I've used Dial One Johnson's twice now and will not use anyone else. Jonathan was very professional and thorough. He explained the problem and what he had to do to fix the problem. He made sure everything was working before he left. I just joined their Advantage Club to ensure my AC, hot water heater and plumbing is checked and maintained properly. They may be a little higher than other companies but to me its well worth the extra. They have good coupons that help offset the extra. Thank you!!!!
