Frequently Asked Questions
What is the average life of a commercial AC unit?
A well-maintained commercial HVAC system typically lasts 15–20 years, with rooftop units and chillers averaging around 15 years, and individual components like compressors lasting 8–10 years. Regular filter replacement, coil cleaning, and preventive maintenance—services DTM offers—can help maximize that lifespan.
Why is my commercial AC not working?
Commercial AC failures can stem from numerous issues:
Refrigerant leaks or low refrigerant levels
Faulty compressors, motors, or fan assemblies
Dirty coils or clogged filters reducing airflow
Thermostat or control board malfunctions
Electrical issues, such as failed capacitors or breakers
What is the 20 rule for air conditioners?
The “20‑degree rule” advises not to set your thermostat more than 20 °F below the outdoor temperature (e.g., if it’s 95 °F outside, don’t set below 75 °F). Going beyond this puts excessive strain on your system, reduces efficiency, and may shorten its lifespan.
Why is my AC fan on but not cooling?
If the fan runs but there’s no cooling, common causes include:
Low or leaking refrigerant – not enough coolant to absorb heat
Compressor failure – refrigeration cycle isn’t running
Reversing valve stuck (in heat pumps) – system stuck in heating mode
Frozen evaporator coil – airflow blocked
Thermostat short or misconfiguration
What is the minimum SEER rating in Texas?
In Texas, the legal minimum SEER (Seasonal Energy Efficiency Ratio) for newly installed central AC systems is 15 SEER—equivalent to approximately 14.3 SEER2. For energy efficiencies beyond compliance, DTM can help you explore higher-SEER options to match budget and performance needs.
What is the most reliable AC unit brand?
Based on industry reputation for durability, efficiency, and serviceability, popular brands include Carrier, Trane, Lennox, Rheem, Goodman, Daikin, and American Standard. DTM recommends matching the right brand to your facility’s size, budget, and maintenance capabilities—while focusing on regular upkeep to boost reliability over time.
