How Do I know It's Time to Replace My HVAC System?

May 23, 2022 | Blog

If you are experiencing issues with your HVAC unit or are curious about replacing the unit itself, then you have come to the right place. Mission AC & Plumbing has you covered with the information you need to identify potential issues and provide professional solutions.

Red Flags For HVAC System Replacement

Strange Noises

If your HVAC unit is groaning like it has a stomach ache then it might be time to replace your AC unit. Excessive loud noise and unusual sounds are signs of your HVAC needing replacement.


If your air conditioning unit is over 10 years of age then it is nearing retirement. Think back a decade ago to how different your cell phone, television and computer were. That innovation in technology also affects the evolution of HVAC systems. There are more efficient systems that incorporate contemporary technology making decade-old HVAC units obsolete. We promise your HVAC unit will not take it personally when it’s time to replace it.

Odor Issues

The last thing homeowners want is an HVAC unit blowing funky smells throughout the home. If you have noticed a stinky odor permeating inside your home, then it might be due to an HVAC that needs replacement.

Frequent Issues And Maintenance

There is a difference between annual checkups and excessive maintenance. Homeowners should take care of their air conditioning unit by getting regular inspections. However, if your unit is constantly breaking down then this is a sign that your HVAC unit needs replacement.

Inflated Energy Bills

One of the most noticeable signs for homeowners that there may be an issue with their AC unit are when the energy bills are inflated. If an HVAC unit is using disproportionate effort when trying to work, it will also increase the price of the bill. This is a major red flag that homeowners should not ignore.

What Is The Average Lifespan Of An HVAC System?

Air conditioning units are considered outdated by professionals once they have passed 10 years of use. However, regular maintenance can extend this period by a few years. For those wondering how often you should replace your ac unit, the answer is typically 10 years. Check out our AC tune-up services to help extend that number.

What Is The Best Time To Replace Your HVAC System?

The best time to replace an AC system is when HVAC businesses are less busy. This can help with the affordability and convenience of scheduling an appointment. The fall and spring seasons come before the extreme weather conditions of the winter and summer. Do not wait until the Houston heat is scorching the city before you decide it is time to get a replacement.
