  • Kurtis came early for the appointment. He was polite and efficient and did a great job cleaning our boiler after 3 years of neglect. He explained what he was doing at each stage and even crawled between my house and the neighbours to get the CO/2 reading. Thanks Kurtis for your professional attention. TH (Toronto)

    ian M.

  • I just had a heat pump/air conditioner installed on my second floor in the master bedroom, and I’m really enjoying being able to sleep better. I called on a Monday, met with the sales rep on Tuesday, the part was ordered and took two weeks to come in. Wonderful prompt service installation took about half a day. I have used LB heating for several years and I highly recommend them. They installed my new furnace, four years ago, the service, my Central air conditioner. And now they’ve installed this heat pump for me. No high-pressure sales just quality work by family business.

    Tricia W.

  • I've worked with LB Hearing for over 10 years and two houses that range from radiators/boiler to forced air + airconditioning. They are so supportive and responsive everytime I've called and trust them completely.

    Tanya M.

  • Great service and follow through, We have be using them for years.

    roguemusiclab

  • Our 17 year old combi boiler finally had to be replaced. After a fair bit of research we purchased a Viessmann 100 combi from L&B as it was one of the few vendors we spoke with which actually understood the products it is selling. Its pricing was competitive and the installation went very smoothly and left our basement cleaner than when they arrived.

    Doug L.

  • We've used LB heating for close to 10 years with no issues. They installed our new furnace and do a yearly cleaning/inspection. They are courteous and show up when they say they will. The last guy showed up early which worked out better. He also showed me how to check for the correct filter.

    Diana F.

  • Totally fantastic professional installation of our replacement Veissmann boiler and associated gear, re-fitting into adjusted space etc in our detached home. So excellent to be able to rely on highly skilled and trustworthy contractors, with long-term business values that truly take care of customers ongoing. Thankyou guys!

    Peter E.

  • A very good job, very professional and available. Quick response. We were very happy to have this team to solve our problems.

    Deborah C.

  • Amazing workmanship and attention to detail and just fun guys to have do work on my house. They know their stuff!
