Your Guide for Choosing the Perfect HVAC System


Choosing a new HVAC system can seem like an overwhelming task, especially if you don't know much about these systems in general. An HVAC company in Acworth can provide valuable information to help you choose the best system, but you're more likely to get exactly what you need if you know a little about HVAC systems before talking to a contractor. Here are the basics of HVAC systems to help you make an informed decision.


Don't Overlook Ductwork

Whether you're new to an HVAC system entirely or looking to upgrade, be sure to consider the ductwork. If your home hasn't had any HVAC system installed previously you'll need to have ductwork installed throughout your home. Even if your home already has ducts, you should have them inspected by the HVAC contractor to make sure they're in good condition and that they're properly installed and insulated. Improper ductwork can keep the highest quality furnace or air conditioner from doing its job efficiently, so make sure you don't skip this step.


Furnace Basics to Know

Another important thing to research when considering HVAC in Acworth is the number of different types of furnaces. Older furnaces generally run at one setting, which is called single-stage heating. This simply means that the furnace runs on high until the set temperature is met and then shuts off. A more energy efficient type of furnace uses two-stage heating. This means that the furnace can run at a lower setting to keep the heat more consistent without using as much energy as single-stage, full-powered heating. A more recent technology uses variable speeds to maintain the temperature.


Choosing an Air Conditioner

There aren't a lot of differences overall in how air conditioning units work, but there's a lot of difference in efficiency, which is the most important thing to consider. While more energy-efficient models will have a higher upfront cost, you can think of it as an investment because you'll quickly recoup the extra costs in utility bill savings. Air conditioner efficiency is based on a Seasonal Energy Efficiency Ratio (SEER). SEER ratings start at 13, with 16 being considered a good rating for energy efficiency compared to the cost of purchase. Aside from the SEER rating, you'll want an AC unit with an aluminum evaporator coil because they're more resistant to corrosion and leaks than copper and steel coils.


Consider All-in-One Heating and Cooling

You may want to think about all-in-one heating and cooling, which uses a heat pump. This basically allows one system to take care of the heating and cooling by switching a valve that reverses the direction that the refrigerant flows to either pick up heat or remove heat. Heat pump systems are the most energy efficient systems available and will save you quite a bit of money on utility bills.
