Depending on the square footage and the current temperature, you may want to program your thermostat to start heating or cooling your home an hour prior and turn off an hour after your preferred temperature.
Also, to avoid having the havoc of ever changing temperatures, you may want to look at programming the thermostat at a constant temperature throughout the day and evening.
Replace the filter before the start of the heating season.
There are many filters to consider, you may want to look at a filter that is pleated for best results and with a 5 start energy cost index.
Ensure to ask what is to be done in the annual service tune-up.
For a routine maintenance visit, homeowners should expect to pay around $100$150 with filters available for a fee.
A competitor’s service technician could charge $60 per hour for a HVAC repair from Craiglists and be a great carpet cleaner. Qualified HVAC technician could fix an air conditioning system for $150 per hour and be a great value. How can this be? A $150 per hour technician should perform a complete and thorough diagnostic procedure. Everything should be cleaned and tuned and a professional repair made, answers your question. That’s worth two hundred bucks. A sixty dollar an hour parts changer who takes longer than he should and looks like he’s there to clean the house ,tar the roof instead of repairs to HVAC system is no bargain. A tech at $60.00 per hour is still a cleaning tech.
Think about it … Refrigeration guys who had gone through proper training, exams & license would never do this
