It is very important to have your ducts checked regularly. Wear and tear can happen and we live in the desert where the unexpected critter visits happen. Damage to ducks allows air to flow out and not efficiently heat or cool your home. Our Maintenance contract is a good way to have the ducts checked twice a year, as well as your units checked. Remember for the health and longevity of your unit it needs a check-up, much like your car or a person.
