Like a central
air conditioner, a heat pump also has an outer unit. Like any other HVAC system
and its components, this outer portion of the heat pump also need regular maintenance
and repair. While the inside unit is rather simple to maintain, the outer side
is much more difficult since it is not that accessible. To help you with the outdoor
Heat Pump maintenance
and repair, I decided to share some pointers.
Tip 1 – Clean the Compressor and Coil regularly
The outer unit of
a heat pump consists of several intricate components. Each component has its own
significance in the overall process of heating. However, the compressor and the
coil is perhaps the most important among all and that’s why they need to be
cleaned and maintained regularly.
You can do this
by taking the outer part apart and cleaning with proper tools. Make sure to get
rid of both the greasy substance as well as the dirt and debris.
Tip 2 – Wipe the fans and get rid of molds or dust and debris
Since the heat
pump cannot be operated without this fan, it is important that you take good
care of the fan. And by taking care of the fan, I mean cleaning and wiping the
fans every once in a while.
Note that often times
the fan can be infested by molds. So you need to take care of the molds and the
dirt debris all at once.
Tip 3 – You can use vacuum cleaners
or blowing air to the components especially the fan is not enough. The big chunks
or the extremely tiny particle are hard to get with a wipe so in that case, your
vacuum cleaner will come in handy.
When you can’t get
the tiny particles with wiping or blowing, put the vacuum cleaner in between
the fans and suck out those particles.
Tip 4 – Check the pipe insulation
is very important and sometimes the insulation can be compromised. When this
happens, both you and your HVAC system, more particularly the heat pump is at danger.
So, you need to attend to the compromised insulation and if the condition is even
worse, you might need to change the insulation entirely.
Tip 5 – Balance and Adjust the heat pump
Toward the start
of each heating season, set one carpenters' level over the actual highest point
of the metal cabinet & then check the level from front to back and from side
to side. In the event that the unit is never again level on the pad, you need
to lift the pad back to level by slowing prying it up with the pry bar or a bit
of 2-by-4. Develop the ground under it with rock or crushed stone.
Tip 6 – Don’t forget to do the air duct cleaning
When you go with the
outdoor air conditioner services and repair, you should also get the air duct cleaning done because you might not even remember to
do that later.
Tip 7 – Call HVAC experts if you are having trouble
Lastly, not every
outdoor heat pump maintenance and repair situation can be handled by everyone.
That’s why it is best if you can call on HVAC experts when something goes over
your head. Don’t try to be the smart guy who tries to be the all-knower and end
up with a broken AC.
But before you call
HVAC specialists, you should know how the heat pumps works. It will help you
better understand the AC repair
How does a heat pump work?
Basically, it works like a refrigerator. That means, in
general, it has a refrigerant-like substance that collects heat and turns into
liquid from the gas. Then it releases the heat and turns into a gas. The heat
pumps can also reverse the cycle.
In summer, a heat pump collects heat from a high-temperature
area and then exert that heat into the outside air, just like a central
air conditioner. But in the winter, it reverses the cycle. Then these
heat pumps take the amount of heat from the outside air and push that heat into
The heat pumps mainly have two primary sources from where
they extract the heat. These sources are ground and air. According to the
sources, these heat pumps are named. Heat pumps that use air are called Air-Source
Heat Pumps and the ones that use the ground, are called Ground-Source Hear
Pumps and sometimes Geothermal Heat Pumps.
