One of the biggest reasons you need to get your HVAC systems repaired as quickly as possible when something goes wrong is that minor problems often become larger ones. In other cases, a small problem could be a symptom of something much worse happening that isn’t readily apparent. Regardless, the sooner you get your HVAC system repairs done, the sooner you’ll be able to rest easy knowing that your system isn’t going to fail on you or become damaged beyond repair. With this in mind, let’s review the ten most common repairs for your home HVAC system.
Dirty Filters
Dirty filters may not seem like a big deal, but they can lead to big trouble if ignored. This is because a dirty filter forces your unit to work harder to do its job. As you can imagine, this puts a significant strain on the fan and, in some cases, can even cause the unit to shut down entirely if it overheats from the stress. On top of this, a dirty filter diminishes the air quality in your home which can cause problems for those with allergies or asthma. Since changing your filters can be a pain, having a professional HVAC repair company do it is an excellent option.
Dirty Evaporator Coils and Condenser
Speaking of things becoming dirty, another common residential HVAC repair issue is having a dirty condenser and/or dirty evaporator coils in your unit. This can cause it to have a much harder time when it comes to cooling your home. The most common way to deal with this is to shut off the power and use a hose to clean the unit. However, this is problematic for two reasons.
Firstly, you’ll only be cleaning areas the water can reach which likely won’t be enough to clean some of the deeper parts of the unit. Secondly, using water to clean a machine that runs on electricity can be dangerous if done improperly. In most cases, letting professionals handle dirty evaporator coils and condensers is the easiest and safest way to deal with this problem.
The Blower Fan Doesn’t Work or Underperforms
 If your blower fan is damaged or broken, your HVAC unit can’t function because there will be no airflow. This is one of the most common home HVAC repairs and can be caused by various things. Such as the fan becoming jammed or damaged or having the axle that the fan rotates on becoming bent somehow. In any case, a fan that isn’t working or is underperforming should be dealt with as soon as possible.
The Blower Fan Runs Continuously
The opposite of the previous problem is when your blower fan won’t turn off. Sometimes, this means not realizing that the fan function is turned on and set to run even when the HVAC unit isn’t heating or cooling. However, the fan can also get stuck turned on for other reasons such as a malfunctioning safety system or the fan relay being stuck. If this is the case, this isn’t an issue that most homeowners can fix on their own so professional help will be needed.
Thermostat Replacement
A lot can go wrong with the thermostat on an HVAC unit, and sometimes fixing the issue is as simple as resetting the thermostat or replacing the batteries if you’re using a programmable unit. However, in other cases, there may be no identifiable cause for your thermostat’s problems, and HVAC system repairs will be necessary.
As you can probably guess, having a thermostat that’s not working correctly can lead to various problems. Such as the heat not turning off, the air conditioning not turning off, or one or both not turning on when they’re supposed to. In some cases, the temperature reading may even be affected as well.
Regardless of the problem, thermostat issues should be fixed as soon as possible. If you’re having issues with your thermostat or would like a maintenance visit to keep everything running smoothly, call (702) 825-3122 to speak with a friendly Summit AC and Heating representative today!
Clogged Drain Lines
When the condensation drain line in your HVAC unit becomes clogged, it can lead to severe problems. Most notably, the drain pan can fill up, overflow, and cause water damage. With HVAC units being electrical equipment, this can also be very dangerous.
Another problem caused by clogged drain lines is the material clogging them can be harmful. This is particularly true if certain types of algae or mold get into them and begin spreading throughout your home. Calling residential HVAC repair services as soon as possible if you have a clogged drain line is always a good idea.
Defrost Control Problems
Another common home HVAC repair issue is frost build-up in your unit. This can happen when the defrost control isn’t working as it should. Frost in the unit can cause a variety of problems, such as damaging your fan and negatively affecting your unit’s longevity. Since defrosting control problems can result from several issues, it’s a good idea to have a professional HVAC repair company look at your unit to figure out what’s going wrong.
Refrigerant Leak/Refill
The refrigerant system in your HVAC unit isn’t something you want to mess around with on your own. If you have a leak or if it is damaged in some way, call for HVAC repair as soon as possible. As you probably know, mishandling the refrigerant system can lead to a severe accident or injury if something goes wrong. A professional can diagnose the problem and recommend the correct action, whether repairing a leak, refilling the system, or replacing it altogether. This is one issue that definitely isn’t worth the risk of trying to fix yourself.
Weird or Disruptive Noises
While this isn’t typically a cause for HVAC repair in and of itself, unusual noises can signify something wrong. Not to mention, having your HVAC unit make weird noises can be disruptive. Depending on the loudness, they can even make it difficult to sleep or concentrate. In any case, if your HVAC unit is making noises, it shouldn’t be, something is wrong, and if nothing is done about it, things are only going to get worse.
Circuit Breaker and Fuse Replacement
There can be many causes for electrical problems in your HVAC unit, but having a fuse or the circuit breaker go bad can immediately disable your unit. The good news is that replacing a fuse or circuit breaker isn’t that difficult in most cases, and can have your unit working again in no time. The challenging part is figuring out the issue since it may not be readily apparent that it is a fuse and/or circuit breaker problem.
Maintenance and Repair are a Call Away
A lot can go wrong with your HVAC unit if you don’t have it maintained regularly. This can leave you uncomfortably hot in the summer or icy cold in the winter.
