Techs Who Actually Specialize in Heat Pumps

Stuck in Defrost? Won't Switch Modes? Heat Pump Repair in Lewiston, ME

Name: AAA Pro HVAC
Telephone: +1-866-805-8548
Price range: $$
Rating: 4.9

Heat pumps fail differently than standard AC or furnace systems, and diagnosing them requires understanding the reversing valve and defrost board specifically.

Auxiliary heat strip issues are checked alongside the heat pump itself.

A heat pump that seems to be 'not heating' is often actually a reversing valve or defrost cycle problem, which a technician trained mainly on standard ac systems can easily misdiagnose, which is exactly why heat pump repair calls in Lewiston, ME get treated with urgency, not a next-available-Tuesday slot.

Is ice on my heat pump's outdoor unit normal?+

Heat pumps have a reversing valve, defrost cycle, and often auxiliary heat strips that standard AC systems don't have.

Affordable Heat Pump Repair solutions in Lewiston, ME

The Lewiston area traces its roots to 1669 with the early presence of the Androscoggin tribe (the namesake of the county in which the city resides). In the late 18th century, in 1795, Lewiston was incorporated as Lewistown. The presence of the Androscoggin River and Lewistown Falls made the town an attractive area for manufacturing and hydro-power businesses. The rise of Boston rail and textile tycoon Benjamin Bates saw rapid economic growth rivaling that of Cambridge, Worcester, and Concord. Irish immigrants were recruited to build the railroad links and dig the canals for the textile mills. The Irish stayed, and worked the mills and established flourishing businesses, as evidenced by the McGillicuddy, Callahan, and other Blocks and the St.Joseph's and St.Patrick's churches. In the 1850 Census Lewiston was fully 23% Irish born. The increase in economic stimulus prompted thousands of Quebecers to migrate, causing a population boom; the populace rose from 1,801 in 1840 to 21,701 in 1890. In 1855, local preacher Oren Burbank Cheney founded the Maine State Seminary, the first coeducational university in New England and one of the first universities to admit black students before the Emancipation Proclamation. Lewistown quickly became associated with the liberal arts and was incorporated as "Lewiston" in 1864, a year before the college was chartered as Bates College.
