Installed 2 Mitsubishi indoor units 9,000 and 12,000 btu and two zone Outdoor Heat Pump Unit. From day one our experience with Richair has been outstanding. After receiving 4 estimates, Richair' was the best and the professionalism of the sales team reinforced our decision. After signing the contract we had some delay in getting approvals from our building. Richair did what they could to assist in the process and patiently waited as we attained the approval. The installation team was excellent and very professional. The workmanship was very outstanding, in fact my electrician went out of his way to praise the way they did the job. Of special note, I had hoped to put the outdoor unit further away from the building, off my wood deck. Richair reviewed this and while they said they could do it and it would be more money, due to the additional coolant and piping, they strongly recommended that we not do it as it would make the units less efficient. I appreciated their professional opinion and honesty. Other vendors never mentioned an issue with putting it out further. I would definitely use Richair again and recommend them to anyone.
