Homeowners dread malfunctioning AC units in the midst of summer for obvious reasons. No one loves sweating under the fiery sun with the cooling systems out of order. This explains why HVAC experts recommend scheduling the AC repair just before the hot months kick in. A spring or pre-summer inspection can bail you out of trouble in most cases.
AC repairs turn out to be difficult during summer for several reasons. The experts at established HVAC companies like Direct Air Conditioning recommend tuning up your system before you reach peak summer.
Let’s check out what might prevent you from seeking swift AC repair services during the summer.
Why do homeowners face delays in AC repair during summer?
In most homes or commercial buildings, ACs work overtime during the summers. While everyone loves beating the heat, very few owners consider taking proper care of these sophisticated systems. As a result, the systems frequently break down under pressure. Some of the common glitches that ACs face during the summer months include:
- Frozen coils in the capacitor
- Blocked drains
- Problems in the fan
- Clogged condenser coils
- Refrigerant leaks
- Thermostat problems
Naturally, households reach out to reputed HVAC experts to get these systems quickly fixed. However, during the peak of summer, the certified technicians remain overloaded with pending repairs. This is one of the reasons for which you can face delays in getting your AC fixed.
- High demand for HVAC technicians
To prevent such delays, it would be wise to schedule routine maintenance or tune-up with a professional HVAC service provider just before the summer months. This way, your system would be perfectly operational during summer. Unless anything critical turns up, you need not reach out to the experts in the next three to four months.
- Unavailability of parts
Another factor attributing to delays in AC repair during the summer is the unavailability of spare parts. The cooling units undergo breakdowns in large numbers due to excessive pressure or the lack of proper maintenance. Due to a seasonable spike in demand for branded spare parts, you might have to wait till they are available. Naturally, you would repent for skipping the routine maintenance of your AC.
- High repair charges
Naturally, with a limited number of certified HVAC technicians available and a high number of complaints, the charges for getting your AC fixed would be higher than usual. This might prompt you to postpone the repair by a few weeks until the charges come down.
Why do ACs stop working during summer?
- Poor maintenance
Just like any other machine like your car, HVAC systems need routine maintenance. These sophisticated appliances have lots of moving parts. On consistent use, these components get exposed to dirt and undergo electrical surges or temperature fluctuations. Harsh weather conditions also take a toll on the functional competence of these machines. Then you need to factor in moisture buildups, grime, and oily matters that affect the parts. Over consistent use, these components start failing, and you encounter glitches in your AC.
Overlooking routine maintenance happens to be the prime reason for premature AC failure during the summer months. Only when the AC malfunctions and leaves you reeling under the sweltering heat do you think of calling the technicians. The lack of timely professional handling leads to extensive repair expenses. Sometimes, you need to get a new system installed altogether.
To maintain optimal efficiency of your AC, make sure to follow up on the routine maintenance schedule. Skipping the maintenance can also void your warranty.
- Problems in fan
With excessive use during summer, the fans in your AC fail to bear the pressure. Most units come with two fans responsible for circulating air in these systems. The first fan blows air from the interiors over the evaporator coil. The other one does away with the warm air. It blows the air over the condenser coils.
When these fans malfunction or eventually fail, the AC gets below-par airflow. Ultimately, the compressor fails, and you end up shelling out a huge amount for repairing the system.
- Frozen evaporator coils
Inevitable glitches in your AC can lead to ice building, even during summer months. If this happens, you will find your AC blowing warm air. The evaporator coil might freeze under certain conditions.
- Firstly, if you have clogged air filters in your AC, it might freeze the evaporator coil. Since there would be no air movement in a blocked coil, the system fails to transfer heat. As a result, the refrigerant present in the coil would be excessively cold. This creates moisture, ultimately causing the evaporator coil to freeze.
- If the air registers are closed, it might block the airflow. The AC should receive adequate air over the evaporator coils to ensure a steady heat supply is absorbed. The condensation accumulating on the coil tends to freeze due to the absence of absorbable heat. So, take care of closed vents and ducts at your home.
- Frozen evaporator coils also stem from low refrigerant levels. When this happens, the AC absorbs less heat. A leak can also cause low refrigerant levels in the AC. Resultantly, the cold air tends to pass over the AC’s coils. Eventually, the evaporator coils would freeze, messing up the operation of your AC.
- In case the thermostat in your AC is faulty, the temperature might fall considerably. Also, setting the thermostat too low can cause the evaporator coil to freeze. Regardless of the root cause, you would witness a dip in the performance of your HVAC system.
Well, now you know why it takes more time for technicians to repair ACs in summer. Also, we have explained the prime aspects that can lead to a malfunctioning AC during the hot months. Professional maintenance and routine tune-ups can help prevent untimely failure in your system.
Reach out to a reputed HVAC contractor like Direct Air Conditioning for professional AC servicing and repairs in the summer. The experts will recommend best practices to prolong the lifeline of your AC.
