I called the famed T&G and they tried to rob me blind after they came out with some outrageous pricing for refrigerant.

I message prime time here on yelp and the pricing was up front and reasonable. Tech arrived within the arrival time frame was knowledgeable and completed the task within 20 minutes.

My 24 year refrigerator started acting funny last night- leaving out of town today and didn't want…read moreto come home to a mess. Today is Saturday and was able to get a technician to my home to evaluate the situation. Sherard was my technician and did a thorough job, diagnosed the problem, and while it wasn't worth repairing, gave me the information so that I could make critical decisions. And on a Saturday. I am so grateful I called Colonial and had such a professional and knowledgeable technician like Sherard who was available that day.

I had Colonial HVAC come out today to top off a brand-new R-454B central air system. I explained…read morebeforehand that the equipment was new, the system was operating, and based on the installation it should only need about half a pound of additional refrigerant. The technician looked everything over and agreed that roughly half a pound was probably about right. He was professional, and I have no complaint with him personally. The service-call charge was $119, which I considered reasonable. The problem was Colonial's refrigerant pricing. I was told R-454B was over $350 per pound, and that Colonial has a one-pound minimum charge, even if they only use half a pound. So my cost would be around $700 a pound. The total quote came to about $470. That means roughly $350 of the bill was for the refrigerant charge. For comparison, R-454B is currently being sold by established refrigerant suppliers in 20-pound cylinders for roughly $405 to $510 per cylinder -- about $20 to $25.50 per pound. One supplier is currently selling a factory-sealed Honeywell 20-pound cylinder for $420, or $21 per pound. Obviously an HVAC company has overhead and is entitled to make a profit. I don't expect them to sell refrigerant at their cost. But charging more than $300 for something currently selling in full cylinders for around $20-$25 per pound, combined with a one-pound minimum when the technician expects to use about half a pound, is a markup I'm simply not willing to pay.

In a world where things are getting more expensive, it's even more important to me to have experts who are able to keep things running! On top of his expertise and great business practices, Al is super nice and always very friendly -- I appreciate that he even remembered about elements of my life from when we'd talked multiple years prior to my latest service. 5 stars for sure!
