It depends on the age of the unit, the cost of the repair and how often it has broken down. A single small repair on a newer system usually makes sense. Repeated repairs on an old one often point toward replacement. We can look at your system and explain the options. ## Heating and cooling for businesses We work on commercial properties as well as homes.

Most manufacturers recommend a yearly checkup for each system. Many people have the AC looked at in spring and the furnace in fall, before heavy use. Regular service helps catch worn parts early. Why is my AC running but not cooling the house? Common causes include a dirty air filter, a dirty outdoor coil, a thermostat problem or low refrigerant from a leak. Check the filter first. If the air is still warm, turn the system off and call us so a technician can find the cause. What can help with dust, allergies or humidity in my home? Clean filters, properly sealed ductwork and indoor air quality equipment can all help, depending on the problem. We install indoor air quality products, so call us and describe what you are noticing. Do you work on both homes and businesses? Yes. We serve residential and commercial customers in the Middletown area. How do I schedule service or request a quote?
