A Guide To Choosing Your HVAC System

Choosing your HVAC system is one of the most important parts of managing your home. If you own an office or manage a duplex, you may need more than one air conditioner. Using these tips will ensure that you choose the appropriate unit, save money, and make the atmosphere inside the building as comfortable as possible. You should also research these units as much as possible because they all have different energy ratings, are made in different sizes, and work in certain situations.

How Large Is The System?

Your first choice should be the size. You need to know how large your furnace should be because that unit sits inside the house or building. A small furnace can help you with a small building, but you need a progressively larger furnace as the building grows larger. If you have multiple floors, you will need more than one furnace. There is no way that the blower for your downstairs unit can blow air downstairs and upstairs efficiently.

If you think that you can get by with just one furnace, you will spend far too much money on electricity, gas, or oil because the unit must work that much harder as GMR Mechanical‘s expert says.

What Is The Energy Rating?

You need to know the energy rating for the device if you plan to use it every day. You can check the energy rating for these devices, and you can compare them as you look at all your options. Most people who would like to save money should buy the unit with the best energy rating. At the same time, you may feel like it makes much more sense to invest in a unit that is a little bit cheaper, slightly less efficient, but does not waste your money.

Families must make decisions like this every day. If you do not have the money for an expensive unit, do not buy it.

How Is It Powered?

When you purchase an HVAC unit, you need to make sure that it is powered in the way that you prefer. You can get a furnace that uses gas, oil, or electricity. The furnace will tie in with the air conditioner, and the two will work together. No matter what you do, the air conditioning will use electricity.

Choosing the power source for your device is very important. Some families have a gas line for the house, and they prefer to use gas heat because it heats up so quickly. You may also choose gas heat if you have a gas range and existing gas appliances in the house.

You may use oil heat if you live in an extremely cold environment. Some older homes have an oil tank on the property, and you might continue to use oil heat because you can get a good deal for your oil deliveries.

If you have solar panels on your house, you should consider using electric heat. The solar panels can manage your AC and heat, and you will spend little to no money on utilities. You will save money on your budget every month, and you will avoid surprise bills because it was extremely hot or extremely cold.

Does The Outside Condenser Have A Traditional Or Modern Cage?

The condenser that sits outside the house is typically made with a large metal cage that protects the fan and condenser coils, or it may have a modern cage that is physically attached to the condenser. If you get an old-school cage, you can remove it yourself, clean the condenser coils, and check for leaks. If you get a more modern cage, you will need a technician to service the unit for you.

Some homeowners or property owners have enough knowledge to clean the condenser, and you may prefer to do that on your own. This might be especially important if you might find leaves and debris inside the cage. In some areas, this is not a problem. The problem is even more pronounced if you have dirt or sand inside the cage.

How Do You Manage The Unit?

When you install a new HVAC system, you should get a thermostat that will help you maintain a moderate temperature inside the building. New thermostats are often run with wifi, and you can change the temperature at any time. You can control how much money you are spending on heat or cooling, and you do not need to get out of bed to change the settings if you do not want to.

Newer furnaces have a light warning system that will tell you if there is an error. You can check the user manual for the flashing code, and you will know what the problem is. You can solve some problems on your own, or you can contact your technician for assistance.

Do You Have Ductwork In The Building?

If you do not have ductwork in the building, you need to decide if you want to add ductwork. You need ducts that will help you send air throughout the house. If you believe that ductwork will be too expensive, you can use a ductless system that heats and cools each room on its own. These devices are not the same as an HVAC unit, but you may not have any choice.

Some people even prefer ductless heating or air conditioning because you do not waste money heating or cooling rooms that you do not use very much. You will also prevent any leaks in the system that could heat or cool the utility closet/basement.


When you are ready to choose an HVAC system for your home or office, you should select a device that is efficient, affordable, and easy to use. You need to choose a furnace that will sit inside the house, and you must choose an accompanying condenser that will sit outside. If you do not have ducts, you may choose ductless AC or heat units for each room. You can keep the house comfortable, and you will save money at the same time.
