Our air conditioners keep us comfortable in the summer. A functioning air conditioning unit helps us avoid heat and humidity. When your AC doesn’t function properly, it’s time to call a skilled AC contractor in Wilmington, DE.

Possible Causes of Your AC's Sudden Failure to Function

Dead Batteries in the Thermostat:

Your air conditioner may be in perfect working order. Occasionally, the batteries on your thermostat may die. When the screen is blank and you are unsure of the cause, changing the thermostat batteries should be your first defense regarding heating and cooling in Bear DE.

Tripped Circuit Breaker:

Examine the breaker box. Reset any tripped breakers so you can examine the AC one more time. Remember overloading a circuit is a common reason why breakers trip. If the breaker trips once more, you should consider turning off additional equipment causing the issue. You could also contact an AC installation in Newark, DE, with experts to identify the problem.

An air conditioner won’t cool well if the refrigerant level doesn’t match the manufacturer’s recommendations. Call a technician to identify and resolve the issue if your system leaks. In 90% of low refrigerant situations, adding more refrigerant won’t add much improvement.

Blockage at the Outdoor Condenser Unit:

The outdoor unit should be kept at least 2 to 3 feet away from plants or backyard fixtures. Your house could be hot for other reasons, such as the style of outdoor landscaping and lawn maintenance.

The Thermostat is Outdated, Or the Unit is Too Small:
