Winter weather may be months away, but as the nights turn cooler, your heating system should be given a tuneup. Keeping your home’s furnace clean and adjusted can help it run efficiently and help you save money in the long run. Your local utility company may offer free checkups by teams of technicians. Now is a good time to book your appointment, since winter is when appointments become nearly impossible to come by. These checkups will tell you if any repairs are needed for your heating system.
