When you notice your home getting a little hotter than normal, first check the thermostat settings. If the thermostat is set to cool, check the temperature setting to be sure someone hasn’t changed it. If it is off, set to heat, or set for constant fan (sometimes simply labeled “on”), switch it back to cooling operation. After the system kicks on, wait a few minutes, then check for cold air blowing from the registers. If not, move on to the next troubleshooting tip – checking the air filter.

Heat Pump vs. Air Conditioner: What’s Best for Your Home?

This is the “fuel” of your system, absorbing the hot air from yourhome and releasing it outside. If you’re still having problems with your AC, the next thing to do is look for signs of water leakage. Water leakingfrom your unit can mean there’s a blockage within the system, which could be caused by anything from a closedvent to a dirty, clogged air filter. During a scorching Canadian summer, the last thing you need is a problem with your air conditioner. But whilesome issues are definitely best left to AC repair professionals, you’d be surprised how many can be solved with asimple fix — saving you both time and money. We’ve put together a handy guide to the most common ACproblems and how you can solve them yourself at home.

And it can be especially frustrating if you have an AC running but not cooling. The evaporator coil is located in the outdoor unit of your HVAC system. It’s responsible for absorbing the heat energy from the warm air inside your home. It then works with the condenser coil to cool the air and return it to your space. Central AC units rely on easy access to circulated air to return refrigerated air to the house. These air returns have filters to prevent dust and dander from being recirculated into the house.

Dirty filters can severely restrict airflow, making your AC work harder than it needs to. Low refrigerant levels or electrical issues can also disrupt the cooling process. Understanding these common problems can help you take quick action and prevent further complications. In order for your AC unit to work properly, refrigerant is needed. This is a chemical that flows through both your indoor and outdoor systems. The primary goal of refrigerant is to extract the heat and humidity from the indoor air before it goes outside.

Fixing problems with refrigerant leaks is an air conditioning repair that a trained HVAC technician should perform. A standard 1 inch air filter should be changed about once every month. Changing the air filter not only gives you cleaner air, but it also ensures the proper air flow in your AC system. If the air filter becomes clogged it may be the reason your AC is not cooling your home.

You can get comfort and energy upgrades at no (or very little) upfront cost if your home qualifies to work with Sealed. You need to inspect your air conditioner for unusual sounds or smells. When your AC is not kicking on at all, it often is due to an electrical issue—it’s likely your AC isn’t getting the electrical current it needs to operate. If you tried all the above and your AC still won’t turn on, it’s time to call in the pros.

Should you turn off the AC if it’s not cooling?

Unlike the other fixes above, this isn’t a typical DIY job. It requires safety gear, and getting it wrong may mean having to replace the AC unit altogether. Another problem that can cause your air conditioner to run but not cool is a frozen evaporator coil. But in short, turn your air conditioner off if you have a frozen AC. Allow your system to run on "fan" only until the coil is no longer frozen.

Check out the answers to some of the most popular questions about air conditioners that aren’t working or cooling properly. Sometimes, these coils get clogged, freeze up, or are blocked by dirt and debris. You can clean your AC coils yourself, but replacing them is a job best left to the pros.

Next, clean out the condenser, evaporator, filters and coil. If these are dirty and clogged by debris, air flow within your unit may be restricted, which can severely affect the efficiency of your unit as a whole. Air conditioning systems can sometimes be fickle, with a variety of components working in tandem to provide that cool relief on a hot day. When your AC fails to deliver cold air, it’s a clear indication that something’s amiss. The reasons can range from simple fixes like a dirty filter to more complex issues such as refrigerant leaks or compressor malfunctions. Pinpointing the exact problem requires a systematic approach, and understanding common culprits can guide you in the right direction.

The compressor is part of the equipment that is outside of the house. It is surrounded by coils that the HVAC system uses to cool the air. They can become dirty from dust in the air, tree sap, sticks, leaves and animal activity, among other things.

If this AC problem is not dealt with properly, running an AC that is not blowing cold air might put your whole AC in danger. When central AC is not blowing cold air, for example, you want to shut it off to prevent further damage to a $3000+ unit. “When the system is completely out of refrigerant, modern units will activate an ‘LPS’ (low-pressure switch) that will shut the unit off to protect the compressor. You can tell this is happening when there is air coming out of the vents, but it will not be cold, and the outdoor unit will not be running,” says Ault of Frontdoor. One of the most common causes of AC cooling problems is leaving a window or door open somewhere in yourhome.

This draws heat out of your home and releases it outside, which helps to cool the air indoors. If the unit or its coils are blocked with dirt, grass, or other debris buildup, you may find that your home isn’t cooling properly. An air conditioner not cooling your home properly can lead to discomfort, reduced air quality, and other issues. There are many reasons why your AC unit may fail to operate as intended, ranging from incorrect thermostat settings to it being the wrong size.

If you haven’t cleaned the filter in your window or portable air conditioner recently, make sure you do and then check it periodically. For central AC systems, check the filter manufacturer’s recommendation for when to swap in a new one. In CR’s tests, HVAC (heating, ventilation, and air conditioning) filters last three to 12 months. HVAC systems use refrigerant (also called coolant) to cool hot air before sending it back to circulate throughout the home. ” In this case, the leak must be fixed to solve the problem, but homeowners won’t want to attempt this without a professional.

This results in an inadequate amount of cool air being produced. If your refrigerant turns out to be low, check your system to see what kind of refrigerant it uses, and keep that in mind when getting estimates. If you have an older Freon-based system that is being phased out, it may be time for a central AC unit replacement.
