Westlake Air Conditioning Tip: Variable Speed Fans and Energy Efficiency

Monday, August 27th, 2012

One of the great improvements in air conditioning and heating technology is with the variable speed fan.  Westland Heating and Air Conditioning has years of experience working with Westlake air conditioning and heating systems that utilize this wonderful technology and as such can help you understand how variable speed fans provide great energy-efficiency.

Variable speed fans are just that: fans inside air conditioners and heaters that provide multiple levels of speed for optimal comfort and energy-efficiency.  The fan is the part of the system that moves the cooled or heated air through the ducts of a building.  A variable speed fan is actually controlled by a variable speed motor that can be run on a range of speeds in order to accommodate a specific need at any given time.

Since the fan inside these systems is used quite often, the more efficient it is the more efficient your heating or cooling system will be.  Variable speed motors ultimately save money on energy bills since they consume less power to run them than standard motors.  The higher efficiency air conditioning and heating units all use variable-speed blowers and fans.

Variable speed blowers can work at different speeds.  When temperatures outside are more temperate it will run at a lower fan speed, using less energy to do so (normally half the electricity needed during harder usage times).  When the temperatures outside skyrocket or drastically drop, the fan will run at a higher speed, offering the most amount of indoor temperature change possible in a shorter amount of time.

Here is an example of how the variable speed fan runs:

  • When the thermostat turns on the variable speed blower during cooling or heating, the blower will begin by running at half-speed.  This gets the coils cooling down properly without using excess energy to do so.  At this speed the fan is using 50% less energy than a standard fan.
  • After a few minutes the variable speed fan will adjust to working at ¾ speed and hold that rate of speed for much longer.  At this speed it is still using 25% less energy than a standard single-speed blower.
  • Temperature checks are taken periodically.  It may take a few minutes of blowing the fan at top speed to get temperatures right, or it could remain at ¾ speed the full time the system is running.  Once the building is within 2 degrees of the desired temperature it will stay at the ¾ speed until the proper temperature is attained.  This process saves money in power bills to run the air conditioner or heater every time it is used.

In this scenario, if you keep your building at a standard temperature all the time, you will hardly ever have to use the fan at full speed because temperatures will remain fairly constant throughout the day.

An additional benefit of a variable speed fan is improved air quality.  When a variable speed fan is set to “on” or to constantly operate, even after the heating or cooling portion is completed, the fan will work at half speed in order to circulate the air in a building and ensure that there is even distribution of cooled and heated air, even after the proper temperature is reached.

Common Problem Areas for North Olmsted HVAC Systems

Monday, August 20th, 2012

The following are a few of the most common problem areas for North Olmsted HVAC systems.  It is important to pay attention to these and contact the professionals at Westland Heating and Air Conditioning when they do occur.

Some of the most common problem areas for HVAC systems that are already in place have to do with power lines, drains, and venting.  When one of these main systems need attention, an immediate repair is best.

The power lines on HVAC systems are what keep them running continually, day in and day out, all year round.  An HVAC system uses a lot of electricity and if it shuts off suddenly or frequently shuts down, it can be a sign of a power issue.  There could be damage to electrical lines from extreme weather conditions, animals, or other factors.

The drains on HVAC systems are important in keeping the system functioning properly.  They release condensed water that builds up inside the HVAC as it runs, and if drains clog there is no way for this water to escape.  Drainage problems can mean an overflow of water, which can in turn seriously damage your system.

The vents on your HVAC system allow air to be dispersed throughout your home. They also allow air to return and be heated or cooled once again.  When vents become clogged it can result in more than just stuffy air. Indoor air quality suffers, heightening allergy symptoms and allowing for higher levels of contaminants.  Additionally, clogged vents can result in decreased energy-efficiency.

Westland Heating and Air Conditioning has the experience and knowledge necessary to help you understand your North Olmsted HVAC system better. For all your HVAC needs,  call us today!

Air Conditioner Fins: Everything You Need To Know For Your Avon AC System

Monday, August 13th, 2012

What Are Air Conditioner Fins?

There are two types of air conditioner fins: condenser fins and evaporator fins.  Each performs a similar job of allowing air to flow smoothly through and out of an air conditioner, while each does this in a unique way.

Compressor fins are located on the outdoor portion of an air conditioner near the compressor is something that looks like a grill with metal fins all along it.  These air conditioner fins are a part of the condenser that assists heat in moving away from the air conditioner so that the heat disperses more quickly.

Evaporator fins are located on the evaporator and as it extracts heat from the air the metal fins help with the thermal energy exchange process that occurs with the surrounding air.  Air is blown across the evaporator fins where it is cooled and then sent from the air conditioner through ducts and vents and into various rooms.

AC Fins: What to Do With Bent or Clogged Condenser and Evaporator Fins

Because they are so delicate, AC fins whether condenser fins or evaporator fins can bend easily.  With normal use air conditioner fins can also get clogged with dirt and debris.  When condenser fins or evaporator fins are bent or when they get clogged it causes a major restriction in air flow that would usually pass through the air conditioning system, which means a decrease in efficiency for the entire AC.  When an AC has to work harder to create the cooled air because of less air flow, it can mean higher utility costs and an air conditioning system that will wear out more quickly because of overuse.

As air conditioning specialists in Avon, Westland Heating and Air Conditioning can provide you with the AC fin solutions you need such as handling clogged air conditioner fins and fixing bent AC fins.  Contact us today and get your air conditioning system back up and working efficiently once again with our quality AC repair services.
