Should I Turn the Central AC On or Off While on Vacation?

With the summer announcing its arrival, homeowners are starting to leave their homes to be on exciting vacations doing all sorts of fun activities.


But before you get to carried away, make sure that you have a plan as to how you will manage certain systems in your home while you’re out of the house. In this post, we’d like to address your question of whether or not you should turn your central AC while you are away.


There are a few factors that you have to consider, including how long your vacation will be. But before anything else, we’d like you to make this consideration:


If your primary concern is saving energy, turning the system off will deliver you that result. So, why is it that turning the thermostat up while you’re away the more recommended option?


Length of Vacation


If you’re going to be away for just a short time, like a day or two, it’s better to have your air conditioner running but set it at a higher temperature than what you usually do.


Cooling your empty house to the temperature level you’re comfortable with when you’re at home is wasteful and really unnecessary. Your central AC unit might be overworked if you expect it to keep a hot house at a more comfortable temperature, but you will also get to save energy as well as keep the humidity level under control when you leave it on.


A programmable thermostat comes in really handy in this kind of situation. This small device lets you set your desired temperature at varying times. That means it kicks on and off on its own automatically. Just set the thermostat between 7 to 10 degrees higher than you normally would.


Remember to close the curtains before you go to block the afternoon sun and help keep your home a little bit cooler.


If you’re going to have a longer vacation and no one will be home for a week or more, you can definitely save the most energy and cost by keeping your cooling system off. You can simply set your programmable thermostat to start cooling your house a day before you get back.


Other Factors You Need to Consider


Aside from the length of your vacation, other factors that can help determine whether it’s wise to turn your AC on or not include:


  • Weather
  • Efficiency
  • Protection of Other Parts of Your Home

by Scott and Sandra in Ajax on Twintech Heating and Cooling

After receiving numerous quotes to replace my old furnace and AC unit (which was 20 years old) I went with Twintech. Dave, in sales, answered questions professionally and promptly and worked diligently in order to secure my business. Installation was scheduled the week after and Greg and Peter showed up, as scheduled, and did a fine job installing both units. The site was left tidy and neat. I would highly recommend Twintech for your furnace and AC work.

by Linda from Whitby on Twintech Heating and Cooling

I chose TwinTech because they installed my new furnace a few years ago and did a great job. When they installed my new A/C, they replaced all parts -- the copper pipes, the housing on top of the furnace and the wiring. (Apparently, the wiring for my old A/C was insufficient.) Their pricing was competitive. The sales representative came to see me within a few hours of my call. My new A/C was installed a few days later and I couldn't be happier with Twintech's professionalism and work. I would recommend TwinTech to any homeowner.

Had a great experience with this company. Great price and great customer service. You wont be disappointed with twintech. Discussed the job with Greg while he was installing who was extremely informative and obviously enjoys the work he does.

by Nuzio in Markham on Twintech Heating and Cooling

I needed my AC unit relocated due to upcoming landscape work. I reached out to the Twintech team through Homestars. Dave connected with me immediately to discuss the project and various options. We decided the best option was to mount the unit on the wall. Greg was in touch with me the same day as well and we scheduled the work for later that same week. This was a small job so I did not think I would get immediate attention. The Twintech team exceeded my expectations in every respect. They were very knowledgeable and friendly. The team arrived exactly on time on the scheduled day and worked efficiently to get the job done quickly. I would definitely use Twintech again for any Heating and AC projects.

I have used Greg Dainty for over 15 years in 3 different homes, for heating, cooling, pool heaters, appliances and bbq lines. Greg has always been so professional, friendly and the workmanship nothing short of fantastic. Greg has always discussed my options and fixing versus replacing, giving his honest opinion and what works best for me cost effective wise and long term. I have valued his opinion so much and have not trusted my gas needs with anyone since using him. I have also referred him to many of my friends and family and have always been so thankful with how well and quickly he looks after us all. I hold Greg in the highest regard and would recommend him to anyone with complete confidence!

by Marcel M, Whitby ON on Twintech Heating and Cooling

Really nice honest guys. It was a pleasure to do business with a company that does exactly what they say they’re going to do! My basement was cleaner after they installed my new furnace and AC. Thanks again Greg and Grant and for doing such a great job.

by George In Pickering on Twintech Heating and Cooling

5 star service!! I had twin tech install a high efficiency furnace and hot water tank at my home. I am taking time to write this review as a thanks for what I viewed as next level service that went above and beyond. Prior to installation they explained my specific options without pushy sales tactics and up front costs. Greg and Grant replaced a large portion of the duct work (built in their own shop) that had rusted over the years which resulted in a great looking job. It was a pleasure to work with people are passionate and take pride in their work. Following the installation they explained all aspects and maintenance of the new equipment. Products have worked flawlessly. Thanks again Greg and Grant! Highly recommend!!

by Donna J, in Ajax on Twintech Heating and Cooling

Twin Tech was great; they were honest, reliable and very thorough. I would recommend their services and will definitely be using them in the future.

by Sheila C. Pickering on Twintech Heating and Cooling

Hi Dave, Thank You Dave for coming to my aid this past summer when my AC quit. Your men did a great job installing and cleaning the area. The unit is working very well and i would highly recommend your company TwinTech. Dave you delivered what you sold and i truly appreciate it.

by Darin O. Whitby on Twintech Heating and Cooling

My experience with TWINTECH has been excellent, start to finish. While doing market research I made a list of several local companies and called them for some high-level information. Dave was the first to call me back, and the only one to book a meeting to see my place in order to give an informed, accurate estimate. He reviewed the different AC makes and models with me, explained the technology, and made a recommendation appropriate to my home. The installation went smoothly. I had one post-installation issue – there was moderate noise/vibrations coming from the duct system. I called about this, booked an appointment, and the technician resolved the issue during the service call. I feel assured having a 10-year warranty on parts & labour. I would recommend TWINTECH to anyone considering an AC or furnace for their home. Regards,
