7 of the Most Common Air Conditioner Problems

Published on Apr 3, 2020 in Air Conditioners

As warmer weather approaches, it’s time to start thinking about making the switch from heat to air conditioning. Make sure your unit works ahead of time.

Common air conditioner problems can leave you stuck in the heat on the hottest days of summer if you don’t. Keep reading to learn 7 common AC problems that are anything but cool!

1. Refrigerant Issues

Air conditioners use freon as a refrigerant to absorb the heat and humidity from the room air. As it does, it turns from a high-pressure gas to a low-pressure liquid and then reverts once it cools again. 

As air conditioners age, the metal can erode, leading to a freon leak, so the unit will not cool the air effectively. Uncontrolled leakage of freon can also lead to refrigerant poisoning if not taken care of promptly.

2. Broken Blower

Common air conditioner problems can also come from a broken fan. Your unit uses two of them.

One fan blows air onto the evaporator coil to cool it. The other blows the air onto the outdoor condenser to release the heat outside.

If one fan breaks, you may notice your air conditioner is working but not cooling. Dirt, broken belts, insufficient lubrication, and motor trouble can all lead to poor airflow. Call for professional service before it turns into a larger problem.

3. Duct Leaks

Inside your walls, ducts transport the cold air from your air conditioning unit to the rooms. Rodents or other issues can sometimes put holes in the ducts.

This causes the cooled air to seep into the walls instead of making its way to the rest of the house. While your house feels warmer, you will see higher energy bills, as this causes the unit to work harder in order to reach the temp you set the thermostat to.

4. Faulty Thermostat

Sometimes, thermostat problems can be a simple self-fix. Make sure you properly set the digital settings or correctly calibrate the dial.

Also, check to see that the inside of the thermostat is level, clean, and not in direct sunlight. If you do all this and recalibrate it to no avail, you may need the thermostat replaced.

5. Drainage Clog

Some AC problems happen from clogs and not breaks. The system contains a drain to dispose of the moisture your AC removes from the air.

If the line or drain gets blocked with dirt or debris, the moisture can damage the air conditioning system. Call for HVAC repair quickly, as the moisture can also damage your walls and cause dangerous mold to grow inside of them.

6. Corroded Coils 

Your AC system contains evaporator and condenser coils that can corrode over time. They need HVAC service every few years to keep them working properly.

7. Dead Compressor

The compressor runs the show by pushing energy through the coils and operating the air exchange. Letting other issues go can lead to a broken compressor. Unfortunately, this is the most expensive repair and often calls for a new air conditioner.

Avoid Common Air Conditioner Problems

Stay cool this summer. Avoid common air conditioner problems by changing filters and keeping up on regular maintenance.

The Undeniable Importance of HVAC Preventative Maintenance

Published on Mar 16, 2020 in Air Conditioners

An impressive 15 to 20 years — that’s how long central air conditioners in the US last. Furnaces have the same average service life, while boilers can last up to three decades.

Still, factors like installation, size, and environmental factors can affect this life span. Rains and humidity, for instance, can cause premature corrosion in HVAC components. This can cause early part failure, which can mean expensive repairs or replacements.

Fortunately, homeowners can keep these issues at bay with HVAC preventative maintenance. More than that, routine HVAC tune-ups can help bring down heating and cooling costs.

Keep reading to learn how HVAC maintenance works and what makes them so important.

Maintain an HVAC Unit’s Peak Performance

Unlike many states, Arkansas hasn’t seen drastic changes in its average temperatures. Very hot days and much warmer nights, however, have become less unusual in the state. Moreover, the EPA says that the Natural State will become warmer in the following decades.

At the same time, many parts of the state have had lower-than-normal temperatures. In 2019, for instance, AK had record-breaking extremely cold temperatures.

As a result, homeowners are likely relying more on their HVAC system these days. This increased use also means that their unit accumulates more dust and debris, and at a faster rate.

Dirty filters, clogged coils, and filthy fans can all impede the unit’s performance. Moreover, debris build-up causes airflow restrictions. All these can force the heater and cooler to use more energy than necessary.

One of the goals of preventative HVAC maintenance is to clear such obstructions. Without restrictions, both the heater and the AC can retain their peak performance.

Improved HVAC Efficiency Means Lower Energy Costs

Heating and cooling expenses account for up to 42% of a typical household utility bill. Inefficient air conditioners and ill-maintained heating systems, however, can account for more.

Again, this is due to HVAC units having to use more energy to keep indoor temperatures at the desired level. An increase in the use of the heater or AC also means that their gears and parts lose lubrication more quickly. Without lubrication, these parts can overheat due to higher levels of friction.

Heating and AC preventative maintenance, aside from extensive cleaning, also includes part lubrication. As a result, these once-a-year tune-ups can help reduce energy costs. Moreover, they help prevent early component failure due to overheating.

Early Detection of Failing HVAC Components

Damages like cracks and dents can occur in heat exchangers, lines, pumps, and fans. Air ducts can also develop cracks and holes that can waste up to 30% of conditioned air.

Air conditioners and boilers can also develop water leaks that may lead to water damage. Clogged condensate lines and pipes, busted seals, or broken valves are often to blame.

Routine heating and air conditioning preventive maintenance can help reveal these defects. From there, an HVAC professional can promptly repair or replace the damaged part.

Prevent Early Failure With HVAC Preventative Maintenance

HVAC preventative maintenance helps retain a system’s heating and cooling efficiency. It also ensures that the unit can withstand long-term use. Most of all, regular tune-ups help extend an HVAC system’s service life.
