Air conditioners play a critical role in the home, helping to circulate air, maximize comfort, and reduce humidity. While a central AC system can last up to 20 years, most people will have to buy one at some point. Below are some factors to consider before buying a new HVAC unit from All Service Air Conditioning & Heating Inc.

Finding the Right Installer

There are many places online, such as Angie’s List, where potential customers can read reviews and ratings on local companies. Once a customer makes a short list of contractors, they should call each and ask for quotes. When getting quotes, the customer should ask for a recommended unit’s make and model so they can make accurate comparisons from one company to the next.

Installation Pricing

When a homeowner replaces or installs an AC unit, there are two prices: the unit cost and the installation cost. A customer may be able to save a little money by buying the unit themselves at wholesale price, but they still have to pay for installation from a Residential HVAC Service.

Unit Size

The unit size is critical in overall home comfort. The HVAC unit should be big enough to cool the home but not so big that it loses energy efficiency. A too-large system will cycle rapidly, consuming more electricity and lowering efficiency. A unit that’s too small will not be able to cool the whole home on a hot day. Before making a recommendation, the contractor should come out for a load calculation to determine the right size unit for the home.


An HVAC unit’s efficiency is measured by SEER (the Seasonal Energy Efficiency Ratio), and the government has recently mandated that all new AC units have a SEER rating of 13 or more. Units with SEER ratings of 14-22 are considered energy efficient.


Most HVAC unit manufacturers recommend yearly Residential HVAC Service. A homeowner’s failure to properly maintain the unit can void the manufacturer’s warranty. To simplify the maintenance process, consider a service contract with a local HVAC contractor. These service plans can find small AC problems before they become big and expensive.
