Signs Your HVAC System Needs Replacing

Everyone knows that HVAC systems are not perfect, but how long do HVAC systems last? There’s a lot to know about your system’s operation and efficiency, especially considering how new systems are becoming more efficient and higher-tech every year. This article will help you know the signs that your system might need to be replaced so that you can stay cool and save money.

How Long Does an HVAC System Last?

How long an HVAC system lasts depends on your system and where you live, but in general, you can expect a Houston HVAC system anywhere from 12-15 years, depending on how frequently you use your HVAC system.

What Is the Lifespan of an HVAC Unit?

The lifespan of an HVAC unit depends on many different aspects of the system. Here are some deeper dives into each part of an HVAC system.


Furnaces last between 15 to 20 years, depending on the quality of the furnace. A furnace is replaced when the heat exchanger starts leaking. We offer furnace maintenance services if your furnace has an odd smell, is not warming up your house and any other problem you might be facing..

AC units

AC units typically last between 12 and 15 years, depending on how well they are cared for by the homeowner. Many factors can affect the lifespan of an AC unit, such as how well it was installed and maintained over the years. Being in Houston, TX with hot weather affecting residents most months, our units see much more usage than a home in northerns U.S. Because of this and other factors, Houston Homeowners usually see a shorter lifespan of their AC system ranging between 8-10 years before problems begin to arise. If your system is not performing how you would like or if it is in need of repair, our comfort experts will come out and discuss all of your options with you.


Boilers typically last between 20 and 35 years but, in some cases, can last as long as 40 years with continuous maintenance. Boilers contain many parts that can wear down over time, including the motor, heat exchanger, carbon monoxide sensors, etc.

Heat Pumps

Heat pumps typically last between 8 and 15 years, depending on the quality of the heat pump. If you want your heat pump to last, you should have your system professionally serviced regularly and keep it well maintained.

The right time to replace your HVAC system can come at any time. If you are unsure if your system will make it through another summer give The Chill Brothers a call at (832) 478-777 for a no obligation assessment to learn all of your options.

Signs Your Air Conditioner Needs to Be Replaced

Some common issues homeowners face that lead them to replacing their old system are high energy bills, loud systems, house is not cooling to the selected temperature and many more reasons. Here are a few things that you can check to test the condition of your current system.

Check for Airflow Issues.

First, you need to know whether your system is operating at peak efficiency. If your system is only using one air handler instead of two, or if it is working harder than usual to cool down the area that it needs to cool down, then this could be a sign that the unit needs to be replaced.

High Energy Bills.

If your energy bills are getting higher than usual, you may have an HVAC system that is using twice or three times the amount of energy to cool your house. Our trained and certified technicians can clean up your system and inspect it to determine if it’s time for a replacement.

Fouls Smells.

When the air isn’t properly circulated, it can cause foul smells, especially with an older system. If you smell something that resembles burning when your system is on, check if you have any duct leaks.

Tips to Care For an HVAC System

Here are a few tips to take care of your HVAC system

Change Filters

Make sure to change your filters at least once per month. If you do this, your system will be able to continue to operate at maximum efficiency and keep your family safe from the dangers of poor air quality.

Clean the Heat Exchanger

You should also have your heat exchanger cleaned every couple of years. Doing this will ensure that you don’t have any issues replacing the parts that can reduce its efficiency over the years.

Have Regular Maintenance

It would help your HVAC system tremendously if you have it professionally inspected, cleaned, and serviced twice a year. You also need to check the wiring and any other parts that can cause your system to become inefficient and ultimately need replacing.

A properly maintained HVAC system can help you save money in the short and long run. The Chill Brothers in Houston, Texas offer the best Lennox upgrades and maintenance services.
