When it’s Time to Replace the HVAC System

If your HVAC system is over 10 years old, it may be time to consider replacing it. Repairing an older unit can be expensive and often times it’s cheaper to replace it completely.

High energy bills are a sure sign that it’s time to replace your system. Higher costs could be due to a rate increase or energy misuses but in many cases it’s an indication that the HVAC isn’t working efficiently. Book a visit MyAirToday | HVAC to clear your doubts.


The average HVAC unit has a lifespan of about 15-20 years. The age of your HVAC system is an important factor to consider when deciding whether to repair or replace it.

Older units typically become less efficient as they age. This means that they have to work harder to keep your home cool in the summer and warm in the winter. As a result, they tend to eat up your energy bills.

You can usually find out the age of your HVAC unit by looking at its nameplate with its branding information or its serial number. You can also ask your service contractor to check the age of your system if you cannot determine its age. It is a good idea to replace your HVAC before it goes beyond its lifetime.


When a home’s HVAC system starts losing efficiency, it often leads to increased energy bills. Energy efficient heating and cooling systems cost less to run and are better for the environment.

A small increase in energy bills is standard, but a sudden spike may be an indication that the HVAC system needs to work harder to heat or cool your home. This could mean that it is time for a replacement.

Having a new air conditioner or furnace with a higher SEER or AFUE rating will save you money in the long run. While it is a good idea to replace your HVAC with an energy efficient model, it’s also worth considering air sealing your home and insulating it properly as well. This will help you save even more on your energy bills.


The HVAC system is one of the biggest investments in your home. Yet many homeowners barely give it a thought until it breaks down, leaving them sweating in summer and shivering in winter. While a simple repair may save the day, at some point it will be less costly to invest in a new replacement.

If your unit is producing loud clangs, bangs, rattling or whistling noises it is probably time to replace it. These sounds are an indication of loose and broken components. Unusual smells are also a sign that your system is failing. A professional can help you decide whether to repair or replace your system. They can inspect your system and determine the cause of the unusual odors. They can then recommend the appropriate solution for your home or business.

Inconsistent Temperatures

If temperatures vary from room to room, the HVAC system is probably not distributing air evenly. This can be frustrating for people in the office, and it can also reduce employee productivity.

This problem can also lead to an increase in energy bills, which can be a sign of a worn-out or malfunctioning system. A newer, more efficient model can help reduce these costs and improve energy efficiency.

If your system is over 15 years old, it is likely time to replace it. A replacement will save you the cost of constant repairs, and it can improve your overall comfort. If you are concerned about the state of your system, contact a professional. They can inspect your equipment and recommend the best course of action.

Unusual Smells

Sometimes, a commercial HVAC system starts to smell. This could be from a number of things.

Unusual odors might indicate that your HVAC isn’t filtering or ventilating air properly. If you can’t get rid of the odor with air filters, this could be a sign that you need to replace your vents.

An acetone smell – similar to nail polish remover – could indicate that your HVAC has a refrigerant leak. This can damage your system and make your home or office less comfortable. It also poses a health and safety risk for you and your family or employees.
