Main Causes of AC Failure and How to Prevent Them

The air conditioner is generally considered to be among the most important appliances in a residential property. Like any appliance, it’s prone to suffering from issues due to all of the parts and mechanisms that are included. As a homeowner, it’s essential to be aware of the main causes of AC failure and how to avoid them.

1. Low Refrigerant

The refrigerant in the AC system is used to remove the heat from the air as the interior setting is cooled. Leaks can often develop in the refrigerant lines, which means the air won’t get cool. This problem can be avoided by hiring a professional from a company like Gilmore Heating Air & Plumbing⁣ to perform a tune-up every six to 12 months. This will allow you to monitor the condition of the refrigerant lines.

2. Thermostat Issues

Your thermostat may eventually begin to malfunction, especially if it’s an old dial-type that’s not calibrated correctly. Your AC system may not be getting the right instructions from the main control system. The problem can be avoided by replacing an outdated thermostat early on or checking the manual to ensure the settings are accurate.

3. Issues With the Fan

A faulty motor or a lack of lubrication can prevent your AC fans from operating. To address the issue, hire a technician to lubricate the parts every six months with tune-ups that are scheduled. This will keep the fan operating properly.

4. Dirty Condenser Coils

Condenser coils are prone to getting dirty and accumulating grime. Once the dirt becomes too thick, the AC will break down or turn off frequently. Make it a point to clean the coils to improve the operation of the parts.

Is It Time to Upgrade to a New Air Conditioner?

When Do You Upgrade Your Air Conditioner?

The air conditioner is one of the most important appliances in a building. It determines how comfortable the interior setting is during the warmer months of the year. Although air conditioners are built to last for a long time, they eventually reach the end of their lifespan. Over time, issues can begin to occur, and the product may not operate well. Here are a few of the top signs that it’s time to upgrade to a new air conditioner.

1. Lack of Cool Air

One of the most obvious signs that your air conditioner is no longer operating is if cool air isn’t blowing out of the vents in the building. You may notice that the home isn’t getting cool or that certain rooms of the home are staying warm. Older AC units that need to be replaced are also prone to breaking down frequently or need repairs on a consistent basis. In some cases, it may be more cost-effective to replace the appliance rather than continuing to fix it.

2. The AC Is Old

Checking the age of your air conditioner is one of the main ways to determine if it needs to be replaced. Most air conditioners last an average of 10 years before they begin to have issues. Air conditioners undergo regular maintenance can last up to 15 years. The unit may also use Freon, which is being phased out by the government because it’s not an energy-efficient gas.

3. You’re Dealing With Expensive Repairs

Although air conditioner repairs commonly occur from time to time, it may not be worth fixing the appliance if the repairs are too expensive. In some cases, the repairs may cost more than replacing the unit, which means that it’s time to upgrade to a newer model.

Diagnosing Residential Air Conditioner Problems

Your residential air conditioning system needs periodic attention. Even so, problems can happen. Before calling for help, it’s possible to save time and money by doing some AC troubleshooting of your own.

AC Doesn’t Run

  • If your system doesn’t turn on at all, make sure it’s getting power. Check the fuse or circuit breaker. If your system has a secondary breaker near the outside unit, verify that it’s on.

Air Conditioner Turns On and Off Too Often or Not Often Enough

  • Your system cycles based on a sensor you know as the thermostat. Verify that it is set in the ‘cooling’ position. If it is located in a small, isolated room, other rooms may not cool properly. Consider moving it to a larger, more centrally located room.
  • If your system starts and stops frequently, it may be too big, or a register could be blowing on a thermostat.
  • If your system seldom cycles off, you could have low refrigerant levels or faulty relay switches.
  • Dirty filters and intakes can prevent your system from pulling in enough air to properly cool your home. Check your air filters and exchange them regularly to keep your home comfortable. Alternatively, consider upgrading to a media filter, which only requires semiannual attention.

Water Accumulating Under the AC

  • Pooling water in your AC unit’s drip pan could mean a broken condensation pump or a blocked drain line (if it’s the latter, you can try clearing the line with bleach). Either way, that water means it’s time to schedule service. You should consider installing a safety shutoff switch that will turn the unit off if drain lines back up.

AC Runs, But Doesn’t Blow Cool Air

  • If your system blows warm air, check that the outside unit is running, and that its airflow isn’t blocked by leaves or debris.
  • If the fan on the outside unit isn’t turning, turn the thermostat fan switch to the ‘off’ position. If the inside fan continues running, turn off your system breaker and schedule service. Your problem could be insufficient refrigerant. Your air conditioner is a closed system. If it’s low on refrigerant, you have a leak, which commonly occurs at valves or in the coil. Finding a leak is work for a professional.
  • If your blower motor is running but not cooling, your system is probably frozen, and needs professional attention.
