Albany has recorded both extremes in the same record book: a low of -28°F in January 1971 and a high of 104°F in July 1911. That range means a furnace, boiler or air conditioner here can fail in either season, and a frozen pipe is a real risk in deep winter. Before you hire, ask about the permit. The city's Department of Buildings says a permit is required for all work to mechanical systems, including installation or changes to heating systems, though replacing existing equipment with something consistent with the original specifications does not need one. For new permanent apparatus, the city says it cannot issue a building permit without proof of insurance and proof of workers' compensation coverage, so ask any contractor to show both. National Grid also advises an annual check by a licensed professional heating contractor, so ask about licensing too. Get the scope of work in writing and ask who will pull the permit if one is needed.
