“Bell Brothers Plumbing Heating and Air was founding in 1991 in Elk Grove, CA by brothers Kenny & Jerry Bell. After almost 30 years in the business, Bell Brothers has expanded to not only specialize in heating and air services, but windows installation, plumbing, sewer, duct work replacement and insulation. With more than $5,000,000 in Home Energy Upgrade rebates earned for their customers, Bell Brothers has established themselves a leader in California’s Home Energy Upgrade Program for utility companies SMUD and PG&E. Today there are over 160 trucks on the road and over 200 employees daily serving the greater Sacramento area and parts of seven surrounding counties. It comes to no surprise that Bell Brothers delivers 365 Days of Satisfaction to all their customers by providing the highest install standards, the best trained technicians and year-round service. Bell Brothers guarantees that you’ll love your service or your money back, that’s what makes them the “No Surprise Guys!”
"UPDATE 4/25/2023 4 yrs after installation of a system that Bell Brothers designed and installed, my energy bills are higher than they were with the 20 yr old system it replaced. We have fewer people in the home, and it is supposed to be a high efficiency system. After numerous complaints, inspections, and supposed repairs to solve the problem, Bell Brothers told me that I need to turn off my high-tech, automatic thermostats and operate them manually as needed. Oh, and NEVER turn on more than 2 of my 3 zones at any one time. So much for the NO SURPRISE GUYS. UPDATE 3/18/23 AFTER CONTACT WITH BELL BROS We have been contacted by Bell Bros since this review with an offer to replace the plenum and reprogram the zone board. We requested a written explanation of those repairs, and how they would solve the problem. We have not received that information. UPDATE 9/19/22 - AFTER TRUE-UP My energy usage (and annual bill) is higher after replacing a 20+ year-old system with one that is supposed to be more efficient. That makes no sense. We have fewer people in the house, and have had more than our share of power outages and flex alerts. This is definitely a very expensive purchase that we thoroughly regret. UPDATE 9/8/21 - AFTER 3 DAYS OF HEAT WAVE We typically open doors and windows or run the whole house fan to take advantage of the cooler morning temperatures. Since the insulation was upgraded, the temperature inside the house seems to be holding between 10-15 degrees cooler than outside. At this point, we are comfortable and looking forward to see if our heating/cooling bills are lower at true-up. UPDATE TO ADD ACTIONS TAKEN BY BELL BROS SINCE MY REVIEW Approximately 1 week after this review was posted, I received a message from Bell Bros Sales Manager wanting to discuss my insulation options. When I returned his call and gave him the details of my experience with his company, he apologized and offered to insulate my home at no cost. Needless to say, that was a more than fair offer and I accepted. In spite of some unprofessional communication issues, the work was performed yesterday and we are waiting to see whether it makes a difference in our comfort and/or our hvac bills. I am raising the rating to 2 stars now, and will be updating the rating further if we see some positive changes in how our system works. ORIGINAL REVIEW Installed complete HVAC system to replace 20 year old system in 4000 sq ft house. Represented that new system would operate more efficiently and should decrease my heating/cooling costs significantly. Prior to installation, they inspected my entire system, including insulation and ductwork and made recommendations for the best system for my needs. I asked about insulation at the time of the install and was told it didn't need to be installed. Two years later, my bills are HIGHER, and now they tell me I only have 6" of insulation when I should have 16". Temperatures in my house are consistently higher than the selected temperature. I have one room which takes more than an hour before the air begins to blow. They tell me it is because this room is so far from the unit. They are the ones who decided where to place the unit. Very unhappy with the difference between what they told me I needed, and what I actually got. Services: Install thermostat, A/C system maintenance, Heating system installation, HVAC duct & vent installation, HVAC system maintenance"

I am a provider of comprehensive energy audits, data driven analysis of your home and recommendations for cost effective energy efficiency improvements. I use a blower door, duct leak tester and energy modeling software to figure out how you can save money on energy bills. Also, I don't sell windows or HVAC services, so you can trust that my recommendations aren't motivated by self interest.

https://personalpowerproject.com/ Personal Power Project - Solar Panel Installation Business. We install solar panels, and our specialty is helping people to reduce all of their energy bills to ZERO per year, when the average in CA is approaching $10,000 per year. For most people their electric bill is only one third of their total energy expense. Natural gas or propane gas for your home and gas for your cars amount to the other two thirds. This takes long range planning and that is what we do. If you need an emergency repair or service ASAP, we do that too although it's not our main focus so probably faster to get another company for emergency jobs. Our business model is to help you go 100% off grid while still being connected, if and when you need it. It's easy to be 100% off grid if you are not 100% electric. Being 100% off grid and 100% electric, on everything else is difficult and takes a lot of research, resources, planning, and some good advice and direction. Governments worldwide are mandating the all-electric movement so there is no avoiding it. It might take years for you to get there, which is not unusual and it's worth it, to eliminate $10,000 worth of energy bills per year which continue to climb higher each year. We dispatch our local solar contractors from our nationwide solar companies, of your choice, for all the help you need.

FAQs for energy efficiency auditing projects in Elk Grove, CA
An energy audit costs about $420 on average, ranging from $100 to $2,250, depending on the size of your home, property, location, and the tests the auditor needs to perform. Keep in mind that the 2022 Inflation Reduction Act’s Energy Efficient Home Improvement credit covers up to $150 of home energy audit costs. Common energy audit tests include:
Blower door test: $350
Duct testing: $100
HERS test: $375
HERS certification: $200
Infrared imaging: $200
To find a reputable energy auditor, find a local company that offers energy audit services. Research the company’s reviews, methods, and certifications to find a reliable professional in your area. The most reputable energy audit companies are HEP-certified by the Building Performance Institute (BPI). Be sure to check our state licensing tool to review the local energy auditor guidelines to ensure you’re hiring a certified professional.
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.
Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.
The three levels of home energy audits include:
Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.
Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.
Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.
