Should You Repair or Replace Commercial HVAC Equipment?
Age alone doesn't decide it. The U.S. Department of Energy's Better Buildings program treats a rooftop unit as near the end of its useful life when it no longer keeps the space comfortable, the chance of failure is high or maintenance costs keep climbing. We weigh the same things when we help you decide. These are the signs that point toward replacement:
- Repairs keep coming back. Service calls are getting more frequent and the bills keep adding up.
- The space isn't comfortable even when the unit runs.
- A major part has failed on an older unit, such as a compressor or a heat exchanger.
- It uses R-22 refrigerant. R-22 systems can still be serviced, but the refrigerant is no longer produced and its price is likely to rise as supplies run down.
- Energy bills are climbing without a change in how you use the building.
The Department of Energy notes that emergency rooftop unit replacements often cost much more than planned ones. Planning ahead lets us order the right equipment, arrange lifting and permits where they're needed and schedule the work at a time that suits your business.
Frequently Asked Questions About Commercial HVAC Services
A typical maintenance visit includes changing filters, cleaning coils, checking refrigerant charge and airflow, inspecting belts, motors and electrical connections, and testing controls.
At least once a year. ENERGY STAR recommends a yearly tune-up, and checking filters every month and changing them at least every three months. Equipment that runs long hours or serves a commercial kitchen may need attention more often. We'll tell you what your equipment needs.
Commercial equipment is usually larger, is often a packaged unit on the roof, may serve several zones or tenants and runs longer hours than a home system. That means more wear, more frequent maintenance and technicians who know commercial equipment. Many smaller buildings use split systems and furnaces much like a home, sized for a business.
Yes. The EPA allows existing R-22 equipment to keep running and to be serviced. R-22 is no longer produced, so repairs depend on recovered and reclaimed refrigerant, and the EPA expects its price to rise as supplies are used up. If your system needs refrigerant often, compare the cost of ongoing repairs with the cost of replacement.
It depends on your lease. Under a triple net lease the tenant usually handles maintenance and repairs, but who pays to replace a unit depends on how the lease is written. If you and your landlord need to agree on a repair or a replacement, we can look at the equipment and explain its condition to both of you.
It depends on the equipment, how many units you have and whether the work is a repair, maintenance or a replacement. We price it after looking at your equipment, so the quote reflects your building rather than a rough guess.
