"The alarm, when it goes off, is very loud!!! This is a good thing. If we ever need to activate it, it will definitely scare off anyone trying to come into our home. We can set it off from our phone or from the keyboard control panel that we installed in our bedroom. We feel very safe with this purchase."

"Very well!"

"We called Dalcon Electric when a car struck a power line outside of our building and knocked out the electricity to our building. They were quick to respond in an emergency, courteous and professional. They helped us get our business back on track in a pinch. Then, we hired Dalcon to replace all 53 outdated outlets in our building. Dave and his crew (Jack and Billy) completed this efficiently and with minimal disruption to our business. When we needed to install emergency exit signs, Dalcon provided by far, the best quote for the work to be done compared to many other handymen we had considered. Jack and Billy installed our emergency signs and cleaned up the area where they had worked leaving it just as, if not better than, how they found it. Everyone at Dalcon is courteous, prompt and responsive. Dave, the owner, came in person to our office to discuss each project to be done. Scheduling these projects was a breeze, Sarah and Suzanne in the office were very responsive and made sure our concerns were addressed. We scheduled the projects out over time, but when a sooner date became available, someone from Dalcon would call and ask if that time would work for us so we could have our projects completed sooner. We would definitely work with Dalcon Electric again."

"Very professional in both sales of the right product AND flawless and timely installation. You can stop your searching for vendors...stop sns start with Air Sharks."

"Michael showed up on time and even called me as he was on his way to my home which I appreciated. He not only fixed my issue buy also explained to me how things work electrically. I would hire them again for any electrical issues and hope I get Michael again. Your company is lucky to have him."

"HIGHLIGHT OF REVIEW (and reason for the two star rating for price): This was the first moment where I felt disappointment with the services provided by Dollens Electric. They had spent two hours and charged me $509 ($374 for first hour plus another $175 for a second hour of work on that Friday’s first visit) in order to reach the conclusion that they needed to go and inspect the attic to see if there were damaged wires up there preventing power coming to the outlets. I find this a very high and expensive price to pay and still not have the source of the problem identified. Jason came back the next morning with a partner, Elijah. He sent Elijah up into the attic and, within 15 to 30 minutes, Elijah found a damaged wire that was preventing power from reaching the outlets. I silently thought to myself that if someone had gone up into the attic during the first visit, then this damaged wire and source of the problem would have been found sooner and saved me a lot of money. MAIN/FULL REVIEW: Four outlets at my mom’s home went out at the same time: one in the kitchen and three in the dining room. An under cabinet light connected to the power in the kitchen outlet also stopped working. The circuit breaker had not tripped; so, I told my mom that we should call an electrician. I called Dollens Electric based upon their name appearing in a booklet that had come in the mail a few years ago listing providers of various services for home maintenance. A woman answered the phone, and I asked how much it would cost for someone to come out and diagnose the problem and then fix it. She said that she would have one of her electricians call me and give me a price quote. In less than an hour I received a phone call from Jason, and I described the problem to him. He said that there is a $334 charge for the first hour to come and troubleshoot the issue. Each additional hour after that would be $175 plus any materials needed for repairs. He also volunteered that I try to go and turn off and then on the circuit breakers in order to see if the four outlets would work again. I told him that I would do that and then call him back with a follow-up. After ending the phone call, I went and turned off and then on the circuit breakers. This did not fix the problem, and the four outlets still were not working. I thought that the prices I was quoted were really high; so, before calling Jason back, I reached out to a friend who is a handyman. I told him that maybe the plug receptacles were bad and that I didn’t want to pay $334 for an electrician to come out and just tell me that. My friend said that he would come and take a look. A few days later, my friend came out and did some tests on the outlets using his tools. He told me that there was actually no power coming to the outlets and that the problem was not the plug receptacles. He said that there might be an issue with the electric wires in the attic, and that I really did need a trained electrician to come out and find the problem. So, I called Jason back and scheduled for him to come out to my mom’s house. Jason arrived in the afternoon on a Friday. I told him that there was no power coming to the four outlets and that my friend had said that someone needed to go up to the attic and inspect the wiring up there as a possible source of the problem. After that, I allowed Jason to do his work. He spent the following two hours opening various receptacles around the kitchen, dining room, living room, and family room. He ran tests on these with instruments he had. He had a tool where he would wave it along the walls and it would make various sounds. After two hours of doing this, he stated that he would need to come back the next day with a partner and go into either the attic and/or crawl space in order to see if the problem could be found there. This was because even after two hours he had not been able to identify the source of the problem. This was the first moment where I felt disappointment with the services provided by Dollens Electric. He had spent two hours and charged me $509 ($374 for first hour plus another $175 for a second hour of work on that Friday’s first visit) in order to reach the conclusion that he needed to go and inspect the attic to see if there were damaged wires up there preventing power coming to the outlets. I find this a very high and expensive price to pay and still not have the source of the problem identified. Jason came back the next morning with a partner, Elijah. He sent Elijah up into the attic and within 15 to 30 minutes, Elijah found a damaged wire that was preventing power from reaching the outlets. I silently thought to myself that if someone had gone up into the attic during the first visit, then this damaged wire and source of the problem would have been found sooner and saved me a lot of money (remember: I had paid $509 for two hours of troubleshooting on the first day with Jason leaving while still not having found the problem). Elijah, who was in the attic examining the damaged wire, and Jason recommended that I fix the problem and restore power to the outlets by installing a dedicated line. I told them to go ahead and do this. They did this work professionally. I asked them, since Elijah was up there, to let me know if they identified any other wiring issues. Elijah found some separate wires that he and Jason said needed to be extended, and I told them to go ahead and do that work as well. At my request, on his way out of the attic, Elijah also looked at an attic fan that not worked for awhile in order to tell me if the problem was electrical or if the fan itself had just stopped working. He confirmed that there was power to the fan and that it was just the fan that needed to be replaced. This was good to know. Overall, Elijah was a very pleasant and hardworking young man. The final step to this electrical job was for Jason and Elijah to bring the new, dedicated line into the panel and connect it to a new circuit breaker. Jason charged me $84.33 for an arc fault / ground fault circuit breaker for this new line. Power was restored to the four outlets as well as the under cabinet light. At this point Jason said to me that it would also be recommended to change some of the other existing circuit breakers in our panel. I had not planned on this, but I am the type of person who trusts the expertise of people. So, if my electrician says that the home needs some new circuit breakers to replace still working circuit breakers, then I will agree to it even though I don’t understand why. We were approaching three hours of work time for the second day’s visit, and I hoped that this additional work would be completed without going into a fourth hour. It was completed within the third hour of work for the second day, and I therefore ended up paying $525 for three hours of labor on the second day (rate was still $175 per hour since this was a continuation of the same job started the previous day). So, over the two days, I paid $1034 for five hours of work. Since the job as a whole was $1427.66, you can see that $393.66 of the total cost was for parts and materials. I had already mentioned that $84.33 of the materials charge was for the required new circuit breaker for the new dedicated line that had been put in to restore power to the four outlets. I expected something like this. And the charge for the wiring used for that line was $32.90. This was also expected. I was surprised by how expensive the circuit breakers that Jason installed to replace my already working but older circuit breakers cost. Again, I did not expect this because it had nothing to do with the original problem of the four outlets not working, but Jason, as I wrote above, said that this was recommended work to do. In particular, Jason replaced some of my older but still working circuit breakers with a type called “quad” circuit breakers. He charged me $151.89 for the circuit breaker part called 50/30 quad Eaton breaker, and he charged me $96.99 for the circuit breaker part called 15 Amp 240 Volt Quad Eaton Circuit Breaker. These two parts alone added almost $250 unexpected cost to my invoice for"

"Great service"

"Our Service Tech, Alex Peck, arrived on time to perform the annual check up & tune-up of our HVAC System. He was very professional and following the Tune-Up asked if there was any other items that needed done or looked into that he could take care of. His services were very much appreciated and very professional. Lee"

"The plumbing technicians came out as promised to assess the leak. They were both very courteous and kind and assessed the damage. I am giving three stars because they estimated the cost to be almost 250% higher than what the actual cost was to fix the issue. I am sure there are customers out there that would just accept any bid however, please get multiple beds for these projects, especially when working with this company as they will inflate the cost to take advantage of the situation. I ended up only paying for the $79 estimate."

"We had a wonderful experience with Comfort Energy! The service person, whose name was Chance, did a thorough evaluation of the problem with a focus on saving us as much money as possible, to either repair or replace our 30-year-old heat furnace. He quickly determined that our inlet filter was too dense (it was a Merv 11 and should have been a Merv 8) and that that was probably causing the heater to go off an on every 5-10 minutes. He then tested and confirmed his hypothesis. He also performed a CO test to make sure there wasn't anything more serious going on. Finally, he gave us a good idea of replacement options, which we should probably do before the next Winter, but not necessarily right away. All in all, this is exactly the kind of assessment we needed, and it cost orders of magnitude less than what was estimated by the first service company we had come out. Chance was great, and Comfort Energy is our go-to for heating and cooling service and/or installation from now on."
