2023 PCSA Heating renewal Heating Maintenance. System is heating efficiently at this time, temperature rises good, filter has been replaced, and all hoses and drains are clear.I did not see a carbon monoxide detector anywhere in home, if there isn’t one I would recommend getting one. We can provide, install and test one if needed for home. Hot surface igniter is also showing signs of potential failure. If desired, we can replace this part as a preventative. Other than this, system is heating well.
