5 Warning Signs Your System Needs Professional HVAC Repair


Letting a professional install an efficient heating, ventilation, and air conditioning (HVAC) system is one of your most significant investments. It keeps your home comfortable because it cools your home in the summer and keeps it warm during the winter. These systems can also help improve air quality and ensure better energy efficiency. 

However, being a responsible homeowner goes beyond switching off the systems when you’re not using them. You must also know when to schedule professional HVAC repairs. This step will help you keep your cooling and heating units’ best condition and avoid premature replacements. 

If you want to keep a more comfortable and energy-efficient home, this article will enumerate five warning signs your system needs professional HVAC repair. 

1. Foul Smells 

We’re blessed to have noses to help us detect various odors. Recent research even suggests that we have approximately 400 different scent receptors in our noses, allowing us to identify up to a trillion varying scents. If you can easily differentiate freshly-brewed or burnt coffee from the aroma, you should also know what smells could indicate you need a professional HVAC repair. 

A musty or burning odor from your home’s vents could indicate mold or mildew growth in the ducts. For this reason, you should immediately let a licensed HVAC technician inspect the system and perform a deep air duct cleaning. Moreover, watch out for an electrical smell because it could signal a short circuit.

2. Unusual Noises 

Just because you hear noises doesn’t mean you have a haunted house. Those strange sounds sometimes indicate something’s wrong with your heating and cooling units.

If you hear odd noises like squeals, squeaks, or grinding, your system probably needs an urgent HVAC repair. While it may work correctly, these strange sounds indicate that you must address an issue, such as a component needing cleaning, tune-up, or a replacement. You can save money on costly fix-ups by immediately letting a professional service your system. 

3. Airflow Issues 

Poor indoor air quality can negatively affect the occupants’ health, safety, and comfort. 

Your HVAC can have airflow issues if your home experiences hot and cold spots, doors slamming by themselves, strange whistling noises, or drafty areas. You should never ignore these issues because the strain on your system can cause compressor failure and force you to buy a new cooling unit. For this reason, you should schedule a professional HVAC repair to diagnose and fix the issue.

4. Your HVAC System Isn’t Working

One of the apparent signs you need urgent HVAC repair is when your system won’t switch on. This problem can be highly frustrating for any homeowner, especially during the summer and cold seasons. You should also know that a malfunctioning HVAC system can result from issues like an electrical system shortage or a piping leak.

Regardless of the problem, you should let a professional address it to restore a comfortable temperature.

5. It Switches on and off by Itself 

Your HVAC system keeps your home comfortable by undergoing cooling and heating cycles, regardless of outside weather. Once it finishes this, it will turn off until the process begins again. However, your HVAC is likely short cycling if it switches and off quickly. 

Why Your HVAC Switches on and off Alone

Your air conditioner could suffer from an irregular cycle because of low refrigerant levels, an iced or dirty evaporator coil, or a dirty air filter. While changing the air filter can be a quick fix, you should schedule a professional HVAC repair if that doesn’t work.
