We have used Howell’s for years. They have put a new heat pump in our old house and the house we are in now. We have always signed up for their maintenance twice a year. The individuals that have come have been very professional and knowledgeable. They go about doing their work, but will always take the time to answer any questions and will let us know if we need something and why. On a couple of occasions we have had to call on the weekends. Our calls have been answered quickly and if the problem can’t be solved over the phone, the tech will be right out. I recommend Howell’s whenever I have the chance.
