Home Air Conditioning Systems Are High Tech.

Today, your choices of home air conditioning systems includes more high tech, variable speed furnaces and air handlers. These systems tend to run longer at lower blower speeds in an attempt to improve comfort and increase dehumidification. This is great when you have a well-designed tight, balanced duct system.
A single-speed furnace or air conditioner comes on full-blast no matter what. That may be okay in the dead of winter or heat of summer, but in the spring or fall, when outdoor air temperatures are less extreme, a single-speed unit may heat or cool rooms too quickly.

Besides this basic functionality on forced air HVAC systems, there are only about two real comfort feature options. The two features that can increase your comfort, though, are noteworthy and valuable. They are two-stage heating, and self-adjusting blower speeds. Both of these are available for forced air furnaces.(Remember, it's the blower system of your furnace that moves the cool air from the evaporator through your duct systems.)

The benefits of a two-stage furnace with variable speed blower are that it makes you more comfortable due to more even temperatures throughout the home, maintains a more steady
temperature (keeps the house at nearly the exact temperature you set your thermostat), increases your air conditioning efficiency about 8% (if you have air conditioning), has a lower operating cost (due to a DC voltage variable blower motor), increases efficiency of any attached air cleaner, and is quieter than other furnaces. The benefits of a two-stage furnace with multi-speed blower
are similar to the Two-Stage Variable Speed models. However the Two-Stage Variable Speed models are even more quiet, even more electrically efficient, and even more comfortable.

Air Conditioning Oversizing Causes and Effects Part #2

When it comes to this topic, Doug Rye, a nationally known speaker says it this way, "DO NOT, DO NOT, and I repeat DO NOT let anyone install your air conditioning system without having the experience and expertise to size it correctly for your home.  Too many homeowners allow the contractor to estimate or guess the size of the system.  This nearly always results in an uncomfortable home. Make sure  you ask how they sized it or did they just install the same size that was in their before.  A reputable contractor will be happy to provide  you with this information.

Air Conditioning Oversizing Causes and Effects Part #1

Customers depend on the expertise of contractors in selecting air conditioners. Yet contractors generally size air conditioners at least a half-ton larger than necessary and often oversize by a ton or more. Even the most conscientious contractor is driven to avoid call-backs (or even lawsuits). An oversized air conditioner can mask problems from duct leaks, improper flow across the coils, and improper charge.
