End of Summer and the Great “Repair vs. Replace” AC Debate

Monday, August 21st, 2017

air-conditioning-repairIt’s already the second half of August, and peeking over the horizon is the official end of summer in September. We aren’t out of hot weather trouble in North Carolina yet, but now is a good time to take summary of your air conditioning system’s performance over the hottest parts of the year and ask the big question: “Is it time to replace the air conditioner in the coming fall, or can I stick with repairs as needed for a few more years?”

Autumn is one of the better times to arrange for an air conditioning system replacement in Zebulon, NC. You’ll have fewer worries about the short period when your house will go without cooling, and you’ll be prepared for any of those fall heat wave surprises. But you don’t want to arrange for an air conditioning replacement unless you have to. The more effective and efficient performance you get from your current system, the better a return on your original investment you’ll receive.

When Do I Need to Put More Refrigerant in My Air Conditioner?

Monday, August 7th, 2017

top-of-outdoor-ac-unitWe’re glad you’re asking this question, because understanding refrigerant and how it works inside an air conditioner is an essential part of understanding when an AC may need to have repairs.

The short answer to “When do I need to put in more refrigerant?” is “Never.” Because

  • you shouldn’t need to replace refrigerant because the AC doesn’t use it up, and,
  • even in the event of a loss of refrigerant because of leaks, you must have licensed professionals handle the job of putting new refrigerant in.

Let’s take a look at both these points to give a fuller answer to the question.

Why Closing Room Vents Isn’t “Zone Control”

Monday, July 24th, 2017

room-ventOne of the services that we’re proud to offer our customers when it comes to air conditioning in Wake Forest, NC is installing zone control systems. With zone controls, you can manipulate temperature levels in different areas of your house separate from one another. There are plenty of benefits to this, such as providing individual comfort for people in your household (no more wrangling over the thermostat when people don’t agree on temperature) and reducing your energy bills by only cooling parts of the home that need it (helpful if you have a guest room).

However, when people hear about the basics of zone controls—dampers inside the ducts shutting off airflow to specific vents—they sometimes wonder why can’t they just do zone control by closing the shutters over the room vents.

There are two good reasons why they can’t: 1) It doesn’t work. 2) It can damage the HVAC system. Let’s take a closer look.

4 Reasons Your Cooling Costs Are So High (Aside from the Heat!)

Monday, July 10th, 2017

piles-of-US-currencyWhen summer rolls into the Triangle Area, people expect to see their electric bills start to rise. Air conditioners can be pretty greedy about using electricity: the compressor that’s at the core of how a cooling system works draws a large amount of amps as it runs. High electric bills are simply part of life during the summer.

But there’s a difference between higher electrical bills—and bills that are absurdly high. If you’ve noticed you’re paying much more to run your air conditioner this summer, and you don’t believe it’s because you’re using it more or the days are hotter, then this post is for you. We’ve put together four reasons your cooling costs might be higher and what you can do about it.

Ice on the Air Conditioner: No, It Shouldn’t Be There

Monday, June 12th, 2017

air-conditioning-unitHere’s a question we often hear from customers. In fact it’s a question any quality HVAC company will hear multiple times:

Hey, there’s ice on my air conditioner’s evaporator coil. Is that … supposed to happen?

It’s a good question. That people think to ask it in the first place is good sign. It shows they have an understanding that, even though air conditioners blow out chilled air when they’re running, ice is probably not a part of the cooling process. Or at least, it shouldn’t be.

This instinct is correct: when ice starts to appear on the indoor coil of a central air conditioner (i.e. along the evaporator coil), it means something is wrong. In most cases, you’ll need to call for air conditioning repair in Raleigh, NC or elsewhere in order to fix the problem—and sooner, rather than later.

Humidity and Your Air Conditioner in Summer

Monday, May 15th, 2017

ac-condensersHumidity and heat during the summer can combine to make what might otherwise be a pleasantly warm North Carolina day into it a tough slog for almost anybody. The reason for this is that the increased moisture in the air is something like putting on an extra layer of clothing: it traps more heat inside the body, making temperatures feel warmer. So an 80°F day will feel like it’s actually 90°F. When relative humidity rises above 60%—a common event around here—the discomfort kicks in.
