  1. Hey there! This is my 1st comment here so I just wanted to give a quick shout out and tell you I genuinely enjoy reading your posts.

  3. A central air conditioner relies on ducting and registers (openings) to carry cool air all over your home. Essentially, the system pulls air in from outside, cools it, and then pushes it throughout the house via the ductwork.

  4. A clogged or dirty air filter can cause your unit to run less efficiently, thereby impacting your overall level of comfort and driving up energy costs. Change the filter once per month during the hot season and every two or three when your unit is only used some of the time.

  5. Nice blog. My AC is not cooling the house properly as I think it should. We just moved in a house where the AC unit is located on the side of the house and the unit that it is connected too is located in the basement. I had a friend look at it, and he said that the HVAC unit in the basement is leaking air when the AC is on. Since the HVAC unit is located in the basement than all the vents are under the floor on the main floor. I’m not sure what I need to replace or do to cool down the house. Thanks

  6. These are some great questions, particularly the one about investing in a programmable thermostat. After all, there are many homeowners who do not know that this kind of thermostat can actually help with their central air conditioning. By being able to program when the AC comes on and off you can make sure that your HVAC system is as efficient as possible.
