Thermostats play a vital role in ensuring that your air conditioning system starts and stops properly, so it’s important to have one that works. However, as thermostats age, they can develop technical problems that affect their performance and energy efficiency. To prevent issues, you should replace your thermostat when it reaches the end of its useful life or if you notice any of these common symptoms of an unresponsive thermostat.

If your thermostat is showing a blank screen, it can be a sign of a problem with its power supply. Often, this means that the batteries are dead. In other cases, it could indicate a tripped breaker in your home’s circuit panel that needs to be reset.

It’s difficult to tell if the thermostat’s temperature sensors are malfunctioning without having a professional take a look. These sensors are designed to measure the temperature of your living space, but over time they can get dirty from dust and lint buildup. Cleaning these sensors can help to improve your AC’s energy efficiency and performance.

A faulty thermostat can cause your air conditioner to run constantly, even when the room is already cool enough. This puts unnecessary stress on the compressor and can lead to early failure. A trained professional can determine the cause and perform the necessary repairs to restore your thermostat’s functionality.

The evaporator coil’s primary function is to absorb heat from the air in your home. This process is crucial for your AC’s ability to cool. However, if this coil becomes clogged, it can drastically reduce your AC system’s performance capacity.

Dirty evaporator coils are often the result of dust, dirt, and other debris. The problem is that this can hinder airflow, making it difficult for the coil to absorb heat and make your home comfortable.

If you suspect that your evaporator coil is dirty, be sure to check the unit’s owner manual for detailed instructions on how to access it safely. Once you have accessed the coil, remove any dirt or debris that has accumulated. You can also spray the coil with a cleaning solution that’s safe for your system. When you spray the coil, be sure to have containers on hand to catch any dripping water.

Finally, you can use a tool called a fin comb to straighten any bent aluminum fins on the coil that have been caused by debris or by normal wear and tear. The goal is to get the fins back into a nearly original condition. You can also minimize the amount of dirt that builds up near your coil by cleaning the area around it and keeping it clear of leaves, twigs, grass clippings, and other yard waste.

Keeping up with regular cleaning, inspection, and professional service can help to prevent problems like dirty evaporator coils that lead to more costly repairs down the road. However, it’s also important to do your research when choosing an AC company to ensure that they are licensed and insured. You can do this by checking the Better Business Bureau website for reviews and ratings.

An air conditioner that is low on refrigerant will not cool your home and it can also run your energy bills up, as well. The reason that this happens is that the AC system runs longer and at higher speeds when it has to compensate for the lack of refrigerant, which can cause it to overheat.

The refrigerant is the “secret sauce” that allows your air conditioner to absorb heat and transfer it to outside air. However, if you have a leak somewhere in the copper refrigerant line, it won’t be able to do this. There are many places where this can happen, but one of the most common is at a “U” bend or a weld. It can also occur if the tubes are vibrating too much, which can put stress on the joints and welds that can cause them to leak.

Once a technician finds the source of the leak, they can fix it. They have a few different methods for this, but the most reliable is to drain the system and then pressurize it with nitrogen. When they do this, it pushes out gas through the leak, which is then easily visible with soapy water. The technician can also use a method that involves adding fluorescent dye to the system and then scanning the pipes with a black light to see the spots where the dye is leaking out.

Leaks should always be repaired by a professional because the process is quite complicated and it could damage your AC unit, especially if it is an older system. In addition, attempting to repair a leak can void the warranty on new units.

Air filters are one of those easy, out-of-sight, out-of-mind home maintenance items that can single-handedly send your HVAC system to an early grave if you neglect them. Most people assume that the reason we tell them to change their filter is because a dirty filter spreads allergens throughout the house, but there are many other reasons you should clean yours once a month (or replace it).

When an air filter gets clogged with dust, the velocity of air flowing through the ductwork slows. This forces your AC to run longer than usual just to reach the thermostat’s set temperature, which means it consumes more energy.

The airflow slowing down due to a clogged air filter causes dust and other particles to settle on the evaporator coil, where they can freeze up if there is enough of it. This can cause the evaporator coil to fail, requiring a major and expensive replacement part.

Changing your air filter is an inexpensive way to keep your AC running properly and protect the integrity of your evaporator coil. Make sure you have the right size air filter in place, and remember to change it regularly so you can avoid expensive repairs. If you want to be proactive about your home’s maintenance, consider hiring a professional to inspect your AC for potential issues and repairs. information, visit us online or give us a call today!

Regardless of how sturdy they are, the fan blades in your AC unit are not indestructible. Over time, they may become bent or loose, which can cause them to strike other components of the system when spinning, causing damage and noise. This is a problem that should be fixed as soon as you notice it so the damage does not spread or lead to further issues.

Sometimes, the fan itself may simply be overheating, and it might cause a power surge that triggers your circuit breaker to shut down. If this happens, the easiest fix is to flip the breaker back on to restore power and get your AC running again. However, you should have an HVAC technician come in to inspect and repair any issues that caused the tripped breaker to be flipped in the first place.

If your fan is not turning on at all, even when you kick-start it with the manual stick, it likely has a dead motor. This is more common in systems that are poorly maintained or operate in areas where a lot of dirt and debris is blown around the fan. If this is the case, you will need to have a technician assess your system and replace the fan.

Whether or not you choose to have your broken fan repaired depends on the cost of repairs compared to the value of a new AC system, your skill level with DIY projects, and your comfort needs. If you do decide to replace your fan, be sure to dispose of the old one responsibly. This involves assessing the warranty, safely unplugging and disassembling the fan, and sorting the components for recycling or disposal according to guidelines provided by your local recycling center.
