Is Your AC Losing Refrigerant? How to Tell

Monday, April 1st, 2019

air-conditioning-maintenance-technician-checks-mainfoldTo create lower temperatures indoors, your air conditioner uses the circulation of refrigerant, a chemical compound that can easily change between liquid and gaseous forms. As the refrigerant evaporates in the indoor coil of the AC, it absorbs heat and makes the air cooler. Then the refrigerant condenses in the outdoor coil, which releases the heat to the outside. This process is called heat exchange, moving heating from one place to another.

Without refrigerant, an air conditioner cannot carry out heat exchange, and that means no cooling. But that’s not the worst part! Without the proper amount of refrigerant, the entire AC is in danger of failing—usually permanently.

When Even the AC Is Too Hot: Why an Air Conditioner Overheats

Monday, August 20th, 2018

thermometer-going-redWith the weather so hot at summer’s end, everything is in danger of possibly overheating—including your air conditioner. Air conditioning systems are designed to operate in hot weather. Otherwise, they wouldn’t be much use to anyone. But the extra load of work, combined with all the strain and wear the AC has accumulated already during May, June, and July, can cause the motors or other components to overheat.

If your air conditioner stops cooling or its fan breaks, call for a Cary, NC, HVAC contractor to get the issue fixed. Any air conditioning technician worth calling knows all the different reasons why a cooling system might fail toward the end of the summer. Below we’ve listed a few of the most common ones that we see when we’re helping rescue ACs in August and September:

Early Watch for Air Conditioning Repair Signs

Monday, June 12th, 2017

spinng-AC-fanIt’s already hot here in Durham, with temperatures climbing into the 90s during some days—and it isn’t even officially summer yet! We can expect many more blistering hot days to come, especially during July, which is only a month away.

You’ve got your air conditioning system running already, we’re certain of that. If you’ve had the system regularly maintained with annual inspections and tune-ups from professionals before the heat hits, the AC has a good chance of working through the season without encountering major malfunctions or a drop in efficiency. But professional maintenance can’t prevent all problems with an air conditioner, so below we’ve put a list of warning signs an AC may send out during this time of the year that it’s time to call us for air conditioning service in Durham, NC.

When Do I Need to Put More Refrigerant into My AC?

Monday, June 27th, 2016

The above is a question that HVAC technicians sometimes hear from homeowners, and it comes from a common misunderstanding about how air conditioners (as well as other refrigeration equipment) works. People are often aware that an AC uses a chemical blend called refrigerant, or Freon (a trademarked name used for many different blends) in order to supply a space with cooling. But refrigerant isn’t something that needs to be “refilled”—unless there’s a serious malfunction with the air conditioning system, and in that case the only person who should put more refrigerant into the AC is a trained professional who’s licensed to handle these chemicals.

Your AC Can’t Keep Up with the Heat? This Might Be the Reason

Monday, June 20th, 2016

The summer temperatures have arrived, and we can expect to see the outdoor thermometers continue to rise higher into the red as we press on into July. The air conditioning system in your home is probably already getting a good workout from handling the heat and humidity. But is it actually getting the job done that it’s supposed to? If you’ve noticed that the AC is struggling to lower the temperature indoors to the comfort range that you’re accustomed to, there may be a serious problem with the system that will require professional HVAC technicians to remedy.

What to Do When Your AC Stops Working

Monday, May 30th, 2016

Before the big heat of the summer arrives, it’s a smart idea to prepare yourself for air conditioning emergencies. There’s no guarantee that your air conditioner will be able to do its job without malfunctions for the entire summer (although you can significantly increase its chances of being error-free by scheduling spring maintenance from professionals). As soon as you notice any sign that the air conditioner is starting to experience trouble running—such as odd sounds or hot spots around the house—call for professionals to identify the trouble and repair it. The sooner the problem is caught, the easier it’ll be to fix.

No, Ice Appearing on Your Air Conditioner Is NOT Normal!

Monday, May 16th, 2016

One of the more common misunderstandings people have about air conditioners is that the presence of ice is a regular part of how they operate. This is simply not true! Your home’s air conditioner doesn’t use ice during any part of the process of cooling down the indoor air. It uses the circulation of refrigerant to remove heat from the air around a coil inside your house. A blower sends air past this coil, sending the cooled air into the rest of the house.
