Common AC Myths for You to Forget This Spring

Monday, March 19th, 2018

white question mark on a blue backgroundIf you’re anything like the average homeowner, you probably don’t understand the technical details of how your air conditioner works. That’s okay, we don’t expect you to—especially considering the complexity of modern AC systems and the years of training and education required to even become a licensed HVAC technician!

Unfortunately, though, there are some things you should know about your air conditioning in Denver, CO that many people do not. Due to this, you might be using your air conditioner inefficiently and even could be doing more harm than good to the system.

Does My Air Conditioner Need More Refrigerant?

Monday, July 13th, 2015

This is a question our technicians get asked time and time again. Refrigerant is a chemical blend that many people know under the trademarked name Freon. Of course, a technician would have to look at the air conditioning system closely and carefully in order to determine the problem with certainty. But it turns out that simply adding refrigerant probably won’t solve most air conditioning issues.

It’s Time to Schedule Air Conditioning Maintenance

Monday, April 27th, 2015

The days are warming up, but it’s tough to remember to think about your air conditioning system when it’s still sweater weather. Is your AC prepared? Your air conditioner develops some wear and tear each year, and dirt and debris can build up after a winter without use. By the time you turn your unit on this season, it may not run as smoothly as it did at the beginning of last summer, which could lead to high energy bills and potential repairs later on.

Your Air Conditioner Can Fight Against the Humidity

Friday, September 5th, 2014

We don’t have a lot of humid days in our part of the country, but there is always a level of humidity to deal with wherever you live, particularly during the summer months. One of the many great benefits of having an air conditioner in Denver is that it removes both heat and humidity. Cooling the air without removing the moisture in it can create an atmosphere just as uncomfortable as warm, humid air. APC Plumbing & Heating has been helping customers with their air conditioning since 1984, and we’ll explain below how your AC helps fight humidity.

Evaporator Coils

There are two sets of coils in your air conditioner: the condenser coils and the evaporator coils. The condenser coils release the heat from your indoors to the outdoor air while the evaporator coils absorb the heat from your indoor air. As the evaporator coils absorb the heat, the air above the coils chills, and your indoor blower blows this cool air into your home. But a second process occurs with the evaporator coils at the same time: when the warm air from your indoors comes into contact with the cooled evaporator coils, water from this warm air condenses. This moisture drains to the condensate tray, and then leaves your home via the condensate pipe.

Proper AC Sizing Is Important

One of the ways in which the dehumidifying process can be interrupted is with the installation of an air conditioner that is too big for your home. Removing the heat and humidity from your home is a process that is controlled by temperature. With an oversized AC, your home cools too quickly and proper dehumidification can’t take place. This can leave your indoors feeling cool and clammy.

There is no point to installing an air conditioner that doesn’t also properly dehumidify your home. One of the best ways to ensure that you have an AC that is correctly sized is to work with experts from the beginning of your purchase to the end of installation. APC Plumbing & Heating NATE-certified technicians can help you with the sizing, choosing and installation of a new AC in Denver. Call us today and let us help you fight the heat and humidity.

What is a Swamp Cooler?

Friday, August 8th, 2014

We enjoy pretty low humidity in Denver, and having low humidity gives us the option of cooling our home with a system known as a “swamp cooler”. The simplicity of swamp cooling dates back to the days of the Egyptians. Today’s swamp coolers are more sophisticated than the cooling Cleopatra enjoyed, and  with their specific advantages, may be a possible option for your air conditioning in Denver. If you are considering the installation of a swamp cooler, it’s always best to use trained technicians, like the ones at APC Plumbing & Heating.

How Does a Swamp Cooler Work?

Swamp coolers take advantage of a simple law of physics: when you add water vapor into warm, dry air, it lowers the temperature of the air. This is because it takes energy to evaporate the water, and the energy used is the heat energy in the air. Using this energy dissipates the heat, and lowers the temperature.

The actual mechanics of a swamp cooler are pretty simple. A pump circulates water from the cooler’s reservoir onto a cooling pad that becomes saturated. A fan draws air from the outside through the wet pad; as the air is pulled through the pad, it cools and is blown into your home.

Advantages of a Swamp Cooler

Swamp coolers have a few advantages other cooling products may not:

  • Very energy efficient – swamp coolers use approximately 75% less electricity than a central air conditioning system. This can lead to big savings in monthly energy bills.
  • Adds humidity to the air –low humidity can be a problem, so having an appliance that adds moisture to the air may be a good thing for your home.
  • Very “green” – swamp coolers do no use any kind of refrigerant to cool, making them very green when it comes to the environment.
  • Consistent fresh air – swamp coolers cool the air from the outside, so using one ensures that a constant stream of fresh air is part of your indoors.

Is a Swamp Cooler A Good Choice?

The best way to determine if a swamp cooler is a good fit for your air conditioning is to consult with an expert. Since 1984, APC Plumbing & Heating has helped Denver customers with their air conditioning, and we can help you, too.

Why Scraping The Ice Off Your Air Conditioner Won’t Fix The Problem

Thursday, July 10th, 2014

It is a strange sight: we have summertime temperatures, maybe even over 90 degrees, and there’s ice on your air conditioner. It may seem like this is just a surface problem, so you scrape it off, and several hours later, the ice is back.

Icing is not a normal operational condition for your air conditioner, and is actually a symptom of a bigger problem, which is why removing the ice won’t fix anything when it comes to your air conditioner. There are a few reasons that icing can occur, so if you are seeing ice build-up on your AC, call APC Plumbing & Heating today.

Reasons for Icing on Your Air Conditioner

There are 3 common reasons for ice developing on your air conditioner:

  • Outdoor temperatures are too low – your air conditioning system does not operate well below 60 degrees. While this may not be a problem during the day, the nighttime temperatures in your area may dip below 60, causing icing to occur overnight. If you need to run your air conditioner during the day to cool your property, try to shut the air off at night to avoid icing.
  • Decreased air flow – when the air flow in your air conditioning system decreases, it directly affects the heat release and cooling process, particularly where the coils are concerned. Without the proper air flow, the parts that need to be cooled don’t get cooled, and the parts that need to get warmer don’t get warmer. The disparate temperatures cause the development of condensation that quickly freezes on the cold parts of the system in the form of ice. Decreased air flow can be caused by several things, including fan issues, bent fins, dirty air filters and blockages in the system, all issues that are best handled by a trained professional.
  • Refrigerant issues – the refrigerant in your system helps with the heat release and cooling process in your air conditioning system. The refrigerant stays at a steady level for the life of your air conditioner, but it can run low if your air conditioner develops a leak. Low refrigerant in your air conditioner creates an imbalance in the heat release/cooling process that can lead to the development of ice.

Don’t Keep Scraping – Call a Professional AC Technician

Removing the ice from your system only provides temporary relief – once your system cycles a few times, it will begin to develop ice all over again if the underlying problem isn’t addressed. There is a simple solution when it comes to cool outdoor temperatures, but decreased air flow and refrigerant issues with air conditioners are best left to professionals. If you are seeing ice develop on your air conditioner, call APC Plumbing & Heating today and schedule service for your air conditioner in Denver with one of our technicians.

How Does Air Conditioning Work?

Friday, April 25th, 2014

Air conditioning has become a staple of the modern home during the summer months, when high temperatures begin to make things a bit uncomfortable indoors. But for all of our use of cooling systems, most homeowners would be hard-pressed to describe what actually goes on during the so-called refrigerant cycle. It’s the same process that refrigeration equipment uses to keep your perishable goods fresh. With the exception of swamp coolers, all air conditioning systems use a very similar process, which we outline below. Knowing more about how your air conditioner works can be useful when recognizing the signs that something is wrong.

The basic split setup for air conditioning comprises an indoor unit, which houses the evaporator coil and air handler, and the outdoor unit, which houses the compressor and the condenser coil. They are connected by piping that transfers refrigerant throughout the various components. Since we have to begin somewhere within the refrigerant cycle, we’ll start at the compressor. When you call for cooling, your compressor pressurizes a low-temperature, low-pressure gas refrigerant into a high-temperature, high-pressure gas. It is now ready to phase-change into a liquid by means of the condenser coil and the outdoor exhaust fan.

But it is still not quite cold enough to be useful as a cooling medium. After the condenser, it travels through an expansion valve that meters the flow of the liquid refrigerant, thus dropping its pressure and cooling it substantially. By the time the refrigerant has reached your indoor evaporator coil, it is ready to interact with your warm indoor air, which causes the refrigerant to evaporate as it passes through. Then the cycle repeats itself. That is the basic process by which air conditioners cool your indoor air, though there are significant variations thereof, and swamp cooling is a whole other beast entirely.

Know that you know a little about how air conditioning works, make sure to keep an eye out for any signs that you might need AC service. If you notice any frost build-up on the coils or any strange noises coming from your cooling system, give us a call. APC Plumbing & Heating offers professional air conditioning services throughout the Denver, CO area.
