So.... On Friday before an arctic cold snap of -15 degrees coming the next Monday, which was also a…read moreholiday, the gas valve on my boiler went out. I called around to try and find one locally. No luck for my valve for LP (Propane), and no valves with conversion kits available. I was able to order one, I bought it, and paid $175 to next day ship it for Saturday. It came and I had it installed, but it wouldn't light all the burners! Two or three of seven might light, until perhaps a minute later, and then if you blew on then, they would all light, but the boiler would shut down if you didn't. No matter how many times we tried, they would never all light, and instead one or two would light, and the rest would just blow gas into the boiler room! Talk about risk of explosion! So there I was with -15 degree temps coming in 24-36 hours and Monday was a holiday. My first guy told me that there didn't seem to be enough pressure of gas coming into the house and to call the propane company because he thought they had a bad regulator on the tank. I called the propane company and they informed me that all the pressure and lines needed to be checked before they would send anyone out, and they recommended I call Premier Air heating and cooling. At this point I was desperate, so I called! I spoke to someone immediately when I called who put me in touch with the Helena rep, Lex. Lex agreed to meet me at my home in 2 hours and he was there right on time. The first thing Lex did was to check EVERYTHING, clean EVERYTHING, and otherwise ensure that all components were working, one by one, before eventually he was able to conclusively determine that my brand new gas valve, was bad! It wouldn't let much gas into the burners at first, and took almost a minute to build up gas pressure to the normal 8-9lbs. He also determined that there was no problem with the pressure coming into the house from the tank outside. It was the bad valve which wasn't letting enough through for way too long for the burners to light normally. So essentially what was happening was that the brand new bad valve I had just installed would have only been good for causing a gas explosion. Thank GOD I was able to get such a talented professional out to help me on SUCH SHORT NOTICE before a holiday weekend and an arctic air blast. AND..... he just happened to have a universal valve with an LP conversion kit that, after installation, worked perfectly and got our home back online with heat and hot water again! Sure, it was a very expensive valve, and pricey service, but Lex earned every penny, and I was so grateful to have this serious problem fixed in the NICK of time before the arctic freeze! Thanks Lex and Premier Air Heating and Cooling. I WILL be calling you guys again if I need you, and recommending your services!

That was great. He was friendly and professional and had our problem figured out in maybe 10 minutes - it was the air inducer motor. He did not have that part in his truck so he promised an estimate first thing Monday morning. He kept his promise with an email and a phone call right around 8:30am. The estimate was $470 for the part, $30 for part delivery and $60 for the 2nd home visit to install (after $170 for the emergency), or about $560 now, and $730 total. I price checked another Bozeman HVAC firm and saw on the internet that one other person on Amazon claimed this price from another HVAC co. But Amazon sold that part for $85 and free shipping!! I was a bit nervous about messing with a gas appliance, but this inducer screws to the wall of the furnace with just 4 screws and 2 plug-in wires. You do not touch any furnace parts that carry gas. The how-to video lasted 5 min. I took maybe 45 min. My furnace fired right up as so many Amazon reviews noted. So if you are non-mechanical, you are getting a fair HVAC price. If you can hold a screwdriver, perhaps consider saving $480!? I did need the emergency call to tell me what was wrong and that was totally fair.

Though a decent man, I soon realized we were being overcharged on many aspects of the projects. Many of the subs were charging us additional fees for travel because of our location. A neighbor with a similar issue was referred to Excel Plumping. We also contacted Jeff and were amazed that his bid was less than half what the contractors sub bid us. Jeff came and did the work in-between jobs and on his own time. I grew up working with my father who is a contractor specializing in plumbing and I can tell you Jeff dis an outstanding job.
