INDOOR AIR QUALITY SOLUTIONS IN HAGERSTOWN & FREDERICK, MD



Air quality is an issue for many homeowners for a number of reasons. While normally things like dust and pet dander would be nothing more than a mild annoyance, they can become real issues in homes where family members suffer from allergies or asthma, or when the home has little or no air circulation.
If you live in the area and indoor air quality is an issue in your home, call the experts at Larry & Sons today to learn more about our comprehensive air quality testing and air cleaner and purifier installation services. We can help you choose a system that will provide the necessary protection for your family members against common allergens.
Air Quality Inspections
If you have air quality issues in your home, the first step is to have it tested. We can visit your home and inspect it, then recommend exactly how best to respond. Depending on our findings, it may be recommended that your filtration system is upgraded or an air cleaner is installed.
We offer installation and replacement services for all major types of indoor air quality systems in Hagerstown, MD, and can provide ongoing repair and maintenance services for those homes that require it.
Air Filters and Air Purification Systems
There are several possible allergens that can build up in your home’s indoor air. The most common of these are pet dander, pollen, dust, and other household debris. They generally only mildly irritate people with allergies, but if there is little or no ventilation irritation may increase. An air filtration device or purification system may be right for your Hagerstown home. Our indoor air quality professionals can make recommendations on the best choice to reduce irritating allergens in your home.
UV Air Purifiers
Another option to consider is installation of an electronic air cleaner. These systems can ionize the air and remove smaller particles like exhaust and smoke. UV light systems will keep germs like bacteria and viruses and humidity control systems will actively manage humidity levels in your home, so it does not get too damp or too dry.

Just bought my house literally a week ago and have already met 3 of your wonderful technicians (2 heating and 1 plumbing). They are polite and personable, and I feel like I can trust that they are doing what is best for my home… not just for the company’s bank account. That is difficult to find in any type of Service Company. Thank you!
Josh was wonderful. We just bought a house that needs a lot of work, and the heating systems were no exception. He looked everything over and gave me several options for the amount of work that needs to be done. I felt he was honest and sincere in his diagnosis of my many issues, and in trying to figure out the best options, while still remaining economical. He was very polite and personable as well. Thanks Josh!
