Air Conditioning Repair | AC Blowing Warm Air
A lack of cooling is a common cause forscheduling air conditioning repair.However, there are a numerous reasons that may be behind the AC blowing warm air. Before you callfor air conditioning repair checkthe following, the solution may be a simple fix:
Dirty Air Filter
Properly changing/cleaning the air filter isessential to the performance, and lifespan of the HVAC system. A clogged air filter will restrict the airflow throughthe system, causing premature wear and tear, results in a dirty coil (and theneed for coil cleaning), and can potentially cause overheating and a fire. Aclogged filter is a potential cause of the ACblowing warm air, so check it every 2-4 weeks even if it isn’t time tochange it.
A Tripping CircuitBreaker
The airconditioner requires electricity to operate. A circuit breaker in the home’selectrical service panel controls the power source for the AC. Breakers turnoff when an electrical overload occurs, or when a breaker fails. An electrical overloadcan be due to an overloaded circuit, such as when a power surge occurs. Otherpotential causes of tripped breakers include a short in the AC system, damaged wiring,and other causes. Contact your Cypress Heating and Air Conditioning technicianfor a consistently tripping circuit breaker.
Some AC systems have their own circuit breakersin addition to the one in the home’s electrical service panel. These can alsotrip when a power surge or problem occurs. Read the system’s owner’s manual asthe location varies, or contact
Check the Thermostat
Homeowners’ often take advantage of fresh, coolerair outside by opening a window and adjusting the thermostat from cool to off.Furthermore, some prefer to set the thermostat to manual fan to pull more airin.
The problem is when you forget to return thethermostat to its normal settings for cooling and the fan from manual toautomatic. If the fan is placed on manual rather than ‘auto’ it runscontinuously, and if the cooling function is off the result is the AC blowing warm air. When the AC is blowing warm air, check thethermostat first for the proper settings before calling for air conditioning service.
Refrigerant leaks are a common cause of the AC blowing warm air, and of the need for air conditioning repair. In a splitsystem, you will be able to view the refrigerant lines in the air return (the areawhere you change the filter). Remove the panel and inspect the copper lines, ifthey are frosted or iced over the unit is likely low on coolant due to arefrigerant leak.
The repair of a refrigerant leak requires theservices of a certified HVAC technician.It isn’t a DIY repair as complications occur due to overcharging orundercharging of refrigerant.
A Bad Compressor
The compressor is the main component of the airconditioning system, and when it fails, the options are to replace it or providea new air conditioning installation.The latter is typically the wisest option, especially when the system is 10years old or older.
Faulty switches, damaged wiring, and otherelectrical components are potential causes of the AC blowing warm air. TheHVAC system is comprised of numerous components, each dependent upon theother, and when one fails the entire system can fail.
Dirty coils are one cause of the AC blowing warm air. Not changing theair filter as required will lead to a dirty coil. Providing routine maintenancewill ensure all aspects of the system receive an annual inspection, and willenable the HVAC technician to providea professional cleaning when necessary. This ensures efficient operation,increases reliability, and helps to reduce wear and tear. A dirty coil is one potential cause of waterrunning onto the floor, causing damage to the home’s structure.
In a split system, the indoor component containsthe fan blower, and the system’s evaporator coil. As the coil sweats, thecondensation drops into an evaporator pan with a drain leading outside. Whenthe drain clogs, the evaporator pan can overflow, and has the potential todamage flooring, and the home’s structure.
