Late Summer vs. Your Air Conditioner: A Few Things to Know

August 31st, 2020

thermometer-going-redHot weather is hot weather as far as your air conditioning is concerned—or at least this is what most people think when they think about their AC system at all. The air conditioner does its job as well as it can against the heat.

But this isn’t 100% true. An air conditioner is like any complex appliance: it starts to wear down with use, and changes in external conditions can make it more difficult to do its job and put it at higher risk of failure. This is the situation most air conditioning systems are in during the late summer. This is a time of year when we caution our customers to be on the watch for signs they need Durham air conditioning services. Just because fall is around the bend doesn’t mean you can relax about the performance of your air conditioner. Below are some key facts to know about this time of year.

industrial-acsWhen you are looking to install an air conditioning system for your building, or to replace an older air conditioning system, you’re going to see the word tonnage referenced often. “What tonnage of system do you think you’ll need for the space?” That sort of thing. It’s standard HVAC lingo, and most people outside of the industry don’t know its specific meaning, except that bigger tonnage has something to do with more cooling power.

If I Have Air Filters, Do I Need an Air Purifier As Well?

July 6th, 2020

pleated-air-filterYou’re concerned about the indoor air quality of your home. Many people are right now, since we’re spending much more time indoors and the summer won’t change that. So along with a reliable air conditioning system (which we can help you with), you’ll also want to know you have clean and healthy air to breathe indoors.

Let’s take a look at air purifiers in Cary, NC and when they’re useful.

What Counts as a Good SEER Rating?

June 22nd, 2020

air-conditioner-money-saverWe’ve talked about air conditioning efficiency ratings before because they’re one of the first things people look for when considering the purchase and installation of a new air conditioning system. When you think of “energy efficiency,” you usually think of “money savings,” and you may be willing to pay for a more expensive air conditioning system if it rewards you with many years of lower-cost cooling performance.

But choosing an air conditioner based on the energy efficiency rating is trickier than it looks. The most efficient system may not be a cost-effective purchase. It may not even be the right system for your home. The efficiency of a cooling system only matters if the system can work at peak performance, and this is why we strongly recommend the you call our professionals when you plan for new air conditioning in Rolesville, NC.

Why Your AC’s Fans Aren’t Working

June 8th, 2020

There are many parts of an air conditioning system that are essential for it to work. If the compressor dies, the AC won’t run, for example. Today we’re going to look at one part—that is actually two parts—that can often fail during a summer season and leave a home without cooling: the fan(s). Specifically, we’re going to see why your fans might stop working and trap you in a boiling home.

Is Your AC’s Compressor Going Bad?

May 25th, 2020

compressor-in-ac-unitThe compressor is the part of your home cooling system that allows it to actually cool. Without the compressor, the refrigerant in the AC wouldn’t be able to change between liquid and gas form, releasing and absorbing heat as it does so. It also wouldn’t be put under pressure so it would circulate. If you don’t have a working compressor in an AC, you don’t have an AC.

There are other vital parts of an air conditioning system, but a failed compressor is perhaps the most expensive to fix. So much so that people often find it more cost-effective to replace the air conditioner entirely rather than pay to replace only the compressor.

Can My AC Handle Summer Humidity?

May 11th, 2020

too-much-heatIf you’ve experienced at least one year living in the Triangle, you know that high humidity makes heat much harder to cope with. You can expect to run your home’s air conditioning system longer and harder to overcome the additional heat.

Well … the feeling of additional heat. High humidity doesn’t raise the temperature of the air: an 85°F day is still an 85°F day no matter if the relative humidity is 15% or 90%. What happens when humidity levels are too high (over 60%) is that more heat becomes trapped inside your body. The increased moisture in the air slows down your ability to release heat through perspiration, so you end up feeling hotter than if you were able to shed most of that internal heat.

Basic science lesson over. What does this have to do with your air conditioner? Plenty. If you feel your air conditioner isn’t doing much to combat the high humidity in your house each summer, that’s because it ­wasn’t designed to.
