Good HVAC maintenance is critical for maintaining comfortable, energy-efficient, and cost-saving commercial buildings. As a seasoned HVAC technician, I’ve seen how quickly minor lapses can escalate into complete system breakdowns. In this guide, I’ll take you through the most frequent commercial HVAC maintenance gaffes — and how to sidestep them.
1. Forgoing Regular Inspection and Tune-Ups
Why it matters: Regular inspections are your best defense against breakdowns. Without them, little problems get ignored until they lead to major — and costly — issues.
Pro tip: Have professional inspections done seasonally, preferably in spring and autumn, to ready your system for peak heating and cooling months.
2. Neglecting Filter Changes
Why it matters: Dirty or plugged filters decrease airflow, making your system work harder. Not only does this increase energy expenses, but it also impacts indoor air quality.
Pro tip: Change or clean HVAC filters every 1–3 months, based on usage and filter type in your system.
3. Ignoring Ductwork Maintenance
Why it matters: Out of sight, out of mind — but leaks or disconnections in ductwork can seriously cut efficiency and even out heating or cooling.
Pro tip: Get your ductwork checked regularly and seal up any gaps to avoid energy loss and keep the air flowing evenly throughout your building.
4. Mismanaging Thermostat Settings
Why it matters: Inefficient use of thermostats can put undue pressure on your HVAC system and push up your utility bills.
Pro tip: Use a programmable or smart thermostat to optimize settings by season, occupancy, and time of day. Ensure it’s calibrated correctly for accurate readings.
5. Ignoring Unusual Noises or Odors
Why it matters: Strange sounds or smells are often early warning signs of mechanical problems or electrical issues.
Pro tip: Don’t ignore warning signs. Schedule a professional inspection immediately if your system is making abnormal noises or emitting strange odors.
6. Not Purchasing a Maintenance Agreement
Why it matters: Some companies skip maintenance contracts to save money — but the truth is, consistent servicing avoids expensive breakdowns and lengthens system lifespan.
Pro tip: Partner with a reputable HVAC company for a customized maintenance plan. This keeps your system operating optimally and puts you on top of future issues.
7. Trying DIY Fixes
Why it matters: Commercial HVAC systems are sophisticated. Do-it-yourself repairs may actually harm them and can even invalidate manufacturer warranties.
Pro tip: Let certified professionals do the repairs. It’s safer, more effective, and in compliance with warranty and safety regulations.
Take Care of HVAC Maintenance to Safeguard Your Investment
Avoiding these common mistakes is key to keeping your commercial HVAC system in peak condition. With regular professional maintenance, you’ll benefit from improved efficiency, reduced repair costs, and a longer system lifespan.
Most importantly, remember this: Your HVAC system is mission-critical for occupant comfort, productivity, and health. Don’t take chances — team up with a professional HVAC partner to stay ahead of issues and keep your building operating at peak performance.
