home air conditioningWindows are my least favorite energy upgrade because of their short life span. The average window only lasts 7-10 years and that’s only if it is installed correctly. First off, you should never buy a window that does not have an ENERGYSTAR logo on it. If it has the logo, that means that the R-value is at least R-2.3 (this is actually good for a window), it has argon gas between the glass, it has a low E coating to reflect UV in the summer, and it has a UL rating of .35. All of these are minimums, but make a good window.

Generally speaking there are three main local hvac components of an air conditioning system. In order to begin your air conditioner training you need to know exactly how each of these systems works and what are some early symptoms of failure in these components.

The Atlantic Ocean: This might seem like a given but let me explain. The ocean off York County does some interesting things that oceans in other parts of the country or world don’t necessarily do. In the summer, the ocean off the coast of York County, Maine never really warms up too much. While this isn’t conducive to swimming, it does act as an air conditioner on those oppressively hot days. Much of the time, a sea breeze develops in the afternoon and provides coastal residents with a cooling effect while inland communities continue to roast. That combined with the sweet, fresh smell of the sea air can make for a euphoric experience.

If you do multiple air sealing and insulation projects to your home, you may find that the air is stagnant and new odors may develop. This is a sign of lack of fresh air moving through the house. It is a good idea to have an Air Recovery Ventilator installed or ARV. An ARV brings fresh air from outside and distributes it into your home through it’s own duct work or your hvac in my area duct work. At the same time it displaces any overly moist or stagnant air and exhausts it outside. This item must be professionally installed and costs between $500 and $2,500 depending on the size and complexity of the unit. When I say complexity, I am talking about heat exchangers and cooling cools, things of that nature.

In between these visits, there are a few things you can do to maintain it. For best results, do this on a cool day well before the hot weather arrives. It will give you a chance to assess things and call in a professional if necessary. The first thing you should do (after turning off the power at the service panel) is to check the outside condensing unit. Make sure it is not covered or blocked with grass, shrubs, lawn furniture, or any other debris. The system needs plenty of space-at least four to five feet-in order to be able to draw air into it.
