In this article, we will talk about the most common heating and cooling systems and whether or not you should think about replacing or repairing your unit. Most, if not all, modern homes these days have central heating and air that comes from an outdoor or indoor unit – sometimes even two different units on the property, an indoor and outdoor one. These are usually operated by a thermostat placed inside the house, which allows the homeowner to control the internal temperature of the home at the push of a button.

The first thing to always consider when you’re thinking about replacing or repairing your heating or cooling system is the efficiency of the system. There are some central heating and cooling units that are over 15 years old that still work perfectly. That having been said, some of these units use up to twice the amount of electricity as a low-end/brand new unit.

External Components

Another thing that you must inspect and assess is the condition of the ductwork and other external components.You can purchase the highest efficiency heating and cooling system out on the market today but if you have poor ductwork and air transfer systems this will do you no good.

In the average home, ductwork leaks up to 30% of air before it reaches your living space. Most technicians can run a ductwork leakage test by sealing off the vents in order to measure how much air escapes the system.

This is especially useful to ensure that you’re getting the most effective that is possible from your ductwork system. In the event that the ductwork and air transfer systems are both fine, you can then assess whether you need to replace the unit itself or repair it.


The next thing we will talk about is the quality of insulation and the R-value of the type of insulation you have chosen in your home. If your home is poorly insulated putting in a new unit it is almost not worth the time or effort.

Having poor insulation also puts much more strain on your existing unit, as it will continue to use more and more power – lowering the efficiency at which you heat or cool the home. Assessing any air gaps or leaks in the insulation is one of the best ways to ensure that you get out with as much money left in your pocket as is possible.


Any time a replacement is made you want to ensure that the system is the right size for the building or home that you’re planning to heat and cool. Most air conditioner units are measured by the ton, which is the cooling power of a single ton of melting ice over a 24-hour time period.

If you have a unit that is too large for the area you will notice that it becomes much too cold or much too hot while the unit is in operation.Choosing a unit that is much too small will mean that the unit is overworked as well as the amount of energy used is much higher.

Anytime a replacement is made you want to ensure that you either get the exact same type of unit that was compatible with the other components or other components to match the manufacturer’s specification of the new unit.

This is very important. Remembering this will ensure that you get the maximum efficiency from your new heating and cooling system possible.


Repairs are seen all too often when dealing with heating and cooling systems. One of the most common problems we see in air conditioning scenarios is that the condenser has either frozen or ceased working. Most units use freon to cool the air in the condenser.

The most common type of repair that most technicians see when going out to a job is that the power is not reaching the unit and allowing it to perform properly. When there is an interruption in the power supply the unit will generally not turn on or display the temperature on the inside thermostat.

However, if your thermostat operates by battery power the thermostat may still display the inside temperature while the unit refuses to work.

Different Types of Heating and Cooling Units

The most common type of heating and cooling unit today is the central heating air system. There are also internal blower systems that may help on efficiency if you do not want to engage in the burden of ductwork and other external components.

Another common type of heating system we see more commonly is called radiant heat. This type of heat operates on the flooring and the walls and comes from the surface of the inside of the home. These are becoming more and more popular within modern-style homes.


No matter what type of heating or cooling system you have the assessment of potential damage and efficiency problems is the key to making the best decision on whether you should replace or repair your existing system. This can be done by you or a professional heating and cooling company. Good luck!
