A

A bad or worn condenser fan motor drastically reduces efficiency and can overheat your condenser causing very high pressures!

31
Q

Why should I replace my condenser fan motor, how long do they last?

A

Life varies with maintenance – If the coil is plugged and the motor is over amping trying to draw air through the coil It may overheat or prematurely seize up.

32
Q

We need to replace your contactor because?

A

A bad contactor will cause high energy draw to the equipment and can cause the equipment to run very rough, and melt wires. Without strong contacts the equipment will not run right.

33
Q

How often throughout the life cycle of the equipment is replacing the contactor recommended by the manufacturer??

A

Contactor replacements vary with usage. It is engaged every time the unit wants to come on and so the more the unit is used the worse the contacts will be. It is recommended replacement at 10 years, but varies with usage. Short cycling will reduce life expectancy of contactor - this is why maintenance is important.

34
Q

We need to clean this condenser coil because..?

A

A condenser that is leaking or operating with high head pressure due to being plugged/dirty drastically reduces your equipment efficiency and puts your compressor and other major components at serious risk!

35
Q

How often throughout the life cycle of the equipment is a full condenser coil teardown recommended by the manufacturer??

A

The condenser coil should be pulled apart and cleaned every 4 years in order to maintain a good temp rise through the coil. However if regular annual washing has not been done it may require it sooner.

36
Q

What happens with my bad Pressure relief?

A

Your pressure relief valve is a safety device and if it is defective or plugged with debris it is important to replace it immediately. It is against code to have an active pressure relief device that is bad and is extremely dangerous.

37
Q

How often should pressure relief valves be tested and when should i replace it?

Q

Surge Protector/
ECM Smart motor Protectors

A

-All SMART equipment systems are equipped with microprocessors just like computers. All computers and SMART systems have a weakness for damage from surges or brownouts that are not warranty. Computers are worth less than SMART HVAC systems and generally computers have surge protection power bars!

-Equipment surge protectors are multi-use/permanent solution with a $7500 lability warranty if installed and damage occurs! ECM Motor Protector protects only the motor but they do make the motor nearly “fail proof”. Surge protectors protect everything that is SMART – Thermostat, Inducer, Gas valve, Inverter boards, ECM compressors, etc.

-ECM motors are SMART MOTORS and run cool so their only weakness are power surges or brownouts. The actual motor failing is extremely rare, but we have replaced MANY non warranty modules. Testimonial

55
Q

5” Filter Rack

A

Do you see this blower wheel? This should not be this dirty. Your furnace is filling with dirt and dust. Your blower is set to 400 CFM per ton and it could be moving more like 300 CFM. This is 25% less efficient! You should be here on the Factory Recommended Services table but you are here. If this continues it could severely damage your furnace & AC. A bad blower will… (refer to blower part Q card)

We are permanently solving this in order to prevent unnecessary spending on cleaning…. Teardown costs 50% of a permanent solution. A teardown is not a permanent solution and will need to be done again. 5’ cabinet will also last forever and filters cost less annually. This filter is 5 times as big and can be changed less frequently. We have to change filters on time every time!

56
Q

Bypass Humidifier

A

Are you comfortable in your home? The humidity levels are very low and this is a problem. It shouldn’t be that low, so I’m surprised that you’re comfortable. Your body is 60% water and your house is 30%… What do you think this does to your body? It’s like a frog in an terrarium with low moisture levels

Low humidity can cause hives and make eczema 10x worse. When humidity is too low there are also risks when it comes to your property, wood floors etc. Also people set temperatures warmer in heating to compensate because we feel colder with dry air leading to more than 5% increased cost in utilities.

This is a permanent solution that will last for 20 years

57
Q

Flame Rectification Sensor

A

This will result in more damage if not replaced due to short cycling. Like starting your car over and over, it is damaging to your engine and uses a ton of fuel. This takes years of life off your equipment from starting over and over.

Its not if its when. At some point flame sensors get weak as they are sensitive due to them being a safety and must fail safe.

58
Q

Universal Ignitor

A

The ignitor is continually getting red hot and then cooling, creating stress on the element eventually causing it to crack.

The ignitor is constantly in the flame when burners are lit causing carbon build up creating more resistance causing it not to be able to reach 2400f.
