Tips On What To Look For When Purchasing A New AC Unit

Your HVAC contractor will be able to help you select the best system for your home. The contractor will need to take into account the size and characteristic of your home.

One of the first things you should check is the heating and cooling capacity of your new HVAC system. Ask the HVAC technician about the reviews of the system.

BTU (British Thermal Unit)

Heating system capacity is measured by BTU (British Thermal Unit. This is equal to the amount of heat needed to raise a pound of water by 1-degree F.

When looking at BTU ratings, make sure you know whether it is input or output. Newer units have smaller input BTU rating since they are more efficient. Generally, the higher the BTU rating, the greater the heating capacity.

Cubic Feet Per Minute (CFM)

Cubic feet per minute is how many cubic feet of air that can pass by a fixed point per minute. This is essential for choosing the right capacity for your HVAC system.

Luckily, choosing the right size, capacity, and type of HVAC system is left up to your HVAC contractor. Too big and you’ll waste a lot of money and energy; too small, and you’ll overwork your system without ever feeling completely comfortable.

If your technician tries to size your new HVAC system based on square footage alone, they are doing it wrong.

2. HVAC System Cooling Size, Capacity, and Type

Check the capacity of your new air conditioner before purchasing it. This will assist you in choosing the best air conditioner unit for your home. Instead of British Thermal Unit (BTU), air conditioners’ cooling capacity is measured by Ton. 1 Ton is equal to about 12,000 British Thermal Unit Per Hour (BTUh). Learn why air conditioner capacity is measured in tons here.

As with your heating systems, it’s important to choose cooling capacity based on the size and needs of your home. You should always consult with a licensed and experienced technician about this. This will help you choose an air conditioning unit that is the right fit for your home.

3. HVAC Systems Energy Efficiency

Heaters and air conditioners consume a significant amount of energy. In fact, around half of our home’s energy use goes toward heating and cooling our home (U.S. Dept. of Energy).

Therefore, it’s important to check the energy consumption of your new HVAC system before purchase. This will help you to save energy and money across your home.

A furnace’s heating efficiency is measured by its Annual Fuel Utilization Efficiency (AFUE). The higher the AFUE number, the more efficient the furnace.

An air conditioner uses Seasonal Energy Efficiency Ratio (SEER) to measure its energy efficiency. The higher the SEER rating, the more energy efficient the air conditioner.

Heat Pumps

Heat pumps use a rating very similar to SEER, called the Heating Seasonal Performance Factor (HSPF). This number measures the heating portion of the heat pump. Again, the higher the HSPF number, the more efficient the unit.

For your new HVAC system to reach the optimum efficiency, a professional contractor will need to properly install it. The energy efficiency ratings mean very little if the unit is improperly installed. Learn more about the various ratings for different HVAC systems.

4. Noise Levels

Make sure your new HVAC system isn’t creating unnecessary disturbances around your house. Although the HVAC industry has made great strides to reduce HVAC noise levels, always check these levels. Ask the manufacturer and your installer about noise levels, measured in decibels (db). Look for systems that are under 80 db.

5. HVAC System Proper Maintenance and Indoor Air Quality

The maintenance of the furnace & air conditioning unit is crucial for them to work properly. Keep in mind that you will need regular maintenance for the unit. This is a requirement if you want to keep your manufacturer’s warranties in effect.

Neglecting regular maintenance will void almost all system warranties. Consider signing up for an HVAC maintenance plan. And don’t forget to change your air filter every 30-60 days!

Additionally, if indoor air quality is a problem in your home, ask your technician about effective ways to improve this. Various IAQ solutions are available, such as thicker air filters, air purification systems, humidification control, and ventilation products. Discuss your IAQ concerns with your contractor before any work begins.

Much Does a New HVAC System Cost?

The best approach to finding how much a new HVAC system will cost is to call a professional HVAC company. They will be able to send a technician to your home and provide an estimate.

We recommend obtaining several estimates and inquire about installation guidelines, certifications, warranties, insurance, and more.

Your new HVAC unit requires a professional technician to look at it. They have the knowledge to be able to work with the components the older systems have. This includes things like ductwork, wiring, ventilation, and the controls. It’s always important to hire an experienced HVAC company to make sure everything works in concert.

Make Sure To Contact A Professional HVAC Contractor

It is impossible to give you an estimate without inspecting your home and current system. You can expect to pay somewhere between $2,500 and $14,000, however this is contingent on many factors.

Taking all this into account you will be extremely happy with your new HVAC system and the comfort it provides.
