Your heating and cooling system should keep your home comfortable throughout the year and also boost your indoor air quality. If the system breaks down, immediate HVAC repair is a must to get it up and running again. Knowing when a breakdown is imminent can help you get the service you need before any major issues occur. 

Do You Need HVAC Repairs? Here’s How to Tell

1. Problems With Airflow

Poor airflow can have numerous causes. Minor issues include soiled air filters or blocked vents, which can be easily rectified.

If the problem is more serious, however, diminished refrigerant levels, fan malfunctions, or coil problems may be to blame. Without proper airflow, your unit’s heating and cooling capabilities will be compromised. 

2. Continuous Cycling

Once the HVAC unit reaches the temperature on the thermostat, it will power down until the temperature in the room changes. 

Constant cycling, or a unit that continuously turns on and off, can stem from a wiring issue. It can also result when the refrigerant level is too low. Not only does short cycling affect the comfort of your home, but it also raises utility bills exponentially. 

3. Strange Noises & Smells

All HVAC units make noise when operating. However, new or troublesome sounds usually mean that something is wrong. Additionally, different types of noises indicate different problems.

Rattling can mean a loose or damaged component, while buzzing may point to problems with fan motor operation. When it comes to strange smells, a burning odor often means faulty electrical components, while a musty, damp smell might indicate that mold is growing within the cooling equipment.
