/Users/debraturak/Desktop/air-conditioning-system.jpg. In reviewing the image I learned more about the makeup of the air conditioner system. This will come in handy when doing my inspections. I will still need to watch more videos on inspecting the air conditioning system. All done
The first thing I did was look at the overall condition of the furnace. The filter appeared to be changed lately. After removing the front of the furnace I checked for any type of burning to the outside of the chamber, nothing abnormal occurring.
There is a ventless gas heater in the sun room. This type of heater vents combustion products directly into the living space. These units are not designed to be a primary source of heat and should only be installed and operated in complete accordance with the manufacturer’s recommendations. It is also recommended to have a carbon monoxide detector in this room if operating this unit.
15 tools every homeowner should own essay:
The following tools are essential for every homeowner to own. A plunger for clogged sinks or toilets. A combination wrench set in standard and metric units. Slip joint pliers, adjustable wrench, caulking gun for sealing cracks and gaps in caulking around piping, and seams along the bath tub or shower. A flashlight, tape measure preferably 25 feet in length, and a hacksaw for cutting metal objects such as pipes. These are just a few of the 15 tools every homeowner should have for diy projects around the house.
This is a picture of a supply and return air plenum. The way this work is that the cool air is drawn in through the return plenum, where it enters the heat exchanger and is drawn up the where it exits the supply plenum and into the registers.
I chose to read the article that talked about how to inspect a garage. In this article Kenton Shepard state that he was entering a garage that had been built by questionable builders. So as her was making his way through the inspection he found several defects including, substandard fasteners for the truss hangers, undersized truss hangers, and plywood gussets on the trusses which is a sign that alterations had been made. Also there where trusses that where resting on interior walls.
Adjustable steel columns are an acceptable way to support a floor above. Columns need to be a minimum of 3 inches in diameter and covered with a rust inhibative paint. They need to be secured to the floor or footing and secured to the beam above.
this a picture of a furnace air filter that just has ben changed out for summer time so the A/C unit does not have to work so hard to cool the house because if the furnace filter is plugged up you will have higher electric bills because the efficiency of the A/C unit will drop do to less air flow across the evaporator coil and you might freeze up your coil so change your air filter on a regular basis
The hydronic heat system i have learned that you have to have the right components in the system or you will have problems with it so when you are looking at the system you need to make sure that it has the T & P valve and the expansion tank if the tank is missing you will have your T & P valve going off all the time.
A data plate contains a great deal of useful information, both to the installer and the inspector. The data plate states the manufacturer name (Lennox), the product type (heat pump), various pressures and voltages, and the maximum fuse or breaker amperage (20). The model and serial numbers are also on this tag which can be useful for date of manufacture estimation and recall information.
I chose to read “Asset Protection for Inspectors”. The article describes several methods to legally protect your personal and business assets in case of a lawsuit. The simplest and primary is to purchase and maintain liability insurance. This generally covers errors and omissions.
This picture is of an outside coil. The manufacturer is Standard and it is from 07/2002. The unit is at the end of its expected life. This unit was also grown in by vegetation and the suction line had no insulation on it.
I read the article TPR Valves and Discharge Piping. Amazing how such a small thing can be so vital to safety. I have heard of hot water heaters exploding but have never seen the results of one. I think that the article had some very good tips on what to look for in an inspection.
Condenser units appear serviceable. Suction lines are properly insulated at time of inspection. Fins appears serviceable. Unit could not be tested at this time. Ambient temperature was below 65 degrees. Both units appear to be level at time of inspection.
I have learned how to recognize the different types of furnaces and how the are too be inspected. I also learned about carbon dioxide. Learned also how condensation is created in each type of system. Learned that i was a few tools short for inspecting HVAC units.
ICG Condenser unit has insulation missing from the suction line. The suction line must be fully insulated and not in contact with the smaller liquid line. The unit itself is no longer being properly supported by the foundation block provided. This could lead to movement of the condenser unit and potential for breakage of the suction, liquid or electrical supply lines entering or leaving the unit.
As we can see in this HVAC tag picture, it is a relatively new unit. We can observe the information required to know the model number, capacity of the HVAC, and to date it also. According to the building center website i can accurately say that this unit was manufacture on 05/2006.
In the image i observed titled compressor on the HVAC album; i was able to observe and lear the function of a compressor. I learned that it sucks air at 70 psi, and discharges it at a much higher pressure of 225 psi after compressing the air. This image was very informational.
Utilizing the AC image gallery, I have learned how the AC system works. Refrigerant gas is compressed and therefore heated in the compressor where it is turned into a liquid. A fan inside the compressor unit is activated to pull outside air through the condensing coils. From here it is moved through the liquid line to an expansion valve allowing the liquid to reduce the pressure and begin to boil off, before entering the evaporator where return air passes over the evaporator coils cooling the air before being distributed through the dwellings duct system. From the evaporator coils the now gas returns to the compressor to start the cycle again. Condensate produced in the evaporator will collect in the condensate drip pan which should then drain out of the pan to either the floor drain or another drain pipe connected to the main DWV system.
