Airflow in a central air system

Have you ever wondered what happens to the air that is cooled and then dispersed throughout the home through your air conditioning ductwork to the supply air registers or vents?  Your A/C company representative can tell you in detail, but here's a quick overview.

That air must go somewhere, so in order to run the air conditioner most efficiently, the air is picked back up through a centrally located return air register with an air filter in it.  The filter cleans the air before it comes into contact with the wet surface of the evaporator coil, and inhibits your airflow causing problems.  From there, it is sent back through the ductwork.

As the air is cycled through the evaporator coil again and again, it is more easily cooled, which allows the unit to operate less frequently thereby using less electricity.  The longest a unit will generally run is when it is first turned on after a day away from home.  Once the desired temperature is reached, the unit will only cycle occasionally to quickly cool the air.

If you don't seem to have enough air coming from your vents, call your A/C company.  They'll send a technician to help as soon as possible.

Split System Air Conditioning and Heating Units

In San Antonio, as a matter of fact, throughout Texas and the whole United States, air conditioning and heating units are the norm in any home or business. In certain parts of the country, one will notice different types of cooling and heating systems used because they are most safe and economical. In Texas, the predominant unit used for home air conditioning is called the split system air conditioner.

A split air conditioning system is just what it sounds like it is.  It's a unit with both outside and inside units.  The outside unit is called the condenser.  The inside unit is called the air handler.  The two units are connected by control wiring and copper tubing.  All Seasons Comfort's expert technicians are adept at split system repairs and installations.

Call All Seasons Comfort now to have a representative check your split system air conditioner out.  We'll be happy to repair it or install a new, high efficiency split system.

Heat Pumps

A unit known for its efficiency while heating, is the heat pump.  While a resistance heat element (which essentially uses a toaster-like burner) uses a lot of electricity to heat a home with resistance heat, the heat pump uses what is called a reversing valve to simply reverse the flow of the refrigerant through the central air unit.  This heats a  home and uses approximately 1/3 of the electricity.

A simple way of putting this is to think about your air conditioner in the summer.  It blows cold air inside and warm air outside.  When the reversing valve kicks in during the winter, cold air is blown outside and warm air is blown inside.

Ultimately, it's up to you, the homeowner to decide whether you want a heat pump installation performed at your home.  Usually, making an educated decision is based on what you hear from your air conditioning contractor.  

Make sure your air conditioning contractor answers all of your questions by using easy to understand terminology.  It does you no good whatsoever to have your air conditioning contractor talk over your head in an effort to impress you.  Force him to use real world examples to paint an easy to understand picture of what he is talking about.  Then make your own decision as to whether a heat pump is the right choice for you.

Home Warranty Work

The professionals at All Seasons Comfort perform Home Warranty work.  So, we meet people on a regular basis who need residential air conditioning service.  Sometimes we aren't able to perform the work because we have strict guidelines to adhere to by the Home Warranty company.  

Please do your due diligence, and read your contract carefully, ask as many questions as you can, and learn all about your home warranty and its requirements.  Don't take it for granted that you will get the necessary residential air conditioning service you need for next to nothing.  

For instance, if you don't have your air conditioning and heating system maintained and serviced annually at the very least, sometimes twice a year, the home warranty companies are in a position to deny the work you need.  It makes many people angry, but the home warranty contract tells you it's necessary to have your air conditioning and heating system maintained in order to receive their services.  Please do your part to maintain your unit and your contract, so your All Seasons Comfort professional does not have to deny coverage of your home warranty service.

Don't be afraid to ask for a particular HVAC contractor when you call with an issue either.  If a good HVAC contractor performs work for you at one time, request that contractor next time.  Home Warranty companies screen their contractors, but your level of satisfaction comes from you.  To make sure you are happy, make the request.

The Importance of Having the Correct Size Air Conditioning Unit 

Sizing your air conditioning unit correctly is critical in a home.   While it's obvious what will happen if you undersize your air conditioner, the problems with oversizing an air conditioning unit aren't as straightforward.

To minimize energy usage, the experts at All Seasons Comfort strive to put the smallest air conditioning unit in your home that will effectively cool it.  

"Why don't you just put the biggest unit in my house?  I will pay for it, and I want to be cool in the summer."  All Seasons technicians  have heard that line before.  The fact of the matter is, though, there are reasons for not putting a larger air conditioning unit in your home.  

The humidity level is the biggest reason for sizing your unit exactly.  You see, if we were to put a larger unit in your home, it would only run for a short period of time to cool the whole home. That short period of time isn't enough to draw the humidity out of the air in your home.  Humidity control is a secondary function of an air conditioning unit.

Having a large air conditioner in a home sounds like a great way to cool your home quickly and effectively, but there are issues associated with having an oversized unit in your home. These issues can even cause health problems for family members sometimes.  Read more about it in the Ezine article linked to the title of this article above. - return to top -
Insulation and Load Calculations

The insulation in your home plays a big role in what size AC Unit is used.  At All Seasons Comfort, we perform what are called load calculations to help decide what size unit is best for your home.

A load, or Manual J calculation is a mathematical function used to calculate the R-Value of your home.  The R-Value is a measurement of thermal resistance.  The lower the R-Value, the less resistance your home has to heat entering and exiting the home.  When you have a very low R-Value, you usually need a larger unit, and your unit will cycle on and off far more often than normally. As you add insulation to your walls, ceiling and other places, your home's R-Value increases. This allows your unit to heat or cool your home quicker, cycle on and off less often and save money on utilities.
