The line set is an essential part of any split system air conditioner. A split system AC is probably the type you have: it’s the standard air conditioner set-up of an outdoor condenser cabinet where heat is released and an indoor unit and blower to remove heat from the air and then send it into the ductwork. The line set is the vital part the connects the indoor and outdoor components. It’s a double set of copper refrigerant lines that carry the circulating refrigerant to and from the units. The line set is sometimes exposed and sometimes hidden in the ground.
During an AC installation in Burlington, VT, the copper piping for the AC must be cut to fit the place of the unit, as well as match the specifications for the air conditioner. This requires professional precision, as does anything involved in air conditioning installation. And when it comes time to put in a new air conditioner, professionals need to make special considerations of the line set.
When your air conditioning system won’t turn on, you know it means trouble. After all, you’ll feel the effects right away and want something done about it. But what about the reverse problem, an air conditioning system that won’t stop running? You may enjoy the cool house for a bit, but when the AC won’t power down, you’ll not only have a house that’s too cold, you’ll also waste enormous amounts of money and have an air conditioner that’s wearing down so fast that it will need replacement years too early.
When you read our posts about regular air conditioning system maintenance, you’ll notice we often mention spring as the best time to have it done. Which it is. Spring maintenance preps the air conditioner right before the time when it does the most work, and it also lets you schedule a convenient time for the service when you won’t have to rely on the cooling system.
A central air conditioning system has two fans: one located in the outdoor condenser cabinet, and the other in the HVAC cabinet inside the house. These two fans are essential for the air conditioner to do its job. Obviously, an air conditioner that cannot send air out through the vents isn’t going to be much good to you! And if the outdoor fan fails, the air conditioner won’t be able to effectively move heat from the indoor air to release it outside.
The compressor is the most critical part of your central air conditioning system. All parts of an AC are important for it to operate, but the reason we say the compressor is the most critical is because when it fails, not only does the AC lose its ability to cool, it also usually means the air conditioner must be replaced with a new condenser and indoor evaporator coil.

This is a question we sometimes hear from customers who are looking to lower household costs. It makes sense for people to inquire about purchasing used AC equipment since so many other expenses for a home can be reduced by buying used. A car for example. Or furnishings. So why not buy a “previously owned” air conditioner, especially at times when people are looking closer at their budgets?
Spring arrived a few days earlier on the calendar this year. But that’s only the “official” first day of spring, a point in the Earth’s journey around the Sun. Our local weather doesn’t obey the calendar, and the cold weather blows through here sometimes until May. But spring is still the season of air conditioning tune-ups and inspections, no matter what the weather is like. Without fail, the summer heat will arrive, and you’ll want your air conditioning system in peak shape to handle it.
Fall has officially arrived and this is an important time of the year if you’re a 
Now here’s an unpleasant problem you may run into during the last days of summer: an air conditioning system that doesn’t work because the compressor has died. The compressor is the literal heart of a cooling system, since it’s the component that causes refrigerant to circulate through the system, turning a cool low-pressure liquid into a hot high-pressure gas. When a compressor is fried because of a burnt-out motor, an air conditioner turns into nothing more than a large fan.
