Got Commercial Building Complaints? Blame the HVAC


Owning or managing a commercial building is sure to come with receiving a fair share of
complaints. And while it may be your job to respond and solve tenant problems, taking the
responsibility for such criticisms shouldn’t always fall personally on you. Sometimes you just
need to point your finger at the real culprit: the HVAC system.

HVAC: “What Did I Do?”

We can all probably agree that the heating, ventilation, and air conditioning (HVAC) system has
one job: Keep the commercial building at a temperature that makes everyone happy. But when
it’s not pulling its weight, that’s when problems start to happen that lead to tenant grievances,
such as…
● “It smells funny in here.”
● “There’s a loud clunking noise coming from the air vents.”
● “It’s like an oven, and the air is on full blast!”
● “My energy bills have doubled in the last few months.”
● “There are water stains on the ceiling.”

If these sound familiar, you likely have an HVAC system that needs to up its game.

The Problem with Your HVAC System

If your HVAC system seems to be lollygagging on the job, it may be due to one of the following
1. Old filters: Odd smells and poor air quality may be caused by a dirty air filter. Air filters
trap dust, allergens, and other airborne debris, and should therefore be changed out
monthly to help the HVAC run at its best.
2. Broken parts: If tenants are being serenaded by the sounds of rattling and clacking
metal, it’s possible a part within the HVAC system (such as a fan or duct) is broken,
cracked or loose. Pinpoint where the noise is coming from in order to replace or repair
the part making all the racket.
3. Cracked duct work: If temperature is inconsistent throughout your tenant’s space, it’s
likely an inefficiency in the airflow. This could be caused by a crack or leak in the HVAC
duct work. To fix the problem, you’ll first need to locate the source of the leak.
4. Wrong size: For tenants who are seeing a rise in energy bills or the inability to keep the
space at the designated temperature, it could be because the HVAC unit is the wrong
size. Too big, and the HVAC can’t run as best it can. Too small, and it can’t keep up with
tenants’ temperature needs.
5. Drain line clog: You may think an HVAC is all about air, but water comes into play, too.
Condensation and excess water run through the drain lines, but over time, those lines
can become clogged by dirt and debris. If water can’t pass through, it may start to back
up and leak and lead to water damage in ceilings, behind walls, and on floors.

Maybe the Biggest Problem with Your HVAC System: You

Not one to want to play the blame game, but if you’re pointing the finger at the HVAC, make sure you aren’t the number one problem. While an HVAC system needs to pull its weight, it can’t do so with a lack of maintenance. That’s where you come in. Changing filters, inspecting for wear and tear, and keeping the system clean and cared for is ultimately on you. The good news is you don’t have to go it alone. Skilled professionals are available to help you keeping your HVAC system in tip-top temperature shape. So if you don’t have the know-how or the time (thanks to other commercial building complaints), an HVAC professional can step in to assist.
