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.
Incorrect Thermostat Settings
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.

DIY Fixes vs. Professional Repair
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.
Check Your Ductwork
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.
1 AC Blowing Cool Air but Not Cooling House
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.
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.
We rely on window air conditioners to keep us cool when temperatures climb. Consumer Reports expert John Galeotafiore explains how to maintain a window AC unit to ensure cool, clean air throughout the summer. If you have a forced-air heating and cooling system, regularly vacuum the registers to remove any dust buildup. Make sure that furniture and other objects aren’t blocking the airflow through your registers. Check the seals around your window AC to make sure hot air isn’t getting in and cold air isn’t seeping out. Reseal around your unit with weather stripping if necessary.
Buy a more powerful air conditioner.
This can result in a serious clog, which can lead to a system malfunction. While this can cause your unit to blow warm air instead of cold air, it can also decrease your energy efficiency and even result in a system shutdown. No matter which type of air conditioner you have, a clogged air filter restricts airflow, decreasing efficiency and reducing the unit’s ability to cool the air effectively.
You Have a Dirty Air Filter
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.
Before performing any do-it-yourself (DIY) air conditioner maintenance, ensure that the unit is completely powered off. This can be done through the exterior shutoff box or your home’s breaker box. Repairing an air conditioner can cost anywhere from $100 to more than $1,000. To avoid pricey repairs, it’s important to prioritize AC repair and maintenance. Fortunately, there are a few tasks you can tackle on your own. A professional will evaluate your home’s size and provide the best options for your cooling needs and budget.
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.
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.
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.
