Why Does the Size of Your Air Conditioner Matter?

Considering the size of an air conditioner before installation is a smart practice that will help save you money and maintain efficiency. Many people are under the misconception that bigger AC units lead to better performance, but that is not always the case. There are a variety of factors that come into play when choosing the size of your air conditioner that can affect performance quality, efficiency and cost. This is why it is best to consult an HVAC expert before purchasing and installing an AC unit into your home.
Sizing Factors
HVAC experts look at these factors to determine the correct size of your air conditioner:
- The total volume of your home or living space
- The windows - How many do you have? What condition are they in? What orientation are they facing?
- The sun-exposed areas in your house
- The ventilation and ductwork within your home
- The shade provided by buildings or trees outside
- The size of the air conditioner in TONS
- The SEER rating of an air conditioner
Without keeping the above factors in mind, homeowners may become at risk of installing an oversized or undersized air conditioner unit.
Oversized Air Conditioners
Installing an AC unit that is too big for your home can lead to increased costs and reduced indoor air quality. Oversized air conditioners are at risk of cooling too quickly and shutting off before it has the chance to dehumidify your house and filter the air. Due to this, common pollutants, such as dust, mold, pet dander, and allergens will not be filtered through. Because the air remains humid and unfiltered during the first cycle, oversized air conditioners will frequently start up and shut down again. Ultimately, oversized air conditioners are known to run far too often for short periods of time, which can lead to increased costs and eventually lead to the wear and tear of your air conditioner.
Undersized Air Conditioners
Installing an air conditioner that is too small for your home can also be problematic. Undersized air conditioners work harder to cool a house that is far too big for it. While your air conditioner is running constantly, it is physically unable to effectively cool your home. This can lead to wasted energy and time that will eventually lead to costing you more in the end.
Ultimately, it is important to invest in a proper-sized air conditioner that best suits your home in order to reduce costs, maintain indoor air quality and efficiency.

On coldest night of the year our furnace quit. At 8:40 in the morning Greg arrived and gave us a diagnosis and a recommendation. By 2:30 we had a new furnace and were warm again. Great company. Great customer service. Good reasonable price.

Twin tech team was very efficient and prompt. They provided a quote within hours of request and got the job done on time. No disruption to home function. We would highly recommend this team. Job well done.
Our furnace bit the dust, and Twintech came out to troubleshoot and diagnose the problem within a couple of hours. Mitch was super helpful, patient, and answered all of our questions. When we decided to get the furnace replaced, the crew was over first thing the next morning and did a fantastic job. Not only did they complete the job in a few hours, but they cleaned up and respected our house as they went, and answered all of our follow-up questions. I've used Twintech for our HVAC needs in the past and will continue to do so. I'd recommend them to anyone, and it feels good to support a local, family-owned business.
Dave and the Twintech team were fabulous from day 1 and helped us through the process to identifying a new furnace and AC unit. This was our first time through this process and Dave did a thorough job explaining all the components and was very patience answering all our questions. Dave provided great insights and fair pricing.
The Twintech team did an awesome installation. Very clean and efficient. I would highly recommended their service.
We had a new Amana furnace installed by Twintech and we were very pleased with the installation. It is nice to have a warm house again.
Excellent job. Excellent service. Competitive price. Its rare to find a company with the knowledge and professional results we have experienced with Twintech. The clean and neat installation with attention to detail and drop sheers to respect our property is a clear indication of Twintechs high level of integrity. The 1-1/2 gas line upgrade they did for our pool 3 years ago was awesome. Can't say enough. Thank-you Twintech.
Twitch did a great job with the installation of our new furnace. I really appreciated their honesty and I could trust what they were telling me. Another company tried to suggest significantly more work at a greater cost claiming it was necessary to meet current building code. Twintech is very fair. All staff I meet were friendly, polite and trustworthy. I would recommend Twitch for a furnace.
This is a professional team that's easy to deal with. I would strongly recommend them
Very professional firm from start to finish!
They removed the old oil tank and furnace. They installed air conditioning and a new propane furnace.
Professional installation, on time and no mess.
Very pleased with their work and would highly recommend the company. Our house is three stories so they spent the time to do all the calculations to make sure we would have great performance on each floor.
Thank you again!
Upon a routine yearly maintenance, it was discovered there was a leak in the heat exchanger and a I needed a new furnace. I know nothing about these things and was completely stressed out. The company I had the maintenance plan with quoted me a huge number to rent a furnace, I just wanted to cry. Then I spoke to Dave at Twintech. He was so knowledgeable and calming, provided me a fair quote and within a few days I had an amazing crew show up to my house and install my new energy efficient furnace! I have already recommended these wonderful people at Twintech to a good friend of mine. Thank you Twintech!!

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.
Right on time. Explained how to work the HRV in a different way so the house would not be so dry. Changed my whole house water filter for me as well. Friendly, helpful, caring service!
Very pleased with the professional service that TwinTech Heating and Cooling provided in replacing my furnace. I got several quotes from different service providers. Their price was excellent and they explained the features very well. We are very glad we went with TwinTech and highly recommend their services.
We were new homeowners in need of a second opinion. TwinTech Heating & Cooling were Amazing and professional. Very knowledgeable and great service all around. Recommend to anyone looking for honest and reliable services. Treated with respect and care. Thank you Greg, Mitch and Bob!
TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all! I did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!
