I’ve been looking into replacing the current gas furnace in my home. The heating system was already in place when I bought the house fifteen years ago. It was not properly serviced and showed signs of corrosion. I have been conscientious about changing air filters and having professional maintenance completed every fall. The furnace has never malfunctioned and continues to operate reliably. However, there are indications that it’s reaching the end of service life. The furnace now runs for much longer cycles, seldom shutting down, and yet struggles to maintain a comfortable temperature. I’ve needed to set a higher setting on the thermostat, and I’m paying far more in monthly energy bills. There are hot and cold spots in various rooms in the house, and an unpleasant, musty odor. I’m forced to clean and vacuum more often because of the higher concentration of airborne dust, and the furnace has become rather noisy. I’m worried that it’s going to fail in the middle of the winter and leave my family without heat. Instead of rushing to get a heating system installed, I’d like to take my time and choose a quality, energy efficient furnace. I’d prefer to schedule installation at a convenient time over the summer. While I’m reluctant to replace a furnace that is still operational, I think a proactive strategy is the best course of action. I’ve already spoken with a local HVAC contractor and scheduled a free estimate. I’m a little concerned by the cost of a new furnace, but I know I’ll save money on much lower monthly energy bills. Plus, we’ll enjoy superior comfort and air quality.
