Get your AC ready for summer!

Air conditioners are the most crucial part of the home or business during the summer months. It is imperative to get ready for the coming summer temperatures. In this article I will go over a few things to look at on your Air Conditioner to get your AC ready for summer.

Capacitors are one of the most common things that go bad during the summer temperatures. You can prevent this by testing the capacitor Microfarad level by using a multimeter that is equipped with the feature. I recommend testing the indoor fan capacitor and outdoor fan capacitor. You can test the capacitor by removing one side of the circuit on the capacitor. Put the test leads of the multimeter across the top prongs of the capacitor. It should give you a microfarad reading of what the capacitor is rated for. So for example if you have a 12.5 microfarad capacitor. It would be most likely rated for plus or minus 6%.

12.5 x .06 = .75 So the capacitor shouldn’t be lower then 11.75 microfarads. Let’s say you have a capacitor that tested 11.13 microfarads. Then you would want to replace the capacitor with one that is within the range.

Most home AC’s use Dual run capacitors. These are two capacitors that are built in one. One is used to run the Compressor, and the other is used to run the outdoor fan motor. Capacitors are used in a electrical circuit to boost the amperage. So they can hold a charge when removed from the circuit. It is important to discharge the capacitor by putting a piece of metal between the sets of prongs on the top of the capacitor. I like to use a screwdriver.

Fan motors should be working without any excessive vibrations or bearing sounds. It is important to be careful of bending fan blades.  It is hard to repair a fan blade when a fan blade gets damaged. It is easier to just replace the fan blade with the exact same model of blade.

Condenser coils get dirty over the years with dust and other things. You can spray off the coils with a garden hose to help remove the dirt. I recommend using a condenser coil cleaner if the coils are really dirty. Most common spray on cleaners will require water for the condenser coils and no water required for the evaporator coils. Since there is a build of condensation on the evap coils during operation that will rinse the chemical cleaners off.

Most drains will get clogged over time with dirt, animal hair, and a sludge build up. I recommend checking the drains coming off the evap coils. You should clear the piping with water or compressed nitrogen if there is a clog. I like to use the drain dawg kit that has a long hose attached to a nitrogen regulator and tank.

Steps to winterize

Winter is coming!!! Now is time to get your systems ready for the colder temperatures if you haven’t done so already. In this article I will show you steps to winterize your units.  Many people don’t really think about their AC or evaporative coolers much after the summer months, but if you continue to do necessary maintenance steps. Then you can help prolong the life of your units, and that will help you save a few bucks eventually.

Most units in Arizona that I come across are heat pump units. Meaning that they are built a special way in which they have a reversing valve. That will cause the hot air to blow across your indoor (evap) coils as opposed to usually leaving your outdoor (condenser) coil. Heat pumps usually are enough here in the desert since we only near freezing temperatures in the winter. Some heat pump units will have electrical heater strips as an addition to the heat pump operation. I have attached some examples of reversing valves below.

There are many other types of heating systems. Another common set up is a gas furnace. They are sometimes built into package units. They are easily identifiable with their need for a gas line hooked up to the unit. You will want to make sure the units engage when you call for heating on your thermostat. If you have a gas system you will want to make sure the gas valve is open. The thermostat should engage the furnace. Which will cause gas to engage and get lit by the igniters. Electrical heat strips should engage if they are equipped. If you have a hydronic system. You will want to make sure the water pump engages and flows the water through your coils.

Once engaged, your heating system should produce heat out of your vents in your rooms. I recommend checking this before the winter, and it’s a time you really want to use it.

It is a good time to inspect the life of the other working parts of your evap cooler when winterizing it. I usually will replace the pads and possibly the belt at the end of the season if they have mineral build up on them. When winterizing I recommend shutting off the water supply, and removing the drain stem to remove the water from the pan. You can keep the fan plugged in if you would like to use it to bring in fresh air still. This is a good practice to follow because freezing water can shorten your machine’s life.

DIY Mini Split AC! The benefits of the newest and easiest way to add HVAC to your existing home.

Mini split sales have been increasing around the world for a few decades. Their popularity is finally getting noticed in the United States. The more I have came across them as an HVAC technician. The more I have been impressed of their quality. They can be pretty simple to install in comparison to the more traditional package and split systems. Which usually in turn means less labor and less costs.

There are a few things to take in consideration when deciding on the mini-split system. First thing is to consider what you will be needing the adding cooling for.  There are 2 types of cooling. The first is comfort cooling, which most systems operate in this fashion. They tend to only care about a specific temperature in mind and tend to run far less than the other kind. Process cooling  is the other type. Process cooling is used for rooms that build large amounts of heat from a variety of sources. Many data centers and grow rooms use process cooling systems due to the amount of heat needed to be removed from the environment.  Process cooling systems tend to be a little bit pricier than the more traditional comfort cooling systems, but they are built with higher quality parts to withstand the abuse of constantly running.

Next you need to decide on how much cooling you will need. For comfort cooling systems most people use the rule of thumb. For every 500 sq ft of space you should have 1 ton of cooling (12,000btus). This also depends on how tall your ceilings are for the room. If you are using a Mini-split for a grow room. I have attached a helpful link to help you determine the btus and cooling you need.

It is also important to keep in consideration how well your room is insulated. Proper seals around doors and windows can keep your system running less. Which leaves your electricity bill lower.

Many mini split systems use far less electricity than their bigger counterparts. It is important to make sure there is enough room on your electrical circuit panel too.  This is not that easy to determine for the DIYer so I recommend getting an electrician or HVAC guy to help if you need more assistance.  I am available for installs and servicing your mini splits with proper compensation. I have attached a few mini split systems that I would recommend getting for a comfort cooling setup.
