This is a Trane XR95 dual fuel system, high efficiency furnace that was installed in 2011. The dual system consist of a gas furnace and a heat pump. While inspecting the air filter the access panel was located on the bottom of the furnace and was easily accessible and had a good quality metal air filter in use. It was found to be clean and in good condition. ]
The air handler and exchange units are combined and in the basement. The system was turned on and operates as intended. It is in good condition and shows no abnormal signs of use. The serial number: 4206X39171 on this unit reflects the 42nd week in 2006.
AFCI TESTERS:
These devices are a great compliment to the utilization of the Test button on each AFCI outlet. These devices mimic an arc which simulates a failure of the AFCI outlet, however they are not fail safe and can produce false positives. These false positives may present the outlet to fail the test while they are in-fact properly functioning.
This is a Lennox, Electric, Heat Pump. MFG date Aug 2013 (determined by referring to “buildingcenter.org” ). This system responded and achieved an acceptable differential temperature of 20 degrees F. at the time of inspection.
I choose to do a short essay on Garage Inspections. While looking at the home inspection comments and pictures I learned that the trusses should be setting on the proper bearing points to support the roof. Anything different can cause a collapse of the structure especially when it is under load in the winter time with snow fall. I also learned that any wooden gussets that are added to the truss connections could very well indicate there has been a alteration of some sort and should be called out on a report. Another key point that I learned was screws that are used in fastening are prone to fail under applications if not used in the manor they were designed for. In closing looking at all the trusses in a garage and the arrangement of how they are put together as well as where they are setting to support the load is very important to the life of any structure.
One of the things that can serious effect a cooling systems efficiency is dirty filters. even with out opening up the filter compartment there are tell tale signs that the homeowner should look for. One of those is dirt accumulating on the exhaust vents as seen around he edges of the diffuser shown in the attachment. Now this could also be an indication of poorly sealed joints in the duct work as well. Filters need to be changed on a regular basis, depending on use and environmental conditions. Inspections by a qualified HVAC company although have a yearly cost impact to the homeowner, but can be a huge cost savings by preventing unnecessary repairs.
Protection of your system components can be a cost savings and add years to the service life of you units. During the winter months or off season for cooling needs, the outside condenser should be covered to protect it from the elements. Cleaning to make sure leaves and other objects are not in the grills or vent, and then it should be covered to reduce snow accumulating in the top of the unit. The homeowner should be made aware to make sure the unit is off prior to covering. Having a system check prior to stating during the next cooling system will also keep the unit running efficiently.
Hey guys I just finished up the HVAC Inspection Course. This HVAC course contained a lot of very good information. I would certainly recommend this course if you have not already taken it.
This A/C unit is in good working condition and was serviced in the last week. I was intending to de code the s/n but as you may be able to tell it has faded out.
I inspected the furnace in this one. It is a good man natural gas doe flow high efficiency furnace. I can tell it is high efficiency by the exhaust is pvc and by the decal on the furnace. The filter was clean and the housing was very clean. There was a gas shut off valve right next to the furnace.
This is an image of a a/c unit condensing unit. The unit is in satifactory condition at the time of this inspection. The unit has no rusty areas and is mounted on a proper mounting surface, it is level and the electrical disconnect was in good condition and mounted within proper distance of the unit. The outside temperature was above 65degrees so the system was checked for proper operation. The unit performed in a satisfactory manner and was holding a temperature of 78 degrees as set on the thermostat.
This is a picture of a condensing unit. The insulation on the suction line has deteriorated at the end. This will allow the line to absorb more heat from the environment before passing through the condenser coil, reducing the efficiency of the system. Its hard to see, but there is also a kink in the suction line before it 90’s into the condenser unit. This will also reduce system efficiency by restricting refrigerant flow.
Read an article on central air conditioning system inspection. It discusses general maintenance a homeowner can perform to keep the cooling system in good shape. One is too clean the condenser coils and then cover the unit to keep it clean until the cooling season returns (secure the power off course). Homeowners should check and clear if necessary clogged primary and secondary drain lines. They should check and replace air filters on a monthly basis. And during the heating season they should secure and cover cooling registers to keep pests out and heat from escaping.
Flat Plate Solar Water Heater. Damper open and close properly. Seal and glazing in good condition. Wiring shows signs of degradation. Recommend further inspection by certified technician.
There are 3 types of solar thermal systems. The inspector should identify which system is in use. Be sure to inspect damper if one is present. Check TPR, check for mineral deposits and for any proof penetration. Solar thermal systems are a great option but should be checked periodically for functionality.
Pictured is a Garage entry door. This is not the main egress door of the residence. It is a 1-3/8" steel honeycomb door. The door has an automatic door closer. The door swings outward with clear travel and lateral space with a 5" step-down to the garage floor. There are no steps or landing.
Receptacles for Decks & Balconies
Deck receptacles must be spaced no greater than 20’ apart on large decks and balconies/ porches. The receptacles must be rest securely on the supporting surface to prevent moisture intrusion. A weatherproof enclosure must be present on all 15 & 20 amp, 120/240 volt outlets. All exterior receptacles must be GFCI protected.
10 Easy Ways to Save Money & Energy in Your Home.
Making a home more energy efficient can save the home owner money. It increases the comfort level in a home and reduces the impact on climate change and reduces pollution.
Ways to help make a home more energy efficient include: Installing ceiling fans, setting thermostats appropriately, installing tankless water heaters, adding curtains for insulation, replacing incandescent lights with LED’s and CFL’s. Also, cooking smarter to use less electricity and installing efficient shower heads and toilets, insulating doors and windows and even changing the way we do laundry can help a home to become more energy efficient.
This is the label from an American Standard Gold series heat pump. The unit was manufactured in 2014. Using the systems normal controls, and after checking the temp. split with a laser therm, I reported that this system seems to be within normal operating parameters on the day of inspection.
Pilot Lights
Study show a standing pilot light can burn $7.50 to $18.00 worth of natural gas a month. This is an energy waste,
In a six month period a normal pilot light can produce 450 pounds of carbon dioxide. Carbon dioxide is a greenhouse gas.
HVAC
This is a photo of the outdoor heat pump, compressor, fan and condenser unit. The Unit was functioning properly. It feeds an attic installed horizontal air handling unit and evaporator. This a common central an forced air heating unit found in Florida an most south east states. because of the winter temperatures. I was able to utilize Bens advice on determining the age of the unit. I went to buildingcenter.org website looked up the unit S/N by manufacturer and was able to tell the unit was manufactured in 2005. I also recommended that the bottom of the unit should be kept clear of foliage and debris, there were a lot of fallen leaves gathered around the base of the unit.
