AC Unit Maintenance Procedures for St. Louis Area Homes
Ideally, you should have your central air conditioning system professionally inspected and maintained at the beginning and end of each cooling season. The maintenance steps will vary by model and manufacturer, but they typically include:
- Changing or cleaning the air filter
- Cleaning the supply plenum and checking for loose duct connections
- Lubricating blower motor bearings and pulleys
- Checking for refrigerant leaks and verifying proper freon charge
- Inspecting the condenser unit for debris and corrosion
- Cleaning the condenser and evaporator coil
- Cleaning the condensate drain and drip tray
- Inspecting and cleaning electrical connections
- Checking safety systems like breakers and pressure switches
- Verifying that the AC unit and thermostat operate properly at all settings
Between maintenance visits, you can help keep your central air conditioner running properly by changing the air filter as needed, cleaning the condensate drain occasionally and keeping the area around the condenser unit free of debris.
The Advantages of HVAC Maintenance for St. Louis Homeowners
Without preventative maintenance, your air conditioner will have to work harder to keep you comfortable as it struggles to remove heat through dirty coils and move air through clogged filters, increasing your energy costs. The advantages of regular maintenance include:
- Reduced cooling costs: With clean a evaporator and condenser coil, proper refrigerant levels, and all moving parts lubricated, your central air conditioner can cool more efficiently, reducing energy costs by up to 10 percent.
- Improved comfort: With the system running properly, it can cool and dehumidify your home more efficiently, improving your comfort.
- Lower repair costs: With regular inspections, problems can be caught early, reducing repair costs and preventing major problems that shorten the system’s lifespan.

Michael - St. Louis, MO
We selected Air Care to install new Hvac in February and have had a few things happen. Air Care has stood by their warranty and practice what they preach....service after the sale. I would highly recommend them, if you want a company that stands behind you after the sale.
Karen - St. Louis, MO
We had a problem with a new air conditioner. You never want this to happen, of course, but when it did, Classic Aire Care took care of it quickly and efficiently. Ultimately, they replaced the unit with minimal hassle and inconvenience to us. Both the technicians and the office staff were unfailingly helpful and courteous.

Replaced warranty evaporater coil
Emerson thermostat. Menu button was pressed. I explained to customer to push the menu button three more times to exit out of menu screen.
Follow up from August 6, 2018: check humidity in home. Main level humidity: 40 to 45%. Basement humidity 45 to 50%. I pumped down system and repaired leak at suction line connection near air handler. Evacuated system and topped off Freon.
Customer complaint: main level of home is humid. Wood floor in the dining room is buckled. I found humidity approximately 57% on main level, second floor, and basement. I checked for possible water leaks. Second floor system: I adjusted blower from “nom“ to “Lo“ and I eliminated 90 second blower delay for better dehumidification. First floor system: I adjusted blower from “NOM“ to “LO“. I set blower to “enhanced“ mode for better dehumidification. Found oil spot on floor under air handler. Found small Freon leak at suction line connection. Basement pressure is just slightly negative, causing infiltration of outside air. Recommend leaving basement door open about 2 inches for better basement dehumidification. Warranty no charge. Work suggested: need to return to repair Freon leak for first floor system. Warranty no charge.
