Our surveys of local consumers turned up dozens of excellent HVAC services. But not all contractors are cool characters: Several others received poor overall ratings from their surveyed customers.
We also found huge price differences. For example, to replace the ignitor for a Trane gas furnace, our undercover shoppers were quoted prices ranging from $198 to $665. To replace the dual-run capacitor for a central air conditioner, prices ranged from $169 to $750.
For new equipment, to avoid overspending get written proposals from at least three pros—some companies charge thousands more than others for the same install.
Need a new central air conditioner? Consider a heat pump instead. These devices are basically air conditioners that can both heat and cool buildings. New models are extremely energy efficient and quiet and can reduce reliance on furnaces.
For new furnace installs, you’ll have to decide whether to pay extra for more energy-efficient equipment; for example, a highly efficient 98 AFUE gas furnace costs about $1,500 more than an 80 AFUE model. But you’ll recoup the extra cost quickly via utility rebates and lower gas bills.
Don’t spend thousands of dollars upgrading to energy-efficient HVAC equipment without taking other steps to reduce waste. In our “Saving Energy at Home” section we detail 30 ways to cut usage. Many improvements cost little or nothing but will have big effects on your utility bills.
For installation contracts, get performance guarantees specifying how warm or cool the equipment will keep your house, and how uniform the temperature will be inside when outside temperatures reach a specified level. Be sure your contract clearly states the company’s responsibilities on issues like providing an electrical supply and hooking up your equipment to the electrical panel; providing drainage for condensate; enclosing ductwork; and painting and patching holes.
