8 Common HVAC Problems You Can Expect to See This Summer


You rely on your home’s HVAC system to keep your space comfortable during the warmer months of the year. This means the system sees a lot of wear and tear every day.

Believe it or not, the average home HVAC system lasts for about 15 years with proper care and maintenance. If you don’t stay on top of routine maintenance, you risk having to replace the system far sooner than you should.

The key to keeping up with maintenance is knowing what common HVAC problems to watch out for so you can call your repair technician quickly. Here are a few of the most common issues you’ll want to watch for during the summer months.

  • Poor Airflow Through the Vents

Anytime your air conditioning system turns on, you expect it to put out a steady supply of cool air into each room in your house. When the system is working properly, you’ll be able to feel a consistent breeze anytime the air conditioner turns on.

When there’s a problem with the system, you’ll likely notice less airflow coming through each vent.

This change in airflow is often caused by dirty or clogged air filters. Replacing those filters should fix the problem and leave you with a cool, comfortable home.

  • High Energy Bills

During the heat of the summer, it’s normal for your energy bills to increase. This is because you’re relying on your air conditioning system more often. The more often it turns on and the harder it has to work, the more energy it will use.

But you should be able to justify those increases. If your energy bills keep going up without any clear reason, it’s time to call your HVAC repair company. The problem may be something minor like a faulty thermostat, but it could be more severe.

They’ll be able to assess your home’s HVAC system and identify the issue quickly. Once they find the cause of your increased energy use, they’ll be able to make the necessary repairs.

  • Warm Air When the System Turns On

When your HVAC system is in good shape, the air conditioner should put out cool air anytime it turns on. If you notice warm air coming through the vents, you have a serious problem with your air conditioner.

There may be a refrigerant leak, keeping the system from being able to cool the air it puts out. Or you may have frozen condenser coils outside that keep the system from working as it should.

Your trusted HVAC contractor will be able to inspect your system and find the cause of the problem.

  • HVAC System Not Turning on at All

There are few things worse than adjusting the thermostat only to find that your air conditioning system doesn’t respond. In most cases, the problem isn’t due to a fault in your HVAC system. Instead, it’s an issue with the thermostat.

Thermostats don’t last forever and are cheap to replace. However, it’s always best to let your HVAC contractor install a new thermostat for you.

This way, you’ll know that your HVAC system will turn on without a problem. Even better, you won’t have to deal with complicated wiring and dangerous electrical connections.

  • Unexplained Loud Noises

Even the quietest HVAC systems make noise when they turn on. However, after living with your system for even a few weeks, you’ll know which noises are normal and which are overly loud or unusual.

If you start hearing strange noises or the normal noises your system makes start getting louder, don’t ignore it.

Call your HVAC company immediately. Those loud noises are a surefire sign that your system is struggling. The longer you let those noises continue, the more extensive the damage will get.

By getting your system repaired quickly, you’ll reduce the severity of the damage and may end up saving money on repairs in the long run.

  • HVAC System Not Keeping Up

During the warmest part of the summer, your HVAC system should still be able to keep up with the changing temperatures. Unfortunately, HVAC systems start to lose their ability to keep up with warm temperatures as they age.

If your system isn’t putting out enough cold air to help keep your home comfortable, it’s time to call your HVAC repair company.

They’ll be able to inspect the system and tell you if the issue is repairable or if it’s time to replace the entire system.

  • Fuses Keep Blowing

Your air conditioning system works with the help of a compressor. The compressor pushes the refrigerant inside the unit throughout the system so it can produce the cold air you rely on.

If the compressor starts to fail, you’ll likely notice an increase in electrical issues throughout your home. The most common issue is frequently blown fuses.

Those blown fuses aren’t just inconvenient. They indicate serious electrical problems with your system. Your HVAC contractor will be able to assess the electrical components and fix any problems as soon as they find them.

  • General Lack of Maintenance

Arguably the most common HVAC problems all come down to one thing: a general lack of maintenance. Think about how often you’ve gotten your system tuned up in the past.

Most systems need tune-ups at least twice each year, once in the spring and again in the fall. If you can’t remember the last time you scheduled a tune-up, it’s time to call your technician.

The sooner you can give your HVAC system the TLC it needs, the less likely it is to have serious problems in the future.

Watch for These Common HVAC Problems

You need your HVAC system to work well year-round. Watch for these common HVAC problems throughout the summer.

If you notice even a single one, don’t wait. Call your repair technician as soon as possible. They’ll be able to get your system back into good working condition in no time so you can stay comfortable year-round.
