How to Shop for a New HVAC System

HVAC (heating, ventilation, and air conditioning) systems are growing in popularity, but it has long been an important component of every home. This article will discuss 5 important HVAC system features, and it will help guide you in buying the right one for your home. It is also important to consult with an experienced licensed electrician before you commit and ask the experts to install the unit.


Running from $6,000 to $12,000 for a 1,000 square-foot home, buying a new HVAC is a serious investment. Although pricing is important, it should not be the primary reason for your selection. The least expensive HVAC is not necessarily the best choice. Units that are more expensive usually have the most advanced features, as well as the latest energy saving technology.


Before you begin looking at HVAC systems, find out the precise area of your home in square feet. A unit that is too big or too small for your house will be inefficient during its operation. It will be either underutilized or overstrained. Either case will waste money.

Durability and Reliability

Buying a dependable HVAC unit is critical. Having no heat in the middle of winter or no air conditioning during a hot summer is both uncomfortable and costly in repairs. Do several comparisons of brands and models and study the reviews of HVAC buyers. Always ask questions regarding durability and reliability when you talk to salespeople about the systems they are selling.


The efficiency rating of an HVAC is an important way to determine whether it brings the best value for its purchase price. The higher the efficiency of a unit, the more optimal it will be able to perform. A highly efficient HVAC will decrease energy costs. A Seasonal Energy Efficiency Rating (SEER) from 10 to 16 is desirable for air conditioners. An annual Fuel Utilization Efficiency rating starting at 78% to 90%+ for furnaces and heaters is ideal.


Modern large HVAC systems typically need a licensed electrician/technician for a professional installation. The great majority of air conditioners and furnaces cannot be handled as a DIY project.
