If you’re a homeowner in Jacksonville, you’ve probably witnessed firsthand how extreme weather can affect your home. Whether it’s summer heat waves that reach 100 degrees and cause your energy bill to skyrocket, or serve storms that bring damaging winds and flash floods, extreme weather can be very costly. Unfortunately, extreme weather can also affect your HVAC system, causing it to underperform, or worse yet, damaging it beyond repair when you need it the most. 

To help you protect your investment and keep your HVAC system performing efficiently, we’ve listed some of the ways weather can damage your system.  

Summertime in Jacksonville can do a number on your HVAC system and your power bills. With the summer heat and rain comes extreme humidity, which means your AC unit will have to work overtime to cool your home and remove the excess moisture from the indoor air. 

Most systems are designed to keep your home about 20 degrees cooler than the outside temperature. So, the hotter the outside air is around your HVAC system, the warmer the inside air will be. An easy way to lower the Freon temperature in your unit is to place a sprinkler near it and use water to cool it down. You can also try planting trees or tall plants next to your HVAC system to give it some shade. But be sure that your unit isn’t overcrowded and has plenty of room for air intake.  

Severe thunderstorms are quite common in Florida, and lately, hurricanes have caused extensive damage to the Jacksonville area. These types of storms produce strong winds that can strike your HVAC unit with flying debris. This is difficult to prevent, but tying down any loose objects nearby will help protect your investment. If your unit has been damaged by debris, have an HVAC professional take a look at it. 

Jacksonville is no stranger to flooding. From Hurricane Matthew to summer afternoon downpours, flash floods have wreaked havoc on homes and their HVAC systems. Your HVAC system is engineered to be impervious to rainfall, but not flooding. Water that exceeds 15 inches in depth can damage your system and require repairs or full replacement. 

Most concrete bases for HVAC systems are flush with the ground or only a few inches off it. Placing your system on a higher concrete base is a good way to keep it high and dry if flooding occurs. 

If you live near Jacksonville’s beaches, salt air can damage your HVAC system and shorten its lifespan. The sodium chloride in the salt air interacts with the aluminum on your unit, creating damaging corrosion. An easy way to help prevent this is by frequently hosing down your HVAC system with fresh water.

As simple as turning on a light can be, it is good to know the different types of light bulbs that are available to you, and which ones are the best for your home or office.

Below labels out the different types of lightbulbs you can purchase, and what the benefits are for each bulb so that you can choose the right bulb for you.


Typically the cheapest of all bulbs, it is also the most common, but they are not as energy efficient as other options out there. It has a warm light, and is very complimentary to skin tones. It also has a psychological appeal. Typically a bulb will last for 700 – 1,000 hours. They can also be used with a dimmer in the house.


These are a variation of Incandescent bulbs, but use a “white light” instead of a warm light, giving you the feel of natural daylight. Colors tend to appear more vibrant under halogen bulbs. While they are a little more expensive and burn at a higher temperature than incandescent bulbs, they are more energy efficient.

An important note is to NOT touch a halogen bulb with your bare hands. If you get any skin oil on the bulb, it could explode when it’s turned on because it can warm up too quickly.


Similar to Halogen, these are daylight-equivalent, but are often blue-ish and harsh, bright lights. These bulbs will typically last longer than an incandescent bulb, but are not able to be put on a dimmer. Typically, these are used to light large areas, such as an attic or basement.

Compact Fluorescent Lights/Bulbs (CFLs)

One of the more popular options. These bulbs last 10 times longer than an incandescent bulb, and consumer 1/4 of the energy as a them. They are quiet, and turn on instantly. They have warmer, color-corrected tones, and can be used anywhere you’d use an incandescent bulb. This is the second most common one found in homes today.

IMPORTANT: These bulbs do contain mercury, so extra care is needed to be safe. They will need to be recycled once they have burnt out.


LED stands for “light-emitting diode”. These bulbs are not really for everyone, even though they are energy efficient and long-lasting. They only provide directional light, which makes them idea for under-counter task lighting, but not to light up an entire room. These types of bulbs are also much more expensive than CFLs.

Basics of Electrical Power at Home

When owning a home, it’s important to understand how your electricity works, so you know what to do incase something goes wrong. Learning how your electricity works can be daunting for some, so we have provided the basics you can understand how electricity powers your home.


To start, electricity flows from a service provider, such as JEA in the Jacksonville area, through high voltages wires, like the ones birds like to sit on. The electricity then flows into neighborhood transformers where the current is reduced for residential and commercial properties – like your home or your office. A meter will record the amount of energy you are using, and route it to the electrical box or circuit breaker. The circuit breaker is like the nerve center of electricity for your home, and can usually be found in your garage or basement – somewhere that is not as obvious and might be a little more hidden.

Electricity typically comes in through 3 wires: 2 hot wires and 1 neutral wire. Each hot wires carries 120 volts and runs through the main electrical panel. Individual circuit units, which are connected to the main panel, control a section within your house, such as a light switch, and the hot wires power each of these circuits. And, each unit is connected by a circuit breaker, and when it is overloaded, it will trip or trigger, and electricity will stop flowing to the circuit, turning the unit and the connected devices off. Electricity travels in a circuit, meaning it flows in a circular route and starts and finishes in the same place and keeps repeating. The circuit will shut off the current of energy if the breaker is activated. The currents enter through a hot wire (usually black or red colored), and returns through a neutral wire (usually white). Most electricity systems use a ground wire, which is typically bare or copper in color. If a circuit breaker is tripped, the electricity will safely travel into the ground via one of these wires.

Dedicated circuits could have multiple areas or services that they control, such as outlets and light switches, but some appliances or heavy use items, such as a refrigerator or washing machine, may have their own circuit.

A current is carried through insulated copper or aluminum wires and is dispersed throughout your house. The larger the wire, the more current or ounce it can carry. If a wire uses more amps than it can carry, it will overheat. This is why a properly rated circuit breaker is very important. A switch completes a circuit when it is turned on, and disrupts it when it is turned off. There are several kinds of switches you can have in your house, such as dimmers or toggles.

A standard grounded outlet, which is the most common way to plug anything in, is designed to carry 15 amps. It has 1 slot a little bit wider than the other so that a plug can only be inserted one way. This is actually a safety feature that prevents power from running through an appliance, even when it’s switched off.

A ground-fault circuit interrupter (GFCI) outlet will turn off the power immediately if it detects the slightest change in current flow. These are most commonly found in kitchens, bathrooms, and outdoor areas. They typically have a 2-wire circuit and will typically have a “test” and “reset” button in the middle of the outlet. If an outlet stops working, you can push the “Reset” button to reset the circuit breaker.
