HVAC Equipment Fault Detection

Properly sized HVAC systems should provide your living area with adequate air at a comfortable temperature and last for many years, but there are many HVAC systems that are poorly operated or maintained by the owner and can contribute to poor indoor air quality and problematic mechanical systems. I am able to thermally scan for problem areas within your HVAC unit. Temperature variations found during an infrared HVAC inspection will indicate even the smallest of problems, subsequently averting any unscheduled down time or excessive damage to your mechanical equipment. The thermal patterns of HVAC motors, pumps, fans, bearings, compressors, heating elements, humidifiers, etc. can be analyzed for overheating, faults, and any decrease in efficiency. Fatigue and stress concentration in HVAC components can be easily detected and verified along with any air conditioner compressor leaks, if equipped.

Another issue I continuously encounter in most HVAC units is the large number of supply and return ducts that are leaking excessive air at the connection seams throughout long runs and at the supply register connections. This is due to improper or shoddy installation of the duct work. According to national surveys, duct leakage in residential systems typically amounts to 20% to 40% of the conditioned air that is suppose to be delivered through the duct work. That's a lot of wasted energy dollars that can be easily corrected, once I locate these breaches.

There are also many vent connector flue leaks that go undetected, which could cause a deadly carbon monoxide build-up. By utilizing my infrared camera while performing your HVAC inspection, I am able to locate the HVAC inefficiencies that can normally go undetected in the course of my standard visual inspection, simply because these hot spots are invisible to the naked eye. I will be able to point out where these defects are actually located and then compile this information into a formal Infrared HVAC Report which will include descriptions of the defect with side-by-side digital and infrared photos. Don't allow your heating and A/C system to become problematic when you need it most. An infrared inspection of your HVAC unit will detect minor issues before they become costly repairs.

You're unable to visually observe hot spots, but infrared imaging will detect every surface temperature.

Here's what my clients say about me... (Press F5 on your keyboard for additional testimonials)

 

Dave also does basic home inspections but we hired him for his home infrared scan service to find out where we have cold leaks in our house.

Dave did an excellent job. Responded to calls quickly. Arrived on time. Was very thorough. The best part is that he sent us an incredibly comprehensive multi-page report of his recommendations and pictures he took of every area of our house showing just wear the cold leaks were. He suggested the best ways to address each area. I think he provides a very valuable service to homeowners.
