Air Conditioner Not Working? Here Are Some Repair Tips

How To Fix Common Ac Problems 

An efficient AC unit is the key to staying in your comfort zone during the summer. Investing in our Club Membership Program is one great way to optimize your home cooling, but in between your pre-scheduled visits, you may notice some smaller issues that compromise your home comfort. Luckily, many of the problems homeowners encounter can easily be fixed by following a few tips from the experts. If your home comfort is suffering due to these common AC problems, here’s what you can do. 


Unit Cycles On and Off 

One of the most common AC problems homeowners deal with is short cycling. There are a few reasons your air conditioning unit starts and stops every few minutes. A faulty thermostat, dirty air filter, or refrigerant leak may be the culprit. To find the root of your problem, you’ll want to start by performing a quick inspection of each of these components. If your air filter is dirty or hasn’t been replaced in the past three months, go ahead and replace it. A clean filter is a crucial component of an efficient AC unit.


If this doesn’t mitigate the problem, try checking your thermostat. If you think your thermostat is failing, there are a few steps you can take to troubleshoot it. A blank or unlighted thermostat screen means it likely needs to be replaced. The location of your thermostat can also impact how it functions. If your thermostat is in direct sunlight, or if it is located on a wall with large openings or holes behind it, your temperature readings may be inaccurate. Before replacing your thermostat, try checking the settings, batteries, and circuit breakers first. If you have confirmed these elements are not at fault, then it may be time to replace your thermostat. 


The last reason your unit may be short cycling is if you have a refrigerant leak. If this is the case, you’ll need to repair the leak before adding more refrigerant to your unit. If you suspect a refrigerant leak, contact an R&D HVAC professional to help locate the source of the leak and facilitate the repair. 


A/C Blows Hot Air 

If your A/C unit is running, but blowing hot or lukewarm air, you are likely dealing with a low refrigerant level. Luckily, this can easily be fixed by recharging your system with new refrigerant by an R&D technician. Be sure to inspect your unit for leaks beforehand. If your refrigerant is leaking, refilling it will not solve your problem. 


A/C Running Constantly 

We know you want to keep your home at a comfortable temperature, but your unit shouldn’t be running constantly in order to do so. Your A/C unit’s thermostat is responsible for measuring the room’s ambient air so that it knows when to turn on to reduce the indoor temperature. If your thermostat is incorrectly measuring the room’s temperature, it will instruct your unit to keep running until it reaches your set temperature. Reaching this goal temperature can be impossible if your thermostat is faulty. 


Fortunately, this problem can be easily remedied by replacing your home’s thermostat. We offer a number of different solutions when it comes to system controls. From smart thermostats to zone control systems, R&D Plumbing & Heating has you covered.
