Without a doubt, HVAC units are an important part of houses and all professional settings. An HVAC system is designed to control all the different conditions of the environment inside a building space. The main purpose is to create an environment that is comfortable for everybody. However, when the equipment shuts down, it becomes difficult to achieve it. This is when you need the help of HVAC contractors to figure out what could the root cause be for the failure.

When you are buying HVAC units or assessing the quality of an existing unit, the energy efficiency is the very first thing to look at. This does not only apply to HVAC systems, but to a wide range of other equipment too.

There is no doubt that HVAC units are one of the primary contributors to the household electricity and energy bill. So, even small changes in the efficiency of the HVAC unit could show up as a big impact in your electricity bills.

What makes an HVAC unit efficient?

The energy efficiency of an HVAC unit depends on a certain number of factors. First of all, it is goo for you to understand the science behind HVAC units. Furthermore, you must know about certain ratings that the scientific community uses. So, let us look at some of them now.

First of all, you should know about the SEER (season energy efficiency ratio). This is an energy efficiency rating that is very commonly used in the US. This rating is mainly measured in terms of British thermal units.

Other than this, we also have the EER, which simply stands for Energy Efficiency Ratio. This is the rating that is applied to most of the residential HVAC units. So, the efficiency of an HVAC unit depends on these ratings.

Make sure that you know about these ratings when you are going out to buy a new unit.

Making your existing HVAC unit highly efficient?

In order to make your existing unit efficient, you must carry out certain steps. Of course, there are many ways to achieve that. First of all, you must improve the quality of insulation that your room has. If the insulation in your room is bad, this means that the warmth from your room will readily escape outside. When this happens, your HVAC unit will be working harder to compensate for the losses. And this will show up as an increase in your electricity bills.

At the same time, you must also minimize the leakage in the duct by using an aeroseal duct sealing. This is one of the most effective methods, and is used by many HVAC repair and maintenance experts. This method significantly enhances the efficiency of your existing HVAC unit.

Lastly, if nothing seems to be working for your HVAC unit, then chances are that you will have to get a new unit altogether. A newer unit will of course, work better and will deliver you a higher performance. So, do not hesitate to buy a new unit when the time is right.


Now, we hope that you know everything about achieving a high efficiency with your HVAC unit. It is certainly not an easy thing but it is rather straight forward. However, layman are bound to have difficult deciding the best course of action.

This is why we suggest you take help from HVAC repair and maintenance experts rather than trying to sort it out on your own. This is the best way to achieve a high energy efficiency. So, what are you waiting for? Reach out to air conditioning companies McLean today and get it sorted!
