"We will never use this company again. They were not upfront on their labor charge for a part under warranty and then threatened us to send us to collections when we asked to meet them half way. They also tried selling us an air scrubber yet neglected to tell us the reason we are having a mold issue is because the seal between the house and the unit has holes in it. They also did not put back things moved to get to the unit and crawl space. It is unfortunate that there are companies out there who choose to do business in this manor."

Freedom Dog Fence is an electronic dog fencing system that is installed underground by burying a single wire as a complete loop along the entire perimeter of your property. This underground boundary can also include or exclude certain portions of your yard, such as a pool or garden. Your dog is safely contained within your yard and allowed to roam free with sections of your yard blocked to keep your garden and landscaping safe. Your dog can even be trained to stay out of your pool! Dogs live to run free, and keeping your dog safe in your yard gives you both the freedom to relax when you are outside.

"Excellent repair job with absolutely no complaints. This review is after posting a 3 star review a few days ago for not returning my phone calls. I was contacted on Monday and given an apology with explanation that the company had been short staffed and had tried to contact me earlier, apparently the call going to my Spam box. On 12-14-22, Tyler arrived at 11 AM and immediately went to work to locate the trouble with my underground dog fence. Apparently several breaks were located and repaired, about a 2 hour job. Tyler was very professional and apologetic for not getting out sooner and reduced my service bill by 50% for any inconvenience experienced. I tried to remove the earlier comments posted a few days back but was unsuccessful, thus this new review. Outstanding and pleased with the repair."

Energy Efficiency Auditing questions, answered by experts

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.

A couple of the best ways to find a reputable energy auditor is by determining whether they are HEP-certified by the Building Performance Institute (BPI). This certification will help you narrow down your list of professionals to the most qualified pros with the most relevant experience. 

You can also choose from the Department of Energy’s certified list of energy auditors or Angi’s contractor licensing tool to find pros in your area.

Leaving vents open but closing doors in unused rooms will probably not save money on your energy bill. Closed doors prevent the natural flow of air throughout the home, which could reduce the efficiency of the overall HVAC system. They could also restrict airflow into and through the return vents, making the HVAC system less efficient.

Energy-efficient windows are judged on their performance according to a few different factors, including heat transfer, air leakage, light transference, and condensation resistance. If you're unsure whether a window is energy-efficient, look for an ENERGY STAR® label from the U.S. Environmental Protection Agency (EPA). If various products, including windows, meet energy-efficiency standards set by the federal government, the EPA issues this label to help consumers identify energy-efficient products.

An average, 400-square-foot electric heated driveways consume approximately $3 per hour in terms of electricity. The price may slightly fluctuate depending on your local energy cost. A simple formula to calculate your heated driveway’s total wattage consumption is by multiplying the square footage by 50 watts and then dividing it by 1,000 to get the kilowatt number. Multiply that with your local energy cost per hour and there you have the hourly operating cost.
