Billy’s Bits of Wisdom

When it’s the dead of summer, and you want to relax at home, there’s nothing worse than a broken AC. However, a damaged unit is not always as apparent as a lack of cold air.

Here are some tips for deciding when to call in an HVAC technician from our own Billy Gouty!

Warm Air

This is perhaps the most obvious sign that something is wrong. We love our air conditioners because they provide cool relief from the intense Florida sun. So, when warm air is blowing at you, it can be frustrating (not to mention a waste of energy).

If you wave your hand over your AC and it’s either hot or lukewarm air coming out, it’s time to call in an HVAC technician. Warm air can either be caused by a failure in the compressor or a leak in the refrigerant.

Many people try to add refrigerant to their unit to address the problem, but this is unnecessary. Refrigerant is contained in a closed system, which means that a perfectly working AC will never need a refill. If the refrigerant is the cause, there is a leak, which should be fixed by an HVAC professional.

Lack of Airflow

Perhaps equally frustrating as your AC blowing warm air is your AC not blowing air at all (since that is its whole purpose!). Poor airflow could be due to several factors, and the first thing you should try is replacing your air filters. When debris builds up in the filter, it can hinder airflow.

Poor airflow can also come from a broken motor, broken fan, or other components’ failure. It can also be a sign of leaking air ducts, which need to be evaluated.

Bad Odors

Unless there is something stinky right outside your home, you should not smell foul odors coming from your AC unit. There are several reasons odors may come from the unit. One may be a frayed or burnt-out wire.

Another common cause of the odor is mold growth inside your unit. Mold thrives in damp, dark environments, which is certainly the case inside an AC unit, especially if there is a leak. Having mold inside your unit while it blows air into your home can be a health risk to you and your family, so don’t put off getting this looked at.

Strange Noises

Your AC will make noise, as is the case with many large home appliances. But when things sound off (use your judgment), there is likely an issue. Strange noises can come in many forms:

  • Clicking
  • Bubbling/gurgling
  • Banging
  • Squeaking
  • High-pitched hissing
  • Screeching

None of these noises are pleasant, and the cause of the noise will not be pleasant for your AC unit. Contact an HVAC technician immediately to reduce the damage done to your system.

Unusually High Energy Costs

If your electricity bills have doubled since last month, and you haven’t really changed your behavior, there is likely a problem. It’s hard to pin it exactly on your AC unit right away, but this is a common problem when an AC unit is broken or needs maintenance.

Try changing out your air filters to allow for optimal airflow. When filters get dirty, it causes the AC to work harder, therefore costing more energy. If this doesn’t work, contact a local professional.

Leaking Around the System

A leaking system is not only wasteful but can cause water damage if left untreated. The two liquids in your AC are refrigerant and water. Water accumulates naturally from condensation. When an AC isn’t functioning properly, it could leak refrigerant or pooled water.
