Can Rain Damage Your Outdoor Unit

April showers bring May flowers, but can it also bring June damage to your outdoor HVAC unit? With the rainy season here, you may start to worry about your items that stay outside of your home. Don’t let the rain get the best of you – or your outdoor AC unit. Here are a few risks to look out for that may occur with frequent rain.


Flooding damage

The biggest concern when it comes to heavy rains and an outdoor unit is flooding. Your HVAC unit is made to withstand different weather conditions – so if there is light to moderate rain happening, your unit should be just fine. However, if the rain gets to a point where flooding begins to occur, it could get messy. Your unit is not meant to be submerged in water, so flooding will cause issues.


Strong wind damage

Another issue that goes hand-in-hand with rain and your outdoor unit can be strong winds. During a storm, fast winds can pick up different objects and toss them around. If a large object gets tossed into your HVAC unit, there could be a problem. Aside from large objects, dust and debris can be blown into your unit and clog it up as well. Before you turn your unit back on, it’s best to check it out after a storm passes.


Rain itself won’t harm your outdoor unit, but what the rain brings with it just might. If you suspect a big storm coming, call a professional for advice on how to prevent any damage. Or if a big storm has just passed, call a professional to take a look at your AC unit before turning it back on.

Why Your HVAC System Smells Musty

With the summer months quickly approaching, you want to make sure your HVAC system is running smoothly. The cool air from your AC is exactly what you need with the temperatures beginning to rise – but what you don’t need is a musty smell coming from your air vents. There are a few common causes that make your HVAC system smell musty and for that smell to spread throughout your home, so let’s talk about them. And more importantly, let’s talk about the ways to fix the smell.


Causes and Solutions

Sometimes when an issue like this arises, we just want the bad smell gone for good – so we don’t even question what caused it in the first place. But it’s important to understand why it happened so that you can catch it the moment it happens again. Here are some of the common causes and how you can work with them to get rid of the smell.


Condensation build-up

If your AC is not draining correctly while it’s running, the build up of condensation can become like sitting water in your HVAC unit. This, in turn, will cause mold in your unit. So how do you fix this? Call a professional so they can find the mold build-up and clean it out properly. Once this is gone, the smell will be, too.


A leak in the air duct

When there is a leak in your air duct, even if it is small, mildew can find a way to grow there. If the cause of the musty smell in your home is from a leak in your air duct, call a professional so that they can get it checked for mold growth and patched up as soon as possible.


Evaporator Coil is dirty

Your evaporator coil is bound to get dirty at some point – just think of all of the dust and debris that flows by it on a daily basis. When this happens, mold will grow and thrive. The evaporator coil in your unit is in a dark, warm place, exactly what mold wants. So when this happens, call a professional and have them come clean out your coil.


It’s always safest to call a professional when it comes to having to get inside of your HVAC unit. Call Express Air at the first sign of your system smelling musty so we can fix it for you!



Most Common HVAC Problems in Florida

Having a working air conditioner in Florida is important. The hot summers can seem unbearable without one. However, we know that there are common AC problems in Florida, especially as the weather starts to heat up. Here are some of the most frequent issues that pop up across our state.


Dirt and dust

Having an outdoor unit can lead to an HVAC full of dust and debris – two things that do not work well with your AC unit. When dirt, dust and debris get into your unit, it can find a home on your fan and motor and lead to lower efficiency with the system as a whole. If this happens, call a professional like Express Air to come out and evaluate the issue. We can help you decide if it’s worth fixing the issue or better to replace the unit as a whole.


Low refrigerant

Having low refrigerant in your AC unit can be the result of a few things but the most common is either a leak or poor previous maintenance. Having a leak in your unit is a fairly simple fix by a professional. After the leak is fixed, you can expect the technician to test it out to ensure you won’t have this issue again soon.


Drainage issues

A clogged drain is never good – whether it happens in your sink, shower or AC unit, you know it needs to be fixed quickly. A clogged drain in your HVAC system will usually stop the flow of cold air and lead to a broken air conditioner. These are two things you do not want to happen as we head into the summer heat in Florida. A clogged drain is more likely to happen when the unit is being exposed to the outdoor extremes, such as hot, humid weather.

How often do I need an AC unit tune-up?

We don’t often put a lot of thought into our AC unit until the temperatures outside start rising or the unit begins to fail. We all have either heard of or experienced the horror stories of AC units going out on the hottest day of the year. Luckily, this nightmare is avoidable by regularly scheduling an AC tune-up. If that horror story didn’t scare you enough, we will give you a few more reason why getting a tune-up is a necessity to the livelihood of your unit.

How old is your unit?

The general rule of thumb when it comes to the frequency of AC tune-ups is once a year. If you have an older unit in your home, however, we recommend getting a tune-up twice a year. The older the unit, the more love and care it needs to ensure it can last you through the warm summer months.

Check the Calendar

It is important to check when your AC unit was last serviced. This will help to determine when you should call your local HVAC company. If you are a new homeowner or just purchased a new unit that has not been serviced before, it is standard to have a tune-up around the start of spring to make sure everything is up and running in time for summer.

The importance of tune-ups

Getting a tune-up on your AC unit is like getting a yearly physical at your doctor. A professional will come out and make sure all the parts of the unit are in working order and make note of anything that needs further service. Depending on the problem, most technicians are likely to fix it during your tune-up. Additionally, a well-working unit is an efficient unit – and an efficient unit is one that saves you money. Your unit might be working twice as hard to cool your home without your knowledge, unnecessarily spending more of your hard-earned money. Calling out a HVAC professional will ensure your unit is giving you the most bang for your buck.
