Capacitor in Air Conditioning — September 25, 2018

Capacitor in Air Conditioning

What is a Capacitor?
One of the most common repairs during the summertime is replacing a capacitor on an air conditioning system. The role of the capacitor is to help start up the motors, such as a compressor or fan motor, in your HVAC system. The voltage from your electrical panel is not enough to start these components and needs the help of the capacitor.

Is your capacitor bad?
The most common symptom of a bad capacitor is if a motor isn’t running or perhaps your outside unit (the condenser) isn’t running. So before you call your local HVAC contractor, you can do a visual inspection of the capacitor. The other method requires a multi-meter that can measure microfarads.

Safety First
Anytime you work on or look at some type of machine, safety is a must. If you have absolutely no idea, call a local air conditioning repair company to help solve the problem. Turn off the power to your outside unit by flipping the breaker to off or at the disconnect. Open up the electrical panel to your outside unit. The cylinder like object in there is your capacitor. If the top of it is domed, it is bad and will need to be replaced.

Ductless Heat Pump…Why you just might need one — September 24, 2018

Ductless Heat Pump…Why you just might need one

Ductless Heat Pumps (aka Ductless Mini-Split Systems) have become the new efficient way to heat a home, especially for homeowners with all-electric homes, who rely on baseboards or electric wall heaters for home heating. The reports of efficiency and quiet operation have generated so much interest with homeowners and businesses, we’re often approached by folks who wouldn’t necessarily need a Ductless Heat Pump System.
Since they’re relatively new to our market, the level of consumer knowledge about Ductless Heat Pumps is limited when compared to other traditional heating systems like gas furnaces or boilers. As a result, we get many questions from customers trying to determine if this type of system would be a good solution for their home. These questions range from basic application, to how they operate.

So let’s start with the basics. What is a heat pump? A heat pump works just like an air conditioner. In cooling mode, (yes, they provide cooling too) a heat pump moves heat from inside your home to the outside. Unlike an air conditioning unit, a heat pump can be used to heat your home, and do it efficiently. A ductless heat pump does this by reversing the process it uses to provide air conditioning to your home. It collects heat that exists naturally in the ambient air outside and delivers it into the home. The heat that is being “pumped” out for cooling, or in for heating the home, travels through pipes containing refrigerant.

Here Is The Efficient Setup For The Air Conditioners That Are Portable — September 22, 2018

Here Is The Efficient Setup For The Air Conditioners That Are Portable

The suppliers of the portable air conditioners make the setup easier. What you only need to do is to roll the device and turn the startup. Even though it is nearly so simple, there are several suggestions to make your portable air conditioning run more effectively. See Watts Pex 1000 feet.

Making from the Hoses

There is a saying that you do not have to “create” cold. The absence of heat along with the presence of cold really cold is. All the stuff that you just identify that make the things cool simply removes the heat energy and place it from the other place.

Portable air conditioners vent heat via a hose just like normally the one over a clothes dryer. If your hot air blows on the same room you are just burning electricity for no reason. You might be going to have to install it the hot air outside. One option is in a drop ceiling where your building’s main HVAC system can handle it. Another option you could do would be to run the exhaust out of your window. See Tekmar 256 Boiler Control.

The air is definitely nothing, right? If you are intending to wave your hand upon it, you will feel that there is no resistance. This will make people think air can flow anywhere so they don’t have to concern yourself with the way the hose is positioned. In fact, air comes with mass plus it does develop friction within a tight turn. Portable air conditioners must move the massive level of air so if ever you will find there’s a little bit of resistance then this efficiency will likely be greatly affected. Keep hoses straight hence the air can flow freely.

How Air Conditioning & Heat Pump Evaporator Coils (Cooling coils) are Cleaned — September 21, 2018

How Air Conditioning & Heat Pump Evaporator Coils (Cooling coils) are Cleaned

Evaporator coil cleaning often requires cutting refrigerant lines, removal of the coil and other components for cleaning, and reinstallation, pulling a vacuum on the refrigerant lines, and recharge with refrigerant. Such service and repair may involve significant expense, although there are some “in place” cleaning methods using foams and sprays that are a simpler procedure. See DIRTY COIL CLEANING PROCEDURES for details of this topic.

FROST BUILD-UP – Frost Build-up on the Evaporator Coil in an Air Conditioner
The ice or frost formed on a cooling coil in an air conditioner air handler unit is usually caused by an improper refrigerant charge, possibly by inadequate airflow across the cooling coil, or by a thermostatic expansion valve (TEV) or other air conditioner or heat pump control defect.

Ice blocks air flow through the coil, thus reducing air conditioner output; if the ice formation is extreme nearly all of the airflow across the coil is blocked and the air conditioner system runs but does not produce cool air flowing into the occupied space.

Frost and ice can also form on refrigerant tubing at other locations, and frost and ice can form inside air conditioning ductwork itself, leading to troublesome leaks into the building.

Cooling problems hitting your pocketbook — September 17, 2018

Cooling problems hitting your pocketbook

Hundreds of homeowners found out that they had attic ventilation problems during the heat wave last week. There are more of them out there, but they don’t know or haven’t figured out that their attic is adding to their cooling problems this summer. Pennies, nickels, dimes or even dollars are being lost to poor attic insulation every day. You may not notice that your cooling bills are larger than they should be, but you do notice when your air conditioner doesn’t keep up on an extremely hot day. Flip a coin or venture a guess; is your air conditioner dirty and in need of servicing or has your attic developed an insulation or ventilation problem over the past few years?

A/C Can’t Keep Up!
The wake up call for a lot of Chicagoans is when their air conditioner doesn’t keep up on a particularly hot day. More often than not this problem can be fixed. With a phone call to a local HVAC or attic ventilation and insulation professional, you can get your home cooling well once more and save money on your electricity bills the rest of this summer, and winter, and the next summer and winter, and simply put, fixing an attic ventilation or insulation problem saves you money for years to come!

Do it Yourself or Go Pro?
“Do it yourselfer’s” can rent equipment to blow insulation into their attic space without the assistance of a professional. If the job is done right, they will save money, but if they make a mistake, they could make the problem much worse. It is not just insulation that causes an attic to get too hot, it’s also ventilation problems that cause excessive heat buildup in the space. That hot air in the attic needs to be removed and replaced with the much cooler outside air. Call an expert in the attic repair business to evaluate your attic problems. Professional work will help you maximize the results and possibly even save more in the years to come!

Ductless Mini Split Keller — September 14, 2018

Ductless Mini Split Keller

One of the most energy efficient air conditioning units is the ductless mini split system. These AC units can save any home or business well over 50% on their utility bill. Advances in technology are responsible for the high efficient performance in the air conditioner.

Ductless units are popular around the world. In the United States, mini split units are used to help cool or heat extra rooms in the homes. Man caves and media rooms are desired area to install these units. Some guys convert their hot Texas garage to a man cave with a ductless mini split to keep them comfortable.

In South America, ductless mini split units are the preferred air conditioning unit. Due to lack of space, mini split units have the capability to be installed almost anywhere in tight fitting dwellings.

A Filter is Just a Filter, Right? — September 12, 2018

A Filter is Just a Filter, Right?

Unfortunately, all filters are not created equally. Improper sized filters or even dirty filters are the number one reason for a furnace or air conditioner failure. We are here to take the mystery out of filter shopping and make sure your furnace runs as long and efficiently as possible.

1. Does Size Matter?
The size difference is pretty obvious, as some are rectangle, square, thick, thin, etc. The most important thing to remember is the thinner filters actually need to be changed or at least checked monthly. The 1″ filter panels usually don’t seal as well, resulting in air bypassing it, causing a shorter lifespan of your furnace. The thicker pleated filters (4″-5″ thick) only need to be changed twice a year. Also, the filter will do its job best when it is properly sized for your unit.

2. What is MERV Rating?
MERV stands for Minimum Efficiency Reporting Value and so you would think the higher the MERV rating the better, right? Not according to Mike, Mike’s Heating and Cooling generally recommends the highest rating of MERV 8. If you get much higher, the furnace has to work harder to draw air through the filter, which will hinder its efficiency and shorten the life of your furnace.

3. Pleated vs Panel

Economy panel filters are sold 4-5 in a pack and are inexpensive. These filters simply do not filter much and you will be replacing them about once a month.
Pleated filters, can last six months to a year, and are 10% to 60% more efficient.
