Add Insulation to Cut Down on Cooling Bills

Monday, April 18th, 2016

Lakeway, TX residents don’t think about home insulation. Our winters are fairly mild as winters go, and while we get our share of chilly nights, that doesn’t necessarily require the level of insulation you’d need in, say, Maine. But what most people don’t understand is that insulation could be just as important in the summer as it is in the winter. And as mild as our winters are, summers can be absolutely unbearable. Additional insulation in your home can cut down on your cooling bills and help your air conditioner function more effectively. Here’s how.

Qualities to Look for in a Commercial HVAC Service

Monday, March 14th, 2016

Lakeway, TX and other communities in the Austin area feature their share of businesses. If you’re a business owner or an office manager in the area, you know how vital a good commercial HVAC system is to your company. It means reliable heat in the winter and cool air in the summer: keeping your employees comfortable, protecting important equipment like computers, and providing an inviting environment for customers to visit and revisit. Chances are, you don’t have an HVAC expert on staff, which means you’ll need to hire a service not only to install and replace a commercial HVAC system, but to provide timely repairs and maintenance. Those needs differ from residential HVAC systems, so before you task a given company to keep your commercial system running, there are certain specific qualities you should look for.

What is Short-Cycling?

Friday, February 20th, 2015

Short-cycling is one of the most damaging behaviors that a furnace can experience, causing all sorts of problems in other parts of the system and increasing the chance of a complete breakdown. It is characterized by the system rapidly turning itself on and off over and over again for a long period of time. Let’s take a look at what the causes of short-cycling are, and how you can prevent it from happening.

The Process of Short-Cycling

Short-cycling is caused by the furnace overheating, which activates a safety device called the “limit switch.” The limit switch shuts down the entire system to prevent it from damaging itself by overheating, but it doesn’t actually address the cause of the overheating. The limit switch is simply a stopgap measure, designed to preserve the health of the furnace as much as possible until the source of the overheating can be fixed. Once the furnace has cooled down sufficiently, it will reactivate in response to the thermostat. It will then overheat again, provoking the limit switch and starting the whole cycle over again. If the source of the overheating isn’t found and fixed right away, this prolonged cycle of turning on and off can cause extreme damage to parts of the furnace. The heat exchanger can develop cracks from the strain, causing a fire risk and releasing combustion gases into the ducts.

What Causes Short-Cycling?

The most common cause of short-cycling is actually one of the easiest furnace problems to fix. All furnaces include an air filter in their air return ducts, designed to protect the system from dust and debris that might otherwise damage it. If not cleaned or replaced every couple of months, however, the air filter will become so clogged with dust that it will prevent the flow of air into the furnace. This causes the internal temperature of the furnace to steadily rise, kicking off the whole short-cycling problem. The easiest way to prevent short-cycling, therefore, is to have your furnace air filter changed at least once every other month.
