First, we’ll start with what not to do. Please do not look up an online tutorial on how to fix your air conditioner and attempt repairs on your own. The problem is, an air conditioner that won’t cool may be acting this way for a number of different reasons, and only a trained and experienced professional can accurately diagnose what the problem is. HVAC installations and repairs should always be done by certified technicians to avoid costly errors. It’s important to call certified HVAC technicians for AC repair and servicing to ensure your system is properly and safely restored (though, we will get into possible causes below).

What should you do when your AC system won’t cool properly?

  • Check thermostat settings and confirm it’s set to “cool” with a lower setpoint than room temperature.
  • Replace or clean the air filter to ensure good airflow.
  • Clear debris and vegetation around the outdoor condenser unit.
  • If airflow is weak or cooling is inconsistent, suspect clogged coils or ducts.
  • Low refrigerant (due to a leak) often causes cooling loss and risks compressor damage.
  • Schedule a professional inspection for refrigerant, compressor, or electrical issues.

Our team is committed to providing dependable service in every HVAC installation and repair, ensuring you receive reliable and professional support from start to finish.

A lack of cooling coming from your AC is obviously an urgent problem though, particularly as we progress closer to summer. So what should you do if you notice this problem?

Have You Heard about the Daikin Inverter Air Conditioner?

April 22nd, 2019

First off, what is an inverter air conditioner? We are glad you asked!

In a standard air conditioner, the compressor has two modes: on, and off. When the system is on, it’s working at full capacity and consumes full electricity and energy that it is designed to consume. Once the temperature in your home reaches the desired temperature on your thermostat, the compressor shuts off.

Inverter technology, however, essentially functions like the accelerator in a vehicle. When the compressor needs more power, the inverter gives it more. When the compressor needs less power, the inverter gives it less. Why does this matter?

Are Germicidal Lights Right for Your Home?

April 22nd, 2019

uv-light-on-blue-backgroundAs summer approaches, so does humidity, and along with humidity comes some byproducts, like the development of mold and mildew. These can cause significant ill health effects, especially for people who already suffer from allergies or asthma.

One way to fight back against this is to have germicidal lights installed in your HVAC ductwork. These devices use ultraviolet radiation within your ventilation system to kill, or render inert, bacteria, mold spores, viruses, and microorganisms. They’re effective, don’t place harmful chemicals into the air, and require little maintenance.

What to Know About Damaged Ducts

April 8th, 2019

ductwork-being-repairedWhen you live somewhere like Lawrenceville, there’s a good chance that you already think about your air conditioner quite a bit. You’d understandably like to expect that it works efficiently and effectively throughout its lifespan. But what many homeowners don’t think about when it comes to their HVAC system is the “V” part of the equation—the ventilation that connects your cooling system to the outside, making the distribution of cooled air possible.

This ventilation system, known as your ductwork, is usually out of sight—hidden behind walls, beneath floors, or in your attic or crawlspace. Unfortunately, if your ductwork was installed by an inexperienced ‘professional,’ then there is a good chance that it has accumulated damage over the years. And if your air ducts are negatively impacted by anything like air leaks or poor connections, you could be experiencing problems that lead to poor HVAC efficiency and possible even AC repair needs.

The Unfortunate Power of a Dirty Air Filter

February 11th, 2019

persons-hand-switching-out-air-filterYou may have read in one of our other blog posts that we recommend changing your air filter every 1-3 months. We aren’t just saying this because it’s a nice thing to do—it will actually help you get the most effective and efficient use out of your heating and cooling systems as possible.

Why Maintenance Plans Are Totally Worth It

January 28th, 2019

furnace-receiving-professional-maintenanceHow do you prepare your heating and cooling systems for their respective seasons? Without argument, the best way to do this is by scheduling routine system maintenance. Maintenance tune-ups give our pros the chance to fully inspect your system, making any adjustments needed, cleaning the unit, and alerting you to any repair needs that exist. The best time to have this done is typically in the fall for your heater and in the spring for your air conditioner—but it’s actually more important that you have in done regularly, no matter the time of year.

HVAC maintenance is oftentimes forgotten, or at least, not prioritized by homeowners. We encourage you to not only schedule this service annually but to enroll in a maintenance program.
