The heating and cooling systems should be inspected and serviced on an annual basis. Ask the seller before the close of escrow for any and all documents concerning regular maintenance and service, including any warranty paperwork, if applicable.
Recommend obtaining from seller well before close of escrow any documents concerning regular maintenance and service. If it cannot be proven that any heating and cooling systems have been inspected within the past twelve months, recommend a safety check by public utility or a complete system evaluation by a qualified heating and cooling specialist. Utility companies typically, but not always, provide a free safety check of all gas-using appliances. Note that utility companies have the authority to shut off gas to the residence if they find problems. Such action could cause inconvenience to the Seller and might possibly delay your escrow closing date. If there is a cooling condenser sitting somewhere outside your home, and your furnace is located in the attic, there should be some additional systems in the attic to help with safety and maintenance. The best installation will include a primary condensate drain line with a trap on it, a secondary drain line, and a drain pan. An optional, but very useful, device is a float switch installed in the drain pan that will shut off the furnace if the drain pan fills up with water. |
Main condensate drain line, trap on main line, secondary drain line, and drain pan. The exterior cooling condenser will operate most efficiently if it is clear of any obstructions. Under these conditions, cooling capacity will be diminished.  
Problems with cooling condensers: Vegetation and Designer housing. Heating and cooling systems are dangerous because of the gases and fluids that they use and create during operation. Make sure that you have your heating and cooling system inspected annually by a licensed heating and cooling professional. |
