Maintaining Your Air Conditioning Unit in McHenry County

Is your A/C unit not cooling your home? It may be time for an annual checkup and maintenance.

Here at WeatherWise Heating and Cooling, we understand the value of regular maintenance of your cooling system. When you use your A/C system for multiple months at a time, the air filters become clogged, which blocks airflow and reduces the efficiency of your air conditioner. 

Neglecting A/C maintenance is proven to cause a decline in the performance of your A/C unit, along with an increase in energy use, an increase in your air conditioning bill, and possibly additional HVAC repair costs down the road. On the other hand, regular maintenance of A/C units improves air quality in your home or business, improves performance of your A/C system, and extends the life of your unit. For this reason, we recommend routine HVAC maintenance checkups every six months. So call today for more information on how to keep your cooling system running calm, cool, and collected.

Check out our 4.9 star Google review ratings from past customers who have had new installed and replaced furnace systems with us. We work with the best manufactures to ensure quality heating systems at the best price. Our team of experts will provide several models to meet your needs.
