Requested for tune-up service on central a/c unit. Tech took panels off the central a/c unit and…read morespray 1 can of coil cleaner. I had already performed this service about 2 summers ago. I Googled what is generally performed for standard a/c tune up. Here is what I did not see the Tech doing. Did not check refrigerant level. Did not open up furnace to inspect or clean evaporator coils. Did not test refrigerant levels. Did not lubricate moving parts. Did not test capacitors or amp draws. Asked for hot water tank flush. Mine had a weird ball drain valve. The last hot water tank installer put in to let out more sediment out from tank. It was not standard. Power Tech had to procure a fitting in order to allow garden hose type thread to be installed. It did not help that my floor drain was clogged in the basement. Another drain was located and the Tech's self coiling hose had to be stretched out to extreme extent. It put pressure on the fitting. And that made it so the water was squirting out of the fitting and getting all over the basement floor. The Tech only drained the tank once. No flushing/purging/refilling to get all the sediment out. No safety and components check. Tech should have stated a proper flushing could not be perform. Tech was on the phone much of the time. I ultimately left the room so tech could take his calls. 6/24/26 I wanted to update my review after owner commented. When I hired you, your demeanor should have been professional from the start. No customer should have to call you back a second time to ask you do to a proper job. You initially earned my trust when I hired your company. You have lost my trust by performing a really subpar job, but still collected top tier pay for the services. You have cost me to spend double and hire another company who will do the proper job. The job you performed was something I could, and have, done in the past MYSELF. I would not recommend your company.

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.
