“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 contacted Citywide for a new roof quote. They promptly returned my call and set up an appointment. The next day I received a call to reschedule and we agreed on a new day. That day no one showed up and after a 90min wait I called. They said they thought the appointment was for the next day, so I agreed to meeting them the following morning. Again on the next morning no phone call and they were a no show. I would give them less than a 1 if it were possible. Beware of a company that treats you that way prior to having your money, who knows how they will treat you after they get your money."
