Have you recently purchased an older home without a central heat and air system? What we accept as a necessity was considered a luxury only a few years ago. Some older homes will have stand alone air conditioning units and perhaps an open fire but very few have a full modern heating and air conditioning system already installed. Unless of course it has recently changed hands and the new owners upgraded.
The good news is that it isn’t that difficult to install a new system into an older home provided you use a professional service such as that provided by Hatfield Heating and Air in SC. The HVAC contractor will sit down with you to discuss your needs and he will also review the house. He will then make suggestions as to the type of system you should install and where it should be situated.
You may want a furnace which is located in the basement or garage. Or perhaps you would prefer a heat pump. A furnace based system will heat air which is pumped through your home via a system of ducts. A heat pump will force air through the ducts extracting heat from the outside during winter and inside during summer. Heat pumps tend to be the more effective system and over the longer term offer lower costs. You can add air conditioning to either type of system. In split level homes the contractor will need to find space to place the air ducts but it sounds more complicated than it is in practice.
Depending on your personal requirements you may want a flexible system. For example if you are younger couple and intend on having or expanding your family, you will want a HVAC system that can be easily upgraded and improved as your family expands. Given that technology is improving all the time, you will want to deal with a professional contractor who will keep you updated and provide advice when and if you should be adding to or changing your systems.
