There’s nothing like feeling brisk, cool air pass into your Hamilton Township home on an 85-degree New Jersey summer day.
At the same time, there’s nothing like the disappointment and panic that overtakes you when you realize your air conditioning unit is no longer turning on or producing cool air.
If the latter sounds familiar, Home Allegiance Heating & Air relays why this occurs and how to troubleshoot issues.
Faulty Thermostats Causing Temperature Malfunctions
Your thermostat constantly monitors your indoor climate while noting your temperature preferences. For instance, if you set your thermostat to 72 degrees, your unit turns on if your home surpasses this.
But what if it doesn’t?
→ In most cases, someone may have accidentally changed the temperature setting and all you have to do is reset it.
→ If that doesn’t work, troubleshoot it by replacing dying/dead thermostat or remote batteries that cause temperature fluctuations.
→ If cool air still isn’t blowing due to a thermostat that isn’t lighting up or responding, an expert should check the wiring.
Dirt Blocking Proper Airflow
Whether you have portable air conditioners or window units, dust and dirt can easily block airflow, causing your unit to overheat and shutdown.
The most common cause is dirty filters because the meshy surfaces quickly fill up with:
- Dust and lint
- Hair and pet dander
- Pollen
- Other airborne debris
Residents should change or clean filters on all HVAC systems every three (3) to four (4) months.
If you haven’t done so yet for the season, remove and inspect them after turning your air conditioning unit off.
If there’s a lot of buildup, toss and replace the filters, or use a gentle brush and mild soapy solution to clean the surfaces.
You should also clean air vents and ductwork if you have centralized air conditioners or hire professionals to vacuum deep within the chutes for optimal cleanliness.
Poor Heat Transfer Reducing Cooling Power
Cool rooms depend on your unit’s ability to transfer heat during the following process:
- Indoor air enters the vents and passes over the evaporator coils in the evaporator compartment
- Liquid refrigerant fills these coils, absorbing heat from the air and turning into a gas
- The hot gas travels to the outdoor condenser coils where pressure increases
- The coolant releases the heat outdoors and reverts to a liquid
However…
→ If you have low refrigerant levels due to a leak, you won’t have enough coolant to efficiently remove heat during a cooling cycle.
→ If dust or ice lines the coils, the refrigerant won’t optimally absorb heat, reducing transfer and absorption levels.
While you can open up your system and clean coils with a soft brush or blow warm air over frozen coils, professional intervention is key for leaks.
