Common Air Conditioner Problems

Sunday, February 12th, 2012

Air conditioners are an important part of our lives here in Dallas County. They keep us comfortable despite overbearing heat and humidity outside all summer, but because they run constantly for months and because they are such complicated pieces of machinery, they are prone to a number of problems. Here are some of the most common problems you’re likely to run into with an air conditioner and how to solve them:

Leaks

A common problem that many people ignore or are unaware of is refrigerant leakage. It is possible that when the system was installed, it wasn’t properly charged, but most of the time if your system is low on refrigerant, it is because of a leak. You can’t just pour more refrigerant in and call it good, though.

The leak needs to be fixed, both for health and environmental reasons. If you notice that your system is low on refrigerant or you smell something off – often like acetone, call a professional immediately for inspection and repair.

Sensors

An air conditioner doesn’t do you any good if the sensors don’t work properly. Improperly working sensors will fail to properly read the temperature in the home or from your thermostat. So, it might be 80+ degrees in your home but if the thermostat reads it as 72, the system won’t turn on. The air conditioner itself probably still works fine, but unless it can successfully read the temperature, you won’t get the cooling you need to stay comfortable.

Check first to see if the sensor was moved or knocked toward the evaporator coil (which will keep the temperature reading low).

Drainage problems

Your air conditioner acts as a dehumidifier as well, producing a liquid known as condensate. This liquid usually drains from the air conditioner into a designated area away from your home. However, if the condensate drain gets clogged or if the system wasn’t properly installed, that condensate can start to build up in your home. If you notice leakage around the coils, you may need a pump to remove the condensate properly.

Properly maintaining your air conditioner can usually be done with regular maintenance each year, but if one of these problems pops up, call a professional and get them fixed right away.

How to Handle Your Finicky DeSoto Heat Pump

Thursday, January 5th, 2012

A heat pump is designed to keep your DeSoto home comfortable. Warm weather, cold weather – it doesn’t matter. It should turn on when you need it and turn off when you don’t. So, when the device starts turning on and off without reason or when you need it to stay on, what exactly is the problem and how can you fix that problem without losing the heating or cooling capacity of your device.

Common Causes of the Problem

There are a number of reasons why your heat pump would turn off shortly after turning on, and most of the time this occurs in heating mode. If it occurs in cooling mode, you should have the device inspected immediately because there is likely something wrong with a core component like the compressor. For heating mode issues, here are some common problems:

  • Dirty Coils – If the coils are dirty, the device won’t be able to properly operate, especially if it has been some time since the last cleaning. Both sets of coils need to be cleaned at least once a year to avoid this becoming a problem.
  • Low Refrigerant Charge – If the refrigerant gets low, you’ll need to have it recharged because the pressure in the device will drop and it will therefore turn off after a few minutes of use.
  • Defrost Timer – If the defrost timer is forcing the device into a defrost cycle too often (usually it is set to 30, 60, or 90 minutes), the fan might turn off every few minutes after turning on. This is a common problem and is usually due to a thermostat or switch issue which can be fixed relatively easily.

Another thing to ask yourself when this problem occurs is whether the device is heating properly when on. Defrost timer issues don’t usually impinge on the heating ability of the device, while low refrigerant can. You want to make sure the device is working properly when on and not just cycling on and off without heating capacity.

Based on what you find, you’ll need a DeSoto HVAC technician to take a closer look and ensure everything is working properly. Most repairs for this type of problem are relatively simple.

What to Do if Your DeSoto Heat Pump is Blowing Cold Air in Heat Mode

Thursday, December 15th, 2011

One of the most impressive things about a heat pump is that it can both cool and heat your DeSoto home. But, if something goes wrong and your heat pump is suddenly trying to cool your home in the middle of the winter, you have a problem. Here are some possible causes of the issue and what you can do about them.

Defective Reversing Valve

The reversing valve is responsible for changing the flow of refrigerant between seasons so your heat pump can both heat and cool your home. So, if it breaks, you can imagine what happens next – you won’t switch into heating mode and your heat pump will try to air condition your home.

Defective reversing valves are hard to diagnose because the symptoms are largely the same as those of a defective compressor or condenser valve. However, because of how they are installed and where they are located, you will need a HVAC professional to inspect this problem no matter what.

Low on Refrigerant

Your heat pump should never run low on refrigerant because it shouldn’t leak, but if it does and the refrigerant gets low or if your device is simply very old, this may be a problem. Low refrigerant means that the device cannot transfer enough heat between the outdoor air and the inside air and the air that gets blown through your ducts by the air handler isn’t heated as much as is necessary to warm your house.

The problem is relatively easy to fix, though you should also have your repairman check for leaks and a possible cause of the refrigerant being low in the first place.

Not Running at All

The final problem is one you should be able to notice quite easily. If the heat pump isn’t working at all but the air handler and blower are working fine, then the device will simply blow cold air from outside or possibly even just recycled cold air from inside. In either case, the heat pump isn’t running to heat the air and therefore, you’re getting whatever temperature it is outside.

This can be caused by a number of problems so it’s important to call for a professional to inspect it immediately.

The Hardest HVAC Maintenance: Some Pointers from Arlington

Thursday, November 3rd, 2011

Do you hate to work on your own mechanical equipment in your Arlington home, like furnaces and plumbing fixtures? You aren’t alone. Many people are not cut out to be do-it-yourselfers (DIYers). They prefer to hand off their maintenance and repair chores to qualified professional. That’s not a bad thing. But there are lots of DIYers who prefer to work on their own home repairs – and those are the people who aren’t afraid to take on the most challenging jobs.

If you are looking for good ideas on how to maintain your home’s heating and cooling (HVAC) system beyond the normal filter changeouts, here are some good things to check – things that will help with the overall performance of your HVAC system.

  1. Check the ventilation system. The ventilation carries conditioned air from a main source throughout your home.  It takes a little time and effort to check your ventilation system for things like cracks or leaks around joints, but it is an important maintenance task. You may even find separations between joints or holes caused by nails. A leaky ventilation system could be sending conditioned air into attics, walls, or crawlspaces and making your furnace work extra hard just to keep your living areas warm and comfortable. Take time to visually inspect as much of your ventilation system as possible – usually metal or flex duct – and repair using joint glue, metal filler, or duct tape.
  2. Inspect the insulation. Your heating system works in conjunction with the insulation in your home to provide comfort and warmth while saving you on high utility bills. A home that is poorly insulated or not insulated at all will cause a furnace to work harder and not only send utility bills higher, but increase the possibility of mechanical failure. Replacing or adding insulation in walls and crawlspaces is a relatively easy, yet time-consuming task. You can roll down or tack up fiber insulation or blow in insulation into walls. You can also seal up cracks on your home’s walls, roof, or foundation with a number of different products. Once again, your goal is to make your heating system work less and save you money.
  3. Check the visible components of the furnace. A build-up of dust and dirt can make the moving components of your furnace work even harder, such as the motors, fan belts, contactors, etc. If you live in an area where there is lots of dust and humidity or if your home has several occupants and/or animals, it is particularly important to check your system on a regular basis. This can be done by removing the access panels and taking a vacuum cleaner hose into as many areas as possible. A good, thorough vacuuming should produce immediate results and make your furnace run much more efficiently.

Try these three steps and you may not have to repeat them for another year or so – possibly not ever again while you live in your home.

The Ins and Outs of Ductless Splits Air Conditioning: A Guide From Allen

Thursday, October 6th, 2011

So, it’s time to install a new air conditioner in your Allen house and you’re pretty sure there just isn’t enough room in the walls or ceilings to place the necessary ductwork. No problem. There is a rapidly evolving technology that allows you to have air conditioning without ductwork. It’s called mini-split ductless air conditioning and it relies on individual units placed in key locations around your house. Here’s how they work.

Multi-Zone Cooling

The first step is to install a central unit. This is your compressor and condenser and is usually placed outside like the core of a central AC system. These units range between 15,000 and 40,000 BTUs depending on how much cooling your home needs and will support up to 4 zones within your house.

Once the central unit is installed, smaller room-sized units are placed throughout your house. These units are designed for between 9,000 and 18,000 BTU spaces and are usually placed high on the wall of your room to distribute cooled air. The smaller units are connected to the main unit by refrigerant lines that are run up the side of your house (or inside if you want them out of the elements).

Because each indoor unit is individual and has its own thermostat, you save electricity by having direct control over each part of your home. In fact, the average ductless split system uses something like 30% less electricity than a standard air conditioning system.

Is it Right for You?

This is the most common question we hear and to be honest, it really depends on your needs. If you have a large house – we’re talking 3,000 square feet or bigger, a multi-zone ductless system may not provide enough cooling on its own. Most systems only support up to 4 individual units and therefore cannot cool massive spaces. However, if you have a smaller home, or more importantly have no space for ductwork, these systems are much more efficient than installing multiple window units.

AC As a Safety Feature in the Home: A Guide From Euless

Sunday, September 4th, 2011

Ask a hundred people in Euless what the primary role of air conditioning is and I’ll bet you they say “comfort”. We seek out AC to stay cool and beat the summer heat, but did you know your air conditioning is a lot more than just a convenience – it is a safety feature in the midst of heavy heat waves.

Heat Is More than Just Uncomfortable

We tend to think of heat as this massive, uncomfortable inconvenience. In reality, it is quite dangerous. According to the Center for Disease Control, heat waves killed 8,015 people between 1979-2003, more than hurricanes, tornadoes, lightning, earthquakes and floods combined in that time period.

Why is heat illness so dangerous? It comes on quickly and it’s easy to ignore the warning signs, especially when you are already uncomfortable. While hydration is important, the real risk occurs after you’ve become dehydrated – when your body can no longer keep itself cool. This is known as heat stroke and can lead to a number of life threatening conditions, especially for the elderly, infants and those with chronic conditions.

That’s where air conditioning comes in. On the CDC’s extreme heat preparedness webpage, air conditioning is listed as the number one preventative factor against heat related illness. Simply put – if you have an air conditioner, there is a much smaller chance you will get sick from the heat. Dehydration happens less frequently when you’re in an air conditioned environment, meaning that your body can regulate temperature internally and you feel comfortable – not a bad deal for a simple installation.

Staying Cool Is a Medical Necessity

Heat is more than just a direct threat. It addles the mind and makes your reaction times slower. In effect, by allowing your body to overheat, you put yourself at risk. Simple tasks like climbing a ladder or taking out the trash could result in an injury because you don’t have the energy or the mental clarity to perform them as you would on a normal day.

So, air conditioning is about a lot more than just staying comfortable – it’s a health issue. Especially if you have small children or elderly adults in the house or if anyone in your family has a medical condition like obesity, heart disease, mental illness, poor circulation, an air conditioning system is an absolute must during heat waves.

Window Units vs. Ductless Splits for Air Conditioning: Some Info From DeSoto

Sunday, August 28th, 2011

If you cannot afford or do not have duct work to support a central air conditioning system in DeSoto, there are two options – window units or ductless units. But, which is better? It depends largely on your budget, whether you rent or own and if there are any risks inherent in either choice.

Window Units

First let’s look at window units. Window units are the least expensive form of air conditioning on the market and don’t require any work on your home to install. They are good for single rooms and smaller apartments as well, and they can usually be installed by one or two people without professional assistance.

The downside of a window unit is that it cannot cool your entire home, even in an apartment. Also, window units tend to block an entire window and they pose a security risk, especially on the first floor. They are easy to remove from the outside and therefore should only be used in extreme circumstances if the window is easy to access.

Ductless Systems

Ductless systems offer benefits that counter all of the downsides of a window unit. Specifically, they don’t block the windows and are mounted inside on the walls. They are also more efficient than window units, using 30% less energy on average than a comparable window unit. They can be sized to cool your entire home and they still don’t use ductwork so extreme installation methods are not needed.

The major drawback is cost. A ductless system costs much more than a window unit, usually by 5-10 fold. They are more efficient, quieter, and less obtrusive, but they require a professional installation and the units themselves are pricy. Another issue to consider is whether you rent or own your home. Renters may not be permitted to have a system installed like this as it takes up more space and requires some work that could alter the building.

Which Is Better?

So, which should you choose? It depends on the specific needs of your home. If you have two or more zones to cool and can afford to have a ductless system installed, it is a great long term solution. However, if you are a renter, only have one or two rooms to cool or you live on a higher floor of a shared building, a window unit may be sufficient for your needs.

Your HVAC System and the Gas Line: Some Pointers From Wylie

Sunday, August 14th, 2011

What happens if you lose your gas line? What relationship does that simple copper pipe have to the comfort control of your Wylie home? It depends largely on the scope of your HVAC system and what time of the year you lose gas, but the answer is almost always that it will have a pretty big impact.

What Uses Gas in Your Home?

There are a number of components that use gas in your home. The first and most common is your furnace, but you will find that your water heater may also use a gas line and some packaged air conditioning systems use gas for heating components.

  • Heating – If you have a gas line, it’s very likely that your heating system uses gas as an energy source. It’s the least expensive of the three major energy sources (oil, gas and electricity) and gas furnaces and boilers are extremely efficient. In terms of how much gas you will use, one cubic foot of gas contains 1040 BTUs of heating energy per hour.

    So, if your furnace offers 100,000 BTUs of heating capacity, it would use 96.15 cubic feet of natural gas when running at full capacity. Keep in mind, though, that a gas furnace is rated with an AFUE rating. This is the percentage of the fuel consumed that is actually converted to heat. So, if your AFUE rating is 90%, your actual BTU production would be 90,000 for the same 96.15 cubic feet of gas. The cost of natural gas varies by location, but is generally around $1 per cubic foot.

    Boilers are very similar in their gas consumption rates. Boilers are rated for maximum output – so if you have a 15kW boiler – meaning it will burn the equivalent of 15 kWh of gas per hour when running at full capacity. Keep in mind that this is the maximum output. If you only have one radiator open, the actual rate may be much lower.

  • Water Heating – For a water heater, gas rates are charged by kWh, just like your boiler. The total is usually significantly less than for a boiler, but the same mechanics apply. Your water heater should have a placard or sheet that lists its maximum production per hour so you can determine how much gas it uses per hour when your hot water is in high demand.

Gas is a highly volatile substance and while there are a number of safety measures implemented in your home to protect your family, it’s important to ensure the gas lines are well maintained. Annual maintenance is a must to keep the gas working properly. If you do notice a leak or sudden loss of gas, don’t call a contractor – call the gas company immediately as it could be an emergency.

What Types of Air Conditioning Systems Are There?

Wednesday, July 27th, 2011

Picking out the right air conditioning system for you can actually involve a lot of steps. There are many factors to consider and you will need to understand how each type of air conditioning system functions to know what will be best in your house. Of course, before you can compare them, you need to know what the different types of air conditioning systems actually are.

Packaged air conditioning systems are probably the type that the majority of people are most familiar with. They consist of an outdoor compressor unit that is connected to an indoor air handler or furnace through ductwork within the house. The air is cooled by the compressor and then blown into the house where it is circulated through the ductwork by the air handler.

Packaged air conditioning systems are appropriate for most residential buildings and they come in a variety of sizes so that it is easy to match one to the size and dimensions of your home. However, these types of air conditioning systems do require ductwork, so if you do not already have it installed in your house, putting it in can add considerably to the overall installation costs.

If you do not want to have ducts put in or if you are only trying to cool a small space within your home, you may want to opt for a ductless mini-split system. These types of air conditioning systems are becoming more and more popular because of their excellent energy efficiency and flexibility when it comes to installation options.

Ductless mini-splits also require an outdoor compressor unit, but this is connected to one or more indoor units through refrigerant lines rather than actual air ducts. These refrigerant lines are much easier and less costly to put in place than ducts are, so mini-split systems can be installed for much less than a packaged air conditioning system in a home that does not already have ducts.

These ductless mini-split systems can include only one or many indoor units. Each of these units is controlled independently of the others, making it possible to maintain different temperatures in different parts of your home.

For larger buildings and commercial spaces, central air conditioning systems are generally the preferred option. They are set up essentially the same way as packaged air conditioning systems but on a much larger scale. However, just like packaged air conditioning systems, central air conditioners rely on ducts to get the cooled air to the various areas of the building.

Can I Choose Environmentally Friendly Coolants?

Monday, July 25th, 2011

Air conditioners are indispensable in many parts of the country, but their environmental impact has long been a source of controversy. In particular, the coolants that were used in the earliest air conditioners, chlorofluorocarbons (CFCs) have done quite a bit of damage to the Earth’s protective ozone layer.

When this affect was discovered, countries all over the world acted to have them phased out of production and use in air conditioning. While CFCs have not been produced since 1995, there are still many air conditioning units functioning today that use CFCs. As these units wear out, of course, the CFCs will gradually disappear from use altogether.

Another type of coolant that is commonly used in air conditioners is hydrochlorofluorocarbons (HCFCs). These have a slightly lower environmental impact than their cousin CFCs, but they are still not ideal in terms of preserving the ozone layer and impeding the progress of global warming. HCFCs are gradually being phased out as well, and they will no longer be produced at all by 2030.

However, it is still possible to buy air conditioners that use HCFCs as a coolant, and if you can avoid this, you should. HCFCs are not nearly as environmentally friendly as some of the other options on the market, and if you are concerned about the effect that these types of chemicals can have on our environment, it is best to steer clear of air conditioners that use HCFCs.

So what coolants are considered environmentally friendly? Well, there are actually two options in this regard. The first are hydroflourocarbons (HFCs). Although they are quite similar to CFCs and HCFCs, HFCs do not contain chlorine and so do not do the type of damage that their predecessors were capable of. You can find air conditioners that use HFCs relatively easily by looking for an “ozone friendly” label on the box.

Refrigerant blends are also becoming a more and more popular environmentally friendly coolant solution for air conditioners as well. Although these types of coolants typically cost more to produce and so can drive up the cost of the air conditioners that use them, they should begin to come down in price as they are more widely adopted across the industry. Just as with HFCs, look for the “ozone friendly” label to identify air conditioners that use refrigerant blends as coolants.
