Commercial HVAC Repair FAQs

What is a typical lifespan of commercial HVAC systems?

The longevity of a commercial HVAC system, while influenced by various factors, typically spans between 10 to 15 years. With consistent preventive maintenance and timely repairs, it’s plausible for commercial furnaces, air conditioners, heat pumps, or boilers to exceed 20 years in service.

Is it worth investing in high-efficiency commercial HVAC systems?

Investing in high-efficiency commercial HVAC systems can yield substantial cost savings in monthly heating and cooling expenses. These systems, compared to regular models, significantly reduce operational costs. Often, owners have found that the initial investment in high-efficiency systems can be recuperated through monthly savings approximately halfway through the system’s expected lifespan.

How often should I schedule maintenance for my commercial HVAC system?

Regular maintenance is pivotal for optimal HVAC system performance and longevity. Scheduled maintenance preserves efficiency, preventing breakdowns and expensive repairs or replacements. We recommend annual maintenance for your commercial system, with frequency tailored to your system’s size and usage. Contact one of our team members for personalized advice.

Is commercial ductwork important?

Commercial HVAC ductwork plays a crucial role in distributing conditioned air within your building. Regular inspection and maintenance are essential as leaks in ducts can result in substantial energy loss and increased expenses. Properly maintaining duct sections and tight connections, sealed with mastic or specialized duct tape, prevents these inefficiencies.

How do you size commercial HVAC systems?

The size of your commercial HVAC system should align with the space’s heating and cooling requirements. An undersized system may overwork and struggle to maintain comfort, while an oversized system cycling on and off frequently leads to unnecessary wear and higher bills. Properly sizing the HVAC system ensures optimal performance without undue strain or inefficiency.
