All heating systems are ran at the highest setting of the thermostats for at least 30 mins. and checked for signs of improper operation, CO and combustible gases at room vents.  Then the thermostat is turned off and then the system restarted and checked a second time. We have found heating systems that are short cycling because of cracked heat exchanges, faulty regulators and bad temperature sensors. Gas heating systems are checked for proper drafting and venting. After thousands of inspection we have become regarded at top in our field in HVAC inspections.

During two other pervious inspections of this property this was missed by the other inspection company and an Licensed HVAC company.

Have a question?

Ask the inspector

The homeowner had been suffering from carbon monoxide poisoning off and on since 1999 and no one had been able to determine the problem.  The wind turbine and roof air currents have caused the gas vent stack to back draft gases from the heater. This was repaired for our client and the seller was shocked that we were able to troubleshot the problem so easily.

A closer look and some expertise is needed.

LOOKS OK, right!  No, even though the burner itself appears to be in good condition, the rusting flakes in the bottom of the compartment caused us to closely check for combustible gases while running the heat cycle; we found that the unit had indications of a cracked heat-exchange. This is a health risk. The unit was replaced by the seller for our clients.

Piled rusting in bottom of burner barrels, we found high CO gases at room vents.

Electric heating system elements.

2 of the elements have been burnt open and not providing any heating. We were able to predict this by  taking temperature readings and running the system for 20 mins.

Heating systems are a big concern, and should be examined closely by one of our professional inspectors. We are not just looking to see if the heating system is heating the structure as many other real estate inspection companies do.

We tested and inspected this furnace for our client and found it to show all indications that the heat exchange was cracked.  Our client called us back and told us we were right and that we saved them over $2000.00 in repairs that they had the seller pay for before they closed on the property.
