One of the best ways that you can lower your utility bills and extend the life of your system is to have a yearly tune-up.  We recommend a spring tune-up for you cooling system and a fall tune-up for you heating system. This will not only improve how efficient your systems run but how comfortable you are.

We also recommend that you check your filter each season.  This is particularly important to do during the summer and winter.  If your filter is dirty, then your system is working harder than it needs to in order to keep your house warm or cool.  Dirty filters lead to dust and dirt building up in your system which can cause your system to fail sooner than it should.  We carry an array of filter sizes and merv ratings can give you a quote for a supply that you can keep on hand.

Precise Air Systems does offer Extended Warranties on all its installations for both labor and/or equipment.

Service technicians during a routine safety meeting


Air flow is crucial in cooling or heating please be sure to replace your filters or sign up for a routine cleaning & filter replacement. Here is an example of a clogged filter versus a new filter. Air needs to flow through the filter & if the filter is blocking this from happening then it may cause damage to your system & is very inefficient.
