Gary and Brian are phenomenal workers! They take pride it their work. They are very knowledgeable,neat, clean and organized workers. Their prices are competitive with other companies. We used Northwood Heating and Air Conditioning in our previous home, now in our new home, and wouldn't have any hestitation to use them again! We will highly recommend them to anyone who is in need of heating or air conditioning. We were very pleased with the installation of our air conditioner, electronic air cleaner, and humidifier. Great job!!!
