"Excellent customer service from the first time Joe contacted me to the time Mike and his crew came to install new furnace and a/c units. One Hour Heating and Cooling was very affordable and was the only company I had to come out to give an estimate to identify an hazard with a pipe leading to the drain and the resolved it. Thanks to Joe and Mike educating me on the furnace and a/c units, they answered every question or concerns I had. I had 3 other companies to come out and was trying to replace items that didn't even need to be replaced. They were trying to justify their enormous prices and because of One Hour Heating and Cooling I didn't fall for it. I would truly recommend this company to anyone who is in the market for heating and cooling services. One Hour Heating and Cooling is truly about their customer's need and provide the best value."

Hi, I’m Mrs. Michael, and when you need something repaired, We wanna be your guy. Back when I was raising two babies, my husband and I started a plumbing company, an electrical company, AND a heating and air company. Mr. Michael is a genius with tools, but he did NOT enjoy running 3 big companies, so he asked me to do it. Turns out, I LOVE it!! I believe that if we make your problems disappear quick and easy, then when someone you know needs something repaired you’ll say: “I’ve got a guy! . . . Her name is Mrs. Michael.”

"I called Mrs.Michael plumbing and electrician on a Sunday and was told the service call would cost $129. However, I wasn?t informed that the $129 only covered the technician?s arrival. Once on-site, I was told diagnosing the issue would be an additional $450 ? and that price only covered two outlets, with anything else costing extra. I?ve rented homes for over 30 years, and I?ve never encountered such misleading pricing practices."

Energy Efficiency Auditing questions, answered by experts

The difference between an energy auditor and a home inspector is primarily in the purpose of the inspection. The energy auditor conducts tests in your home to determine the energy efficiency levels in areas like windows, insulation, and doorways. The auditor then makes recommendations for ways to improve a home’s energy efficiency. 

A home inspector examines various structures of your home to determine that everything is up to code and gauge the condition of features like the roof, foundation, HVAC, and electrical. The home inspector reports on the overall home and makes repair recommendations.

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.

When combined with a substantial solar system, if you have enough Powerwalls, you could go off-grid and be energy independent. But remember, you'd need enough Powerwalls to power your whole home continuously because a single Powerwall can’t power large appliances for extended periods. One Powerwall is able to power an average-sized home's emergency circuits, lights, and outlets. To power large appliances, you likely need two or three Powerwalls.

Leaving lights on raises the electric bill, but not as much as having high-wattage light bulbs. The best way to save on electric costs is to swap your light bulbs to LED or CFL bulbs that use far fewer watts. You can also use smart lights and light switches to control usage via a smartphone or voice-controlled device.

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.
