Terrible ans overpriced! Quoted me for 2 days worth of work because they would have yo do digging in my dirt basement. They did less than 6 hours worth of work and ZERO digging. When we called to ask that rhey adjust thier cost becauase they didnt do the work they said they had to he refused to and said we agreed to that amount when they quoted us. Ended up paying $5000 for a $700 furnace

Frontier and their professionals are great. They have done several installs and do maintenance for my business: heating, cooling, freezer, exhaust hood, ice machine, compressors and air handler for kitchen. Their service is exceptional and dependable.
