What to Consider When Purchasing a New AC System?

North Texas can experience average temperatures as high as 95 degrees Fahrenheit and have a record high of 113 degrees during the summer. Choosing the AC that best suits your needs becomes essential. Thank goodness, air conditioners are now much more efficient and versatile in maintaining your year-round comfort. If you are looking for AC for your home, consult an expert AC contractor in Arlington, TX.

Before Making an AC Purchase, Consider These Factors:


Sizing your new air conditioner capacity is an important part of choosing your next air conditioner. For an Arlington, TX. Home If it is too small, it may not be able to keep you comfortable in the hotter days of the summer or when there are additional loads like when you are entraining large groups of people. Oversizing your air conditioner can create short cycling which will use more power and will have shorting run times which can create humidity control issues.

There is no “rule of thumb” sizing that will work in all situations. It is always best to run a manual J heat load calculation to determine the correct size. A basic heat load can be done using on line real estate data and applying any new energy upgrades such as upgraded windows ort added insulation.

Energy Efficiency

Given the rising cost of electricity, buying an AC that can provide you with the best cooling while using the least power is imperative. When an air conditioner’s SEER rating is higher, it operates more efficiently and consumes less electricity.


Using proper installation protocols such as flushing and evacuating lines and coils to remove old oil, moisture, and other non-condensable from the refrigeration circuit will help ensure the longevity of the new equipment.

Pulling a city permit and having a city inspector come out to approve the installation will give you the peace of mind that the system was installed to the current code and is safe to operate.

Filtration and indoor air quality

It is important to have a good filter system to protect the equipment and to improve air quality. We recommend a 4” pleated or larger thickness filter as these are less air restrictive and cost less over the long run since they hold more dirt and so don’t have to be replaced as often as a 1”.

You can also add indoor air quality devices such as a photocatalytic air purifier that will also remove or neutralize viruses and other organic pollutants in the air.

Inverter or Non-Inverter AC

DC (Direct Current) power is converted to AC power by inverters (Alternating Current). Inverter air conditioners have higher switching frequencies, making them more dynamic. By varying the tonnage or capacity of the air conditioner, you are effectively allowing the compressor to operate variably.

This will essentially give you a system that has hundreds of speeds. Running at very low speeds in milder weather conditions which uses less power and has longer run times to better “condition” the air maintain more even temperatures and removing more humidity.
In hotter conditions the unit will ramp up to higher capacities to remove more heat when needed.

A standard non-inverter system will run at one or two speeds. These systems will cost less but are also less versatile. They are still a good option and will do the job they are designed for for those that can’t justify the much higher price of the inverter systems
