Haven Home Heating and Air Conditioning

I called haven home for a quote to replace a Garage Heater in my workshop, Sales came and quoted me $10000, I told him I could buy a Mr. Heater for $1100 and could Haven Home hook up the gas? He got back to me and said they needed to take a look at it to give me an estimate but if I accepted the job the estimate fee would be waved. A tech came in and looked at it, said yes they could do the job but needed parts. I was told on that Wednesday that he would be back this week, I waited Thursday and Friday with a no show, I called Tuesday and was told that I needed to accept the job via email and they would give me a quote. After the call I received an invoice for $190, I called and was told that this was a diagnostic fee and the quote for the job was $400. I explained that I was told the estimate fee would not be charged if I accepted the job, after an upsetting conversation the diagnostic fee was waved. I called around to competitors and was given a quote of $125 for labour per hour (Haven home is $175 per hour) and found a hook up kit for the heater for $50, no estimate fee or diagnostic fee to hook up an appliance. The total for Home Haven if I had paid the diagnostic fee would have been $600 to hook up a gas appliance!! I have cancelled the appointment with Home Haven and they will not charge me the diagnostic fee, (estimate fee). I have purchased a Heat Pump and Furnace from Haven Home a couple of years and wanted to keep all my heating with one company but the labour and parts are more expensive than there competitors. It is my opinion that the original $600 to hook an existing gas line is excessive and not inline with the competition approximately double the cost. The misunderstand over diagnostic fee or as I was told a fee for a quote can be avoided if you call around. Very disappointing.
