It is important to know when to call a professional, especially when your air conditioning unit shows signs of a potential problem after winter. Homeowners should know how to protect their unit during the idle months and what to look for when turning it back on during the spring to ensure they are getting the most out of their unit.
These are just a few tips to give you and your air conditioning unit ahead starts in the summer and keep your home cool in the Las Vegas heat.
What can I do for cold maintenance?
Keep the condenser clean
Basic cleaning of your outdoor condenser involves removing the top of the unit and using a garden hose to spray the dust from the inside out. Dust enters the unit from the outside, so it is critical to spray the powder rather than push it further into the coil. You also want to avoid chemicals, which can cause premature oxidation. Even the mildest chemicals must be cleaned properly to prevent damage to the unit.
Professional cleaning for summer maintenance is always recommended to ensure the safety and efficiency of your unit.
Get rid of those covers
Using a cover on your unit may seem like a good way to protect it from the weather during colder months, but covers can cause moisture build-up and premature rust, leading to significant long-term problems.
It is normal for some water leaks from the PVC main drain line during wet weather, but watch out for excessive leaks. Signs of rust at the main drain line outlet can sometimes indicate a problem that requires the attention of an HVAC technician. Also keep in mind that whenever the secondary drain pipe starts to leak water, there is definitely a problem.
You can distinguish the main drain line from the secondary drain line by location. The main drain line is usually out of sight, where it can safely drain the condensation that all units create. The secondary drain line is purposely located in a conspicuous place so that if water leaks, it will not be lost.
Typical locations for the secondary line are above a window or door, in the garage, or even in a hallway in some condos or townhomes. Water only leaks from the second line when there is a problem with your unit, so if you find water there, call for service immediately.
WHAT SHOULD I DO WHEN I TURN IT ON AGAIN?
Check the heat of the unit
Checking the temperature of the air expelled by the outdoor condenser fan while the unit is running can also indicate if the unit is running. If the heat coming from the top of the condenser is warmer than the outside temperature, it means that heat transfer from inside the house is taking place.
Feel the bigger of the two copper lines
Examining the huge copper line coming from the unit is quite possibly the most proficient approach to test your AC subsequent to walking out on in the spring. If the line is what we call a “cold refrigerator” then it is a good indication that the unit should be in working order. But remember, even a cold line doesn’t tell you everything, and regular service with yearly coolant level checks is recommended.
Trim the growth around the unit
Winter foliage that has grown around the unit should be trimmed at least 12 inches from the sides of the equipment. This will help prevent branches or debris around the condenser from blocking airflow to the unit and will prevent it from entering the unit and disrupting functionality.
If you see pet hair or yard debris coating the condenser coils or accumulating inside the unit, the efficiency of the system will be adversely affected. The particular condenser coil and the unit as a whole should be cleaned annually for optimum efficiency.
WHEN SHOULD I CALL THE PROS?
If you notice your unit wobbling, this could indicate problems with a motor shaft that may need to be repaired or replaced. It could also indicate an unbalanced blade, which can be changed without replacing any engine component, saving you time and money. Schedule an inspection with a professional to determine the problem.
Older compressors may make a slight noise during use. This is completely normal. Be that as it may, abundance commotion could mean a free fan sharp edge or a more regrettable issue.
Condenser motors often shut down with a crash and cause a loud screeching noise. Owners should stop the unit and have it checked immediately if they hear unusual noises.
