Understanding the Different Types of HVAC Systems

Considering a new HVAC system, you may be overwhelmed with all the available options. Talking to a heating and air conditioning company in Knoxville is an excellent way to get advice about the type of HVAC system that best suits your property. However, to get you started, let's look at some of the different types of HVAC you may want to consider.

Split Systems

A split system is one of the most common types of HVAC systems that might be recommended to you by a heating and air conditioning company in Knoxville. As you may be able to guess from the name, this is an HVAC system that is split into two separate units. One to handle cooling and the other for heating. They are easily identified by having an indoor and an outdoor unit. The Cooling unit is usually outside and uses refrigerant, compressors, and coils to help cool the air and a fan to keep hot air away. The heating unit is often found in a basement or some other storage space and uses gas to warm the house. The comfort level inside the home is controlled using a traditional thermostat to control the temperature.

Hybrid Split Systems

A Hybrid Split HVAC system is relatively similar to the traditional split system, but there are a few key differences. The main difference is that this type of HVAC system uses a hybrid heating system to help reduce energy costs. It can switch between gas and electricity. Gas-powered heating is faster, but electric is quieter and more efficient. The Hybrid Split offers the same advantages as a split system but conserves more energy and helps reduce utility bills.

Mini Split (Duct Free)

Mini Split HVAC systems are a great option if you want to control the temperature in different areas. There are two different components. First is the outdoor compressor and condenser unit; then, you have the indoor air handling units. They are relatively easy to install as they do not require ducts. Multiple air handlers can be run from a single exterior unit. A heating and air conditioning company in Knoxville will likely recommend a Mini Split system if you have a smaller space to heat and cool or if you already have a non-ducted heating system in place. Mini Splits can also be great for adding HVAC to a new addition on your property without extending the existing ductwork.

Packaged HVAC System

Another popular option is the packaged HVAC system which combines everything into a single unit. The compressor, condenser, and evaporator are all in one unit, usually situated either on the roof or close to your property's foundation. This unit is responsible for both heating and cooling the property. Since this is a more compact unit, packaged HVAC systems are great for homes with minimal space. They are very efficient and easy to maintain. However, they can be a little less powerful than some other units making them more common in warmer climates.

What Factors Should You Consider When Choosing an HVAC System?

Talking to a heating and air conditioning company in Knoxville is the best way to arm yourself with the correct information to choose the most appropriate type of HVAC system for your home or business. They will also be able to recommend particular brands or models that would work well in your space. However, here are a few of the different factors that you will want to consider:

  • Efficiency - You will want to choose an HVAC system with excellent energy efficiency to help minimize your utility bills. Look for the Seasonal Energy Efficiency Ratio (SEER) rating of the systems you might be interested in. Look for a SEER rating of 15 or more.
  • Capacity - Your HVAC system must be able to heat and cool your space effectively. That means you must have a unit that has enough capacity. Larger spaces need more capacity. This is measured in British Thermal Units (BTUs), and usually, the higher the BTU rating, the larger the unit's capacity.
  • Maintenance Requirements - All HVAC systems will require regular maintenance to keep them working optimally. For that reason, you will want to work with a heating and air conditioning company in Knoxville that can provide you with a maintenance or service plan to minimize the cost of upkeep on your new system.
  • Sound - Something many homeowners do not often consider when choosing an HVAC system, but they really should. If you have a low tolerance for noise, you need to talk to a heating and air conditioning company in Knoxville about which systems are the quietest ones to run.
  • Price - HVAC can be a substantial investment, so the cost will obviously be a factor when you choose which type of system to install. However, it should not be the sole deciding factor. Opting for the cheapest unit available may be false because there are more efficient options. Getting a range of quotes and looking at financing options is best.
