Heating Service in Concord

If you want your Concord home to stay warm and toasty without breaking the bank, you've come to the right place. We offer gas furnaces with extremely high Annual Fuel Utilization Ratings (AFUE), and variable speed fan motors for quiet, efficient comfort. For even greater efficiency, a hybrid heating system uses a high efficiency gas furnace and electric heat pump to provide optimal energy usage throughout the heating season. We not only offer new furnaces and heat pumps, but we provide seasonal maintenance and emergency repair work for any make and model of equipment.

Furnace Repair & Maintenance

Maintaining your HVAC system is very important if you want it to run efficiently, and last as long as it was manufactured to last. A neglected heating and air conditioning system might work for you each season, but it will begin to lose efficiency, and can have premature problems, costing extra money to repair. Stewart's seasonal maintenance plans are low cost ways to ensure your HVAC system is running at peak performance. We will clean and inspect your equipment for smooth operation.

If your indoor comfort system system is not functioning correctly, our experienced technicians can help. We will quickly arrive and diagnose the problem so you experience as little down time as possible. Our extensive knowledge and experience in the HVAC field means we know how to quickly find the real problem with your system. This saves you the extra time and expense associated with lack of experience and poor troubleshooting. Once the problem is determined, we will give you our recommendations on the best action to take for your specific situation.
