Understanding HVAC Systems

Welcome to my blog! My name is Darren. My friends say that I am boring because I love the HVAC system in my home. I am not an HVAC professional, I just love the gentle hum of my air conditioning system as it gently brings the air in my home to the perfect temperature. When I was a kid, my family couldn't afford air conditioning so I spent many summers sweating away and feeling miserable. I vowed to myself then that when I grew up, I would have the best HVAC system money could buy. I hope you find my HVAC blog useful.

What You Should Look For When Buying a New Air Conditioner


When you're in the market for a new air conditioner, you may look for something energy efficient and whisper quiet. It's good to think about the energy used to cool your home, and a quiet air conditioner is a good choice for any house, but there are some features that many homeowners still overlook, and which can make a difference in how well the air conditioner works and in its overall operating costs. Note a few of those features here so you can get the best model for your home and are sure to be happy with it for years to come.

Name brand

One reason to choose a nationally known brand of air conditioner is that it may have a longer warranty, and one that covers more parts. Manufacturers of name brands may put more time and research into creating a reliable system, so they are more likely to stand behind their products with long, inclusive warranties.

Another reason to choose a name brand is that their replacement parts may be more easy to find, and more affordable. When a part in your air conditioning system breaks and you need it replaced, you don't want to hear that it's no longer manufactured! Name brand appliances of all types usually are easier to repair and have cheaper parts that are easier to source, something to consider when it comes to long-term ownership of the air conditioner itself.

Shade and insulation of home

When sizing an air conditioner, you may go by charts online that tell you the best size of unit for the size of your home. However, an older home with poor insulation will usually allow in hot air from outside. On the other hand, large shade trees on your property that hang over your home can make the house more cool and comfortable. Get a more powerful unit for a home with poor insulation, but downsize the unit if your home is well shaded, well insulated, and typically very cool during the summer months.

Dual compressors

If you've never heard of dual compressors, these allow for more power when the temperature is at its highest and the air conditioner needs to work hard to provide cool air in the home. When the temperature drops somewhat, only one compressor may switch on to provide some cooling to the home's interior; this can mean less wear and tear on the unit and less use of electricity. For homes in areas with extremes in temperature or for larger homes where both compressors may be needed to provide adequate cooling, this can be the best choice.
