How High Humidity can Damage Your Air Conditioner

Wednesday, April 30th, 2014

Believe it or not, high temperatures aren’t the only thing that your air conditioner must fight. High humidity plays a big part making our homes uncomfortable too, and unless your air conditioner can combat it, it’s not going to do its job. Air conditioning repair in Gainesville must often deal with overworked A/C units, whose components have worn down under the strain and need to be replaced before the unit will function again. Our stifling Florida mugginess often plays a large role in that, and understanding the reasons why can help you get a jump on correcting the problem.

How Humidity Damages Air Conditioning

We stay cool by sweating, which sends moisture to the surface of our skin and cools us off when it evaporates into the air. As long as relative humidity levels stay below about 55 percent or so, that biological process isn’t unduly affected and your body can sweat normally. When humidity levels increase beyond that, however, there’s too much moisture in the air to absorb the sweat off of your skin, and your body won’t cool down the way it should. Needless to say, our relative humidity levels are often higher than 55 percent here in Florida, especially during the hot summer months.

Ostensibly, your air conditioner can pull humidity from the air in your home and help keep it comfortable. That process, however, often forces your air conditioner to work harder in order to lower that humidity level. As a result, the various components undergo greater strain, which increases the likelihood of a breakdown somewhere along the line.

In some cases, your AC unit may be powerful enough to handle the additional workload that our muggy atmosphere provides. In other cases, however, you might want to consider upgrading your air conditioner, which can help prevent high humidity from damaging it.

Touchstone Heating and Air Inc. handles air conditioning repair in Gainesville, and can fix the issue of high humidity in your home with ease. Pick up the phone and give us a call today.

My AC is On, But Hot Air is Coming Out of My Vents

Tuesday, November 12th, 2013

It can come as quite a shock, especially on a hot day. “My AC is on, but hot air is coming out of my vents!” You don’t need to be an expert to know that something’s wrong, and when problems arise with your air conditioning, Gainesville FL weather can be particularly unforgiving. What causes an air conditioner to blow hot air? The obvious answer is that the thermostat hasn’t been set properly, or perhaps needs replacing. Beyond that, the possible causes grow more serious.

Air conditioning systems depend on refrigerant gas cycling through a closed system in order to function as they should. If the unit is blowing hot air (as opposed to not blowing any air at all), then the problem likely lies somewhere within this system. For instance, if the compressor is malfunctioning, it won’t be able to turn the refrigerant gas into a liquid – a vital step towards allowing it to cool the air.

The problem may also stem from a leak in the system, releasing refrigerant into the air. If too much refrigerant is lost, the process can’t work at all, and no cold air will be generated. You can spot this condition by the presence of frost on the evaporator coils: evidence of all the coldness that isn’t going into your home.

In some cases, the problem may be caused by a leak in your duct system or somewhere similar. Leaks can pull hot air into the ducts while the air conditioner is running, substituting the cold air with warm air.

Regardless of the causes, you need a trained expert to find a solution. The pros at Touchstone Heating & Air handle any problems you may have with your Gainesville FL home’s air conditioning system. Call us today to schedule service!

Air Conditioning Repair Question: Why Is My Fan Running but AC Not Cooling?

Tuesday, October 29th, 2013

In matters of air conditioning repair, Gainesville FL know they need to schedule cerise right away. The sooner you can spot a problem, the more rapidly you can contact a qualified service technician to help. It helps to know the signs that you need AC repair, so that you can spot them early and call in the cavalry before something worse happens. For example “why is my fan running but AC not cooling?” is a common question we experience in our work. The answer is pretty straightforward.

The fan serves to blow cool air into your home. As refrigerant moves through the evaporator, it goes from a liquid state to a gas state, absorbing heat from the surrounding air in the process. A blower then moves the air through your ducts into your home. If the fan is running, the problem obviously lies elsewhere, and if you’re getting a good flow through your vents, there isn’t any blocked in your ducts.

The problem therefore lies in the cooling cycle itself. In some cases, it may be that the refrigerant levels have dropped below acceptable levels. Ice will form on the evaporator coils: which insulates them and prevents them from absorbing heat. Another problem may arise with the compressor motor itself. If it isn’t running, the refrigerant isn’t circulating and the air isn’t getting cooled.

Regardless of the causes, a good repairman can hunt the problem down and fix it quickly. When dealing with air conditioning repair, Gainesville FL has a team of experts ready to help. Touchstone Heating & Air has served North Central Florida since 1998, and offer 24-hour service for emergencies. We pride ourselves on your complete satisfaction, and we know how important it is to get your air conditioner up and running again.

Air Conditioning Tip: When to Use the Fan Only

Tuesday, October 22nd, 2013

We experience some seriously hot and humid weather around here, and a reliable air conditioning system is often your only weapon against the soaring temperatures outside. That air conditioning system uses a lot of energy, however: as much as 16% of your total household electricity, according to the U.S. Department of Energy. You can cut that down by using your system’s “fan only” feature, which stops the cooling process but continues to circulate the air in throughout your home.

The most obvious period is right after you’ve shut your air conditioning down for the day. With the cooled air still in your house, you can turn on the fan and help circulate it, staying cool for longer. This can keep your house from becoming stuffy when the AC is not running, and also make sure your air is going through your air filtration system.

You might also consider using the fan only after the sun goes down, or when cooler breezes blow near your house on days when the humidity levels are lower. The flow will refresh the existing air while keeping your temperatures down to agreeable levels.

You can help this process by ensuring that your air conditioner is functioning as it should and that the blower fan isn’t bent or damaged. Knowing when to use the fan only won’t do you much good if the air conditioner itself is broken. For expert service and advice, contact Touchstone Heating & Air!

Air Conditioning Repair: Causes of Grinding Sounds

Monday, October 7th, 2013

If you live in Gainesville, FL, you know that air conditioning repair is not something you want to put off. We need a swift repairman to correct any problem before the next heat wave hits and we need to be able to spot signs of trouble before they lead to bigger issues. Otherwise, our cool, comfortable homes will be at the mercy of our patented muggy weather. A prudent homeowner will notice when his or her air conditioner isn’t performing as it should. To cite one obvious example, spotting the causes of grinding sounds when your air conditioning unit turns on can help get the issue resolved that much more quickly.

Obviously, grinding sounds aren’t good when they’re coming from your air conditioning. The sound usually results from metal parts rubbing up against each other, a sure sign that something is broken. The blower fan is one common cause of grinding sounds. When it’s bent or misaligned, it can scrape up against nearby parts, causing friction and resulting in serious damage. In some cases, debris such as twigs can get caught in the fan blade as well, resulting in damage to the fan itself.

Grinding noises aren’t limited to the fan, however. They can occur in motors in the system which overheat or otherwise malfunction. With some air conditioning units, these components have automatic shut-off systems that kick in whenever they malfunction. Those that don’t will continue to run, however, making that awful grinding noise and causing further damage each moment.

Whenever you hear that noise, don’t hesitate. Shut off the unit and call an air conditioning expert. A qualified professional should be able to isolate the problem and correct it with a reasonable amount of expediency. If you have any questions about Gainesville FL air conditioning repair, call Touchstone Heating & Air for help. Our staff of trained professionals will track down the causes of grinding problems, then give you an accurate assessment before conducting repairs with speed and accuracy. If your AC unit is making sounds that it shouldn’t, don’t hesitate to call us today.

Air Conditioning: Reducing Energy Costs

Monday, September 23rd, 2013

Did you look over your air conditioning bills after a muggy Florida summer and wonder what you could’ve done to lower them? Touchstone Heating & Air has some good advice on what you can do to get those AC electric bills down and keep them down. When it comes to air conditioning in Gainesville, FL, trust our experienced team to help you get the most from your system.

A very simple step you can take to use less power with your AC is to make more use of the “fan only” mode. Some people don’t realize that this mode uses significantly less power than when the unit is set to cooling. With the air conditioner set to “fan only,” no power goes to the compressor that sends refrigerant through the system. Although you won’t get cooled air from your vents, you will get excellent air circulation to provide you with relief from stagnant air.

Try to avoid the temptation to crank your AC to its coldest setting. According to the EPA, if you raise your thermostat a mere six degrees from 72° to 78°, you can save up to 18% on your electricity bill each year. Most people will find 78° comfortable no matter the weather outside. Stabilize your daytime use at this temperature, and then take advantage of the cool evening temperature to raise it further or to shut it off and you should see a positive effect on your monthly power bills.

Finally, have a professional complete preventive maintenance on your air conditioner to make sure that it operates efficiently. Dirt building up inside the case, overworked motors, poor connections, and refrigerant leaks will all lead to an AC that sucks up more energy than it should. The better your AC runs, the less power it will waste. Plan to get check-ups twice a year for your air conditioner. The fall is a good time to start, since technicians will have more open schedules.

Touchstone Heating & Air takes pride in making customer satisfaction our top priority. Your air conditioning in Gainesville, FL is in good hands when you call on us.

Air Conditioning Repair: Fan Not Turning On

Monday, September 16th, 2013

With high levels of humidity and a warm season that lasts all year, living in Florida requires a reliable air conditioner to keep you comfortable. If an important part of your AC stops working, like the fan, you can’t afford to wait to do something about it. If you need air conditioning repair in Gainesville, FL, look no further than the skilled staff at Touchstone Heating & Air for professional help.

Your air conditioner needs two fans to operate, one each in the inside and outside units. The inside fan blows cool air through your vents, and the outside one takes care of removing the heat. If either fan stops working, you will not receive the cold air you expect from your AC.

The most common cause of the fans failing to turn on is a burned out motor. Without maintenance, the motors can run down from long use and overheat, damaging their wiring. It’s a good idea to have an HVAC specialist take a look at your AC after the intense summer months so you can avoid a motor failure that will leave your fans stuck in one place.

A problem with the capacitor could be one of the reasons for your fan not turning on. The capacitor is a small cylinder-shaped device that acts as the catalyst for the motors that run the fans as well as the compressor. If the capacitor is unable to send voltage to the fan motors, they won’t operate. Don’t try to repair a burned-out compressor on your own—there is a danger of electrical shock! Let a professional handle this problem.

It’s possible that all the components inside the air handler and the condenser are working fine—and the problem is actually the thermostat. If your thermostat is improperly calibrated, it might think that your home doesn’t need the fan in operation and won’t turn on. You might need to have the thermostat fixed or perhaps have an up-to-date unit installed in its place.

A non-working fan needs attention right away. Don’t hope that it will fix itself and start spinning the next time you turn on your AC. Regardless of the root problem, Touchstone Heating & Air can get your air conditioning repair needs taken care of in Gainesville, FL. Contact us today to schedule service.

Air Conditioning Tip: Your AC and Your Generator

Monday, September 9th, 2013

Hurricane season is coming up, and power outages are something Florida residents need to seriously consider. Using an emergency generator or a standby generator is something many people rely on. But how does a generator affect your air conditioning system, and vice versa?

Touchstone Heating & Air has many years of experience with the air conditioning trouble you might expect with the troublesome hurricane weather in Gainesville, FL. Here are a few things you should know about your air conditioner and your generator:

  • Starting up your AC: Like many machines, the time where your air conditioner needs to draw the most power is when it turns on. When using an emergency or standby generator, try to avoid numerous start-ups with your AC. Think of it like flooding the engine of a car: too many tries, and the whole thing shuts down.
  • Know your power needs: How much energy does your AC require to run? How much can your generator give it? You don’t want your air conditioner overloading your generator, or your generator to fail to provide enough electricity to operate your air conditioner. An HVAC expert can help you determine the best fit between the two.
  • Prepare Your AC for the season: If your air conditioner has not received regular preventive maintenance, some of its components can cause serious problems when hooked up to a generator. An overloaded compressor, a malfunctioning capacitor, or overheated fan motors: any one of these could cause a power surge and damage your generator. You will need to call in a specialist to diagnose possible voltage issues with your air conditioner before hurricane season starts. With this kind of power involved, don’t risk trying to fix any the AC yourself!

Hurricane season can be a frightening time. But if you’ve taken care of your air conditioner, you shouldn’t have to worry about it causing trouble with your emergency or standby generator. To get ready for the season, call our Gainesville, FL air conditioning technicians. We can help you with the maintenance you need to feel secure. We also serve Lake City and the surrounding areas.

Air Conditioning Guide: 3 AC Components You May Not Know About

Thursday, August 22nd, 2013

Air conditioning units are complex pieces of machinery, requiring numerous components to function together if they’re going to work as they should. Most people are aware that refrigerant  is used, and you can hear fans and blowers run any time you turn the air conditioning system on. But other components play an important role in the process – especially in cities like Gainesville, FL, where AC units run constantly during the hot summer months – and non-experts may not be familiar with their purpose and function. Here are 3 AC components you may not know about and the roles they serve in the cooling process.

  • Condensate pan: The condensate pan collects condensation that forms on the evaporator coils, then moves it out of the system via a condensate drain. This prevents the condensate from infiltrating the rest of the system, possibly causing water damage.
  • Expansion valve: The expansion valve serves as a sort of “gateway” to the evaporator coils, where the actual cooling process takes place. Refrigerant arrives at the valve in liquid form and under a great deal of pressure. The valve acts in a manner similar to an aerosol can, releasing a set amount of the liquid into the coils. The liquid evaporates and pulls heat from the nearby air, which a fan then blows into your home.
  •  Condenser coils: The condenser coils put the refrigerant in a liquid state before it moves to the expansion valve. The refrigerant enters the coils as a gas, where it its then cooled to a liquid form. This heat dissipates off the coils, which is then blown out of the system by a fan. For this reason, condenser coils are a part of the outdoor unit.

If you experience problems with your air conditioning system, whether it stems from an unknown component or something more recognizable like the thermostat, it pays to contact a professional as soon as possible. The experts at Touchstone Heating & Air handle air conditioning issues throughout the Gainesville FL area. Call us today and make an appointment.
