"Dustin was my initial point of contact who met with me and came up with the proposal. Jeff, Josh, Bayron, and Devan were the technicians who did the installation. Both Dustin and the installation team were very courteous and patient about answering questions. The installation went very smoothly."

"My prior water heater, a 50-gallon tank, started leaking after 15 years. I called Streamline to confirm that it needed replacement, and to replace it. I was considering a tankless water heater already, and the first tech walked me through the pros and cons, then wrote up an estimate. Two additional techs came the next day to install the heater and the necessary gas and power lines. The only issue I had was that one of the newly installed gas fittings leaked gas into the basement. I shut off the supply valve and called Streamline, and they came out within half an hour to fix it at their expense. Mistakes happen, and I was impressed with how professionally they corrected that one."

"Carolina Comfort installed a new HVAC system at our home. They did a great job from the original recommendation on the type of unit- a ducted split system- to a quick scheduling of the work- and lastly installing the system. Ryan, Dylan and John were great- very polite and professional and got the system and fully installed and running within the time frame promised. Would definitely use them again."

"Our motor burned out the week before Christmas during the night. I called Alpine and the serviceman was at our home the next morning.
He determined the problem, let us know the cost and the part was ordered immediately. He installed the part as soon as it came in. We have been standing customers with Alpine and the prior HVAC company with a service plan. We appreciated their responsiveness and flexibility. R Hall Durham

"The initial install went well.
Since the install we've had to call the provider out to our home twice. 
1st time we call the provider to let them know that we had an energy assessment done, provider was very upset that in the report there were several items that needed to be addressed.  I informed the provider that I gave the energy assessment details to him not to contact the energy auditor but as a guide to assist Yellow Dot to make the corrective measures on the items listed. 
The day of to perform the corrective measures......things didn't go so well.
The worker showed up at our house, then was called to another job.  When I called my contact at Yellow Dot, I was told that he was working too slow, and that they would have someone else come out the following morning to finish the work.  OK........
The following day the next worker showed up, and i greeted him to let him know that my hisband was there to go to the house when he was ready.  He stated that he was trying to figure out what needed to be done since he was provided no direction by Yellow Dot, but he has the energy audit in his hand.  I called my contact to let him know, and my contact stated that he was at the vet with his dog, and that he would be to the house after he was done at the Vet.  OK.........  When my contact showed up, he and his worked left.  Just left, didn't tell my husband why they were leaving without completely the work. 
I called my contact, no answer, called the office, and they said that I would need to wait till he responded since he was out of the office for the rest of the day.  I asked to speak to the GM.  Relayed what had been going on the the GM, and let the GM know that we were not happy, and that they needed to complete the work today, since this is the 2nd day and if that wasn't convienent for anyone that we would be home all weekend, to let me know what time they would be by.  I received a call about 30 minutes later letting me know that someone would be by the house to complete the work that day.
2nd time:
Having insullation installed in our attic, crawl spaces, and eves.  Insulation provider noticed that there were some leaks in the transfer unit to the HVAC and duct work to the transfer unit is pulling away, creating gaps, letting cool/heat escape into the attic. 
Called Yellow Dot to schedule an appointment, giving them 1 week to get us on the schedule, and secured an appointment for 7/13 @8:30am.  Received a call on 7/10 requesting that they move my appointment to 7/14 after 3:30pm, since they had customers with more pressing AC issues.  Explained to them that I had my insulation provider scheduled to come Wednesday at 7am to finish work that had already started, and we were waiting on Yellow Dot to complete the work.  Reluctently reschedule to 7/14 after 3:30pm.  TBC......
7/15/15:  So Yellow Dot didn't show when they were scheduled on 7/14/15 @ 3:30pm.  I received a call at 5:05pm 7/14 to let me know that they would need to reschedule since their people were not free to perform the work.  I spoke to the manager yesterday evening, and said that i had booked this appoint about 2 weeks out so I wouldn't have these issues with no shows or work not being performed.  He agreed, and sent someone this morning to finish the work at 7am.  With a small child and company over, not really what i wanted but worked need to be complete so I can have the other vendor for insulation compete his job.

Overall: Yellow Dot, being rated A for workmanship and customer service needs to be down-graded to a D-C level.  I didn't feel that we were important to the company even though we had spent 20k on work in November 2014.

Install Boiler questions, answered by experts

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

Due to fuel line connections and venting complexity, professional installation is required for safety and efficiency.
