Allied Plumbing Heating & Cooling has been maintaining our furnaces & air conditioners for years. Regular technicians, Bob (now retired) previously, now Richard, have been great, with ‘clean & checks’ semi-annually. Upon Allied’s installation of 2 new furnaces three years ago, Richard did follow-up check-ups and found one had a minor gas leak which we had not detected. Have also used them for some bathroom & kitchen plumbing installs, as well as the sump pump issue. If we ever have a question, they readily talk by phone and/or make a return trip. Also, our son’s dog gets a nice petting from them! Definitely recommend the company.
