Thiele’s certified technicians can repair all types of furnaces, boilers, heat pumps, and heating systems. We have one of the most extensively trained service departments in the industry. Our technicians can even offer expertise on some of the oldest equipment out there! Out of respect for you and your home, our installers will always wear shoe booties and lay down carpet runners to protect your floors from dirt and debris.

Furnace Repair


We use only the best materials, equipment, and installation techniques. Why? Because we want to ensure your new HVAC system is safe and functioning at its highest capacity. Our craftsmen even can create custom ductwork and fabricated metal parts for any heating system need. Installing a new HVAC system can mean improved efficiency and lower energy bills.

Thiele’s Preventative Maintenance Program

Through our preventative maintenance program, we will perform two comprehensive maintenance checks a year – one in the spring and one in the fall. We’ll check and adjust airflow temperature and clean air filters (or replace, if necessary). We also check the thermostat’s operation, clean coils, and clear debris from the condenser unit. Members of our preventative maintenance program can also receive a 15% discount on any necessary parts and repairs, even during the current service call.
