Air Conditioning Maintenance | Heating and Air Conditioning

While the air filter may seem to be a fairly innocuous component of the heating and air conditioning system, its function is essential to keeping dirt off of the coil and out of the system. Dirt and dust can coat the evaporator coil, preventing the system from efficiently, or properly cooling your home. Furthermore, when dust finds its way into the moving parts of the system, it creates friction and contributes to wear and tear on the moving parts. This results in premature and unnecessary failure of your home's heating and air conditioning system. Changing the air filter is the first step in air conditioning maintenance.

Simply stated, the filter is the first line of defense for your heating and air conditioning system. In addition, the air filter assists in cleaning the air in your home by scrubbing dust, dirt, and pollen from the air. The dirty filter you change each month provides the proof of this.

Beyond dirt entering the system, a dirty air filter also poses the problem of increased resistance and reduced airflow. This in turn causes the heating and air conditioning system to perform poorly, increasing energy usage, and risking damage to a system struggling for air. Not only that, but if the filter is too dirty, it starts to become a source of poor air quality in the home itself.

Homeowner's occasionally will remove an excessively dirty filter without inserting a new one. While this resolves the low air flow problem, it allows the dust and dirt to build up on your evaporator coil and eventually cause it to fail.

System Maintenance

Routine maintenance such as changing filters, and keeping air returns, outdoor condensers and heat pumps clear of surrounding weeds, shrubs or other objects, can be handled by most homeowners, but other maintenance tasks require professional heating and air conditioning service.

Humidity Control

High humidity leads to more than sticky discomfort and feeling hotter than it actually is. The excess moisture leads to mold and mildew, deterioration of wooden structures and difficulty breathing for those with heart and/or respiratory issues. Modern air conditioners dehumidify as they cool the air in your home. This moisture that is removed from the air is the water that you see draining away.

However, in excessively humid climates the consequential dehumidification that occurs during the air conditioning process may not always be enough to keep the indoor humidity conditions within the recommended 30-50% level.

Excessively hot, humid climates may require a dehumidifier. Even a stand-alone dehumidifier will assist you, though only in the room where located. If you are interested in adding a whole house dehumidifier to your home's heating and air conditioning system, give us a call.

In addition, it may benefit your home comfort to have a Garland Heating and Air Conditioning professional check your heating and air conditioning system. An improperly functioning system or one that is too large can result in increased humidity in the home.

A recent study determined 50% of homes were fitted with an oversized air conditioner which cools the home quickly. Bigger isn't always better, especially when it comes to your air conditioning. Furthermore, if you have recently provided a lot of energy upgrades to your home to make it more efficient, your HVAC system may now be oversized for the home, with humidity issues resulting. A Garland professional can assist you with this problem.

Household Habits Can Contribute to Increased Humidity

Setting the thermostat fan to the "on" position blows air all the time. Through the cracks and crevices in the home's envelope, vent pipes and unsealed ducts the moisture that your air conditioner removes is returned to the home from outdoor air. Use fans or turn on the dehumidifier to increase your comfort between cycles. Better yet, seal all of those cracks and crevices where air intrudes around doors, windows, pipes and cables, and ensure the fireplace flue is closed.

Use exhaust fans during moisture-producing activities. When cooking, showering or performing other moisture producing activities in the home, use the exhaust fans to remove as much moisture as possible.

When the outdoors are hot and humid, close all windows and doors and don't ventilate outdoor air to the inside.

Variable Speed Air Conditioning Repair | Plano, TX

Air Conditioning Repair Plano

Variable Speed Motors | Air Conditioning Repair Plano, TX

Today's best air conditioners use 20% to 40% less energy to produce the same amount of cooling as air conditioners made just 10 years ago. Selecting an energy efficient air conditioner is only one part of the process of a new air conditioning installation. Proper sizing and the quality of installation are essential in determining air conditioner efficiency. An oversized unit will not adequately remove humidity, while an undersized unit will not be able to attain a comfortable temperature on the hottest days, and can result in premature wear, and the need for air conditioning repair in Plano, TX.

A variety of features are available for modern air conditioners today, and one that will greatly increase efficiency and comfort is a variable speed blower motor. The variable speed blower motor moves at the required speed as determined by sensors for precise control of conditioned air.

When you are in need of a new AC system, Garland Heating and Air Conditioning offers HVAC systems with variable speed motors for new or replacement installations. Contact us for further information, or to schedule a consultation.

The Advantages of a Variable Speed Furnace

  • Air Quality: Variable-speed motors with humidistats allow you to control the humidity levels in your home. For optimal comfort, the relative humidity should be between 30 and 50 percent. The consistent airflow of these motors also improves air filtration for cleaner air.
  • Electrical Efficiency: Variable-speed motors consume less electricity than conventional motors, using about one-eighth of the electricity when operating at half speed compared to a conventional motor. Because of the reduced speed when needed, the variable speed motor can outlast a conventional motor, reducing the need for air conditioning repair in Plano, TX.
  • Zoning: Variable speed motors and zoned systems complement each other in energy efficiency. Zoned systems enable you to control the temperature in different areas in the home independent of each other. When combined with a variable speed motor that adjusts its output to the speed required, comfort is achieved along with increased energy efficiency, and reduces wear and tear on the system and the consequent need for air conditioning repair in Plano, TX.

How Systems With Variable Speed Motors Work

A variable speed motor runs on a broad range of speeds providing precise control of conditioned airflow. When temperatures are extreme, the motor operates at a higher speed. Whereas, when temperatures are mild, the motor operates at a slower speed for an extended amount of time. Conventional fans run at one speed, consuming a consistently higher rate of electricity than a lower speed would.

Sensors automatically determine the amount of required airflow, saving energy when the variable speed motor operates at a lower speed. If you are interested in a variable speed motor, your existing system may be compatible. Our certified technicians provide HVAC installation, service, maintenance and air conditioning repair in Plano, TX.

Unlike single, two or three speed fans which operate at a set speed for each fan speed, a variable speed motor operates from 0 RPM to full speed and anywhere in between. This enables the HVAC system to operate at the precise speed your home requires based on the current conditions.

HVAC systems remove heat and moisture from the air moving through them. When the air conditioning runs, a conventional single speed fan runs at the highest speed all of the time. This results in less moisture being removed from the air. A variable speed motor removes a higher amount of moisture from the air than conventional fans, by operating at a slower speed when the air compressor first kicks in, allowing the humidity to be more efficiently extracted from the air.

As air moves over the coils it is cooled, activating the fan speed to increase, delivering cold, and dehumidified air to your home. A variable speed fan motor will increase your comfort by providing dryer air, and will reduce wear upon the system by operating at a lower speed, resulting in the reduced need for air conditioning repair in Plano, TX.

Humidity affects comfort by making the air temperature feel hotter than it actually is, and promotes the growth of mold and mildew. A variable speed fan motor prevents these issues by limiting the air flow until the moisture is removed from the air. The removed moisture drains out of the drain, rather than ending up in the duct system where mold can grow.

Spring Air Conditioning Repair Dallas

Spring Air Conditioning Service | Air Conditioning Repair Dallas

Providing the pre-season spring air conditioning service that your HVAC system requires ensures it maintains peak operation, extends its life span and reduces the frequency of the need for air conditioning repair in Dallas. In other words, annual maintenance on the air conditioning system provides preventative maintenance.

Common problems related to air conditioning failure are a dirty filter, low refrigerant, a malfunctioning fan and a thrown breaker. Most of these breakdowns are common problems that would have been detected during the annual service of an air conditioning tune-up.

A dirty filter is a simple DIY solution with the recommendation to check on the filter every 2-4 weeks and to replace the manufacturer recommends, or as necessary.

Low refrigerant is due to a leak which can be detected in your spring tune-up. It may be working for now, but once the refrigerant level drops below the threshold, you will find the ac blowing warm air. The spring tune-up can clean, oil and inspect the system, and any problems will be identified and repaired. While a properly functioning system is less likely to break down, when the system begins to age, or has been grossly neglected over time, repeated leaks indicate a problem, or even the potential need for a new air conditioning installation.

Ignoring a leak can damage the compressor which pumps the cooled air into your home. A compressor is the most costly component in your air conditioning system, and catching the leak during a tune-up will cost a fraction of the potential cost of a compressor for air conditioning repair in Dallas.

Malfunctioning fan motors are another common cause of air conditioner problems. You may hear unusual sounds, or notice the air movement from the vents isn't as much as it was. The spring tune-up can detect a weakening or faulty fan and enable repair now, preventing the need for an additional service call to provide air conditioning repair in Dallas.

Frozen coils can occur with a refrigerant leak, but a dirty air filter can also cause this. Frozen coils may or may not be visible depending upon the type of system that you have. If you experience the ac blowing warm air, first check your filter and change if it's dirty. If that doesn't correct the problem you will need to call your air conditioning technician for air conditioning repair in Dallas.

A tune-up can also reveal wiring hazards inside the ac system. This condition can cause circuit breakers to shut off and can be a fire hazard. In addition, loose electrical connections can cause a significant increase in the electric bill.

The inspection during a tune-up may reveal a clogged drain in the condensate pan, which can result in water overflowing and potential damage to your home. Improperly removed condensate will also increase the home's humidity making you feel hot and sticky.

A dirty coil is an additional issue the spring tune-up can identify. A dirty coil can result in reduced cooling and a drop in efficiency of 30-40 % as the system runs longer trying to cool the home. A dirty coil will also reduce the life span of the air conditioning system.

The spring tune-up can save you money by reducing breakdowns, extending its life span, as well as providing the optimal performance and saving you energy dollars. Have your air conditioning thoroughly inspected and serviced now before the cooling season arrives.

Garland Heating and Air Conditioning provides air conditioning repair in Dallas, as well as Plano, and the surrounding areas. Our NATE certified and experienced technicians provide the superior spring air conditioning service you need to maintain your comfort. Don't delay your tune-up; contact the experts at Garland today to schedule your spring service.
