There were many impressive options to choose from but I eventually settle on MMS Heating & Cooling. The glowing reviews and the impression I got from my initial interaction with Matt was the deciding factor. The quote I received from him was reasonable and competitive. He came across as professional, knowledgeable, responsive , accommodating and courteous. They arrived punctually to start the work as per our agreement and did an outstanding job. They completed the job on time exactly as Matt had indicated they would. The water heater was professionally and neatly installed without any issues or problems. I would have no hesitation in recommending MMS and Matt for any of the services they render. Thank you Matt." > Source: Dylan (5.0, via HomeStars) > "Matt arrived on time, succesfully completed the job and cleaned up afterwards. Very pleasant and polite." > Source: Anonymous (5.0, via HomeStars) > "Very Professional. Matthew texted me to update me on his arrival time and he and his partner were professional, efficient and courteous, explaining everything they found during the furnace maintenance.

Electrical, gas and plumbing are licensed trades almost everywhere (for example ESA for electrical and TSSA for gas in Ontario), so check your provincial regulator that the contractor is certified for the work before you hire. - A construction lien is a real risk: in every province an unpaid subcontractor or supplier can register a lien against your home even if you already paid the main contractor. Hold back the statutory amount (commonly around 10%) and get signed lien waivers as you pay. - Confirm they cover your area and can actually come out in your timeframe before anything else. - Read recent reviews for reliability and turning up on time, not only the quality of the work. - Agree the call-out fee up front, and be wary of large upfront deposits for an emergency job. ## Contact - Phone: (416) 670-9249 - Website: https://www.mmshvac.ca --- Source: MyTrustedTraders, https://ca.mytrustedtraders.com/traders/mms-heating-cooling-inc Real public evidence only: every figure traces to its named source.
