Indoor Comfort, Heatlh & Energy Efficiency Experts for your home. Barron is the areas leader in understanding how building science plays a major role in the comfort, health and overall efficiency of your home. This includes the home heating & cooling system, specifically how the home and duct system relate to the heating/cooling systems performance within the home.

"We hired Barron Heating because years ago they were a good company and did good work for us. This time however, I have to say they are the worst contractor we have hired in 45 years of home ownership. The salesman told us they could fit an upgraded furnace in our existing space. They were not able to fit it where they said they could, and it obstructed the laundry room doorway so badly that the washer and dryer would not fit through the doorway without removing the furnace again. For the next six months, they stalled, made excuses, and lied (in writing) about coming back to do the job properly. At that point, we hired a lawyer and notified them of our intent to sue for breach of contract, including failure to have the required state inspection performed. Only after being faced with the choice of going to court or fulfilling their contract did they take any tangible action to properly reinstall the furnace. Unless you don’t mind the possibility of 17 months plus the additional cost of a lawyer and process server to get a simple furnace installed and legally inspected, learn from our mistake - hire a different contractor."

Residential and business water treatment systems. Water softeners, UV lights. We will analyze your water for contaminants such as chlorine, low pH, iron, bacteria, and devise a system to suit your needs. Treat your water from the source, as it enters your home, so whether you are drinking it, cooking with it or bathing in it, your water is pure.

"The process was quick and easy. I just provided a water sample. It was determined that I had high levels of chlorine in our drinking water. I was able to solve my water problems with only one filter. Why did I wait years to have this done? Now I can be confident that our water is safe. Highly recommended."

Septic Tanks questions, answered by experts

While mound septic systems can provide cost-effective wastewater treatment in many instances, they do come at a significant initial installation cost and require a lot of space on your property for the mound and its replacement field. The installation cost is so high because this is a project that requires an exceptional level of skills and expertise to execute properly.

Septic tank lids may or may not be buried in a yard. Most lids are buried at least 4 inches deep unless you have an aerobic septic system. Aerobic septic systems need frequent cleanings, about every four months, so it’s best to leave these lids aboveground for easier access. For buried lids, homeowners can use risers that make it easier to locate and access a buried septic tank lid.

Certain foods are easier on your septic tank than others. Septic-safe foods include yogurt, fruit, cooked veggies, and bread because these items all break down relatively easily and can pass through your system safely. Rotten tomatoes, specifically, are actually good for your septic tank because they can increase the amount of good bacteria in the system. 

Most septic tanks can handle two to three loads of laundry per day, or a weekly total of between seven and 10 loads. Although septic systems do require homeowners to be somewhat careful with their plumbing systems—for instance, it’s not a good idea to flush a bunch of toilet paper all at once—they can still handle fairly heavy use.

The depth of a septic tank’s drain lines is between 18 and 36 inches underground. These pipes are filled with perforations and surrounded by sand, gravel, or a combination of both, as both materials help filter wastewater. While some pipes are buried closer to the surface, this can create problems unless the soil is compact and doesn’t shift much.
