Air Conditioning FAQs – Cooling, Saving Money & Pets

Trane Air Conditioning and heating productsAs a 20+-year company that handles air conditioning system repair, maintenance and installation, Custom Climate Concepts has probably “heard it all.” This is especially true when it comes to questions that clients ask us most often. Here we provide answers to some of those frequently asked questions.

Q. Does a larger air conditioning system work better for cooling?

A. Maybe it seems contrary to logic, but the answer to this question is ‘no’. A larger air conditioner will not cool (or heat) your home faster or better than one that’s measured to be the proper size for the air it needs to condition. In fact, a too-large system will operate in shorter cycles, causing more frequent starts and stops, resulting in a higher energy bill and higher humidity. On the other hand, if a system is too small, it will run continuously to try to get to the desired temperature, which also will ultimately raise the cost of energy. Overall, the best sized HVAC system for your home is based on your house’s square footage. Then it can heat and cool your home ‘just right.’

Q. Should I keep my air conditioning super cool for my pets when I’m not home?

A. If you’re going to be away for the day it’s recommended that you keep your air conditioning system running and set at 78-80 degrees. This is an appropriate temperature for most pets. Also be sure to leave your furry friends plenty of clean water so they don’t become dehydrated.

Q. What about setting the temperature higher when I’m on vacation?

A. It’s ok to turn your thermostat up a few degrees while you are away for a few days or longer. Here, the ‘sweet spot’ is to add four degrees to your normal setting. More than that can cost you too much when you come home and want to cool it back down to your desired temperature. Or worse, your house could become too humid and develop issues like mildew or mold.

Q. How can I save energy (and money) without investing in a new AC system?

A. One upgrade that surely makes a difference in energy savings is to install a programmable thermostat. When used properly, on a correctly sized air conditioner (see FAQ above), a programmable thermostat can reduce your heating costs by up to 35 percent and cooling costs by up to 25 percent, according to the US Department of Energy (

Sometimes an old air conditioner is a lost cost. Replacing a blower is fine but replacing the most expensive components can cost you more in the long run. When buying a new air conditioner make sure you get one sized appropriately for your home.
