Air Conditioning FAQs: How Do I Determine the Cooling Capacity of My Central AC or Heat Pump System?

Monday, June 18th, 2012

For any type of air conditioning system in Phoenix, the cooling capacity is measured in BTU’s. This is important to know if the system doesn’t seem to be adequately cooking your home, and there are many different ways to check the cooling capacity of your AC system.

1. Air Conditioning System’s Age and Serial Numbers

An air conditioner’s age will usually give you a general idea for its cooling capacity, and if you aren’t sure, you can always check the serial number. Because serial number formats vary by the year the equipment was made, you can check to see how old an air conditioner is from looking at the serial number.

The first four digits of every serial number is the week and year the unit was manufactured.  For example, the serial# 1188E53294 on a compressor unit tells us that it was made between 1980 and 1990, and to be more exact, week 11 in 1988.

2. Air Conditioner’s Model Number

You should also look at the model number for your specific model because some manufacturers also vary how they assign each number in the serial number; however, they usually stand for tonnage or MBTUH. You can always call us if you aren’t sure how to read the serial number or model number.

3. AC Equipment’s RLA Numbers

RLA stands for “Rated Load Amps,” which means that it’s the manufacturer’s rate of the cooling capacity (also known as the draw) or load while it’s operating (minus the draw when you start the system). Most air conditioning compressor or condenser units will draw 5 to 6 RLA per ton of cooling capacity. You can check the data tag on the compressor for the RLA rating; however, this will need to be translated into BTUH for the total cooling capacity.

Toxic Mold Prevention For Phoenix Homes

Thursday, March 22nd, 2012

As a Phoenix resident you’ve likely heard the horror stories associated with the development of toxic mold in homes like yours where family members were sick for weeks or even months with no clear sign. Black molds and toxic fungi can cause a number of health problems ranging from respiratory distress to long term disease. So, the best response is to prevent it from developing in the first place, and maintain good indoor air quality.

Moisture is the Enemy

Mold needs one thing to grow – moisture. So, the easiest way to prevent mold from developing is to minimize the amount of moisture in and around your home. This is especially true in your attic and your basement. Any space beneath ground level is susceptible to leaks while the attic can leak due to gaps in the chimney lining or roof problems.

Mold develops on carpets, upholstery and other fabric and cloth spaces – so it’s a good idea to pay close attention to these spaces when in the basement or attic. In most cases, it is recommended that you stick with tile or wood floors anywhere that water has a habit of getting in.

Humidity should be removed from your basement with a dehumidifier as well to reduce the chance of sweating on concrete walls when the temperature drops outside. Sealing potential leaks and cracks in your roof will reduce the risk of other potential issues as well – dropping the total health problems faced by even the most innocuous of mold spores.

What to Do When Mold Appears

Obviously the goal is to stop mold from developing at all with dehumidifiers and air cleaners, but what happens when you see the telltale sooty black or gray patches on walls, carpets, or upholstery? Most mold abatement companies will start by sealing up the sources. Getting rid of mold is pointless if you cannot stop it from redeveloping. For that reason, you should work with whichever firm you hire to develop a clear and direct plan for removal of the offending mold.

Regular maintenance is recommended once mold has been removed to check for new growth. Even when mold is removed and the conditions that lead to the growth of the toxic substance are fixed, mold can come back. So, it’s important to check for potential regrowth on an annual basis.  If you have any questions about indoor air quality place call Cool Touch Air Conditioning & Heating Specialists.
