We are taking the following precautions due to the COVID-19 virus. All of our technicians have masks, glasses, latex gloves and shoe booties if they have to enter your home. Our technicians also have hand sanitizer and disinfectants that they use after every call.

If we are there to do maintenance and we don’t have to come inside your home to get to the equipment, we are asking homeowners to adjust the thermostat for us so we can do the system maintenance without entering the home. We will not be shaking hands and will keep our distance from customers.

Replacing Your Cooling System? Weigh These 6 Features, In Addition To The SEER Rating

When you are looking for a new cooling system, the best place to start is with the seasonal energy efficiency ratio, or SEER rating. This number is usually between 6 and 25 with the more efficient units having the higher number. But what if there are two models that have very similar SEER numbers and price points? That’s when you need to look at six other factors.

  1. Check to see if the unit has a thermal expansion valve, often called a metering device, which regulates the flow of refrigerant through the unit. This, coupled with an energy efficiency rating (EER) higher than 11.6 will assure that the cooling system will continue high-efficiency operation even when the temperatures reach into the triple digits.
  2. See if the unit has a variable speed air handler. This unit operates differently than a standard on/off blower, by allowing the blower to operate at several different speeds to reduce uneven temperatures and lower the noise level. The variable speeds will also reduce energy consumption, decrease humidity and increase the effectiveness of filtration units.
  3. Look for a fan-only switch so you can keep air circulating in the home without having to run the refrigerating portion of the unit.
  4. Check if the cooling system comes equipped with an automatic-delay function that turns the fan off a few minutes after the compressor unit turns off.
  5. Another option that many new cooling systems incorporate is a filter change indicator light. This light can be set to turn on after a set number of running hours. Some units combine this option with a filter air flow sensor that will light the indicator once the airflow efficiency falls below an acceptable level.
  6. Ask to hear the unit running. This will give you an indication of the noise level you can expect when it runs in your home.
