"Repair Service to Fix Gas Boiler - WM Henderson first sends out a tech who is not familiar with gas boilers and admits there is an issue but does not know how to diagnose it. I had to pay $89 for this. Instead of having the right person come out, I had to to actively call again to get someone else to come out. The 2nd tech diagnosed the issue, but wants to charge me the same $89 that I already paid. - and quotes me $380 for the repair - and has to order the part. I agree and then call back the next day to confirm part is on order - and they tell me the charge is $1,015. I asked to speak to a manager to discuss, and no one is available and no one calls me back. I bought the replacement part from a supply where house (confirming it works with my make/model of boiler) and it cost me $165. I have had other scheduling issues with them as well. Don't use them!!!!!!!!"

We can help pinpoint areas of the home that can cause high bills, poor comfort and leads to dirty and sick homes. Two Rivers has over 50 combined years of experience in home energy auditing and installation of multiple measures to make a home more comfortable, while lowering electric bills and making your home healthier. Including removal of old and dirty poor performing insulation and adding both new fiberglass or spray foam insulation. We also specialize in sealing homes to reduce air leakage, and reduce dust, pollen, airborne particulates and keeping insects out. We can also ensure that your HVAC duct system is sealed properly so that the money you pay to heat and cool your home goes into the living space of your home and not the attic. Two Rivers is a small family run business, we treat all our customers like family and treat your home like it was one of our own.

"Went very well. Getting the estimate was quick and easy. And, the work was done on time and efficiently, took approximately 1 1/2 hours. Then they cleaned up the small area beneath the ladder that needed it."

"I would use this company again and again. They were responsive, punctual, and SO respectful of our home! One of our AC units was dying but limping along, and they came out and gave me a realistic idea of what it would take to fix it and what that might mean overall. We opted to replace it. They gave us a great deal and were patient and worked with us as my husband was in the hospital with a serious medical condition and I was scattered as I tried to schedule the work."

Energy Efficiency Auditing questions, answered by experts

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

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.

Smart home upgrades can be worth the money. Several upgrades, including smart thermostats and ceiling fans, can help reduce your energy bills. Others make life more convenient, freeing up your time to do what you love (or get more work done). And some smart home upgrades, such as entertainment systems, simply make life more enjoyable. All are worthy causes.

There are several indications of an overloaded electrical panel, such as frequent circuit breaker tripping, burn marks, or flickering or dimming lights.

If you’re observing any warning signs, turn the circuit breaker off, then shift some devices from the overloaded circuit to a different one. If there are still signs of overload after turning the circuit break back on, contact a professional electrician to help you fix the issue.

Upgrade to double-glazed glass or apply energy-efficient coatings to reduce heat loss and utility costs.
