Selecting And Replacing HVAC Systems In Humid Climates

Selecting And Replacing HVAC Systems In Humid Climates
  • Opening Intro -

    Humid climates can be challenging to live and work in. High humidity can wreak havoc on heating, ventilation, and air conditioning systems.

    In relation to that, are you thinking about doing some HVAC work on your house? 

    Maybe, you're looking to replace an old system or are looking to install HVAC for the first time.


If you fall into any of those categories, this article is for you. Here are the things you need to know when selecting and replacing HVAC systems in humid climates:

1. Find A Good Contractor For The Job

You don’t want to hire just any random contractor to install or replace your HVAC system. The first thing you’ll want to do is find one who specializes in installing such systems in humid climates. There are many HVAC systems available today, but some work better than others for your region’s unique climate conditions.

When trying to find a good contractor for the job, you must get estimates from at least three different companies before hiring anyone. This way, you can compare all the bids and choose which one is the most reasonable price-wise, as well as one who’ll do an excellent job with the installation or replacement job.

2. Check The Ducts

When it comes to humid climates, ductwork is a significant concern. Keeping your home adequately heated or cooled can be challenging if you have leaky ducts.

If you need to replace them, make sure you find a qualified HVAC professional who can replace them properly.

Duct walls can get wet because there’s no insulation between them, and it gets cold outside during the winter months. It causes condensation in the pipes, which leads to mold growth.

Water getting into electrical wiring is another common problem in humid climates. It can damage wiring because electricity and water don’t mix well together!  If your ducts are rusty or leaking, they may need to be replaced sooner than later.

3. Don’t Forget To Insulate

When selecting and replacing the HVAC system in humid climates, don’t forget to include insulation in your plans. Insulation helps reduce energy loss through the walls and ceiling of your home by preventing warm air from escaping during the summer months.

It also prevents cold air from entering your home during the winter months when temperatures drop below freezing levels outside.

When selecting a new air conditioning system for your home, ensure that the contractor insulates all ducts and pipes with insulation materials, like fiberglass or foam pipe, before installing them. It’ll help keep energy costs down by reducing how much energy an air conditioner uses to cool your home down during hot summer days.

4. Choose A Programmable Thermostat

The humidity level in humid climates can be a significant factor when selecting and replacing HVAC systems. With the help of a programmable thermostat, you can keep your home at the right temperature and save money by reducing energy costs.

The amount of moisture in the air can affect how quickly your air conditioner or furnace needs to work. So, if it’s too hot outside or too cold inside, it’ll run longer than necessary and use more energy than necessary.

With a programmable thermostat, you’ll have more control over how often your HVAC system runs. It means less wasted energy used for heating and cooling!

5. Select The Same Size System For Replacement

When replacing an older heating and cooling system, select a new system of the same size. It’ll ensure that your existing ductwork will be able to handle the new system.

If you replace an older heating and cooling system with one that’s too large, it can lead to overcooling and ice buildup in the ducts. It can also cause low-pressure problems with your new system.

If you’re considering replacing your existing unit with a bigger one, think again!  Bigger isn’t always better for your home’s HVAC system.

A larger unit may not be able to handle the extra moisture without overworking itself or causing other issues, such as condensation on windows and walls, mold growth, and higher utility bills due in part to higher energy consumption.
