1Spring has barely sprung but now is the time to start thinking about your heating, ventilation, and air conditioning (HVAC) system. Having air conditioning in St Louis, Missouri during the summer is a must, so if you’ve been experiencing any of the following, it’s time to replace your HVAC system:

Uneven Temps Throughout the House

If some rooms are too hot and others are too cold, it’s a sign your HVAC system isn’t working properly. A new system will provide consistent temperatures — and comfort — throughout your home.

Excessive Dust

While this may simply be a sign your filters need changing, it can also mean your system isn’t filtering air properly and your indoor air quality is suffering because of it. Make sure to check your filters once a month, cleaning, and replacing them as needed. If that doesn’t alleviate the problem, you need a new HVAC system.


Your HVAC system should never make noise. If you’ve gotten familiar with the clanks and clunks of your system, it’s high time to let go.

Problems With Humidity

If your iced tea glass is sweating more than you are, it’s definitely a bad sign. Excessive humidity can lead to mold and other problems so it’s important to replace an ailing system with one that will help keep humidity down and air quality up.

Rising Energy Bills

One of the biggest indications your system is no longer energy efficient is a rise in your energy bills. If your bills have been steadily increasing, a new system is in order and will actually lower your monthly energy costs.

Of course, if the system is more than 10 years old, is often in need of repair or the warranty has expired, it’s also time to replace your HVAC.
