• If you are looking for a reliable, professional, and fairly priced HVAC company, look no further. You'll find prompt responses from their staff, who provide prompt service. As a busy real estate agent, I know I can count of them to take care of any client (or friend) I refer to them.

• I had my HVAC replaced and the service I received from my initial call and inspection to installation was first class. I had used another local company for years but I have very happy with the switch.

  Louise S.★★★★★

• First time customer and I will be back. Best mini-split estimate we received. Installed within 3 days. The crew did a great job and answered all my questions.

  Sharon C.★★★★★

• Charged me $788 to replace a 12 inch gas line section. Shame on me because I later found out TJ Fannon would have charged $278. The worst part was after the plumber finished, he walked up from the basement to my kitchen with a lit cigarette after bleeding the gas line for air. I do not recommend.

• BL James was excellent. Our AC failed on a Wednesday and we contacted BL James Thursday afternoon requesting a quote for a replacement system. They sent a team member the next day to review our needs and spec out two systems at different prices. There was no pressure to upsell or push us into a more expensive system. We received quotes for those systems within an hour after the appointment, and after we selected a system we were able to schedule a replacement of our current ac/ heat pump for Monday. The team arrived promptly Monday and completed the work quickly and cleanly, putting down mats through the workspace and cleaning any debris and trash on completion. The work is fantastic and has been working great. Overall fantastic experience and we would highly recommend BL James for local hvac work.

• Jorge did a great job. He came early and worked very fast. I would call and asks for Jorge for any plumbing issues or questions. Highly recommend using B.L. James & Son for all your HVAC and Plumbing needs. Thank you Jorge! Mauricio (with B.L. James) just came and did a fantastic job too! He flushed out the heater and replaced the condensate drain line neutralizer. Unbelievable! Hose is pretty amazing too! These guys are all top notch. They are punctual, fast, super knowledgeable and honest.

• *** BEWARE -- READ THIS *** If you are looking for a HVAC company READ THIS before you talk to B.L James & Son. I talked to one of the technicians, Mark, about a small commercial job for my business. They totally lied about what the "cost" of the job was vs what the final bill ended up being. Mark actually said to me that he quoted the job very high just in case it took longer or more equipment was needed. I was assured that I would only be charged for parts and labor. In the end, I received a bill that was almost twice as much as it should have been and then threated to "rip the A/C unit out" (said specifically by Mark), send me to collections and put a lien against me if I did not pay the bill immediately. This company should honestly be investigated for corruption. Don't make the same mistake I did; find another HVAC company. Update from owners response: The owners response is a complete LIE! I sincerely hope that people read this. Your employee, Mark, convinced me NOT to get another quote by saying I would only be responsible for parts and labor. I was charged thousands more than I should have been. There is NO WAY that all the reviews for this company are accurate or true reviews. I have had multiple issues with your company from the beginning. Nothing, however, to this level of neglect, dishonesty and manipulation. Take a look at Yelp. That review site gives a better idea of what kind of company this is.

• Had BL James install a pressure reducing valve on our water line after a home inspection showed the supply pressure over 100psi. The lower pressure solved problems we were having with a shower valve and our ice maker. Easy to schedule the work, final bill came in line with the initial quote despite the plumbers running into some unexpected challenges. Not cheap, but reasonable price and work well done - would use again.

  Ben H.★★★★★

• This company is such a sham. They quote you one thing and then try to charge you another. There is NO WAY they have so many positive reviews. They are either mostly fake or the company has gone totally down hill recently. FIND ANOTHER HVAC COMPANY!!
