You can usually slip the belt on the motor’s (smaller) pulley first and then start it on the blower pulley. Rotate the blower pulley by hand, holding the belt in place but keeping your fingers from getting caught between the belt and the pulley. The belt should slip right into place. If it seems to be too tight or difficult to set in place, it may be necessary to adjust the motor mount to provide more slack.

Given the broad price ranges above, it's easy to recognize that the cost of your furnace repair varies drastically based on which parts need attention. As a result, it makes sense to gain a better understanding of the parts that heat your home, and how much they cost to repair. Repairing or replacing your furnace’s blower motor can cost you anywhere between $150 and $450, depending on the extent of the damage. Heat exchanger repair costs can vary greatly, from as little as $100 for a simple fix to as much as $1,200 for a full replacement. Repairing a furnace igniter will only cost you $300 at most, while flame sensor repairs generally fall between $80 to $250. The average cost to repair your Thermostat will range from $108 to $282.
We know that furnace breakdowns can happen at any time. As a full-time heating contractor, we keep abreast of current technologies and, as a result, our technicians are able to install or repair any heating system efficiently and in a timely manner.

“The manufacturers that built them all agree on this; you should get it serviced once [a year] for heating and once for cooling," says Paul Mills, owner of Air Experts Heating & Cooling in Raleigh, North Carolina. "Tuning it up and checking it out is definitely recommended. Much like a car, if you ignore it, a lot more things break. You [will] extend the life of it and help prevent major breakdowns.”
"Jorge Mondragon was very prompt and did an excellent job replacing my old heater furnace with a newer one. He explained me very well the details and specifics about why I would need a 3.5 ton furnace with the specific BTU given the square footage of my house. I would highly recommend him as he is a sound professional and very prompt in his service."

When a furnace maintenance is performed a combustion analysis should be performed to identify any problems that couldn't be found by a visual inspection. You want to know what the Carbon monoxide level your furnace is producing as well as the oxygen/CO2 levels and stack temperate. The analyzer will also give you a calculated efficiency rating with the information the analyzer receives. You should have >100ppm of Carbon monoxide output during normal operation of your gas furnace. When you have higher numbers or CO numbers increasing during operation their is a problem with the furnace the technician should then find the cause of. This is just a brief explanation I'm trying to get across to those who get their furnace maintained and to those who don't! Check to see if anyone in the company has a NCI certification for carbon monoxide/combustion analysis.
