How Often Should I Service My Air Conditioner?

Air conditioner is one of the essential modern time amenities. However, it is also one of the things which don’t cross our minds until it’s already a scorching summer and we need protection from the heat. Before you need to call for an air conditioning service San Diego to service your broken or malfunctioning unit, ask yourself – how often should I service my air conditioner?

Depending on how old your AC unit is and whether there are any problems, there are suggested periods of time in which it should be serviced. This is required in order to avoid any larger subsequent issues and for it to be fully operational during the summer season.

The importance of an air conditioner service

Having your AC unit checked regularly is beneficial in several ways. First and foremost, it enables the proper functioning of the system during peak summer temperatures. By having it checked according to a schedule, you will catch wind of any potential problem before it becomes serious.

As the AC system ages, it loses the original efficiency, which means it requires additional energy to function properly. By regularly servicing it, smaller issues will be served in time to preserve the efficiency and result in potentially smaller electricity bills.

The frequency at which an air conditioner unit should be serviced

“How often should I service my air conditioner?” – this is question we’re asked on a regular basis. There are different parts of an AC system which require servicing at different times, but experts recommend a minimum of a yearly check-up. Such a schedule is necessary for an optimum performance. The aspects which need to be taken care of are filters, coils, coil fins and compressors.


Even after regular yearly maintenance, there are several things you can do yourself to help the AC system function optimally. To prevent a drop in the energy efficiency, clean the air filters every two weeks. There are different types of filters, and the amount of gathered clogs depends on the usage. Some of them can be cleaned and reused and others need to be changed with new ones. If not cleaned every two weeks, at least once a month is recommended.


The system consists of two coils which can overheat if excessive dirt accumulates over time. They are the evaporator coil and the condenser coil and they need to be serviced once a year. If this isn’t done, it can bring down the overall efficiency of the AC system.

Coil fins

Coils are covered with aluminum fins, which are very fragile and can break. In order to prevent the coil fins from bending and blocking the airflow, regular service can make them stay in their original shape and out of the way.


When a compressor overheats, it can have dangerous consequences. This is another issue which can be prevented with regular maintenance.

What is Refrigerant and How Do You Know if You Have a Leak?

how to check the refrigerant level of an AC What is air conditioner refrigerant?

Want to know how to check the refrigerant level of an AC? We have the answers. Refrigerant is the substance that is contained in the copper coils of an AC unit. It switches between liquid and gaseous states and in the process cools and dehumidifies the air. For decades, the most common refrigerant was R-22. However, this refrigerant has ozone-depleting properties and is therefore extremely harmful if it leaks out of the AC unit. Right now, R-22 is being phased out and gradually replaced with ozone-friendly alternatives, such as R-410A, which doesn’t contain chlorine.

When to recharge AC refrigerant?

Your AC is a closed, sealed system that doesn’t use up the refrigerant. You absolutely don’t have to top it off with refrigerant just because some time has passed since you bought your system.

At the time the equipment was originally installed, it should have been charged with the correct amount of refrigerant. However, off-season installation in cold weather may be a factor in achieving correct values. Action Air offers complimentary checkup and adjustment if necessary for your system after it has had time to perform.

Once the system has been adequately charged, maintenance is recommended to monitor its performance.

If more than one pound of refrigerant is required to meet the correct level, most likely there is a leak. Instead of dumping more costly pounds of refrigerant into the system, put your money towards finding the source of the leak.

How to check AC refrigerant levels?

If it takes significantly longer to cool your home and you suspect your air conditioner is low on refrigerant, then the first thing to do is go to your outdoor condenser unit. Find two copper lines that go into the unit and put your hand on the larger, probably insulated, line. If the line is sweating and if it is cool to the touch, chances are your AC has enough refrigerant.

Next is to check the tubing of your unit. Inspect the lines for kinks, holes and hissing or gurgling sounds.

Of course, the easiest and most reliable thing to do is to have a professional inspect the unit for leaks. There have been many instances when homeowners thought that they have a leaky refrigerant problem, when in fact their outdoor unit was just dirty, or their ducts were blocked, etc.

What should you do if it is leaking?

Your AC refrigerant has to recharged, but it’s also essential to locate the leak(s) and solve the problem. It’s highly unlikely that you can do this on your own, without a professional. Remember, you cannot solve the problem by simply adding a pound or two of refrigerant. If an AC technician tries to sell you the recharge without tackling the leak source, that’s a clear indicator of un-professionalism.

How to prevent refrigerant leaks?

Keep pets away from the outdoor unit. You can put up a fence around to prevent your dogs or cats from urinating on the unit. Dog’s urine is highly acidic, which can damage the coils. The fence should give the unit at least 2ft space all around, so the unit can function without problem.

Adjust sprinklers so they don’t directly hit the unit. This will cause premature corrosion of the coils.

Why HVAC Maintenance Is Critical to Your Home & Energy Bills

Did you know that 90% of all HVAC system malfunctions or breakdowns are caused by a lack of maintenance?

The best thing you can do for your heating and cooling system is to have a reliable NATE Certified technician perform regular service on it. Unmaintained gas furnaces, especially older models, are a safety hazard and could be potentially put you, your family, and home at great risk.
An Action Air NATE-Certified technician discovered this entire house was at severe risk for fire and carbon dioxide poisoning after receiving a routine repair call about a furnace not producing heat.
This can potentially happen to you. If you notice anything out of the ordinator about your HVAC system, it is important to immediately call an HVAC contractor, like Action Air.

Here are a few signs your furnace could be putting you and your home at risk:

  • Smell of burning coming from HVAC after heat is turned on
  • Strong smell of fuel
  • Carbon dioxide monitor goes off
  • No heat is being produced
  • Utility bills increase
  • Your HVAC is making loud or unusual noises (rattling, buzzing, banging)

Having your HVAC system regularly serviced (2 times per year) is the best way to ensure your furnace is safe and reliable. Additionally, regular maintenance will improve your home’s indoor air quality, enable your system to operate at optimal performance, reduce energy costs, and mitigate expensive repairs.
