How much do you know about your Hudson heating and cooling? Whether you’re a first-time homeowner or someone who hasn’t thought twice about their HVAC, there are a few things you should know. Check out this guide to HVAC basics and have a better understanding of your system.

What is an HVAC System?

You’ve heard the term before, but do you know what it means? HVAC stands for heating, ventilation, and air conditioning system. It’s the equipment in your home responsible for keeping your home at a comfortable temperature. 

Furnaces, air conditioners, and heat pump all fall under the HVAC category. However, ductwork and thermostats also qualify as HVAC equipment. Everything works together in a system to maintain the temperature that you want.

Which Type of System Do You Have?

It’s a misconception that the term HVAC only refers to one type of heating and cooling system. In reality, HVAC systems differ significantly. Your system could include one or more of the following components:


A furnace is a type of heater that has four parts. First, there’s a burner that delivers burn fuel. Then, there’s the heat exchanger. Furnaces also have a blower and a flue that lets exhaust leave your home. 

Air Conditioner

As you already know, an air conditioner is responsible for cooling your home. It comes in several forms, but the split system is the most common. In a split system AC, an evaporative heat exchanger is inside the home, and a condensing unit is outside.  

Heat Pump

A heat pump is a form of heating and cooling. It’s more energy-efficient than most other methods but doesn’t provide as much heating power. Because Wisconsin is so cold in the winter, this isn’t a common type of heater. It uses the air from outside to heat a home in the winter and does the opposite in the summer. 

If you have a heat pump, you might also have an air handler. This piece of equipment circulates air around your home. 

Ductless Mini Split System

The ducts in a heat pump system lose cold or hot air, and that makes your system work harder than it needs to. To conserve more energy, some people opt to use a ductless system. This system relies on several indoor units as well as an outdoor unit. It allows for heating zones and makes it more affordable for you to add heating and cooling to a new addition in your home. 


There are two types of thermostats, and most HVAC systems have one. With the thermostat, you can control your HVAC system. A traditional thermostat is simple, while a controlled thermostat allows you to connect with other systems in your home and gives you smartphone control. 

How Much Does a New System Cost?

If your home is a brand new build or you have a home with an older HVAC system, you may need to install a new system. The cost of this varies greatly and depends on the size of your home. It also depends on these other factors:


Here in Hudson, the winters can be tough on you and your HVAC system. This is why you need a more powerful heater than you would in a warmer climate.


If your home has no ductwork, this will significantly increase the price of an HVAC installation. Your Hudson heating company may also need to install new ductwork if the old infrastructure isn’t up to current standards. 

The Average Cost

On average, the cost of a new HVAC system ranges from $5000 to $10000. The best way to learn more about the cost is to call your preferred HVAC technician.

Keep in mind that, despite the expense, installing a new system is sometimes cheaper than fixing an outdated one. New HVACs are highly energy-efficient, which saves you money on energy bills. Furthermore, they come with warranties and a reduced need for repairs. 

HVAC Maintenance

One of the most important things to know about any HVAC system is that it needs maintenance. If you don’t give your system the maintenance it needs, it will have a short lifespan and be in need of frequent repairs. 

The type of maintenance you need to perform depends on the system. If you have a system with ducts, you need to remember to change the filters every few months. Any system with an external condenser also requires some attention. If there are plants or trees growing near the unit, trim them back.

On your own, there’s only so much you can do to keep your system working well. That’s why you need a professional to step in. At least once a year, you should schedule a check-up of your HVAC system. A specialist can make sure everything is working the way it should and identify issues before they cause a major malfunction.

Making Your Hudson Heating and Cooling System More Efficient

If you have an old HVAC system, it won’t be as efficient as a new one. Today’s HVAC systems require less energy, which lowers your utility bills. But, if replacing your HVAC isn’t in the cards for you, there are a few things you can do to make your system more efficient:

Use Window Treatments to Your Advantage

In the summer, keep your home cooler by closing your window treatments during the day. At night on cold winter days, close your window treatments to keep the heat inside. 

Clean Your Filters

Dirty filters make your HVAC work overtime. For optimal efficiency, change your filters frequently.

Keep Registers Open

Air vents, also known as registers, open and close to control airflow. However, using them can make your system inefficient. Keep your vents open, or the HVAC will work harder than necessary.
