Customer Review

"After two blistering 97-degree days, my A/C decided to stop blowing cold air. I called Crystal H&C, and later that same day, I was cool as a cucumber. I assumed my service technician, Darren Hahn, would be highly professional and well-experienced, but when he diagnosed my A/C problem walking toward the unit 10 feet away by the sound, I upgraded his status to Jedi Master HVAC Guy. He replaced a capacitor and had me up and running in no time! Afterward, he performed a cursory review of all system components and threw in some energy-saving tips as well. I considered their prices reasonable, and I will definitely be using Crystal H&C in the future." Rick R.   (see review)

Signs You Need Air Conditioning Repair Service

St. Louis summers can be brutal, so relying on our air conditioners to keep us cold is essential to us. Unfortunately, they break down, mainly when not regularly maintained and when that happens, priorities change. Here are the top 7 warning signs that you may need air conditioning repair service.

  1. Unusual Noises.  While low-level noises are normal for most air conditioning units, loud, sudden unusual noises can signal bigger problems with your unit.  Sounds like rattling or buzzing could point to a loose part while whistling or a grinding noise can be a bit more serious.  If you hear unusual noises, request a service call right away and don't' procrastinate.  Chances are a regular tune-up that will help!
  2. Blowing Warm Air.  If you feel warm air blowing out of your AC unit, first check the thermostat and make sure its switch to cooling mode. If it is, make sure it's set it lower than the temperature of your home.  Once you perform these basic checks, if your vents are still blowing warm air, it's likely you need freon is low or your compressor may be to blame.
  3. Frequent Cycles.   All healthy air conditioners should go through a routine cooling cycle.  And while your AC unit will turn on more frequently on the hottest of St. Louis summer days, it should not constantly cycle on and off.  If you notice frequent cycles, a quick air conditioning tune-up can most likely resolve frequent cycle issues.
  4. High Humidity.  Even in the stickiest of outdoor weather conditions, you should not experience high humidify indoors.  A well-tuned AC unit should moderate humidity levels, automatically.  If your unit isn't keeping moisture levels with a comfortable range for you, a simple re-calibration is in order.  You may also consider a dehumidifier.
  5. Insufficient Airflow.  Nothing is worse than an A/C unit blowing warm air than poor airflow.   If you're experiencing this in your home, chances are you have a clogged air filter, blockage preventing air from moving through your home's ductwork, or in worse cases, a broken motor.
  6. Water Leaks.   Air conditioners rely on refrigerant to cool homes. Sometimes units produce condensation as they operate so don't that concern you. What to look for in a water leak is signs of pooled water; an active leak.  You'll know it when you see it.
  7. Smelly Odors.  Last but not least, nobody likes a bad odor, particularly unpleasant odors that are coming from an HVAC system.  A quick diagnostics followed by a complete cleaning can most likely put an end to the embarrassing smell.
