Central air conditioning systems started to become common for residential buildings in the 1970s. But many homes in the Durham area still rely on window units to provide their summer cooling. We recommend you have these window units replaced, either with a standard central air conditioning system (if you have ductwork in the house for it) or a ductless mini split system (a flexible option that makes it easy to transition away from window units).

To create lower temperatures indoors, your air conditioner uses the circulation of refrigerant, a chemical compound that can easily change between liquid and gaseous forms. As the refrigerant evaporates in the indoor coil of the AC, it absorbs heat and makes the air cooler. Then the refrigerant condenses in the outdoor coil, which releases the heat to the outside. This process is called heat exchange, moving heating from one place to another.
The beginning of the spring is the time to make sure the sump pump in your house is ready to do its job in case of flooding. Spring rains, snowmelt, and more water saturated into the ground bring the danger of water seeping—or flooding—into your basement. The entire purpose of the sump pump is to get that water out of there as fast as possible. Just like a generator, a sump pump is a device you hope you never need to use—but you want to ensure it will work in case ever need to use it. 
When you look at your monthly bills and see how much water your household has been using, do you feel a bit faint, or do you start seeing red? How can we be using this much water? you may be thinking.
Energy efficiency is a major concern homeowners have when they are shopping for new appliances. Because furnaces are vital for home comfort and consume large amounts of energy during the winter, their efficiency ratings are important to consider when the time comes for a new system installation.
Once upon a time, homeowners had few choices when it came to new water heater installations. Everyone used storage tank water heaters, and that was that.
With the weather so hot at summer’s end, everything is in danger of possibly overheating—including your air conditioner. Air conditioning systems are designed to operate in hot weather. Otherwise, they wouldn’t be much use to anyone. But the extra load of work, combined with all the strain and wear the AC has accumulated already during May, June, and July, can cause the motors or other components to overheat.
You probably aren’t aware of this, but a large part of the plumbing for your house is located down in the concrete foundation slab. It’s an easy way to pipe water into the house, and it keeps the pipes out of the way. But it doesn’t necessarily keep them out of the way of harm. If your home has hot and cold water pipes down in its foundation, the house is at risk of slab leaks at some point. And slab leaks are costly, wasteful, and can even create health troubles due to mold growth. 
You’ve got something wrong with the sewer line for your home. Maybe multiple drains are blocked or bad smells are wafting from sinks around the house. The sewer line probably needs to be cleaned out to restore your home’s drainage system. Here are the tools you’ll need to clean the sewer line: 
The sump pump is one of the most useful plumbing appliances for a home. It’s also an appliance that homeowners hope they don’t actually have to use often, since it’s there in cases of emergencies when water floods down into the basement or the crawlspace or when excess moisture builds up. Sump pumps are helpful during the stormy season, but they’re invaluable all around the year for when a major plumbing leak strikes and sends water cascading down into the basement of a house. The pump turns on automatically and starts removing the excess water—
