Does a Fried Compressor Mean the AC Must Be Replaced?

Monday, September 2nd, 2019

compressor-in-ac-unitNow here’s an unpleasant problem you may run into during the last days of summer: an air conditioning system that doesn’t work because the compressor has died. The compressor is the literal heart of a cooling system, since it’s the component that causes refrigerant to circulate through the system, turning a cool low-pressure liquid into a hot high-pressure gas. When a compressor is fried because of a burnt-out motor, an air conditioner turns into nothing more than a large fan.

You may have heard that a dead compressor means the end of the line for the air conditioning systems It’s so expensive to replace the compressor that the more cost-effective choice is to have a brand-new cooling system put in. But is this true? If air conditioning repair in Burlington, VT won’t save the compressor, is the next step working with us to get a new system?

When Does a Ductless HVAC System Make Sense for a Home?

Monday, August 19th, 2019

ductless-mini-split-on-the-wallDuctwork is what originally allowed air conditioning and heating systems to spread conditioned air throughout a house, rather than concentrating it in one place. The earliest ducted systems were nothing more than metal pipes extending from basement furnaces (or even just fireplaces) that allowed heat to rise to different rooms in a building. Today, forced-air central AC and heating systems use powerful air handlers and efficient ducts to see that comfort is sent throughout a house.

But technology has also developed ductless HVAC systems. Also called ductless mini split heat pumps, these HVAC systems operate like standard heat pumps (cooling and heating air through circulation of refrigerant), but the single outdoor unit connects through walls to separate air handlers placed around the house. Each air handler has its own fan and refrigerant coil so it can blow the cooled or heated air directly into the living space—no ductwork required.

A Short-Cycling AC Is Bad News: Here’s Why

Sunday, August 19th, 2018

spinning-fan-closeup“Short-cycling? What’s that?” We know it sounds like a strange circus act or a short-distance bicycling competition. But it’s a term for faulty behavior from a cooling system. If you hear your home’s AC starting and stopping multiple times over an hour, that’s short-cycling. This isn’t something you want to happen, since it spells trouble for your air conditioning in Burlington, VT. In most cases, you’ll need to call up HVAC technicians to find out why the AC is short-cycling and what to do about it.

Why is short-cycling a problem?

First, we must explain in greater detail what short-cycling means. When the thermostat of a house makes a request for cooling, the air conditioner starts up its fans and the compressor motor. The compressor is the component that allows for heat exchange and cooling of the air. The compressor remains running until the thermostat registers it has reached the target temperature, and then the compressor cycles down. In mild weather, the AC cycle lasts approximately 10 to 15 minutes and completes 2 to 3 times per hour.

Repairs You Can Do Yourself on Your AC

Monday, July 23rd, 2018

wrenchesWhen an air conditioner loses its cooling power on a hot summer day, or even loses all of its power, it can be a serious emergency. You don’t want to be stuck for long in your home without cooling when the outdoor heat is rising. What can you do?

Trying to fix the AC on your own might be the first idea that pops into your head. And why shouldn’t it? If you want something done right, do it yourself!

Except this isn’t always the case. There are plenty of repair jobs you wouldn’t try on your own unless you were a trained professional, and fixing an air conditioner is one of them. It takes a trained HVAC technician to do them. Only they have the knowledge and tools to accurately diagnose and fix a serious air conditioner malfunction.

The Advantages of a Zone Control System

Tuesday, July 25th, 2017

room-ventCentral heating and air conditioning is one of the greatest inventions in the modern home (maybe not at the level of indoor plumbing, but we’re not here to debate old sayings). One comfort system can distribute cooled and heated air to rooms throughout a house.

But there’s a flaw in the standard way a central HVAC system is designed, which is that it’s an “all-or-nothing” proposition. On a hot day, when the air conditioner turns on, cooled air goes to every room. That sounds great at first—until you realize that some of these rooms aren’t occupied. This is an expenditure of energy the home doesn’t need.

And, thanks to the creation of zone control systems, it’s an unnecessary expenditure of energy. Zone control allows for better manipulation of how cooled and heated air is distributed around a house.

Taking the AC for a Test Run to Prepare for Warm Weather

Monday, April 3rd, 2017

fan-on-white-backgroundNow that spring has arrived—officially, if not as far as the weather is concerned—you’re probably making various “spring cleaning” plans and prepping your home for the middle of the year and the change in seasons. One of the important tasks to take care of is to arrange for a routine maintenance inspection and tune-up for the air conditioner, something we talked about in our previous blog post.

Regular maintenance gives an AC the best chance to make it through the coming summer without problems. But maintenance isn’t magic, and it’s a good idea to give your air conditioner a “test run” yourself a few weeks afterwards and before the real heat arrives. There are a number of common air conditioning problems that can strike even a system with the best regular maintenance, so it’s wise to be as prepared as possible. Testing the air conditioner allows you to catch any lingering trouble and have it fixed in time for summer weather.
