Maintaining your HVAC system is critical to maintaining comfortable air quality in your home. Terrace Heating and Air can provide our customers with a routine Maintenance Agreement on your HVAC system. Regular check-ups help to prevent costly repairs or even replacement of a system.

Terrace Heating and Air now offers two options for a maintenance agreement:

Option 1 – Our most popular agreement, our Annual Maintenance Contract includes two cleanings per year, repair parts discounts of 10%, and priority service.

Option 2 – One time clean & service. Under this option, we perform a one-time cleaning and equipment service of your HVAC equipment. You will forfeit the parts discount in the event of an equipment failure and you do not receive the priority service.

Maintaining your system ensure that your HVAC system will run efficiently and will prevent a small problem from becoming a bigger, more expensive problem. Let Terrace Heating and Air service your HVAC system. Contact us to schedule an appointment of receive a quote on our Maintenance Agreements
