Commercial HVAC Maintenance Contract
Your HVAC equipment is a vital part of your building's indoor air quality, yet it is often taken for granted. Much like an automobile, it needs regular maintenance to provide you with maximum comfort, efficiency and reliability. With our maintenance agreement, you will enjoy these benefits for an affordable annual fee.
Reduced Monthly Energy Costs
A properly maintained system can operate up to 20% more efficiently than a dirty, neglected system. With the gas and electric rates continually on the rise, we could all use a savings.
Priority Service
As an agreement customer, you will receive quicker response time if your system requires emergency service. This is especially important as there is a growing labor shortage in our industry.
Convenience
You don't have to keep track of when your HVAC equipment is due for maintenance. Whether you prefer quarterly or semi-annual service, it is set up on an automatic schedule to be completed per your request.
Extend Equipment Life
Like most things, your HVAC equipment will last longer if it is properly maintained.
Scheduled Inspections
We will provide a qualified service technician to inspect your HVAC equipment for proper operations to ensure it is in top working order for the upcoming cooling or heating season. Maintenance inspections will be performed during normal business hours Monday-Friday, 7:30a.m. - 4:00p.m.
