Regular maintenance can help keep your air conditioner in good condition and reduce repair costs. Depending on the system and frequency of visits, a single visit may cost between $75 and $200. Annual contracts are more affordable for larger units. HVAC service costs can be higher in summer, but can be significantly reduced in winter. A typical central home air conditioner system will require a service visit that costs about $100. An annual service could cost anywhere from $150 up to $400.
If your evaporator is not working properly, please turn off the electricity to the system. This is necessary in order to prevent the unit's accidental turn back on. Next, wait until the ice melts. This can take as long as 24 hours. For ice formation on the evaporator coils, contact a licensed HVAC technician.
The central home conditioner's air filter may be found in one of many locations. This includes the indoor air handler which could be located in the attic or basement. The type and brand of your air conditioner will determine if the filter is horizontal or vertical. Some filters can be found in the blower box, while others are mounted in the return air grill.
First, turn off the AC. If this is impossible, you may use a dry and a wet vacuum to remove any obstructions in the drainpipe. Another common problem is a dirty filter in the air. This can block airflow to evaporator coils and cause water leakage. This is why you need to replace your filter as soon as possible.
You don't have to be comfortable with compressed air. A shop vacuum can remove dust and dirt from the coils. Be sure to follow all directions and protect your eyes. A qualified HVAC technician can help you if you feel uncomfortable cleaning the coils. This is an essential component of air conditioning repairs.
It's easy to replace the contactor of an air conditioner. Before you attempt this task, you need to be familiar with what to look for when replacing a contactor. One-pole contacts are the easiest to repair. It requires only one wire for power, neutral and common. You will find a plunger underneath the cover. If the contactor hums, it is likely that the coil has failed. If that is the case, try pressing the button using a stick. If the contactor has become melted, it will be necessary to replace it.
If your AC conditioner is not heating up to the correct temperature, or is blowing warm air out the supply registers it may be susceptible to ice accumulation. If this is true, it's best to contact a qualified HVAC technician for an inspection of your air conditioning system. Or, you can use a heat gun or hairdryer to melt the ice. Make sure your air conditioner is not clogged with ice during the cooling season.
