Frequently asked questions

Question

What types of furnace filters are best, and how often should I change it?

Filter changing depends on the type and the thickness. It is highly recommended to replace any filter that is only 1” thick every 30 days. Thicker filters such as a 4” thick filter can last from 6 months to 1 year and typically do a better job of filtering.

Question

When do I need a system tune-up?

When was the last time your system was inspected? Older furnaces can potentially have issues with their heat exchangers. As the seams weaken they begin to crack, allowing carbon monoxide to be released into the air that your family breathes. This odorless, tasteless gas is not safe. The drain systems and other safety switches also need to be checked. These parts can become plugged with by-products from natural gas or propane. Older A/C systems can develop leaks that can cause the freon to escape after a long winter season, and temperature changes can emphasize this problem. All manufacturers recommend yearly maintenance to maintain your equipment warranties. Get in touch to have us properly inspect your system and keep your family safe all year long.

Question

What does an ultraviolet purification system do?

Unlike a standard filter or air cleaner that only traps particles, a UV system actually kills them by sterilizing the live particles in the air stream so they can't reproduce. As these viruses or allergy-causing microbes are destroyed, they are then trapped in the filtration system.

Question

Do you offer maintenance plans?

Absolutely! We offer annual and bi-annual maintenance memberships. If you would like to schedule a maintenance, give our office a call and we can add you to our calendar. In addition, residential members never pay a dispatch fee (during normal business hours) and get discounts of service calls and installs! We'll contact you to schedule each season. Payment is made up front to cover the whole year.
