Frequently Asked Questions
What is the best air conditioner for my home?
Why is my AC leaking water?
- Clogged Condensate Drain Line. The most obvious is a clogged condensate drain line. When your air conditioner is working properly, it condenses water out of the air. This water then drips into your condensate drain line, which removes it from your home. If that line gets clogged, it can cause a backup into your house. Many homes have overflow lines that extend outside, but if you can see water dripping from your AC, even if it is outside of your home, it indicates a problem.
- Dirty Air Filter. If your air filter is dirty, it can block the airflow to the evaporator coil. The coil freezes up. When the coil melts, it begins to drip. This increase in water may be too much for your drain pan and cause it to overflow.
- Low Refrigerant. Low refrigerant results in lower pressure in the system, which can cause a frozen evaporator coil. When the coil melts, it begins to drip. This increase in water may be too much for your drain pan and cause it to overflow.
- Damaged Drain Pan. Designed to work with the normal condensate system, a drain pan catches the condensation. If the drain pan gets damaged, water will leak.
- Broken Condensate Pump. If your AC unit is in a basement, then it uses a pump to get the water outside. If that pump breaks, you get a leak.
Why is my AC icing up outside?
- Cool Summer Nights. A particular problem in a desert environment, cool nights can mess with your air conditioning system. Air conditioners are designed to work with certain ambient outdoor temperatures. You can use a programmable thermostat to keep your air conditioner from trying to operate when the outdoor temperature is below 60 degrees.
- Dirty Air Filters. Dirty air filters prevent the air conditioner from getting enough air. Without that air, humidity settles on the coils, where it freezes. So, if your system is frozen, one of the first things to do is to check your air filters. You can check to see if this is the problem by turning off your AC for long enough to thaw (1 to 3 hours), then turning on the fan for an hour. Replace your filters during that time. If your AC is back to normal after that process, dirty filters were the culprit.
- Low Refrigerant. Low refrigerant levels cause a drop in pressure. This allows the refrigerant to expand, which lets it become too cold, and the system freezes. If you have a coolant leak, you need a professional to find and fix the source of the leak and recharge the system.
Why is my AC blowing warm air and I have the thermostat set to cool?
- Are the air filters dirty?
- Is the evaporator coil frozen?
- Is your thermostat on the right setting?
- Is the outside unit getting electricity?
Why are all of my rooms cool but one room is hotter than the rest of the house?
- Replace dirty air filters.
- Make sure the vent is fully open in the room that is hotter. Shut vents a little in rooms that are too cold.
- Shut your windows.
- Inspect your air ducts for kinks, crushes, and leaks.
How much does a new AC install cost?
That depends on the size and type of your air conditioner. Costs range from around $2,000 to $10,000, with the average prices being just under $6,000.
