“How Often Should I Change My Air Filter?”

Your HVAC system’s standard air filter is in place to block allergens from reentering your home’s air and from infiltrating the interior components of your air conditioning and forced-air heating systems. When the air filter becomes too clogged, it decreases HVAC efficiency.

To ensure proper HVAC efficiency, you should change the air filter as follows:

  • 1’’ Filter – every 1-2 months
  • 2’’ Filter – every 4 months
  • 4’’ Filter – every 6-8 months
  • Electronic Air Cleaner – every 3 months

“Do I Need to Have My Air Ducts Cleaned?”

Duct cleaning is not an annually required service, but is a great way to improve your family’s health, and can increase the efficiency of your HVAC systems. If you or your household members are experiencing illnesses, or if you notice the air ducts and vents are filled with significant dust or debris, you should consider having them cleaned.

“What Is in the Air I Breathe in My Home?”

The air in your home is filled with the same pollutants as the outside air. In fact, these pollutants can be found in higher concentrations within the home, and require the right combination of indoor air quality solutions to resolve.

The most common contaminants and allergens found inside Plano and Dallas homes include:

  • Dust
  • Pollen
  • Particles from Household Cleaners
  • Mold Spores
  • Pet Dander

The particles from these pollutants degrade your indoor air quality by making the air in your home unhealthy. Fortunately, there are various products and services we provide to improve your home’s air quality. Be sure to speak to one of our Diagnostic Engineers or Installation Specialists about your options to help determine the best choice for your home.

“Why Is My Thermostat Display Blank?”

Homeowners rely on their thermostats to control the temperature and maintain a certain level of comfort. It can be understandably frustrating to find a thermostat with a completely blank screen, or one that seems to be registering the temperature incorrectly. There are a number of reasons this can happen.

If you’re having thermostat problems, please try the following troubleshooting tips:

  • Change the Batteries – Your thermostat’s batteries should be changed at least once a year.
  • Check the Circuit Breaker – If a circuit breaker was tripped, your thermostat may have lost power.
  • Check the Safety Switch – When there’s a problem with your HVAC system, like excessive heat or a condensation buildup, the safety switch can get triggered. The thermostat will shut off as a result. If this occurs, please contact our technicians as an inspection is required.

Your thermostat ages just like any other component of your HVAC system. Eventually, it will fail. If you’ve tried the above troubleshooting tips to no avail, it may be time to contact our pros about a potential upgrade.

“What Is My System’s Seasonal Energy Efficiency Ratio?”

Referred to as SEER, the seasonal energy efficiency ratio is how a central air conditioner’s efficiency is measured. Air conditioning systems with higher SEER ratings are more efficient. If you have an older air conditioner with a low SEER, it may be time to consider an upgrade.

“How Often Should I Add Freon to My HVAC System?”

Freon is a brand name given of refrigerant fluid within your air conditioner, and is currently being phased out. However, your air conditioning system is filled with enough refrigerant, or Freon, to last the duration of its lifecycle. It does not get depleted like gas from a car or oil from an appliance. Therefore, you should never have to add refrigerant or Freon to the system.

If you notice symptoms such as low cooling output or low airflow, you may have a refrigerant leak. The leak must be located and repaired by a professional, and at that point we will refill—recharge—the refrigerant level.

“How Does the R-22 Phase-Out Affect Me?”

Commonly called Freon, R-22 is the refrigerant previously used in all air conditioners. It is, however, found to be harmful to the ozone and will be completely phased out by January 2020. This means it will no longer be produced or imported. This doesn’t mean your AC system needs to be replaced, however if your air conditioner uses Freon/R-22 still, any repairs that require recharging can only be done using recycled Freon.

“When Does My HVAC System Need to Be Replaced?”

If you have an older air conditioner or heater—generally speaking more than a decade old—then you might want to consider an upgrade to a more energy-efficient system. An upgrade can save you money on utility bills and costly repairs in the future.

“Could My System Be Causing My High Energy Bills?”

Your HVAC systems contribute to approximately 50% of your entire energy bill each month. If you have an aging system, or your system hasn’t been properly maintained over the years, your bills could be a lot higher than you’d expect.

Make sure you entrust a qualified HVAC technician to inspect your system and repair any issues, so that it will work at its peak performance. You may also consider an upgrade to a more energy efficient model to keep your energy costs down. Consider too the installation of a home automation system, including a WiFi/Smart thermostat, to regulate temperature when you are away.

“What Can Be Done about Hot and Cold Spots in My House?”

There are a few factors that cause this type of uneven heating and cooling throughout your home.

Uneven temperatures can be caused by:

  • Improper HVAC Unit Size for Your Home
  • Poor Ductwork Insulation
  • Poor Attic Insulation

If you experience uneven temperatures in your home, be sure to have one of our experts check your system and insulation to determine the root of the problem. We’ll help you make an educated decision on how to proceed from there.
