Theres a freeze coming to Houston tonight and tomorrow. Here's what you need to do: 1. Don't overuse the furnace. Set it to something manageable so it doesn't break down on you trying to keep up. 2. Replace your filters before the freeze so that the unit can breathe and work at its peak performance without dust clogging the system. 3. Keep all doors open inside the house to let the heat move freely! Now you know, stay warm! #hvac #ac #airconditioning #diy #homeowner #homeownership | LMH Services
