Signs You Need an HVAC Repair Service


If you’re experiencing strange sounds from your HVAC system, it’s time to check it out. There’s a good chance one of the components needs cleaning, adjusting, or even replacement. Identifying the problem early can save you a lot of money. Here are some of the signs you should look for.

Warm Air Coming From Your Vents

If you notice warm air coming out of your vents, it’s a sign that your HVAC system needs to be repaired. The cause of this problem can range from a clogged air filter to a problem with the motor. If you notice warm air coming from your vents, call an HVAC repair service like GoGreen Heating and Air Conditioning to diagnose and fix the problem.

A thermostat set lower than the indoor temperature can also cause this problem. The most common cause of this problem is a restriction in airflow. A professional HVAC repair service can inspect the ductwork and determine the source of the problem.

Unusual Sounds

A strange sound from your HVAC system is a warning sign that you must contact an AC Repair service. It could be an abnormal click, squeaking, rattling, or banging. These sounds usually occur when a component fails, and early repair will save you money and trouble.

Repeated clicks may indicate that the thermostat or compressor is malfunctioning. An AC repair service technician will look at these parts. If the noise comes from the outside unit, debris may be caught in the fan or panel. Faulty electrical signals can also cause it. You should call a repair service if you notice small sparks near the noise.

If the noise comes from the AC compressor, this could indicate an AC compressor failure or high refrigerant pressure. Another warning sign is a buzzing or booming noise from the air duct system.

Strange Odors

Strange odors in the HVAC system are one of the most common indications of an underlying issue. These smells can result from some issues, including improper ventilation, clogged filters, or problems with the condensing unit. If you notice any of these odors, you should immediately contact a qualified HVAC repair technician.

Odors that are electrical or oily can also be a sign of a serious problem. Sometimes, the smell may be caused by a loose fitting on the tank. However, it may also be due to a clogged burner. Either way, call a professional immediately to avoid any further fire risk.

Strange odors in the HVAC system may also mean the unit is leaking Freon. This is a dangerous gas that can be dangerous if it leaks into the home. Freon can damage your lungs and cause a putrid smell. A professional HVAC repair technician can diagnose the problem and make an accurate diagnosis.

Short-Cycled System

There are several signs your HVAC system is experiencing short-cycling, and it’s important to seek a repair service immediately. This problem occurs when the unit repeatedly turns on and off without completing its cooling cycle. This condition degrades the health of the HVAC system and costs you money in the long run.

Some common causes of short cycling include dirty air filters, clogged air filters, and iced coils. These issues can restrict air flow and result in overheating. In some cases, you can fix the problem yourself, but many times, you’ll need a professional to repair your AC.

Short cycling is a sign of a more serious problem. Luckily, an HVAC repair service is equipped with the proper tools to diagnose and fix short cycling. These experts can also determine if a system is oversized and need replacement or if there’s a leak in the refrigerant.

Mold and Mildew Growth

When you notice mold or mildew growth on your HVAC system, you may need to call an HVAC repair company to help you clean it:

  1. You should turn off the HVAC system to prevent the spreading of mold-causing fumes.
  2. You should remove all the mold-causing materials from the HVAC vents. Use a garbage bag with a 6-millimeter-thick layer to collect them.
  3. Use a spray bottle to apply the cleaning solution to the affected areas.
  4. Use a disposable towel to wipe off any excess solution.

If you’ve noticed mold and mildew growing on your HVAC system, you need to call an HVAC repair company immediately. If the growth is severe, you may need to hire a mold remediation company to help you. In addition, you should clean your system regularly to prevent the recurrence of the mold.
