Why does my AC compressor stop after a few minutes?

If there’s something wrong with your AC that makes it shut off after just 15 minutes, it’s usually one of these issues: Unit is overheating. This often means there is simply a buildup of grime inside the compressor unit, but it could also mean there’s a refrigerant leak or have other causes.

Basic Maintenance

1. Clean Your Filter. First, turn off the power to your HVAC unit.
2. Clean the HVAC Interior. Next, clean out the condenser, evaporator, filters and coil.
3. Check Your Electrical Wiring. Nearly 85 percent of all HVAC repairs stem from electrical problems.
4. Check Your Ductwork.
5. Check for Refrigerant Leaks.

Why does my AC compressor stop and go?

Your air conditioner may be short cycling because it is repeatedly starting up then overheating (and shutting down) due to a bad compressor, dirty filters, dirty coils, low refrigerant, or frozen coils. An overcharged system will cause liquid Freon to get into your compressor and cause it to malfunction.

How do you fix a short cycle air conditioner?

Fortunately, there are plenty of ways you can put an end to your air conditioner’s short cycling issues:

1. Check your air filter.
2. Check your thermostat placement.
3. Check your air conditioner’s refrigerant levels.
4. Replace the low-pressure control switch.
5. Check the compressor.

Why does my air conditioner keep stopping?

The reason behind your air conditioner turning on and off repeatedly could be as simple as a dirty air filter. A dirty air filter can restrict airflow into your air conditioner, to the point where the evaporator coils freeze up. This would cause the unit to shut off prematurely. Take a look at your air filter.

What temperature should the air be coming out of my air conditioner?

If the AC system is operating correctly, then the air coming out of your vent should be about twenty degrees cooler than the regular temperature inside. So, if you’re cooling it and the house is 80 degrees, then you would ideally want the air to be about 60 degrees. Have more air conditioner questions?

How do I know if my AC is short cycling?

But when your AC system is short cycling, it will shut off before it can finish doing its job. In other words, if your air conditioner frequently shuts off before your set temperature has been reached, you have a short cycling problem.

What causes an air conditioner to short cycle?

When your air filter becomes too bogged down with dirt, dust and other microscopic particles, your air conditioner has to work harder to compensate for the lost airflow. These parts can overheat causing your air conditioning system to short cycle or even potentially break down resulting in costly repairs.

What is considered short cycling?

Short cycling is an HVAC term used to define a situation where a furnace or air conditioner turns on and off too frequently. The term “short-cycle” describes the period of time that your HVAC equipment is actually running, and the shorter this cycle, the harder your system needs to work.

Can a thermostat cause short cycling?

Your thermostat could also cause the HVAC system to cycle on and off rapidly, a process known as short cycling. Your furnace or central air conditioner spends a good amount of energy simply turning on and off, which is why you want yours to run for at least 15 minutes at a time before shutting off.

How long should AC Stay off between cycles?

How long should your AC stay off between the cycles? Well, your air conditioner should run for 15 to 20 minutes (2-3 times per hour) in a cycle & stop for at least 7 to 10 minutes between the cycles.

Why does my AC turn on and off every few seconds?

Got a central air conditioner that turns on and off every few seconds or minutes? This is called “short cycling” (because normally the AC has a regular on and off “cycle” that varies with the outside temperature.) Short cycling wears out the outside unit’s compressor.

Is it bad to keep turning AC on and off?

It may seem like a waste of energy to turn your A/C on and off, but doing so actually saves you a fair amount of money, Amann says. “Air-conditioning systems run most efficiently when they’re running at full speed,” she explains.
