We bought this house as a new build in 2007. I noticed during the summer of 2013 that the heat pump did not do as good of a job keeping the place cool as it did when we first moved in.
Shortly before the summer of 2014 I called Ron Brock's to come out, inspect the unit, and give it a tune up if necessary. Three other neighbors had replaced their heat pumps in the past year so given the performance of my unit I was expecting the worst.
The Ron Brock's technician discovered that my heat pump was low on refrigerant, and hunted down the leak. Unfortunately, the leak was in the evaporator coil in the attic. The coil would have to be replaced.
I decided instead to pursue the replacement of the entire unit. As requested, the Ron Brock's rep gave me quotes on four different units, each with a different SEER rating. I thought the prices were - quite frankly - very reasonable. I choose the 4-ton 14 SEER unit with a 10-year warranty.
The Ron Brock's personnel showed up on time at 7am and were finished by about 2pm. They were polite and they cleaned up after themselves. (I HATE it when contractors leave a mess behind.)
While I did read the two other reviews that were negative, they do not reflect my experience at all. All the staff is professional and polite. The price was very reasonable. The installation went very smoothly, and the new unit is keeping us nice and cool.
I could not be happier
