There are several air conditioning problems that can easily be solved by the homeowner before calling for air conditioning service. An AC blowing hot air is a common complaint that may be caused by a number of issues. Before calling in an HVAC professional, troubleshoot your system with the help of these tips:
Check The Thermostat
It’s common to accidentally turn the thermostat setting to “heat” instead of “cooling.” Make sure your thermostat is set to “cooling” and turn it down 5 degrees. Wait a few minutes to see if changing the setting or lowering the thermostat did the trick.
Check The Outdoor Unit
Make sure the outdoor condensing unit is turned on. If so, check for debris, such as grass clippings, dirt and nearby plant growth, which can become trapped in the fins of your outdoor condensing unit and prevent proper airflow to your system. Hose down the unit to remove the debris.
Check The Air Filter
The air filter in your air conditioner prevents dust from building up inside your system. While the filter is probably not completely responsible for your AC blowing hot air, it can play a major part. When the filter becomes clogged, air doesn’t flow optimally to or from your unit. Turn off the power to your air conditioner and change the filter if it’s dirty.
Check for Ice
Ice buildup on either the indoor or outdoor unit may signal a refrigerant leak. Refrigerant is the chemical responsible for cooling the air in your system. Leaks must be addressed by a qualified HVAC professional due to the dangers of refrigerant to humans and to the environment.
If your air conditioner continues to blow hot air, contact an HVAC technician to inspect and repair your system. As always, planned annual preventive maintenance on your air conditioner can prevent a number of common problems with your system, including your AC blowing hot air, throughout the cooling season. It also increases system efficiency to save you money and extends the operating life of your unit.
Two essential monthly tasks that homeowners can perform to prevent problems like the AC blowing hot air are changing the air conditioner filter when it’s dirty and hosing down the outdoor unit to remove debris trapped in the fins.
Spring is right around the corner and New York homeowners are looking for a qualified HVAC professional to perform routine air conditioning service.
A yearly tune-up at the beginning of spring by a certified HVAC technician will ensure your air conditioner operates safely and efficiently all summer long.
Yearly air conditioning service extends the life of your air conditioner, lowers your cooling costs and helps prevent the need for expensive repairs. A comprehensive tune-up will include these essential points.
- Lubricate the moving parts of the system to reduce friction.
- Test the system controls to ensure your air conditioner starts, runs and shuts off properly.
- Measure and adjust the refrigerant and check for refrigerant leaks.
- Flush the condensate drain to prevent overflow, which can promote the growth of mold and mildew.
- Clean and tighten electrical connections for safety.
- Check the blower motor for wear and tighten or replace fan belts as needed.
- Check the compressor contacts.
- Clean the outdoor condenser coil to remove dirt and debris.
Air conditioning service shouldn’t stop there. There are several things you can do to keep your air conditioner operating optimally for the duration of the cooling season.
- Check your air filter every month and replace it when it’s dirty. A dirty air filter reduces the air flow to your system and reduces its efficiency. Keeping your air filter clean will not only extend the life of your system, but will also considerably improve your home’s indoor air quality.
- Keep your outdoor unit free of debris such as weeds and grass clippings from mowing.
- Hose down the outdoor coil every month to remove dirt buildup, which can make your system work inefficiently.
- Keep the area around your air conditioner clean and free of obstructions for easy access and to help prevent dust buildup on the interior of your system.
- Make sure your furniture isn’t blocking your supply and return registers, which can reduce the flow of air to your system.
- Don’t close off more than 20 percent of your supply registers in an attempt to save money on cooling costs. Doing so can impede the flow of air to the system and possibly result in overheating and other damage.
Neglecting your air conditioner can result in expensive repairs and higher energy costs. With a combination of professional and DIY air conditioning service, your air conditioner should last at least 15 years.
