The need for a new HVAC system can happen at any time of year for a multitude of reasons. They can make the quality of life at home a lot more comfortable with heating and cooling when needed. However, these units are a little complex. Shopping for a new one can be challenging if you don’t know what you’re looking for, but that’s where Busy Bee comes in. We’ve outlined some considerations you will need to make when purchasing a new HVAC system.

Types of Air Conditioners

Central Air Conditioning Unit

A central air conditioning system is sometimes referred to a “split unit” because the entire system is both inside and outside the home. The air travels via the air ducts, and the refrigerant circulates between an indoor coil and an outdoor condenser. The refrigerant will cool the air, and a blower will push the cold air through the ductwork distributing it throughout the house. Your thermostat found inside the home will communicate with the unit to set the temperature.

Split Ductless System

The split ductless system has a compressor outside like the central a/c unit, but there are multiple blowers set up inside the house. These devices are usually mounted high on the wall and are often referred to as air handlers. The connection is a thin conduit that contains a condensate drain, refrigerant tubing, and a power cable. The central unit has a network of ducts and vents that move the cold air throughout the home, but the split ductless system will only cool the room in which the air handler is mounted.

Get the Right Ductwork

Putting in a new HVAC system allows you to choose a unit that best suits your needs rather than inheriting one that doesn’t have optimal performance. The system you end up choosing could be influenced by the ductwork inside your home. Ducts are the tubing or conduits that are often made from aluminum. Climbing into your attic and you can more than likely see what they look like. If you already have the ductwork, adding a central unit will probably work out to be cheaper than to go with a split system.

Hire an HVAC contractor to assess the size of your ducting. They can confirm the size you have will match the unit you are wanting. Too small and they operate at a very noisy level. When they are too large, it can run inefficiently.

What You Should Consider When Installing a Central AC Unit


The size of your machine is critical. What you want is a machine that will run efficiently. Units that are too large won’t run effectively. A/C systems both remove heat and dehumidify the air. Over time the unit will start to run a little slower because the unit is cooling the room before it can remove humidity. It will end up feeling damp. Have your contractor measure your home and advise you on a size based on the square footage.


You’ll hear this term a lot when you are getting a new unit. It describes the amount of electricity used in relation to cooling. Regulations have passed that make it mandatory for manufacturers to produce systems with a minimum SEER rating of 14. Get a unit that has a 15 SEER rating or higher.

Programmable Thermostat

Newer systems will almost always come with a programmable thermostat, but you will want to check. Having one alongside your unit will give you the option to change and set the temperatures when you aren’t home. It gives you the chance to save a little bit on your energy bill. Programmable thermostats are also slightly more accurate at reading the temperature.


Buying a new HVAC system through a contractor should come with a maintenance plan. The maintenance plan comes with regular check-ups to ensure your system and the ductwork is running smoothly.

Finding the Right Contractor

The success of your new system revolves around the quality of service from your contractor. Here are a few tips for hiring a heating and cooling contractor.

  • Confirm they are insured – installing or upgrading a unit is complicated. Make sure they have insurance in case of damages.
  • They are BBB accredited – the Better Business Bureau is dedicated to helping consumers get the best contractor. Look for the BBB logo on their website.
  • Read Reviews – Customer reviews will tell you enough about what it’s like to work with the contractor. Search Google and try to find one with four or five stars.
