Good price, good quality provided and fast installation. Best decision we made in choosing DeMark Home Ontario.
Our old furnace broke down and we needed a new one ASAP.
Mike was very helpful and expedited the installation the next day.
Crew was on time and did a great job.

Highly recommend.

I highly recommend this company. An absolute pleasure to deal with from start to finish!! Office staff was very helpful and diligent in helping me after my furnace just stopped working. The installers were very clean and efficient. They left my home just as the way it was before they got here. If you are looking for a furnace or a/c you need to contact them. Five out of five. Great work and thank you for all your help.

DeMark Home Ontario installed out new heat pump and its been a game changer. They were quick, friendly, and pro at what they do. Our house is now cozy and saving us some bucks, thanks guys.

Thanks David for the insulation and thanks to Mike for the Easy and smooth transactions.

excellent technician and his helper work well together, removing and installing a new furnace there always challenges and they excecuted very well.

My Air-conditioning needed replacement so i contacted many large and small companies for quote. MIKE from DeMarks, gave me a competitive price. He wasn't the cheapest but his commitment to quality work convinced me to go with him. He sent me a technician (Eddy) who come to my place and said the work was complex and walked away. Within 5 min. Mike called me to tell me he was going to send me another guy. The new guy (Ahsan) came qccepted the work and started on it the next day. It took him two and half days to complete (complex) work. During the install Mike came to my place and made sure things were done properly. DeMark is a top notch operation and i highly recommand them. The high rating of this company on homestar is well deserved

We are very happy with the great work that Ahsan and his partner did to replace our decades-old furnace with a high efficiency one. They were super polite, answered my on-site questions fully, and worked diligently on a more complex job than was expected. They left the work area in a clean and tidy condition and carefully protected the rest of the home from foot traffic and debris. Mike DeMarkHome gave the original quote (very fair price) and he, along with his office assistant Anna, were a pleasure to communicate and do business with.

Recently we had our tank serviced with removal and new installation.Very happy with their service and professional etiquette.Definitely recommend this company.

We replaced our air conditioner with DeMark under monthly payments and they made the process very convenient for us. Mike walked me through all the details of the program over the phone and was prepared to answer all the questions I had. He was able to schedule us in for an appointment that same week. The technician did an excellent job and cleaned up after himself when the job was done. Now we have a brand new AC for the summer. Good, honest work.
