How can I improve indoor air quality in Lee's Summit?

To improve indoor air quality in Lee's Summit, start by regularly changing your HVAC filters, scheduling routine maintenance, and using air purifiers. Consider duct cleaning if your home has excessive dust or allergy symptoms. Proper ventilation and keeping your home clean are key to healthier air.

How often should I service my HVAC system in Lee's Summit?

It’s ideal to service your cooling system each spring and your heating system each fall to ensure you find small issues before they become big problems.

How often should I have my air ducts cleaned in Lee's Summit?

It’s generally recommended to have your air ducts cleaned every 3 to 5 years in Lee's Summit, or more often if you notice dust buildup, allergies, or musty odors. Homes with pets, recent renovations, or high pollen levels in Lee’s Summit may benefit from more frequent cleanings to maintain healthy indoor air quality.

How often should I schedule AC maintenance in Lee's Summit?

You should schedule AC maintenance once a year, ideally in the spring before the cooling season starts in MO. Regular tune-ups help your system run efficiently, prevent breakdowns, and extend the life of your unit, especially important in Lee's Summit's summer climate.

What size HVAC system is right for my home in Lee's Summit?

The right HVAC system size for your home in Lee's Summit depends on factors like square footage, insulation, number of windows, and local climate. A professional load calculation ensures your system is properly sized for comfort and efficiency. Oversized or undersized units can lead to higher energy bills and uneven temperatures.

“We were having issues with our heat and Matt came out promptly to look at everything. He spent as long as it took to figure out the problem and make a diagnosis. He was honest, polite and very thorough. You can tell he really knows his stuff!! Ethan also did an excellent job installing the new furnace and going over everything in detail to make sure we understood how it worked and why he did certain things the way he did. They are an amazing team with excellent service and we truly appreciate each of them! Thank you!!”
