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

Monday, 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.

Monday, August 17th, 2020

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.

We’ll dispel some of the mystery around this term and explain why it’s important for your AC installers to know the exact tonnage necessary for your facility.

What Rating Do You Give Your AC for Its Summer Report Card?

Monday, September 16th, 2019

checkmark-greenOh no, report cards already? And you may not even be enrolled in school currently! Don’t worry, you’re the one giving the report card, and you don’t need to be a credentialed teacher. You only have to be the owner of a central air conditioning system who has paid attention to the AC’s performance over the summer.

We recommend taking time at the end of summer to give a grade to your air conditioning system. This gives you an opportunity to think about whether you’ll need to replace the air conditioner in the near future or if it requires repairs before it shuts down for the winter. Repairs are always a priority for an AC, no matter the time of the year. It pays to stay on top of repairs, because leaving the air conditioner to sit for the winter with a lingering problem often means running into a worse problem later.

Anyway, on to the grading.

How a UV Air Purifier Can Help Your Home

Monday, July 8th, 2019

UV-lightIn terms of comfortable living, most homeowners are going to think first and foremost about temperature. This is totally understandable. Without an effective air conditioner in the summer and a reliable heater in our relatively mild winter season, it is very difficult to live in anything even remotely resembling “comfort”. If you think that temperature is the only factor to consider when it comes to your comfort or to your overall quality of life in your home, however, think again.

You should be equally concerned with the indoor air quality in your home, if not more so. Why? Because subpar indoor air quality can actually have pretty serious implications for your health. Your comfort is very important, of course, but your health needs to be protected at all costs. That is why you may need to use a UV air purifier in your home. If you are curious about UV air purifiers, this is the post for you, courtesy of your trusted HVAC company in Durham, NC.

Short-Cycling: Why It’s Bad News for an Air Conditioner

Monday, August 20th, 2018

air-conditioning-condensers-near-plantsOne of the most common and harmful troubles an air conditioner can encounter is a condition called short-cycling. It’s both a symptom of a problem and a problem itself. Although sometimes a few simple adjustments may fix short-cycling, if the root cause is serious it requires a professional HVAC technician to do the repairs. Unless short-cycling is stopped, it will eventually lead to an early replacement for an air conditioner and waste enormous amounts of power until then.

The Brutal Facts of Short-Cycling

The phrase short-cycling is HVAC-speak for when an air conditioner (or heat pump) becomes caught in the start-up cycle and turns on and off repeatedly without completing the cooling cycle. Under normal conditions, an AC powers up the compressor and runs until the thermostat registers it has met the temperature request. The AC then powers down the compressor. A short-cycling AC will prematurely stop the compressor before the end of the cooling cycle, and then start up again a short time later. When the compressor is turning on and off multiple times an hour and the compressor runs for less than 15 minutes at a time, the AC is short-cycling.
