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

Installing weather stripping or upgrading to insulated panels can improve efficiency.

Some types of electric fireplaces use more electricity than others. Models that produce 1,500 watts will have more of an effect on your heating bill than 750-watt models. 

Electric fireplaces use an average of $1.85 of electricity every eight hours. These minimal operational costs aren’t likely to make a big difference in your electric bill—unless you’re using it as a primary heating source for your home and it’s running most of the time.

Dehumidifiers typically use 300 to 700 watts of electricity per hour, whereas portable dehumidifiers use about 40 watts per hour. The exact amount of electricity your dehumidifier will generate depends on its capacity and energy efficiency. Generally, higher-capacity dehumidifiers generate more electricity than lower-capacity units, but they also usually have better energy efficiency over the long run.

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.

Insulation is measured by R-value, which is the measure of a material's ability to resist heat transfer. The higher the number, the better the insulation. When installing insulation yourself, you need to determine the optimal R-value you need to keep your home warm in the wintertime, cool in the heat of summer, and energy-efficient all year long. Each inch of insulation provides between a 3 and an 8 R-value. The climate where you live plays a major role in what R-value you need and the price tag you might see in your insulation installation.
