My furnace lights and then shuts off after a minute. Is that expensive?expand_more
Usually not. That pattern most often points at a flame sensor that has fouled, which is frequently a clean rather than a part, or at a pressure switch responding to a blocked vent or condensate line. All are inexpensive on a unit that is otherwise sound. It is worth having looked at promptly, because the shutdown is the safety control doing its job.
How old is too old to keep repairing?expand_more
There is no clean number, but the useful test is the unit's remaining life against the repair. Under fifteen years with an intact heat exchanger, most single faults are worth fixing. Past twenty, with several major components already replaced, each repair is buying a shorter and shorter run and the money is better held towards a replacement.
My heat pump blows cool air in the middle of winter. Is it broken?expand_more
Often not. Heat pumps run a defrost cycle in cold damp weather, which briefly reverses and can feel cool at the vents before normal operation resumes. If it is short and occasional, that is the system working. If the house never reaches temperature, or the outdoor unit stays iced over for long periods, that is a fault worth a visit.
Should I get the system serviced if nothing is wrong with it?expand_more
An annual look before heating season is worth it on an older gas unit, mostly because the things that matter — combustion, the heat exchanger, the venting, the safety controls — are not things you can inspect yourself. It also finds the consumable parts that are close to failing, which is a much better time to replace them than mid-January.
Can a technician tell me the heat exchanger is cracked without me seeing it?expand_more
They can tell you, but you should ask to see the evidence — a camera image, or the location described specifically. It is a serious finding with a serious price attached, and a reputable technician expects to show their work. If nothing can be shown and the recommendation is immediate replacement, a second opinion is reasonable.
Is a bigger unit better when the time comes to replace?expand_more
No. An oversized system short-cycles, heats unevenly, and wears itself out faster. The capacity should come from a calculation based on your house — its size, insulation, windows and orientation — not from matching the number on the old unit, which may itself have been wrong. Ask to see the calculation.
What does this service cost me?expand_more
Not a penny. Describing the problem and getting called back by local companies is free, and staying free is not conditional on what you decide — there is no fee if you hire one of them. You pay only the contractor, only for the work done.
How many companies will get in touch?expand_more
Two to four, matched to the equipment and the job you have described rather than blasted out to everyone with a van. Only the matched companies ever see your name and number, and the request is not resold to anybody afterwards.
