Do heat pumps work in Lowell winters?

Lowell sees about 45 nights a year at or below 20°F. A cold-climate certified model keeps the house warm without leaning on backup heat. The average winter low is 22°F, and the heating season adds up to 6,095 heating degree days (NOAA 1991-2020 normals).

How much does it cost to run a heat pump in Lowell?

A typical 3-ton central heat pump (17.0 SEER2, 9.0 HSPF2) uses about $2,978 of electricity a year for heating and $322 for cooling in Lowell, at the Massachusetts average of 30.4¢/kWh. The most efficient models cost less - see the rankings above.

Is a heat pump cheaper than a gas furnace in Lowell?

Not on heating alone at today's prices: about $2,978 a year with a typical heat pump versus $2,247 with a 95% gas furnace (Massachusetts averages: 30.4¢/kWh, $2.42/therm). A high-HSPF2 model narrows the gap, and a heat pump also replaces the air conditioner. Against propane, oil or electric heat it is usually far cheaper.

What size heat pump do I need for a 2,000 sq ft house in Lowell?

With average insulation, roughly a 5-ton system: the estimated cooling load is 27,600 BTU/h and the heating load 54,000 BTU/h. Use the size calculator for your own house, and ask installers for a Manual J calculation.

Estimates use the unit's rated SEER2 and HSPF2, full-load hours derived from NOAA 1991-2020 degree days, average residential electricity prices from the U.S. EIA (12 months to July 2026) and fuel prices from EIA (2025 for natural gas, week of 2026-10-05 for propane and heating oil). Very cold days that need backup heat are not modelled. Federal minimum for comparison: 14.3 SEER2 / 7.5 HSPF2.
