A/C Troubleshooting Guide

Updated: 5 days ago

The last thing you want to learn once the temperatures start to rise is that your air conditioning unit isn't functioning correctly. By checking your heating and cooling units ahead of peak season, you're taking steps to ensure faster service from your preferred HVAC company.


If you are unsure whether your heating unit requires prompt attention, here are some AC troubleshooting tips to help you determine if calling a professional is recommended.


Properly Set Your Thermostat - In some cases, repairing your air conditioner only requires you to set the thermostat in your home correctly. An incorrectly set thermostat can result in your unit not working the way it's supposed to. If you have the unit set to heat, don't be surprised when hot air starts blowing - and don't assume a broken AC unit, either.


Replace The Batteries In Your Thermostat - Drained batteries in your thermostat can impact how effectively your HVAC system works. When batteries are dead, the wall unit breaks communication with the outdoor unit, causing temperature irregularities. Depending on the thermostat you have, batteries may last anywhere from a few months to up to five years. If you're unsure of how old your cells are, a battery tester can tell you how much juice they have left.


Check Your Air Filters - Air filters play a significant role in the performance of your HVAC unit. Clogged air filters block the free flow of intake air, which degrades the overall air quality and temperature levels in your home. A clean air filter is likely to improve the functionality and performance of your HVAC system.


Inspect Your Air Vents - Much like your air filters, blocked air vents might also contribute to degraded performance. Check to make sure dirt and dust aren't blocking them, and all vents are open.


HVAC Issues That Require Professional Repairs


In some cases, your cooling system could require an HVAC company to complete repairs. If any of these circumstances apply, contacting an HVAC professional is in your best interest.


Unexpected Noises - A properly functioning HVAC unit operates quietly. If you notice unusual or unexpected noises such as whistling, buzzing, or whirring, an HVAC technician can source the cause of the noise and make needed repairs to get it to stop.


Abnormal Odors - When your air conditioner isn't working correctly, humidity indoors rises. During the summer season, increased humidity contributes to the formation of mildew, musty smells, and mold. Other unusual smells, including rotten eggs (natural gas) or a burning odor during winter months, call an HVAC professional and leave your home immediately.
