Commercial Preventive Maintenance Agreements

Heating and cooling systems have a way of breaking down when the weather is at its worst; on the coldest day of a frigid winter, or during a sizzling summer heat wave; times when your comfort system must work the hardest, and when you need it most.

Regular check-ups will help to maximize the life expectancy of your system; unfortunately, even the best maintenance won't prevent normal wear and tear.

Please contact us to discuss our service agreements in more detail. A representative from our company will come to your location and will recommend a program that best fits your needs.

Your investment in our preventative maintenance agreement includes:

Semi Annual And Quarterly Preventative Maintenance Agreements, or any customized agreement to suit your facility

Having your system checked regularly enables us to keep your unit running as efficiently as possible, which saves you money on your utility bill month after month. These regular check-ups also enables us to catch problems before they lead to a larger problem.

Labor Warranty

All of our labor services are warranted for 30 days. If you have a problem within 30 days of service, there will be no charge to come back out and diagnose the problem. We stand behind our work.

Energy Saving Coil Cleaning

Dirty coils reduce efficiency and cause your unit to work harder, causing parts to wear out faster, and shorten the life expectancy of your unit. Your unit will cost you more month after month on your utility bill if the coils are not kept clean. Test performed by the EPA explain that as little as 1/10th of a centimeter of dirt or dust on a coil could reduce efficiency by 21%.

Seasonal Maintenance

Spring Air Conditioning Start-Up

  • Clean all condenser coils with chemical cleaner and hoses, clean evaporators-brush and wipe down. Clean condensate drain pans. Change air filters and fan belts on all rooftop units. Lube all fan bearings and motor bearings. Perform an operational checkout of cooling modes as per inspection sheet.

Mid-Summer Air Conditioning Check-Up

  • Change all air filters and check operation of all HVAC Units, exhaust fans and change belts as necessary.

Fall Heating Start-Up

  • Change all air filters and inspect belts. On all HVAC Units, check operation of economizer and heating sections.

Mid-Winter Heating Check-Up

  • Change all air filters and check belts on all HVAC Units, check operation of all HVAC Units. Check HVAC exhaust fan.

Maintenance Defined

Air Filters

  • Must be replaced on a routine bases, while maintaining good air quality and proper airflow.

Evaporator Coils

  • Although air filters catch particles, they are not 100% effective; therefore the evaporator coils must be cleaned periodically, keeping efficiency at its best.

Condenser Coils

  • This coil is subjected to the outdoors and requires yearly cleaning to keep its heat exchanging capabilities at its best. A dirty condenser coil can cause high running pressures, high amperage draw on compressor and definitely equipment failure.


  • A bad belt is not one that is necessarily cracked, but a worn belt reduces its grabbing ability as well. Also belts must be periodically tightened and checked to get maximum airflow.


  • Many motors and bearings are considered “permanently sealed”, however many require routine lubrication preventing pre-mature bearing failure.

Condensate Drains

  • A plugged condensate drain means water problems. It causes condensate drain to overflow and water usually finds its way into the building.

General Observations

  • Overview of unit, tighten up loose components-caused by normal unit vibration, check control section.
