I do HVAC and other related work. Do you need your furnace checked for function and safety? I'm your guy. I'll identify any potential points of failure in addition to performing a combustion analysis to determine if you're ready for this winter. My price includes looking at the system and giving you a list of repairs that I can perform later or you may use to shop around. I don't have anything to sell besides my service so I'm not looking for much. Thank you.
