Things to Do Before Switching on Your A/C

Air Conditioning Installation

Have you ever wondered if you’re doing the right thing before turning on your air conditioning system in Ladue, MO? You surely don’t want your A/C to fail the midst of the summer. So here’s what you need to do before switching it on:

Air Conditioning

Examine Your Thermostat

Is your thermostat displaying signs of wear and tear? Consider an energy-efficient programmable thermostat to maintain your house at a pleasant temperature while saving money on other utilities. With a programmable thermostat, you won’t have to check on your A/C too often anymore.

Have a professional HVAC technician examine the thermostat’s location as well. It should be placed 150 cm from the ground, away from any heat sources.

Circuit Board

You may have turned off the circuit breaker for your outdoor air conditioning unit. You’ll need to turn it on again this summer, preferably 24 hours before turning on your air conditioning. It’s an air conditioner maintenance job that you can also do on your own. Contact a professional if there’s an issue with the circuit or if you’re not sure which one controls the outside unit.

Refrigerant Level

Be sure to check the refrigerant level. The refrigerant is an essential component of an air conditioner which evaporates and condenses throughout the cooling cycle. Your A/C refrigerant level will decrease because of leaks or even if it never gets used up. Before the refrigerant is filled up, the leak must be repaired.

Air Conditioning

Maintain Your A/C Drain

You can keep your air conditioning drain clean throughout the summer season by flushing one cup of chlorine bleach down it and then rinsing it with a gallon of water. Unfortunately, when dirt collects on the interior coil, the air conditioner drain pipes get blocked.

Replace Your Air Filter

Every three months or as suggested by the manufacturer, and certainly before starting a new cooling or heating season, you should replace your system’s air filter.

If you keep your air filter clean and unclogged, you’ll allow adequate airflow in your home. Inspect your air filter every 30 days if you use your central heating and cooling system. At least once every three months, change the filter (or clean it if you use the permanent kind). Also, double-check the filter before turning on your air conditioner for the season.


Your air conditioner’s outside condenser unit has sat inactive for months. As a result, it may be blocked with leaves, dirt, and other debris. You’ll need to get it cleaned and any extra water drained. Protect your condenser with a cover next winter.

Coils for the Evaporator

Evaporator coils in air conditioners are also known as cooling coils. They are responsible for eliminating heat from the air that enters your air conditioning system. It’s recommended to have the coils cleaned once a year; otherwise, they waste energy and create problems like a constantly running air conditioner.

Get Routine A/C Maintenance

You’re probably wondering why you need to call an expert for A/C maintenance when you haven’t even turned on your system yet. When you plan A/C maintenance ahead of the cooling season, you ensure that any minor issues are addressed before the air conditioner begins to operate nonstop.

You prevent minor issues from becoming bigger ones and jeopardize your comfort when you need it most—amid a Ladue, MO summer—by scheduling a maintenance appointment now.
