Commercial HVAC Repair FAQs
How often should our commercial HVAC filters be changed?
In a standard office environment, filters should be replaced every 3 to 4 months.
How long does a typical commercial HVAC system last?
Most commercial systems (like RTUs or Split Systems) have a service life of 15 to 20 years, while well-maintained boilers and chillers can last 25 years or more. Regular preventative maintenance is the single most important factor in reaching the upper end of that lifespan.
What is a “Preventative Maintenance Agreement,” and do I need one?
It is a scheduled service plan (usually quarterly or bi-annually) designed to catch small issues before they become expensive emergency repairs. For commercial entities, these agreements are essential for budgeting, as they stabilize energy costs and extend equipment life.
Our energy bills are spiking. Could the HVAC be the culprit?
Most likely. HVAC systems typically account for 40% to 60% of a commercial building’s energy use. If your bills are rising, it could indicate a refrigerant leak, failing compressor, or clogged coils that are forcing the system to work harder to maintain temperatures.
What is the “ideal” temperature setting for an office?
While “comfortable” is subjective, OSHA and ASHRAE generally recommend a range between 68°F and 76°F (20°C to 24°C).
What commercial HVAC brands do you repair?
We service all makes and models of commerical HVAC equipment.
What is the difference between MERV ratings?
Minimum Efficiency Reporting Value (MERV) measures how effectively a filter captures particles.
What should I do if I see water leaking from my rooftop unit?
Shut the unit down and call for service. This is usually a sign of a clogged condensate drain line or a cracked drain pan. In a commercial setting, this can quickly lead to ceiling damage and mold growth if not addressed immediately.
Why is one area of our building freezing while another is too hot?
This is usually a zoning or balancing issue. It could be caused by a stuck VAV box damper, blocked vents, or a thermostat located too close to a heat source (like a copier or direct sunlight). A professional air balancing report can identify where the flow is being restricted.
