I highly recommend Central Virginia Air.
Short story: affordable; diagnostic and proposed solution make sense; makes an effort to help homeowner save money; I will hire again without a doubt;
Longer story: I had another company inspect the AC system yesterday, and they said there seems to be a refrigerant leak due to corrosion in the evaporator coil, and suggested some very expensive repairs that were still just temporary. It felt like a ripoff, I knew I'd have to call them again in a few months, so I looked for someone else, and got a response from John. His prices are very fair, and I liked how he explained very clearly what the problems were. Everything he said made sense, there was no bs. He added refrigerant, and indeed found a leak at the coil, and found contaminants in the refrigerant. He explained the only viable solution long term is to replace the coil, which I had already suspected. He contacted the manufacturer, and turns out they'd cover the parts. He also noted some deficiencies in how the furnace was installed, which the home inspector missed. read more
