Did you know? 

HVAC systems have been comforting mankind for nearly 600 years. From Roman’s hypocaust, handheld fan, and high-pressure heating system to modern-day HVAC, they have gone through a long evolution to pace up with time. 

Get yourself educated on interesting things about HVAC with the quick guide given below.

What is an HVAC System?

HVAC is an abbreviated form of Heating, Ventilation, and Air Conditioning. It is a combined system of the furnace, fan, air conditioner, heat pumps, boilers, and air purifiers. This way, the HVAC system ensures thermal comfort as well as improved air quality. 

What is the Average Life Span of HVAC Systems?

Well, the life expectancy varied based on the maintenance and components. Generally, an HVAC system lasts 10-15 years with proper maintenance. AC may have a life of 15-20 years while humidifiers may last 8-10 years. 

What are the Types of HVAC Systems?

There are generally three types of HVAC system which are given below:

  •   Centralized: 

As the name suggests, a centralized system is a single system located in a single zone to meet the HVAC needs of a building. 

  •   Packaged:

They are an all-in-one heating and cooling system that is ideal for houses that lack enough space to accommodate a furnace or an air handler. It is generally placed on the side of the property or roof. 

  •   Individual:

They are the decentralized system being used for the individual units across the building or smaller homes. 

How Often the HVAC System Should Be Serviced?

Given that the HVAC system has to work hard to maintain the comfort of your home, it requires timely maintenance. Make sure to have it turned up once a year. 

What are the Signs of HVAC Problems?

Weird Noises: 

If your HVAC system makes strange sounds like clanking or squealing, something’s wrong, possibly with belts or motors. Ignoring these noises could lead to bigger issues.

Weak Airflow: 

If air barely comes out of your vents, it might be a clogged filter or a faulty fan. Change filters regularly and get routine maintenance to avoid airflow problems.

Uneven Temperatures: 

Rooms that are consistently too hot or too cold could mean issues with the thermostat, ductwork, or the HVAC unit itself. A professional can help fix these problems.

High Energy Bills: 

If your system is inefficient, it will use more energy, leading to higher bills. Regular maintenance and prompt repairs can help keep energy consumption in check.

Short Cycling: 

If your HVAC system frequently turns on and off, it’s called short cycling. This puts stress on the system and affects temperature control. A professional is needed to diagnose and fix this issue.

Leaks or Moisture: 

Water around the unit or in the ductwork is a serious problem. Leaks can harm the environment, and moisture can lead to mold. Call a professional to address these issues promptly.

Strange Smells: 

Unpleasant odors from your HVAC system may indicate mold, electrical problems, or even a dead animal. Don’t ignore these smells; address them promptly to maintain a healthy living environment.

How to Care for Your HVAC System?

Keep Outdoor Units Clean: 

Trim vegetation around the outdoor unit and clean it regularly to ensure proper airflow.

Schedule Professional Maintenance: 

Regular maintenance by a qualified technician helps identify and fix potential issues before they become major problems.

Use a Programmable Thermostat: 

Set temperature schedules to match your routines and save energy. Some thermostats even allow remote control from your smartphone.

Check and Seal Ductwork: 

Seal leaks with duct tape or mastic sealant and add insulation for better energy efficiency.

Monitor Refrigerant Levels: 

Be aware of signs like reduced cooling performance or hissing sounds, and contact a technician if you suspect a refrigerant issue.

Keep Vents Unblocked: 

Ensure all vents are unblocked for proper airflow, maintaining optimal performance and energy efficiency.

Investigate Unusual Noises Promptly: 

If you hear strange sounds, investigate promptly. If you can’t resolve it, call a professional technician for help.
