Dave's Heating & Cooling - Greencastle's Experienced HVAC Services

We recommend scheduling professional maintenance twice a year—once in the spring for your cooling system and once in the fall for your heating system. This regular service helps prevent common local issues like clogged air filters and ensures your furnace and air conditioner run efficiently, which is especially important with our Indiana seasons. As a local company since 1986, we offer maintenance plans to keep your system in good shape and help avoid unexpected repairs.

First, check if the thermostat display is on and try replacing the batteries. If it's still not responding, check your home's circuit breaker to ensure power is reaching the unit. These simple steps can often resolve minor thermostat issues common in our area. If the problem persists, our team at Dave's Heating & Cooling provides 24/7 emergency repair services. We can diagnose and fix thermostat malfunctions or recommend a replacement to restore comfort to your home quickly.

Our installation service is a comprehensive process. We start with a consultation to assess your home's needs and recommend the right system for efficiency and comfort. Our licensed technicians handle the full installation, including proper sizing, ductwork evaluation, and connection, with attention to local building codes. We also provide guidance on operating your new system. Serving Greencastle, IN since 1986, we ensure your installation is done correctly for reliable performance year after year.
