up. Simple adjustments and regular cleanings can help your family and home make the most of your humidifier’s benefits.

Contact us today at 406-251-7997 or request service online to schedule a repair or maintenance or a FREE in-home consultation to install or replace your whole house humidifier.

Gas Furnace Replacement in Missoula, MT 59802

“The 30 year old furnace at my folks place finally failed and I desperately needed it to be evaluated. I have to drive a long way to get to my folks place and the Design Air team was very accommodating to timeline/schedule. After a thorough review the tech showed me multiple concerns with the old furnace and very clearly explained why the furnace was failing. He gave me multiple options to choose from, and I decided to replace the system. A week later I met the replacement team at my folks place again and I just cannot tell you how impressed I was by the courtesy and professionalism of the team. They lined the entire floor-route from the front door to the furnace with canvas and plastic to ensure they didn’t impact the floor. They were quiet and fast and had the entire old system removed and they new system up and running by just shortly after lunch. What really impressed my was how they kept me informed of their progress throughout the morning; which was unexpected and really comforting. When they left the new furnace was working great and they gave me a great overview of what they did and how the new system would function. AND, when they were finished THE ENTIRE FURNACE ROOM WAS CLEANER THAN WHEN THEY ARRIVED… really impressive effort to go above and beyond my expectations. The team was wonderful and I just can’t say enough about the service and quality.

With respect and tremendous thanks to Griffin, Cody and Tristen.

Tristan also took the time to explain everything to me at the end so I know how to operate my new furnace which I really appreciated! Highly recommend!”
