Don’t sweat! 5 items to check if your home air conditioning system is not cooling


1.Make sure your air filters are clean and clear of obstructions. If your filters are wet or ice is present at your indoor unit, do NOT operate your system. Call Hamstra Heating & Cooling for service.

2.Check to make sure that your thermostat is set for cooling mode operation and the desired temperature set-point is lower than the current indoor temperature.

3.If your thermostat requires batteries for operation, test them and replace as necessary.

4.If your system has an AquaGuard, or other condensate overflow safety device, check to see if the fault LED light is illuminated. If a condensate safety fault is present, call us for service. This indicates the presence of a drain obstruction which must be cleared prior to operating the system.Image 288

What Our Customers are Saying

My wife and I have been a Hamstra customer for about 8 years, since we moved into a new home. From the beginning we had an extreme amount of problems with a faulty AC unit and Hamstra was there for us every step of the way. Not only did they service and repair our faulty unit but they also installed a new system when it became clear we needed a cost effective solution. We also contracted Hamstra to add an additional wall-mounted AC unit in our office. I can’t say enough about Hamstras commitment to customer satisfaction. It is so rare to find a business with such high standards, dedication and integrity. Every single interaction I have had with Hamstra personnel; including the owner(s), the managers, the technicians and the office personnel, has been a positive experience. I rarely write reviews of a product or service and if I do it is usually to warn others of dishonest business. Because of Hamstras rare, outstanding, commitment to customer satisfaction, they have earned my highest praise. They have gone above and beyond my expectations of a customer. I highly recommend Hamstra to any in need of their services.
