Reviews
Write a ReviewBeen a terrible experience with this company. I had a heat pump installed in February of this year by them. The permit is still outstanding! The city has sent numerous requests asking for more information. Even though the company gets the same notice from the city, I would share the email from the city with Oscar in their office. Several times, Oscar would reply, that he will work on it "today". One to two months later, the city says nothing has been done since their emails. I get no response from the install manager either. Yesterday, I spoke with Steve, who claims to be a manager there and he was supposed to get back to me yesterday afternoon. NOTHING. The above are JUST A FEW of the problems I've had with them! If you have nothing to do, but make many many phone calls, and don't mind the headaches, then hire this company. if you want a smooth install, and don't like headaches, go some where else. They leave me no option but to get a lawyer.
They helped us with a leak in our AC system, and sold us on their VIP maintenance package, claiming that they would see us within 48 hours of a request. Their work was shoddy and the leak started again less than three weeks after service, but by the time we reached out for help JJ Heating went out of business. They sold us a meaningless VIP package and did bad work. They are simply not responding to phone calls or emails and we only know they went out of business because of reviews on Yelp. Terrible experience.
The whole experience with JJ was fantastic! First, Alan came by and knew exactly what I needed with the new AC and furnace. He was very detailed, excellent communication, and worked out a fantastic price for me with no haggling. When it came to the install day Javier and Abraham came by and did a fantastic and beautiful job. They were very friendly, professional, and kept everything clean! The whole process really surprised me. Very good communications with the company on logistics and everything was very transparent. Thanks guys!

About JJ Co
Customer experiences with JJ Co appear highly inconsistent, ranging from smooth, professional installations to significant service and communication breakdowns. Some customers praised staff like Alan for detailed consultations and fair pricing, and installers Javier and Abraham for clean, professional work, while others reported unresolved permit issues, unreturned calls from staff like Oscar and Steve, and recurring AC leaks that went unaddressed after the company reportedly went out of business. This disparity suggests the quality of service may have varied significantly over time or depending on the specific team assigned to a project.
