In Arizona, obviously, the heating season is a lot more mild than the summer months are. That doesn’t mean that you shouldn’t worry about an inefficient performance from your heater, though. You don’t want to be paying more than you should have to in order to heat your home, even if you aren’t doing so as much as you cool your home in the summer.
You should also keep in mind that heating inefficiency may be the result of problems that also affect your air conditioning system. If you have air leaks in your home’s thermal envelope, for instance, you are looking at year round inefficiency. Finding such leaks is the first step in resolving the problem, which is why you may want to schedule a blower door test in Phoenix, AZ.
