Recommended Customer Reviews

Amazing customer service!!!
Called because I had a water leak on Thanksgiving day. Called Complete Comfort and they sent Corey. Professional, knowledgeable, respectful, trustworthy and friendly. Corey worked out a plan and got the repairs done efficiently and with top quality work. I will recommend this company to everyone.

Horrible business. Company charged us for a 2 stage condenser but installed a single stage condenser. This is a price difference of $900. We have all of the documentation to back this claim. Chris who is the service manager/middle management admitted the mistake and only offered us a useless service package valued at $12.99/month for 1 year. That's a grand total of $156 to make up for a $900 charge. On top of the $900 they had our thermostat wired for a 2 stage condenser so our air conditioning ran inefficiently for 3 years meaning our electrical bills were likely significantly higher than they should have been. Chris repeatedly told us there is nothing he can do for us and tried to push the phone call off to tomorrow when I pushed back on him and asked to speak to the owner. Horrible service from a horrible company.

Alex, Joshua and Mathew were very skillful in resolving my plumbing issues, I appreciate they took the time to explain the work performed and answer my questions. They also displayed consideration in my home. Thank you.

Complete Comfort was very easy nice to work with. Their response time was very fast. Skyler and Josh came out to fix the wax ring on our leaking toilet. They were both very nice and knowledgeable. They diagnosed and fixed the problem very quickly! They even noticed some bacteria build up in a nearby sink drain and cleaned it up and poured some probiotic solution to kill the bacteria. Would definitely recommend them!

Complete Comfort Plumbing/Heating and their plumbers are a grade above the rest. Professional, knowledgeable, and service oriented. Corey came over and fixed both my bathtubs which were running brown water. He discovered that the previous plumber had incorrectly used galvanized steel instead of the proper brass material. Corey replaced the bad fittings and solved the problem. It is such a different and enjoyable experience to work with a top notch company.

Update: My floor has been repaired. They were unable to replace the damaged planks so Complete Comfort covered the cost to replace the entire floor in my laundry room. They are still unwilling to provide me with a detailed invoice but Chris has assured me that repair charges are based on the type of repair and that I was not overcharged. In spite of what he said and repairing their damaged, I feel $4,179.25 to install a coil that only cost $522.59 was excessive.
Original Post:
Dissatisfied with the repair cost and damage to my floor.
I was charged $4,179.25 to install a $522.59 coil. The installers were at my house 3 hours. Part of that time was spent trying to clean up the blue adhesive they spilled on my floor and baseboards. Attached are pictures of the estimate, floor and baseboards.
I contacted my AC manufacturer for warranty repair information. I was told Complete Comfort in Lake Forest is an authorized warranty repair for my unit. Since Google and Yelp showed high ratings for this establishment, I scheduled service with them. On 4/25/23 their technician determined my coil had a leak; it was not covered under warranty. I paid a 10% deposit and scheduled the install for 4/26/23.
I contacted Complete Comfort to request a detailed bill with parts and labor costs. Chris told me they do not provide detailed bills with parts and labor costs. I was told they do not charge by the hour but by the type of repair. Chris stated the installers would tell me the cost of the part at the install. When I asked the installers, they did not know the cost. The installers were at my house for 3 hours, part of that time was spent trying to clean up the blue adhesive they had spilled. I asked the installers for something in writing stating my flooring would be restored to pre-install condition I received nothing.
Once the installers left, I received a courtesy call from Complete Comfort. When asked if I was satisfied with the job, I said absolutely NOT because the installers had spilled adhesive on my floor. I was then connected to Chris and we discussed the floor damage and I again ask for something in writing stating the floor and baseboards would be repaired. I have received NOTHING. Chris stated they have a drywall guy who does flooring and he would be contacting me. Their repair person has canceled our appointment three times and has set yet another appointment for tomorrow. They are planning to try to clean the floor. I'm not sure what he is planning to do with the thumb size chunk of missing flooring the installers tore out.
I also told Chris his installers did not know the part cost. Chris told me it was $522.59. I asked if that meant installation cost was $3,656.66. I was told there is a lot involved with replacing a coil. I told him the installers were only at my home for 3 hours. I realize there is a cost for coolant however I feel I was overcharged because I am a senior woman.

I've been using another company for 13 years but it took Corey, the plumber, to actually fix our issues. They are so affordable and treat all customers as if they're the only ones. They also do heating and air conditioning. The company does regular maintenance on our Heater and A/C units, so we never have a problem (like we used to). I can't say enough good, except We are so happy to have found them. They give us such security.

I requested an estimate for a mini split unit for two of my rooms and possible remodeling of my AC duct. They came by and took notes. The technician was very pleasant. However, that was several weeks ago. I texted and called to ask them where the estimate was. Still waiting for them. Sounds like they are not interested. But it would have been nice to give us a courtesy call. Very poor follow up. Even if they came back, I now doubt if they can actually do the work and if they will be responsive after the job is done.
Will go somewhere else. Anywhere else.

$375 to replace a $20 part, and $750 total for two hours work. Their explanation is that they charge ""fixed rates"", not by the hour. Plus they recommended additional work (close to $1000) that a subsequent contractor said wasn't needed! There are many fine, ethical, and honest contractors out there. Steer clear of these guys.

After further inspection they didn't replace the water pump the first time they fixed the AC unit last year. Almost a year later it breaks. They realize the air filter cover was missing and clogging. I had warranty on the pump (pump that was never replaced?). They replaced the pump and now attaching the filter cover. $770 later. More than $1k of work in 365 days. Crazy. The AC technician was cool and great. But everything else lacks.
