Here are a few useful tips from contractors on servicing and maintaining HVAC rooftop units.

According to Steve Moon, Elkton Maryland; “When I think about rooftops, I think of lack of maintenance for that unappreciated soldier sitting up on the roof, all by himself, until he breaks.”

Regularly scheduled maintenance on HVAC units is the only way to ensure the HVAC system is in good running condition.  Sometimes convincing commercial building owners to spend the money on proper maintenance is not always easy, according to contractors.

“The downfall is that packaged units are typically the easiest ones to service, but they get the least amount of service because they’re out of sight,” he continued. “It’s up there, and as long as it’s working, they don’t want to know about it. They don’t want to poke the bear,” says Moon.

Educating commercial building owners is an important factor improvement in rooftop maintenance. Regular maintenance will cost an owner a specific amount, but lack of regular service checks will result in higher cost for business owners.

“The biggest tip is to find clients who are willing to spend the money for a mechanic to do a proper inspection, not a fly by,” said Ronald Sage, vice president of Westside Mechanical Inc.  “If it’s a 130-ton VAV [variable-air volume] RTU [rooftop unit], with an ERV [energy recovery ventilator], Aaon, or a little 5-ton RTU, they all have specific requirements. Each task takes time for a mechanic to do.”

Lack of service education is bad for the consumer as well as the HVAC contractor who may lose work to companies not performing proper maintenance.

One method of making sure that rooftop HVAC systems are operating properly is to make sure the surface they sit on promotes efficiency.

“I have seen the ambient temperature well over 120˚F here in Florida on the roof because of the color of the roof being black,” said Chris Johnson, HVAC sales consultant, Sunrise, Fla.,  “This causes many premature failures that could be prevented if the roof around the rooftop unit is cool sealed with a light-colored coating. Remember design temperature is 95˚ — talk about capacity loss.”

Changing fan belts regularly is another important tip for HVAC systems.
