AC Maintenance in St. Louis, MO

What should humidity be in the house with air conditioning?

The ideal level of humidity for air conditioning should hover around 40-60% - too low or high can result in uncomfortable side effects. Too much moisture can lead to problems such as damp walls, mold and mildew, while too little humidity can cause static electricity, dry skin, and crackling woodwork. Having the right balance is an important component of managing indoor air quality. With regular maintenance and adjustments of your air conditioner’s settings as needed, you’ll be able to keep your house at the optimal humidity level all year round.

If you have dealt with humidity issues for as long as your AC has been in place, it may be improperly sized for your home.

How often do you need to add Freon to a central air conditioning unit?

Refrigerant should not need to be added to an AC system unless you have a leak. It is a closed system. If you have a leak, it’s important it is repaired before your AC is recharged, otherwise you will be paying over and over for expensive Freon, or Puron if your unit is newer than 2010.

How will I know if my AC system is losing refrigerant?

Several signs can indicate a refrigerant leak. You might notice that your AC is not cooling as well as it used to, the unit is running for longer periods, ice is forming on the evaporator coils, or you hear a hissing or bubbling sound coming from the unit. A professional technician can accurately check refrigerant levels and locate and repair any leaks. Low refrigerant not only affects cooling performance but can also damage the compressor.

What can cause my outdoor AC unit to freeze up, and what should I do?

Freezing of the outdoor unit (condenser coils) can be caused by several factors, including low refrigerant, restricted airflow due to a dirty air filter, or a malfunctioning blower motor. If you notice ice buildup, turn off your AC system immediately and call Vogel Heating & Cooling. Running the system while frozen can cause further damage. Do not attempt to chip away the ice yourself, as you could damage the coils.

Can regular AC maintenance help with allergies and indoor air quality?

Yes, regular AC maintenance plays a significant role in improving indoor air quality. Cleaning or replacing air filters removes dust, pollen, pet dander, and other airborne allergens. Additionally, cleaning the evaporator and condenser coils can prevent the growth of mold and mildew, which can also contribute to poor indoor air quality and trigger allergies.
