How to Find the Best HVAC Company

The HVAC Charlotte market is very competitive and there are a variety of companies in the area. To find the best company to work with, you need to have a basic understanding of the different options available. There are various types of furnaces, air conditioners, and heat pumps that you can choose from. It is also important to know your AFUE rating and how much energy you are using.

Air flow

Charlotte, North Carolina's HVAC system must be maintained in order to keep your home comfortable in the summer and winter months. But sometimes problems develop that can prevent a system from working as it should. In such instances, it can cost you a lot of money in the long run. A few warning signs can indicate that a problem is occurring.

One of the best ways to determine how well your system is running is to measure its air flow. Air flow measures the volume of air moving through the system per unit of time. The higher the number, the more air is flowing through the system.

Cubic feet per minute (CFM) is a common measure of air flow. When comparing systems with different efficiencies, a higher number signifies that more air is being forced through the system.

Filter surface area

If you are installing a new HVAC Charlotte system, it is important to measure the filter's pressure drop. This can reveal a filter that is not working as well as it could. Typically, higher efficiency filters have a larger pressure drop.

The best way to verify this is to measure the pressure before the air enters the filter. There are several ways to do this. For instance, you can install a test port outside the airside of the filter.

Another way to do this is to add multiple return air filter grilles. If you do this, the pressure drop should be much lower. In addition, you can increase the service life of the system.

Using a modified Wells-Riley model, you can calculate the impact of various levels of HVAC filtration. Here are some of the key metrics:

The aforementioned Wells-Riley formula was modified to include the effects of recirculating HVAC filters. It is based on assumptions about how human activity happens in an indoor environment.

AFUE rating

AFUE rating is an important factor when you need to choose a new furnace in Charlotte, NC. A furnace with a high AFUE rating can save you money on your energy bills. It also improves your home's comfort.

An AFUE rating is a measure of the amount of useful heat that a furnace is able to produce. Typically, furnaces convert eighty percent of their fuel into usable warmth. The higher the AFUE, the more efficient the furnace is.

To calculate a furnace's AFUE rating, you can use a calculator. These online tools can also be used to compare furnaces with different fuel types.

Using an AFUE rating for a new heating system can save you hundreds of dollars a year on your energy bill. This is because high efficiency furnaces use less energy and can be more affordable to run.
