Tampa Air Conditioning Tip: Landscaping, Your AC, and Saving Money!

Monday, April 30th, 2012

Who knew that proper landscaping of your home could save you money?  It’s true!  During those hot, summer months all we want is respite from that heat, and maybe a cool drink to sip.  If placed in direct sunlight, our Tampa air conditioners will work harder and more frequently than we would ever want to in such direct heat.  This is the time to prepare for the inevitable by giving the AC a break while at the same time saving money on utility bills.

Inspect, prune, and pay attention!  Get out in that garden and have a look at that AC unit!

  • Cut back any overgrown bushes or plants nearby, and remove any weeds growing near or over the AC unit, in order to ensure proper air circulation is maintained in the space immediately surrounding the AC unit. It might even be prudent to place stepping stones or cement in the foot of space immediately surrounding the unit, to keep a good barrier between the unit and surrounding foliage.
  • Pull out that green thumb and plant some flowers or greenery surrounding but not too close to the AC unit, making it a part of the yard’s landscaping, rather than an eye-sore which stands out.
  • Get your air conditioner under the shade.  This can be done simply by adding trees or tall bushes near the AC unit, protecting it from the blazing sun.  AC units can also be moved to the North side of a house or other building, making sure they are under the shade during the heat of the day.  Ensuring an AC unit is in the shade can mean not only saving approximately 5% on cooling bills, but can also increase the energy efficiency of the air conditioning unit by upwards of 10%.
  • Add trees or tall foliage all around a property to provide shade directly on the home or building, which can additionally contribute to overall cooling of the yard and buildings being cooled.

Proper landscape maintenance near, upkeep of, and airflow to an air conditioning unit ensures that there is reduced wear and tear on your Tampa air conditioner, helping it to run more efficiently for a much longer period of time.  Pay attention to your AC unit and it will provide a great service for many years.

Tampa Air Conditioning Guide: AC Problems You Need A Professional to Fix

Monday, April 23rd, 2012

In a hot climate, it’s great to be cool. Our Tampa air conditioning lets us sleep and helps us be our best through the hottest days.  It’s such a part of our lives that it’s easy to forget that our air conditioners must be regularly maintained.

Some things are easy for the homeowner.  Other repairs are complicated, technical and require a professionally certified HVAC company like Air National to accomplish.

Doing the Basics

For window mounts or the big units on the side of the house, regular cleanings and a filter change should be a part of every season. It’s not hard to remove the cover and replace the panel of webbing that catches lint and other particles out of your conditioned air.

Some warm water and a good shot of compressed air gently on the exposed fins will help to increase the longevity of the unit.  Be careful not to put pressure on the fragile fins and coils or use hot water that could cause corrosion.

Make sure the drain is clear, always cover the unit or store it away when more naturally cool temperatures take over and you’ve got conditioned air and relative peace of mind in the years ahead.

Big Problems

Without the regular service, however, an air conditioner begins to work much harder to produce the same amount (or less) of cool joy and parts begin to break down.  With total neglect, the unit itself may need replacement much sooner than was promised when you paid for it. These are repairs that could be avoided and require a Tampa air conditioning professional to make.

The key ingredient to cooling is a chemical called a refrigerant (most often Freon) that is capable of transforming rapidly from gas to liquid and back again at low temperatures. This runs through two intricate tubes, a compressor, and a critical expansion valve that controls the process.  It is a delicate and complicated process that calls for expertise and the right tools, especially since the refrigerant is considered hazardous and requires special handling.

When the air gets stuffy, it could be that the fan is the problem.  Belts could be worn, loose or broken.  The motor may be low on oil and is stained to the breaking point.

If mysterious signs of water or mold are showing up on the inside of the house near the unit, there could be a problem with the condensate that is released with the heat when air is cooled.  This could be a simple or complicated fix, but should be checked out professionally to ensure all is well.

Tampa Air Conditioning Question: What Are Thermostatic Expansion Valves?

Monday, April 16th, 2012

The thermostatic expansion valve, sometimes known as a TEX, TEV or TXV, is a critical piece to influence the efficiency of Tampa air conditioning and refrigeration units.  A tiny sensor controlling the evaporating phase of process, the valve can have a big effect.

Cool air is manufactured by a re rapid movement of a refrigerant between liquid and gaseous states.  Compound chemicals that are able to do this at a low temperature are compressed and expanded, absorbing and releasing heat at different points along the way.  The TEV controls the flow of the refrigerant into the evaporator coils according to the temperatures of the various ingredients.

Cool Air 101

To condition air, the refrigerant, most often freon or another fast acting, low temp compound, evaporates into a gas that runs through a coil and absorbs heat.  Passing through a compressor, the freon condenses under pressure back into a liquid again and releases the heat, becoming cool enough to chill a party.

Too much freon in the evaporator tube and the pressure is not low enough to expand to gas and absorb heat, working inefficiently for no gain.  Too little freon and the conversion is also ineffective by not reaching the density needed to condense.

There are four types of valves with different benefits for different types of cooling environments.  With its ability to adjust minutely to changing conditions, the thermal expansion valve creates the perfect mixture of pressure and freon for more complicated systems.

At the Starting Gate

An interactive device, the valve senses the evaporator pressure and temperature and adjusts the flow of the refrigerant so as to maintain a given “superheat”, the differ­ence between the refrigerant vapor temperature and its sat­uration temperature.  By controlling superheat, the TEV keeps nearly the entire evaporator surface active while not permit­ting liquid refrigerant to return to the compressor.

Some valves operate on an electrical impulse from sensors that can measure the temperatures.  Others are open all the time.  The thermostatic expansion valve actually utilizes the pressure between the two sections to open or close itself, regulating flow based on the very same pressure it is designed to moderate.

Like the buildings they comfort, large Tampa central air conditioning systems are varied and diverse.  There are nearly as many thermostatic expansion valves as there are units to receive them.

Tampa HVAC Tip: History of Heat Pumps

Monday, April 9th, 2012

Thermal energy is the natural movement from warm temperatures to colder temperatures creating energy in the change of temperature to the mass.  A heat pump typically is a device that moves the air (or other matter) in the opposite direction from its natural flow.

A heat pump often uses an intermediate fluid called a refrigerant which absorbs heat as it vaporizes and releases the heat when it is condensed,  using an evaporator to absorb the heat (or energy) from inside an occupied space and forcing this heat to the outside through the condenser. The key component that makes a heat pump different from an air conditioner is the reversing valve which allows for the flow direction of the refrigerant to be changed, allowing the heat to be pumped in either direction.

Timeless Technology

While mechanical movement of this energy, what we can actually call a pump,  has been a relatively recent invention,  the concept of this principal of physics has been in use since ancient times. Harnessing the power of geothermal energy (produced from the heat of the earth itself), natural hot springs “pumped” warm air into cool spaces in China and Europe thousands of years ago.

By 1852, Lord Kelvin had theorized the heat pump, but it took nearly 100 years to actually build one.  In the last half century, the technological advances have made heat pumps part of our lives in many ways.

First Pump

In the 1940s a man named Robert Webber was motivated to build the first known heat pump while tinkering with his refrigerator.  Accidently burning his hand on the outlet pipes of the cooling system, he was quite painfully awakened to an idea about the transference of heat.

Recognizing the freezer was constantly producing heat to cool its interior, he connected the outlet pipe to the storage tank of his hot water heater, extended that into a flow through pipes which heated air nearby, and  then used a fan to blow the warmth into another room.

The first heat pump was a crude, but effective method to provide comfort.  Creating a full-size version soon after, Wagner could heat his entire home.

Heat and Electricity

Today, Tampa heat pumps are built in many ways and shapes to heat or cool buildings of many sizes.  Combined with geothermal forces close to the Earth’s surface or potentially  deep within its fiery core, heat pumps are able to energize the turbines that can produce huge amounts of electricity.

As technological improvements are refined during this time of climate change and dwindling fossil fuels, heat pumps promise to play an important part in our futures.

Tampa Energy Saving Tip: Common Causes of Drafts in Your Home

Monday, April 2nd, 2012

If you find your Tampa heating and cooling bills are routinely too high, there is a common reason. Most of the time it is due to air leaks and drafts in your home that allow warm air to escape and cold air to enter and visa versa. Here are some common causes of such leaks and what you can do about them.

Sources of Drafts in Your Home

There are obvious drafts and less obvious ones. Let’s start by looking at the drafts that are most obvious:

  • Outlets and Plates
  • Windows
  • Baseboards
  • Attic
  • Air Conditioners
  • Weather Stripping

You can probably do a quick inspection of your home by yourself to check for these potential air leaks and find whatever may be causing the problem. The easiest way to check for drafts is simply to hold your hand up to the space and check for a change in air flow. You can also get a portable thermometer and see if the air temperature is different in those areas than it is in the center of the room or by the thermostat.

Insulation Inspection

Insulation is probably already in your home, but with time it can thin, get leaks or tear. Look for gaps in insulation or drafts coming through. A professional can inspect your insulation as well and make sure that it is still holding as much heat in as it was originally rated for. If you know that your insulation values are too low or that the insulation is particularly old, it may be a good time to have it inspected by a Tampa HVAC professional.

Making Changes

If you notice easy to fix drafts in your home, fix them immediately and you’ll be shocked by how much energy you save. For larger leaks such as your insulation, loose windows or problems with your doors, consider calling someone who is an expert in closing up air drafts and keeping your home both comfortable and affordable to heat and cool.
