How to Tell If Your A/C is Running Efficiently

Now that the summer heat is here, the signs of an inefficient HVAC system become pretty apparent. Whether your A/C has fallen out of its normal routine or you’re just curious, it’s important to know some warning signs to look out for.

When your air conditioner isn’t functioning as it should, you will notice a wide range of differences compared to when it is running smoothly. One major indication of an inefficient HVAC is high energy bills. If you have been noticing that your bills are higher than they should be, the first thing that you should do is check your thermostat in case it accidentally got bumped. If this isn’t the case, your system may be nearing the end of its lifespan. As systems get older, they become less efficient meaning that they need to work harder to cool your home. When your system has to work harder, it will run longer, using more electricity to cool your home. This causes your energy bills to rise, notifying you that it might be time for a new HVAC.

Do you feel like your air conditioner never shuts off? It’s normal for systems to run for about 15 minutes 1-3 times every hour. On days where it is warmer than usual, it may run more often, but it should not be running constantly everyday. If you notice that your system is continuously running throughout the day, it is an indication that it’s not running efficiently. Call your local HVAC professional to examine your system in order to determine if it needs repaired or replaced.

As mentioned earlier, as your HVAC ages, it inevitably becomes less efficient. If your cooling system is 10 years or over and you are noticing that it’s running less efficiently, it’s likely time for a new system.

Lastly, if you are finding that your system needs frequent repairs, it may be time for a new HVAC. Whether it is a strange sound, a weird smell or high energy bills, it is always smart to double check with an HVAC professional. Some HVAC problems can be serious and may require immediate attention.
