Alex has called in the HVAC Technician to troubleshoot his furnace problem.
Short cycling (the constant turning on and off of your furnace) is a common symptom. An oversized furnace is the most expensive culprit, because it means you need a new furnace but other causes could include a dirty air filter, a misplaced thermostat, a corroded flame sensor and a blocked exhaust vent.
So as a general rule bigger is not better when it comes to heating your home, the on and off cycling is not only expensive on your heating bill, it can take years off the life of your furnace.
When replacing your furnace make sure you contact a certified heating expert to perform a manual J Heat Load calculation. The calculation takes into account many factors including the size of your house, the insulation levels and the local climate.
The most important thing to keep in mind if you’re renovating your house is that if you’re increasing the insulation levels in the building envelope or improving the air tightness it is always better to have your furnace sized after air tightening to avoid the possibility of an oversized furnace.
