Which HVAC Problems Are the Most Common?

Heating, ventilation, and air conditioning (HVAC) systems are essential components of any home or commercial building. The best part is we hardly think about them when they're working correctly. However, when HVAC systems break down, we can no longer provide our employees or family with safe, comfortable air, and the repairs are always a headache.

Numerous problems can occur with your HVAC system, but some are more common than others. By developing a deeper understanding of the most common issues, you can be better prepared to deal with them when they arise. Most importantly, you’ll know when it's time to contact a professional HVAC company for help.

Some measures you can take by yourself include: checking the furnace filter, making sure the thermostat is set to the correct mode, checking batteries in the thermostat, and checking the wiring for any damage. 

Common HVAC Problems 

Let’s explore some of the most common problems homeowners face that require HVAC maintenance.

No Heat

One of the most common problems with an HVAC system is a lack of heat coming out of the vents. Heating issues could result from problems with the furnace unit, the thermostat, or even the wiring. When this happens, it's important to contact a residential or commercial heating repair service to troubleshoot the problem as quickly as possible. Fixing your heating problems as soon as possible prevents additional failures or mounting costs.

There are measures you can take by yourself, such as checking the furnace filter, making sure the thermostat is set to the correct mode, and checking the wiring for any damage. If you still aren’t getting warm air, contact HVAC technicians to avoid further damages and get your heat back up and running. 

No Cool Air 

Problems with central air systems will reduce the cool air coming from your vents. Room temperature or warm air coming from your home or commercial air conditioner could be due to a clogged filter, a dirty evaporator coil, a refrigerant leak, or a problem with the fan. If you notice that your unit isn't providing any cool air, you should connect with an HVAC technician right away.

Clogged filters can be cleaned and replaced, but if the coil is dirty or the fan is damaged, you need to call an air conditioner repair professional. Addressing A/C issues promptly can save you and your family from suffering through the summer heat with uneven room temperatures due to air conditioning problems. You’ll also avoid costly repair and energy bills in the future. 

High Utility Bills 

One of the most frustrating issues with an HVAC system is increasing your utility bills. This could be caused by many issues, such as a dirty filter, an inefficient system, or even a broken thermostat. 

If you're noticing that your energy bills have been increasing without a significant change in habits, take a closer look at your home or commercial HVAC system with a trusted technician. A trained professional can find the source of the problem and take steps to rectify your high use. A simple cleaning or adjustment can often help get your system running more efficiently and save you some money in the process. 

Odd or Disruptive Noises

Sometimes, HVAC systems make strange noises. While this isn’t always indicative of an issue, they are often a sign of something wrong. Noises can indicate a problem with the fan, the compressor, the heating element, or even your ductwork. 

If you're hearing strange noises coming from your HVAC system, take note and contact a technician for HVAC repairs. Depending on the source, odd noises can help you predict when a particular part of your system is about to fail. It's best to address the problem before it requires more costly repairs or leaves you without comfortable air. 

Tripped Breakers 

If your HVAC system is constantly tripping breakers, it's a clear sign something is wrong. HVAC wiring or compressor problems can cause your system to overload. When this happens, it’s likely that you have an electrical issue. Delaying repairs could result in a total system breakdown, so it's important to address this problem as soon as possible. 

Frozen Components

Frozen HVAC components are another common problem you may experience in winter or summer months. In the winter, your heat pump coils may freeze from a lack of proper airflow. The resulting condensation can cause frost and temperature fluctuations that can damage your entire system.

In the summer, your AC may freeze due to issues with the coils, the compressor, the fan, or a dirty filter. When this happens, the system will not provide any cool air, and it could potentially damage the entire unit. If you're experiencing problems with frozen components, it's important to act right away by calling an experienced HVAC professional. 

Water Leaks 

Another common problem experienced by HVAC systems is unexpected water leaks. Water may gather around your unit due to a leaky coil, a clogged drain line, or a problem with the condensation pump. If you're noticing water leaks around your HVAC unit, you should take action before your home experiences severe water damage and system failure. 

System Breakdown

A total system breakdown can be caused by a number of things, such as a clogged filter, a dirty coil, or even wiring problems. When this happens, call a professional HVAC company to help get your system up and running again. Depending on the severity of the problem, it may be more cost-effective to replace the entire unit rather than repair it. Your technician will help you arrive at the best solution to protect your home or business and save you money in the long run.
