Signs Your AC’s the Wrong Size

There’s nothing wrong with having a bigger air conditioner than your home needs, right? You cool down faster and you don’t have to run the unit for very long. The truth of the matter is it’s essential to have a unit that’s just right, neither too big nor too small. Advantage Air is here with signs you have the wrong size AC, which may lead to avoidable AC repair Fenton MO.

Continuous Operation

An AC unit that never shuts off may be too small for the home it’s in. The unit’s simply not big enough to cool a home adequately, so it never stops trying. This may lead to high energy bills and premature aging of the unit.

Constant Cycling

Rather than never shutting off, your air conditioner may frequently turn off and on. This may indicate a unit that’s too big, one too good and too fast at cooling your home. The issue with units that are too big is they strain themselves using so much unnecessary energy.

High Humidity Levels

Does it feel more humid inside your home than it does outside? ACs either too small or too big for a property cannot balance interior humidity levels properly. While humidifiers or dehumidifiers may help maintain comfort levels, you and your family may experience more relief with a properly sized AC unit.

Cold and Hot Spots in Your Home 

If the central part of your home feels cooler than rooms near the exterior of your residential property, you may have a larger air conditioner than you need. What’s likely happening is the AC quickly reaches your desired temperature in rooms in the “core” of your home but shuts down before distributing cool air to other rooms, creating cold and hot spots.

Understanding the Top Problems With AC Units

You rely on your air conditioner to keep your house comfortable in the summer and to prevent your air from getting too humid and causing mold problems. When your cooling unit breaks, sometimes it won’t turn on. In other cases, it just blows hot air, creates loud noises, or emits unusual smells. In all these cases, you need professional AC repair Fenton MO to address one of the following common problems.

Broken Thermostats

Your thermostat regulates your interior temperature and switches your system between heating and cooling services. If it’s in direct sunlight, out of batteries, or full of dust, it can’t perform these tasks.

Clogged Filters

Your HVAC system relies on filters to keep your air free of debris and particles as it circulates. If these filters are clogged, though, air can’t pass through them, causing your system to blow hot air or shut down completely.

Blocked Drains

Your AC unit’s drain line allows any condensation to leave the system without causing electrical damage. As time goes on, dust and lint block the entrance to your drain line, allowing water to leak into the rest of your unit.

Refrigerant Leaks

You also need a maintenance service if your refrigerant leaks from its compartment into the electrical system or filter. Some leaks are minor, whereas others overwhelm your entire system.

Broken Compressors

When your compressor overheats, it can’t use its coils to distribute refrigerant to the rest of your AC. Then, the rest of the AC unit overheats, and the entire system fails.

Breaking Down Common HVAC Noises and What They Mean

You may not pay much attention to your HVAC system as long as it works, and no one could blame you for that. It’s when your unit makes odd noises and you fear you need AC repair Fenton MO, that you pay more attention to your heating and air conditioning system. To help you understand what’s going on, here are common noises heating and AC units make and what they mean.


If you ever hear rattling coming from your unit, it may mean a part’s come loose or the motor sustained damage. Check your exterior unit’s doors and panels to see if they’ve detached. You may also have debris trapped in a mechanism. If you think your unit has a loose part, turn it off ASAP, so nothing comes disconnected or breaks.

Screeching or Squealing

Your unit may one day sound more like nails raking down a chalkboard. If so, you could need to get a new belt or repair the motor bearings. Squealing and screeching often signify worn-away or breaking parts. Much like rattling, you may need to turn the unit off to keep damaged parts from not working at all, which may result in an expensive repair bill.


Occasional thumping coming from your HVAC unit is normal, as it means the appliance’s powering down. It’s when you hear thumping around the clock that you should take notice. You could have damaged compressor springs if the sound’s coming from outside, or you may have a loose blower fan or broken ductwork seal if you hear the noise inside your home.


When your system sounds like a hive of bees, you may use it too much, which could force it to freeze up. Buzzing may also indicate a refrigerant leak. Either way, shut your unit off for an hour or two and start it again to see if that helps.

No matter if you know the source of noise in your HVAC or not, have an experienced technician examine it. Contact an Advantage Air representative to schedule an appointment.
