The Most Common HVAC Repairs and How to Prevent Them

hvac technician

Malfunctioning HVAC systems can cause extreme discomfort and cost you big bucks to fix them. You can prevent most issues, however, with proper maintenance on your heating and cooling systems. At All 1 Mechanical, we perform annual maintenance which will not only keep your system running more efficiently, but also prevent most unexpected repairs. 

Below are the most common HVAC repairs and how you can prevent them from catching you off guard. 

Most Common HVAC Repairs 

These common issues might seem like something you can leave for a while before fixing them, but if you don’t get them taken care of promptly, they can become more serious issues that cost you more time and money. 

Air Filter Issues

An air filter in an HVAC unit controls the airflow and air resistance. It removes dust, dirt, and other debris from the air resulting in better air quality. Over time, the filter becomes dirty and will eventually clog. This causes unnecessary wear and tear, which decreases the system’s efficiency. Clogged filters are no joke and can lead to more hassle later.

Water Leaks 

Condensation is produced with HVAC systems, no matter what you do. Furnaces can leak water if the drain lines are cracked or clogged. Ensuring the drain lines are healthy is key to preventing water leaks and further issues. 

Blown Fuses or Tripped Breakers 

Blown fuses and tripped breakers are caused by airflow blockage. A clogged air filter is the most common thing that causes blocked airflow. If you experience frequently blown fuses and tripped breakers, it will require professional help to resolve the issue. 

Blower Motor Won’t Shut Off

A continuously running motor is likely a sign that the thermostat is set in the FAN position. If this is not the case, the fan relay connected to the blower might be stuck. Call a professional if you have tried to switch the thermostat off of the fan, but it is still blowing continuously. 

Thermostat Problems 

Thermostat issues could be an easy fix. If you have an older thermostat, it might just need a recalibration. The thermostat could be causing your HVAC unit to work harder because it is incorrectly calibrated. 

Dirty Condenser or Evaporator Coils 

Condenser coils are on the outside part of the unit. These coils get dirty because they are exposed to a lot of dirt, dust, and debris. In large cities, dirty condenser coils are a common issue. Once they become dirty, they work less effectively, which causes the unit to work harder and, eventually, break down. 

Evaporator coils are inside the unit. They are filled with refrigerant because they help cool the unit by absorbing external heat. If the evaporator gets too cold, it will freeze. When this happens, your unit can not supply cool air. Instead, you will feel warm air when it should be cool, or no air at all. 

Mechanical Wear and Tear 

HVAC units might be more complicated internally than you think. Many pieces inside the unit work together to produce quality heat and air services when you need them. Common parts that need replacing due to wear and tear are belts and bolts. If you don’t perform scheduled maintenance, these belts and bolts will eventually break and cause more issues in the future.
