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.

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.

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.

Ductless Heat Pump…Why you just might need one — September 7, 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.

Furnace Repair — September 6, 2018

Furnace Repair

Furnaces filter, heat and distribute air around your home. Furnaces are invaluable for providing heat for your home and family. Spare yourself the discomfort of a cold night or winter day due to a broken furnace. It is important that you call a professional to inspect your furnace if you suspect that it is in need of repair.

Hot air is a simple yet necessary convenience. It is easy to ignore a furnace. We simply expect the furnace to heat our home when we turn it on. Many people do not notice their furnace until it is already broken. Some signs that your appliance is malfunctioning and in need of repair include:

  • Strange noises coming from the furnace
  • Air that smells musky or dirty
  • The furnace takes too long to heat the air
  • The air does not heat at all

Turning Vanes: Necessary Component, or Efficiency Reduction Device? — September 5, 2018

Turning Vanes: Necessary Component, or Efficiency Reduction Device?

The installation of turning vanes in HVAC ductwork is perhaps one of the greatest sources of contention between mechanical contractors and HVAC engineers. Why? Because many mechanical contractors believe that turning vanes can cause the ductwork to become less efficient by increasing the pressure drop in the system, as well as adding time and expense to the overall installation.

This belief seems to be based in simple logic: when there is more surface area exposed to the airflow, the amount of friction will be increased, and the harder the fan must work to achieve the required airflows. In some cases when an HVAC system is having particular difficulty in supplying the required amounts of airflow to all zones, many mechanical contractors will recommend the removal of every other turning vane at each fitting in the system in order to “reduce the friction” in the duct.

This practice is a violation of turning vane spacing requirements, and has also been condemned by the Air Conditioning Contractors of America because it decreases the uniformity of the airflow and increases the pressure drop in the system). The question is, does reality match up with popular belief?

Air Conditioning Maintenance
Befоre you go blasting the coоl aіr from your A/С, make sure you’ve given your trusty аррlіаncе іt’s уearlу check-uр or an air conditioning maintenance. Аir cоndіtіоnеrs requіre rеgulаr maіntеnancе to wоrk at their peak. Іf you fоllоw thetiрs each уear, you’ll be staying соol and sаvіng cаsh—іn enеrgy bills and uneхpeсted rерaіr costs.

1. Сhangе the fіltеr.
Centrаl аіr systеms should have their fіltеrs chаnged at least every few mоnths. But if you’ve let the chоre slіde to the back of your mind, nоw’s as gооd a time as any to reрlacе the fіlter.

2. Clean the vents.
Аgаіn, a rеgular dustіng several tіmes a yеаr is a must. Вut if you’ve been slаckіng, do it now. Yоu could also considеr having a professiоnal give your аіr duсts and vents a thоrоugh clеаnіng.
