Let’s face it: Summer in St. Louis is HOT. Sky high temperatures in the most sweltering months cause HVAC systems to work overtime, which means we get a lot of calls for air conditioner repairs. When your AC starts acting funny it’s hard to know when to call a professional, so here is a list of some things to look for as the mercury rises.
5 Frequent Reasons for Air Conditioner Repairs
Some home air conditioner repair calls are due to air not getting cool enough while some are because the AC quits all together. Here are some of the most common problems we see.
When cool air isn’t blowing out as hard as it should, look for frost around the air conditioner coil. A clogged air filter, coil or or blocked ductwork can lead to air flow problems that cause your coil to freeze. Sometimes the solution is a new filter, but sometimes it’s necessary to have an HVAC professional clean your coil or ductwork to allow more air to flow through.
When your air conditioner has the right amount of refrigerant, it’s able to keep your home nice and cool. If you only feel room temperature air blowing out of the vent, refrigerant levels could be low which means there’s a leak somewhere. You may be able to see ice building up on indoor coils and water dripping down. A licensed Crystal technician will be able to detect the leak and repair the line.
A capacitor’s job is to activate the motors that power the compressor and fans -- which then blow cool air through vents. If a capacitor burns out, the AC unit can’t operate efficiently so your home will definitely not feel as cool as it should. It’s very important to have a knowledgeable HVAC company replace the capacitor in order to get your AC running its best.
Of all the air conditioning repairs, we are always concerned when a customer calls to say they hear a screech, squeal, rattle or bang coming from the AC. While it could be something as simple as a loose screw, it could indicate a motor bearing problem, a motor blower issue, or a belt that’s on the verge of breaking. These can all cause your air conditioner to quit completely if they aren’t addressed promptly, so be sure to call us if you hear any of these noises.
A Unit that Quits
If your AC doesn’t come on at all, first check for a tripped breaker which can often happen after a summer storm. If that doesn’t do the trick, call Crystal. An older AC unit may be beyond typical air conditioner repairs and may need to be replaced, especially if it’s older than 10-15 years. This can come with a big price tag but remember that a newer, energy efficient unit will result in considerably lower monthly electric bills.
Regular Maintenance Can Prevent the Need for Air Conditioner Repairs
Many of the calls we get are simply due to a neglected system. When you schedule routine maintenance appointments with Crystal, we measure refrigerant levels, check for airflow problems and make sure all wiring and components are working well so we can detect potential issues before thy cause major issues. Even if you don’t have any current residential air conditioner repair needs, make an appointment to have your system inspected. It’s the best way to ensure your family stays cool all summer long.
