5 Questions To Consider When Buying An A/C Unit

Air conditioners don’t last forever. If you notice that your air conditioning system isn’t functioning as efficiently as it should, it might be because your system is an old hunk of metal, and it frequently breaks down or needs repair. It’s time to consider replacing your HVAC system.

Buying a new air conditioner can be a stressful experience as it is a big purchase! You need to make an informed purchase and there are many factors to consider. Getting a new air conditioner really needs some thought. Most of us are not quite knowledgeable when it comes to home appliances and technology. Here are five things for you to think about when buying an A/C unit:

How Large Should the Air Conditioner Be?

Finding the perfect AC depends on a lot of factors including room size, ceiling height, insulation, the size of windows, and level of sunlight. Selecting a small unit will be too underpowered to cool your home. An oversized unit, on the other hand, will cool the room quickly, but will inefficiently cycle on and will cost you more money. An HVAC industry standard calculator called “Manual J load calculation” can help you figure the perfect air conditioner that you need. It will give you an accurate calculation to cool your home efficiently and effectively.

How Efficient Is the New System?

When it comes to air conditioner systems, it’s always important to determine the efficiency of a system, as the wrong one will suck more energy and money from your wallet. Consider the lifetime operating costs, not just the upfront value. When choosing an air conditioner, always look for Seasonal Energy Efficiency Ratio (SEER). A higher SEER rating means more efficiency and lower operating costs.

What Technology Do I Need?

Nowadays, there are many technological advancements to consider than just choosing cold air. Geothermal systems are some of the most energy efficient available as it uses the cold temperature underground instead of the air outside. Ductless mini-split air conditioners are usually mounted on a wall or a ceiling, instead of moving cool air around your house as part of a central system they condition one room at a time. You should also consider reversible heat pump systems. They work as an air conditioner, but can also act in reverse as a heating system during winter. Take into consideration that there are low-noise models available as well.

What Is the Installation Timeline?

It helps to know the timetable for each phase of a project. Your new air conditioner estimate should include the cost of installation and the cost of the unit so that you can compare and weigh your options to other companies’ estimates. Note that some models will impact installation time periods and costs, so you might want to consider this information as part of the decision-making process.

What Is the Total Cost?

There are several factors to consider that can affect the total cost of a new air conditioner, such as the size of the system that you need, your AC unit’s overall efficiency (the higher the kilowatt capacity, the more it will cost), whether you need a new thermostat, and whether your house requires a substantial amount of ductwork. In addition, the cost of hiring a professional to install the unit needs to be considered. It’s wise to get quotes from several providers and compare those quotes so you can get the best overall deal.
