Smart thermostats don’t use batteries either because their displays require more power than a battery can provide.

Gas vs Electric Furnaces

December 19, 2019

No furnace, no matter how well built, lasts forever. A gas furnace may work well for 20 years and an electric one for 30, but the time comes when the model requires replacing. And this brings up another point: There are significant differences between gas and electric furnaces. Knowing about these differences could make it easier to choose the right one at replacement time. Little Things Aren’t Little When looking over gas and electric furnaces, don’t assume any subtle difference is no big deal. A gas furnace tends to be a little on the noisy side. An electric model, however, runs much quieter. While these two differences won’t likely make or break a buyer’s decision, they do drive home the point that differences exist. A Serious Concern About Safety Be sure any furnace in your home is well-maintained to enhance safety. An electric furnace, admittedly, comes with fewer safety concerns since it doesn’t emit carbon monoxide nor ignite gas. Still, it doesn’t hurt to have safety inspections performed, whether gas-powered or not. provides heating system maintenance and repair work. Our team also installs furnaces if requested.

3 Tips to Avoid Costly Winter Plumbing Leaks

November 8, 2019

Dealing with plumbing problems can be a hassle. What homeowner wants to see a leak dripping onto the carpet or floorboards? At least minor problems aren’t catastrophic. Winter-weather plumbing troubles, however, can be disasters in the home. Don’t let leaks create severe damage this winter. Take some preventive steps to keep them from happening. Don’t Let the Interior Pipes Freeze At best, a frozen pipe might crack and spring a small amount of pressurized water. Unfortunately, a burst pipe usually leads to a massive hole — or holes — that pump out an enormous amount of water. Entire basements can fill up with water within a short period. A lot of damage can occur before turning off the valves. If the shutoff valves are damaged, the end result could be tens of thousands of dollars in damage. Preventive maintenance is critical to avoid burst pipes. Make sure the temperature inside the home doesn’t drop below freezing. That means you should service your furnace and keep it in good shape. Insulating the pipes is also a smart plan. Pipe “blankets” can help with this. Inspect the Plumbing in Advance Leaks sometimes result from small problems that grow and worsen over time....

September 15, 2019

Dealing With a Faulty Thermostat If you’ve noticed that the thermostat in your home isn’t reading the right temperature some of the time, there are several potential culprits to the problem. Checking a few key things can rule out some of the most common issues and let you determine if your unit is actually broken. It’s important to have a functional thermostat so that you can keep your home at a comfortable temperature throughout the year. The first things to do are the following: 1. Check the Location of Your Thermostat Your thermostat should be in a central location in your home. It shouldn’t be in direct sunlight or in the path of any drafts in your home. Make sure that it’s located away from any heat sources that could skew the reading. A properly mounted thermostat should be mounted about 5 feet above the floor to get the most accurate reading. 2. Make Sure It’s Level If you have an older mercury thermostat, make sure that it’s level so that it can read the proper temperature. Sometimes your unit might have been installed improperly, or it might have gotten knocked out of alignment. The more level the mercury bead...
