5 Signs It’s Time To Call An HVAC Technician

What Does HVAC Stand For?

HVAC stands for heating, ventilation, and air conditioning. It refers to the systems that regulate and move heated and cooled air throughout residential and commercial buildings. Although there are many choices for HVAC systems, they all work similarly, taking in the fresh air and using a mechanical ventilation system to heat or cool it to the desired temperature. HVAC units also can control humidity levels and improve air quality through air cleaners that capture bacteria, spores, and virus-sized particles.

HVAC Tools

HVAC service or new air conditioning or heating system installation for residential and commercial clients necessitates a qualified professional with access to the necessary HVAC tools and equipment. All great service techs should have a wide range of products in their tool bag to tackle any problem in an HVAC system safely and effectively. This list will cover essential tools that HVAC industry technicians need.

  • Screwdriver
  • Pliers
  • Gauges
  • Extension Cords
  • Leak Detector
  • Vacuum pump

Indications You Need to Call an HVAC Technician.

After extended use, electronic appliances, especially air conditioners, develop problems. If they have outlived their active life, they may suddenly stop working. On the other hand, regular maintenance can help your air conditioner last longer. You should hire an air conditioning service to ensure that your air conditioner works well beyond its intended lifespan. If you see any of the indicators listed below, contact a specialist immediately or cease working.

1) Your Cooling System is Not Performing Adequately.

The air conditioner is an excellent device for quickly cooling a room. It works wonders in keeping the temperature cool amid scorching heatwaves. However, if the unit develops issues, it may blow hot air instead of cool air. Blowing hot air is the first symptom that the compressor is broken and needs to be repaired. However, there is no way to know unless a professional examines the issue with their trained eye. A blown fuse or capacitor could also be the source of the problem.

2) Odd noises coming from the unit

Like most machines and mechanical setups, unusual noises could indicate a problem, especially if the system is experiencing other temperature-related issues such as fluctuations or slow heating times. Strange or unusual noises do not necessarily mean immediately calling a professional. But, they are symptoms to be monitored. People who want to be proactive may contact one of their preferred HVAC technicians. It will ensure that there isn’t a more significant problem looming. Or they may ask to inspect the system for functional efficiency before a significant breakdown appears.

3) Weak Flow of Air

When the air conditioner labors to blow out air, it’s clear that the filters are not clean. Ducts and filters require timely maintenance and servicing by professional technicians. A dirty system and blockages are likely to unhinge parts and affect the motor and the airflow. If you have an AC suffering from this problem, immediately call for an air conditioning service. Neglecting this problem would only add to your energy bills.

4) Old Age

Your air conditioner has a lifespan, and repairs won’t be enough to keep it running at a certain point. Most HVAC systems last eight to ten years and need to be replaced. Annual HVAC maintenance might keep the system running more prolonged, but only a few years.

5) High Electricity Bill

If you start to notice that you are paying higher energy bills than ever before, you can blame it on a problem with your AC. The simplest way to explain it is that, if broken, the air conditioner uses a lot more energy than it should keep cooling your house.


HVAC systems tend to be pretty self-sufficient. But they do take some light annual maintenance to keep you warm in the winter and cool in the summer. And the good news is, a lot of that maintenance like cleaning and replacing filters and oiling bearings can be quickly done by you. But when something goes wrong, and you’re not quite sure what it is, it’s best to call in an experienced HVAC technician equipped with all the necessary HVAC tools.
