September 2014 I Signed contract to pay half up front the rest at completion of job I payed 3/4 of bill up front. The end of October they hooked up a new furnace and then I was told it was going to be 5-6 months for them to hook up the rest of the system they said it had to be 70deg outside:(. So I called again in the spring when it was time and asked when they would be out to hook up the coil and heat pump. Well the lady in the office acted like the work was done and asked for payment:(. So I fought to get the rest of the equipment installed. Well about a month later an installer came down just to say the 1 1/8 line set they quoted me couldn't be bent so I would have to find the 90 deg elbows before they come to install it. I got them the next day called them up again. To have them once again demand payment, I told them I would pay for the extra trip down and would pay for the rest when it was done. A month later I get a call to come install the rest of the system, the calls are ALWAYS the same day, no warning at all and both my wife and I work so I've always dropped everything to GET THIS DONE but today I was already in Denver, so I told her I wasn't going to be home. The lady in the office proceeded to DEMANDED payment I told her I would pay when the work was done, but it's been 8 months and the unit is not hooked up, and this is really bad customer service. This made her more flabbergasted and said I would be hearing from John the head of the company to tell me this was going to collections(keep in mind only about 1/4 of the bill was left something like 920.00). A couple of weeks later they got the system finely hooked up and gave me the bill they didn't charge any extra so I cut a check gave them a extra 100 bucks for a wasted trip and dropped it in the mail, about a week later I get an invoice that the job was completed 9 months ago when I sign the contract of labor and so I was more then 120 days past due, that took the lifetime warranty off the equipment that just got hooked up. Plus the system was running so badly I had to call another company to come fix there (His Words) "poorly done work.".
So moral of the story if you don't pay over 75% because there taking a long time you'll get the work "poorly done" and you might take a credit hit, or you could pay 100% and then have someone else come and do the job, or you could be smart and just stay away from these guys.
I tried to make it the best for them I hooked up equipment like the gas line, set the heat pump, plumbed the drains, plumbed the high efficiency intake and exhaust on the furnace, wired 110 to the furnace, wired 220 to the heat pump, wire low voltage to the thermostat.
In 9 Months they built 2 ducts each smaller then 3'X3', hooked up filter box, set furnace and coil, hooked up line set, charged system and ran low voltage wires from furnace to heat pump.
