When it's time to replace your home comfort system, it's important to consider what a newer system can offer. Here are seven items to consider when purchasing an HVAC system:
Chances are, your heating and cooling system is the most expensive equipment you will purchase for your home. That's why it's important to choose proven products from a reputable manufacturer. The internet is a great way to find reliable reviews of products, though don't base your research on a single result, try to get a broad view of customers opinions. While it is wise to stick to the major brands, for those on a budget, there are some other brands that compete well for long term reliability.
A new ENERGY STAR®-labeled system, when properly sized and installed, can save ™ you up to 30% on your annual heating and cooling costs.* Plus, it may qualify you for utility rebates** in certain regions. Efficiency of the unit itself is the primary gauge of which unit you should be buying. It's capacity to heat/cool etc... and the amount of energy it takes to perform that task.
Air conditioners can produce sounds as high as 80 decibels. Look for technologies and features that help keep operating sound at a comfortable level. The noisiest types are the portable and in-wall/window mounted box style types. While they should not be ruled out of the selection completely, care assessing the noise levels should be taken when choosing this type.
With a typical furnace or single-speed air conditioner, indoor temperature can vary as much as seven degrees from the thermostat setting. A properly installed programmable thermostat gives you the assurance of precise temperature control*. Look for the more accurate digital read-out type controllers over manual thermostats.
To maintain proper moisture levels in your home, choose a thermostat that controls both temperature and humidity. These are the more advanced units but cover the essentials of comfort and climate control in the home and office. Running an evaporative cooler in a humid climate just does not make sense - as removing the room humidity will also remove the cooling effect (if any). Conversely, running a heater in a dry climate that dries out the air further can cause among other things, pain breathing and blood noses.
A typical furnace motor runs at one speed and circulates a constant volume of air, so it responds to changing comfort demands by repeatedly cycling on and off. This frequent cycling increases air stratification and stagnation. For optimal air circulation, choose a variable speed model. The controller should allow for a wide range of fan speeds to suit differing conditions.
One of the best ways to combat indoor pollution is to attach an air cleaner to your furnace or air handler. That way. you can have peace of mind knowing your system is working to capture small contaminants in every room of your home. In effect, an air purifier combined with your system will concentrate the cleaning effect making it more efficient at the same time, reducing duct contamination.
