If you're hearing strange noises coming from your air conditioner, it may be time to consider replacing the unit. Unusual sounds can indicate that there is an issue inside the unit itself and, if a technician is not contacted to repair it, it could lead to more expensive service in the future. Additionally, if no cold air is coming out of the air conditioning unit, it could be due to a compressor fault. When you feel warm air coming out of the vents in your house, check the thermostat.
Make sure it's in cooling mode and adjust it below your home's current temperature. If the vents are still expelling hot air, the cause may be a restriction in airflow or a problem with the compressor. If insufficient airflow is a common problem in your home, an energy recovery ventilator can help exchange stale air for fresh air every time the system cycles. Zoning systems can also ensure that you get the right airflow and cooling power where you need it most. The air conditioner must go through relatively routine cooling cycles, regardless of the weather.
While you can expect the cooling system to turn on more frequently on the hottest days of summer, it shouldn't be constantly on and off. If you observe frequent cycles, contact a refrigeration expert for a quick tune-up of the air conditioner. But if this doesn't resolve the issue, it may be time to replace your HVAC system. During spring and summer, you can expect humid outdoor weather. But that doesn't mean you want to experience high humidity indoors.
The air conditioner should moderate humidity levels automatically. If your air conditioning unit is at least ten years old, be thankful that it lasted so long and start looking for a new unit. Air conditioners generally don't last longer than a decade. These signs are useful reminders of how to quickly recognize a problem and, in many cases, help to avoid replacing an HVAC unit entirely. Keeping your home at a comfortable temperature during the summer months requires many mechanisms that work properly.
If you experience any of these 10 signs, contact a professional HVAC technician. Trying to handle the repairs yourself can result in unnecessary costs if something goes wrong.
