While there’s a wealth of information on the internet about air conditioner issues, we wanted to get laser-focused in our approach. In this post, we’ll be going over AC issues that are unique mostly to central air conditioning systems. While variations of this advice might apply to systems like ductless mini-splits, this advice is geared solely toward central ACs.
Central AC systems, traditional heat pumps, and furnaces all use ductwork to transport air through the home. This means that even though most of the cooling/heating process happens at the point of the machine, all that energy can go to waste if the ducts aren’t in great shape.
- Duct Leaks: Ducts can form leaks for several reasons, but most commonly from tears or disconnects. Flexible ductwork is made of material susceptible to rips and tears, either through wear-and-tear or from vermin. Or, the sealants keeping ducts together can simply degrade and fall apart over the years.
- Dirty Ducts: We take great care to clean up the dust and dirt that accumulates in our homes, but what about the dust that ends up in our ductwork? As this dust builds up over the years, having it cleaned once a year is essential.
- Obstructions: Physical objects inside the ducts can obstruct airflow, thus hampering your AC’s efficiency. Insulation that has fallen off, debris from remodeling projects, vermin, and particularly large buildups of dust and dirt are common culprits.
All these problems are expected when it comes to ductwork, but they’re easily taken care of with the help of a professional AC repair service in Allen, TX.
Central air systems are responsible for cooling or heating the entire home. This means that, from the very start, the air conditioner that goes into the house needs to output the perfect amount of power.
- Unit Is Too Big: Bigger is not better, in this case. If the unit installed is too big for the home, then it will cool the home too quickly. This forces the AC to turn on and off rapidly, an issue called short-cycling that’s very taxing on your system.
- Unit Is Too Small: If you’re imagining the opposite of short-cycling, you’d be correct. A unit that’s too small won’t cool the home completely, causing it to run continuously without stop.
While we wish we could help, there’s little that can be done about improperly sized air conditioners. A replacement with a properly sized unit is the only way to fix these issues.
Bad Thermostat Installation
The thermostat is the control center for your air conditioner. If it’s inaccurate, the rest of your system won’t be able to act normally. There are some cases where a poor installation of the thermostat can make it run inefficiently. Compare this to zone control and ductless mini-split systems, which use individual thermostats in each room, making this a much less substantial problem for them.
Some examples of bad central AC thermostat installation include:
- In direct sunlight.
- Near the kitchen, where temperatures from appliances and cooking can affect it.
- Above or close to an air vent.
- The hallway.
- Near doors and windows.
