Most issues show clear warning signs.
Heat pumps are reliable, but like any system they need occasional repair. Common problems we fix include:
Many heat pump problems are preventable with an annual tune-up, which keeps the system efficient and catches small issues early. When you do need a repair, we give you honest advice: if the fix is straightforward and the system is relatively young, we repair it; if the unit is near the end of its life or a repair costs a large share of a new system, we will lay out replacement options too. A quality heat pump typically lasts 12 to 15 years.
