What size HVAC system should I have?

The only way to know the right size for your home or office is by having a licensed professional evaluate your heating and cooling needs and recommend an HVAC unit for you.

AC and Heating Maintenance

What maintenance should I do for my AC?

How often should I change my filters?

For the best filtration, we recommend that you change your filters at least once a month. For the units with washable filters, you should clean them once a month.


What is the purpose of an air duct?

Air ducts are responsible for distributing cooled or warmed air throughout your home. Without ductwork, there would be no point in installing an HVAC unit. Properly designed and installed ductwork saves you a great deal on energy costs, and helps prevent premature failure of your HVAC system.

How do I tell if my ducts are leaking?

There are many ways to tell if your ducts are leaking. You can tell by finding certain rooms in your home never reach the desired temperatures. However, the best way is to contact a professional to help you assess the performance of your ductwork.

How do I fix leaking ducts?

Unlike most people believe, the best way to repair your ductwork is not by using duct tape. Contact a trained professional to properly seal your air ducts and reduce energy costs.
