What You Need to Know About Your New HVAC System


There are many factors to consider when it comes to choosing a new HVAC system. Some of the things you will need to take into account include the AHRI, the SEER ratings, the evaporator coil, the ACH, and the air ducts. If you have any questions about any of these factors, don’t hesitate to contact a contractor today.

Air ducts

Air ducts are an important part of your HVAC system. They recycle unclean air into clean air for your living space. However, your home’s air ducts can accumulate dust, debris, and even microbes. This is not good for your health and can cause serious issues.

The EPA recommends that you clean the ducts if you know how to. You can remove debris from air ducts with a vacuum with a strong suction attachment. Make sure to wear protective clothing and safety glasses for dusts and small particles can get into your eyes. If you’re not sure how to do it yourself, you can hire an HVAC Victorville professional to do it for you. There’s no shame in getting a professional for the job.

Evaporator coil

The evaporator coil’s surface area is huge, making it a great place for a lot of heat to be dispersed. However, this area also makes it a prime spot for mold to form. Mold growth will decrease the efficiency of the system’s heat transfer, causing it to work less efficiently.

Mold growth on the evaporator coil can be prevented by cleaning it on a regular basis. A licensed HVAC contractor will be able to use EPA approved biocides to disinfect it and help it remain in good working condition. However, heavy-duty cleaning requires removal and re-installation of the coils. This is mostly done by HVAC professionals since it’s not an easy work.

SEER ratings

A Seasonal Energy Efficiency Ratio (click here for more info) is a way to measure the efficiency of your HVAC unit. The metric is the ratio of the BTUs of cooling output to the total energy used to operate the system.

Getting a high SEER rating can save you money on your utility bills and reduce your carbon footprint. However, not all SEER units are created equal. To find the best unit for your needs, it pays to shop around and compare.

An AC unit with a higher SEER will cost you more up front, but will save you more money in the long run. It can also pay off when it comes to resale value. Fortunately, the SEER rating of your AC system can be easily calculated. This calculation is based on a few simple factors.

First, you will want to consider the size of your home. Your local HVAC company will help you figure out what size is right for you. Next, you will want to consider the weather. If you live in a climate where the summers are hot, it makes sense to invest in a high-efficiency HVAC system.

A new unit with a higher SEER will not only save you money on your energy bill, but it will also save you money on repairs in the future. You might even qualify for a tax credit if you buy a unit with a certain SEER rating.


Air Changes per Hour, or ACH, measures the amount of air exchanged in a room in an hour. It can vary depending on the type of building. Generally, a commercial building should have a minimum of four ACHs. For classrooms, it should be six to twenty ACHs.

ACHs are an important measure of indoor air quality, but not all buildings need them. Increasing the number of air changes can be beneficial but not for the long run. It is not necessarily a good way to reduce the spread of viruses and harmful pathogens. A better option may be to improve the ventilation system.

Having a good HVAC system is a crucial component of maintaining a healthy and safe indoor environment. In addition, it can help to minimize the spread of internal contaminants. But how can you know if your system is doing its job?

The first step is to determine how much fresh air you need to breathe. This can be calculated by multiplying the volume of the space by the required airflow. Using the airflow calculation, you can find out how many air changes are needed to keep the air in your building clean and healthy.

There are a variety of ways to calculate the number of ACHs your HVAC system requires, including using a tracer gas method.

An industrial hygienist measures the airflow of an area with a vane anemometer. The airflow is then converted into a cubic foot per minute. After a period of time, the resulting airflow is multiplied by the square root of the number of people in the room to calculate the number of ACHs.


The Air Conditioning, Heating, and Refrigeration Institute (www.linkedin.com/HVAC) is an organization that promotes energy efficiency and the environment. It develops and maintains standards for the heating, air conditioning, and refrigeration industries.

AHRI certified products are tested by a third-party to ensure that they perform accurately and meet manufacturer claims. AHRI certification leads to savings in energy costs and improved quality of life.

They are also an educational resource for the industry. It offers a database of shipment data and other industry information. In addition, it offers advocacy and analytical programs to help customers make more energy-efficient choices.

Their voluntary certification program ensures that a wide variety of products meet the manufacturers’ published performance claims. Using the latest edition of ANSI/AHRI 440, participants must comply with the program’s rigorous guidelines.

AHRI’s industry-leading certification program provides unbiased third-party verification of thermal performance. These tests ensure that a unit’s heat exchanger capacity is adequate. Combined with ASHRAE testing methods, AHRI standards provide a clear way to test a wide range of heating, air conditioning, and refrigeration equipment.

The products that they have are backed by more than 100 years of research. AHRI’s mark is a symbol of assurance that a product is accurate, quiet, and energy-efficient. Their certified HVAC units are evaluated by an independent third-party laboratory. AHRI’s seal of approval ensures that a unit has undergone extensive testing and is ready for installation.
