Signs Your St. Louis Business Needs HVAC Repair
When running a business and it can be easy to forget the maintenance needs of your building. The last thing you want to run into is your HVAC system failing and causing discomfort for you and your employees. But, how do you know when you need to repair the HVAC unit? Below we have a few signs to look for in order to avoid your HVAC completely failing.
- Energy Increases -
If you notice your energy bill has increased dramatically month over month, this could be an indicator that your HVAC unit is in need of repair. The energy increase is most likely due to your HVAC system having to work twice as hard to provide the same level of comfort to your business while also using twice the amount of energy to do so. - Strange Smells -
Another indicator that your commercial HVAC unit may be experiencing problems is if you notice an odd odor coming from the vents of your HVAC system. Often the ductworks in your building can be the place where mold or mildew grow. It could also be a dirty air filter that needs to be replaced. But, if you notice a burning smell, you should contact our professional team right away to come and inspect the HVAC system. - Temperature Control Issues -
Have you noticed that your office building stays at the same temperature no matter how high or low you crank the thermostat? It could be a thermostat issue or a stuck damper that needs attention. Contact us today for the help you and your business need.

Just hired Martin-Jetco to install a new AC system. Sales Manager Douglas met with me and reviewed my options. He was very nice, knowledgeable and honest about my quote. Gave me a few options and explained everything. The installers were also very nice and took care of everything with no mess. I got 4 other quotes and these guys are super competitive on price and transparent. Solid work.- Colin D.

I spoke to a technician over the phone to try and troubleshoot some problems I was having with a reverse polarity code. Nothing was working. Not soon after, Chris shows up. Does a quick diagnostic and finds my board is fried. He leaves to gather material and is back quickly to install the new board. As most might know, once you fix one problem...you find another. Chris made some quick adjustments and got me running some heat in this house so my dog doesn't freeze to death. Thanks to Eric, Doug and Chris for all that you do. And those nice people in your office, who are always so understanding and helpful.- Cory A.
