Recommended Customer Reviews

Osvaldo and Joel came out for an AC maintenance. They explained they found a problem that could have caused a lot of damage if not repaired. I appreciate their thoroughness in the inspection. Matt and Chris came out the following week for the repairs. I have confidence they did a fine job and assured me I can call if I have any problems. I've had Dial One Sonshine do a lot of work on my condo and I've been very pleased. Thank you Osvaldo, Joel, Matt and Chris for a fine job.

The Dial One Sonshine technician charged me $375.95 for a 45MF Running Capacitor as the test shows 41MF which is lower than the +/- 5% rating. I was given the impression that it may fail soon anytime if I don't replace it. and so I agreed to have it replaced. I later checked the market price of the capacitor and found that it is less than $20. The price given by the technician is just the part cost as the cost of labor is covered by the service call.
I called their office for there could be an error. I was given a run around answer.
I then called the owner who told me in short that that was the cost of busines. $20 cost of part would go up to $375!!! wow!!
i don't know, I think I got scammed.
Watch out guys when you call these outfit. You'll be offered a discount but somehow they'll kill you somewhere.

PAR EXCELLENCE! Installed new water heater and furnace. Positively satisfied EVERY step of the way. Great communications always, technicians fabulous. The work and cleanup, fabulous! Friendly, patient with all my questions, thorough, extremely professional. I highly recommend this company. Jonathan and entire team I cannot thank enough for such excellent work.

I have been a customer of Dial One for over ten years. Their service was great in the beginning and I have had no problem with the scheduling or on-time arrival of techs. However, in the past few years, I felt that each service call was getting more and more expensive, and chose to have my AC & hot water heater replaced by different vendors. Recently, Jeromey from Dial One came to do a routine maintenance on my 2-year old water heater. This service exceeded my expectations. Jeromey was very thorough, clearly explained everything that was done, and made suitable recommendations without any pressure. This was one of the best experiences from this organization I have had in the recent past. Thank you, Jeromey!

Juan came around to help us with our yearly maintenance on our water heater. Incredibly friendly and informative. It was like hanging out with someone i've known for years. Always great service from this company, can't recommend enough!

I've used this company about 10 plus years ago and they were good then I guess times have changed couldn't even get them to come out try it on the phone talking to the lady on the other end but unfortunately seem like my business wasn't important to them pretty much just got blown off guess I won't be using them anymore

I needed a estimate for replacing AC furnace and ductwork (all of it). I thought a company would be happy to get my business. I called them to schedule an estimate they sent a tech for $89 non refundable if I didn't use their services.
20 minutes after posting, the owner called me and left me a message with his cellphone number. I called him back and he was nothing but business with a great attitude. He said he was going to send me a check for the $89 that I was disputing. Thanks so much appreciate it.
I tried to get an estimate. They sent me a partial estimate. The salesperson only called me and emailed. No in person sales meeting.
I tried to get more information to go forward with the project but was left with no response to my inquiry. They stole my $89 fee with no possibility of excepting the partial estimate. Very disappointed.
To all of those needing help, go elsewhere. Goettl helped me out greatly after this company was an utter failure.

Maybe this will Get a response from them. Technician came out over a week ago for a broken AC Unit. He thought parts were going to be $3k for new circuit board, but was going to confirm and get me a written quote to fix unit. I found circuit board myself on manufactures website and it's $105. Still waiting on quote and company keeps calling and e-mailing wanting payment for the service call for service they still have not completed by getting me a quote.

I cannot recommend this company enough! Our HVAC broke on Tuesday, Saul came and took a look Wednesday, Matt and Chris installed our new HVAC all day Thursday, and Chai and Matt came and did some last adjustments early Friday. Our condo is old, and it caused some issues during installation that no one could have foreseen, but Matt and Chris were dedicated to doing the best job they could. They ended up working for nearly 12 hours and we still had a drainage issue (again this was the fault of our old, previously ill-maintained condo). But the company called us early the next morning and sent Matt back along with Chai, who handily fixed the drainage issue, triple checked that it was fixed, and double checked that there were no additional issues before they felt comfortable calling the job completed. All of the team were professional, friendly, and dedicated.
On a personal note, I have cats that are not allowed outside and all of the technicians made sure to close the door every time they went out. My cats never got out! They were very respectful of this, where some previous folks (not from this company) were not as careful. Matt, Chris, and Chai were so nice, it felt like having friends over. We spent a long time talking as they worked, and would be happy to use their services again, though with the thorough job they did, I doubt we will need to!
Thank you for our new HVAC and the great conversations!

Super shady company. Tried to scam my 92 year old grandma. Overpriced, tries to sell things unnecessarily, pretends you've had service with them and are overdue. Went around me, Gmas care taker and contacted gma after i told them I'm uninterested. If it weren't for me, my grandma would have spent over 500 on unneeded services.
EDIT: this was over a year ago and I addressed it with the manager at the time. I was hung up on and then manager proceeded to call grandmas house phone after hanging up.
Also, purpose for leaving this review now is because I received mail with a ""deal"" for service. The ad itself was scammy just like this company
