3 Things to Check Before Calling Your AC Experts



With the onset of spring and summer also comes the time when your home or office’s central air conditioning system becomes a necessity. It’s a modern convenience we Floridians cannot live without. However, we’ve all been there… stuck in our home or office sweating beside a malfunctioning air conditioner. And the thought of calling a technician for repairs may be a scary thought for some. Fortunately, Blair’s Air Conditioning and Heating is here to help with five things you should definitely check before calling in for professional backup.

#1 Appraise Your AC Air Filters


One of the most common causes your air conditioner freezes up is due to blocked or restricted air flow. The culprit is almost always a dirty air filter. When there’s no air moving through your central AC system, the condensate on your evaporator coil isn’t able to function properly, causing your unit to freeze up.

Set reminders to regularly clean or replace your air filters, or schedule routine maintenance with a professional who can take care of the task for you. You’ll also want to check that your indoor air handler isn’t being crowded or obstructed by furniture or other objects.

The Risks of Not Changing Your Air Filter

  • Dirty air ducts and poor indoor air quality (IAQ)
  • Reduced air flow and high energy bills
  • Cooling inefficiency due to frost buildup on your evaporator coils

#2 Check Your Thermostat

Sometimes, the solution to a malfunctioning air conditioner can be as simple as checking your thermostat. Make sure the settings are adjusted for your desired comfort level and ensure the batteries are good if your thermostat is battery-powered. It’s also a good idea to clean the exterior and behind the face of your thermostat to rid it of dirt and dust.

If you’re playing yoyo with your home’s temperature, this could cause your AC compressor to overheat and lead to an entire system shutdown. Set your thermostat to the desired temperature and wait for it do adjust accordingly. If it doesn’t reach the set temperature, you may want to call in for professional advice and assistance.

#3 Inspect the Condensate Drain Line


Your condensate drain line is an essential component in ensuring the continued operation and efficiency of your air conditioning system. If you notice a puddle of water in your drain pan, located next to your outdoor condenser unit, this is a sign that the condensate drain line is clogged.

Condensate lines can become clogged with debris and buildup including mold, algae and other unwanted items. It’s crucial you maintain and keep your AC drain line clean to prevent system breakdowns, avoid repair expenses, and protect your home’s indoor air quality.
