Heater Repair

Heating repair and upkeep is important everywhere to be sure, but heating repair in Buffalo, NY is truly a priority for all involved. The winters do get very cold and can be quite uncomfortable, so having everything working to peak efficiency is vital and will ensure good times and good health when Mother Nature does her thing! The great news for those in the area is that Zenner and Ritter are there to make certain everything is functioning properly and efficiently, just as they have been for the past century or so.


During maintenance, the heater will be opened up cleaned, inspected and serviced properly. All moving parts will be lubricated and thermostat tested to ensure it works. Electrical connections and every other part of the system will also be checked. The burner will also be cleaned and adjusted accordingly to ensure it burns fuel efficiently. After the maintenance, you can expect the heater to operate much more efficiently, have improved performance and break down less often.

Heater Replacement

Heaters should be replaced every 15 years, or as specified by the manufacturer. It does not make sense to continue using a heater that has already exceeded its life expectancy. This is because it will consume more energy than it needs, malfunction every now and then, fail to meet your space heating needs and release a lot of dust into the house. Ideally, you should have the heater replaced before, or when, it attains its life expectancy.
