Most people don’t know much about their air conditioning unit until it breaks down; then they have a lot of questions! If you’re one of those people, or if you want to learn more about AC repair, read on. This post will answer some of your most common questions.

What are the signs that you need AC repair services?

One of the first signs that you need AC repair is hearing a sound that isn’t normal for your HVAC system. A system that is running properly may make a buzzing or humming noise. If it starts becoming louder or you hear rattling, hissing, or whistling, then you should contact Frederick Air for a diagnostic. It’s better to fix the problem before your system completely gives out and you’re left in the summer heat without air conditioning. [Read More: What do the noises from my HVAC system mean?]

Another sign is that you have to continuously turn down the thermostat in order to feel comfortable in your home. That means your system cannot keep up with the demand, which could be a sign that it needs maintenance.

How can you tell if the issue is with your AC unit or with your thermostat settings?

It’s relatively easy to diagnose whether the issue is with your AC unit or your thermostat. First, remember the twenty-degree rule if it’s an extremely hot day outside. Perhaps you don’t have a problem at all! Your system might temporarily have a hard time keeping up with the weather.

If you’re all clear with the 20-degree rule, look at the temperature setting on your thermostat and see if the home is also close to the requested temperature. If it’s more than five degrees off, check if there is a door or window open that is letting out the conditioned air. Does everything seem normal? Then it’s time to book an appointment with Frederick Air.

Can a dirty air filter cause an AC unit to break down prematurely?

Absolutely! A dirty air filter makes it impossible for your system to generate proper airflow. We stress the importance of changing your air filter regularly and have several options available if you would like us to handle it for you during your maintenance visit.

What should you do if you notice water leaking from your AC unit outside your home?

A little bit of water under your outside unit is normal, especially in Frederick, Maryland, where it can be extremely hot or humid weather. If it continues to drip excessively even when it’s not relatively hot outside, give us a call and we will come to check it out for you.

Are there any preventative measures homeowners can take to avoid costly AC repairs in the future?

Change your air filter regularly. Most air filters should be changed every three months, but there are newer systems that have a six-month filter. [Read More: The Importance of Changing Your HVAC Filters]
