When Is It Time to Replace Your Commercial HVAC System?

Wednesday, February 25th, 2015

Commercial HVAC systems are similar to home heating systems in many ways. They include a lot of the same parts, they serve the same purpose, and they’re just as annoying to deal with when they break. The only real differences between them are that commercial HVAC systems are quite a bit larger, and they have more of an impact when they break down. Even with the best possible maintenance, however, it will eventually become necessary to replace your system with a new commercial HVAC installation. Let’s examine some of the signs that it’s time to replace your commercial HVAC system.

Escalation in Repairs

Though there will always be the odd repair need that crops up every once in a while, when a commercial heating system gets old enough the frequency of repairs will increase. This is because the various parts of the system will start to wear down from prolonged use. Each part wears out at a slightly different rate, which eventually results in several parts breaking in rapid succession. You can keep replacing these broken parts, but eventually you will have simply replaced the entire system one part at a time. As this is much more expensive than simply installing a new system, it’s usually a good idea to replace your old commercial unit when it starts breaking down more often.

Increase in Operating Cost

The same wear and tear that eventually causes cascading part breakage also contributes to decreasing the system’s efficiency. As the parts wear down, they slowly lose the ability to provide the same output that they did when they were new. This leads to the system working longer and longer to achieve the same results, which results in higher operating costs. Again, you could try to keep replacing parts until the efficiency improves, but it will never get back to the level it was at when the system was younger.

If you think that your commercial HVAC system is reaching the end of its life, call Command A/C. We provide commercial HVAC installation service throughout the Fullerton, CA area.

How an Electronic Air Purifier Cleans Your Air

Monday, February 16th, 2015

The filter in your HVAC (heating, ventilation, and air conditioning) system helps to eliminate some of the particles in the air that may aggravate allergies and irritate the sinuses. Most home HVAC filters can eliminate some of the most common contaminants such as pollen, dust mites, and various fibers. These filters trap particles to improve the health of those in your home and to help protect the heating and air conditioning system as well.

However, sometimes air filters aren’t enough to remove smaller particles from the air. As it turns out, air filters were designed to eliminate large particles that could clog the furnace or air conditioning system and cause it to struggle. If debris were to become lodged in the indoor blower fan, then the motor could stall and require replacement. Since filters were designed for this basic purpose rather than for air filtration, some of the standard filters don’t actually eliminate many of the worst contaminants from the air.

You could purchase a filter with a higher efficiency rating by choosing a filter with a higher rating on the MERV scale (minimum efficiency reporting value). Your home heating and AC system likely has a filter with a MERV of less than 6 even though the scale goes up to 16. However, if the MERV rating of a home filter is too high, the size of the filter may block airflow to the unit, hindering performance and perhaps leading to repairs. It may be a better idea instead to install an additional filtration system.

Electronic air purifiers work with your home HVAC system to eliminate more of the particles that pass through your ducts or throughout your home. Electronic air filters give the particles in your air a charge so that they become attracted to a surface with an opposite charge.

There are two types of electronic air filters: ion generators and electrostatic precipitators. An electrostatic precipitator contains an ionization chamber and two large metal plates. After particles are given a charge, they become attracted to these plates, which need to be cleaned about every few months. With an ion generator, these ions are sent throughout the room, charging particles in the air so they cling to surfaces in the home like the drapes or furniture, so that people in your home are less likely to inhale them.

Calling Command A/C gives you the choice between several different types of air purifiers in Newport Beach, CA, so that we can help you to select the unit that’s best for your family’s health and comfort. Contact our team of indoor air quality experts today for quality air purifier service.

Lupercalia: The Origin of St. Valentine’s Day

Saturday, February 14th, 2015

Many people may think of Valentine’s Day as a holiday essentially created by card and gift companies, but the truth is that the holiday has long-standing roots going back to the Roman Empire. The name “Lupercalia” has its origins in the word “lupus”, which means wolf, and the reason for this is that according to Roman pagan religion, the she-wolf Lupa nursed the two orphaned infants Romulus and Remus, the founders of Rome.


The Festival

The Festival of Lupercalia spanned two days each February, from February 13th to 15th. The festival was about fertility and was led by Luperci priests, known as “brothers of the wolf”. The festival was serious with intention (fertility) but was executed as quite a romp for both the priests and citizens of Rome. The process was this: two male goats and a dog were sacrificed at the beginning of the festival by the priests; two young Luperci were then anointed with the blood from the animals, and the hides of the animals were cut into straps. As food and drink flowed, the male priests would run around the city wearing nothing but thongs made from the animal skins, and they also carried a strap from one of the sacrificed animals. The strap was used to strike the palms of Roman women waiting for the priests in the city, as it was believed that being hit with the strap could help with infertility issues and a safe, healthy labor for women who were pregnant.


The Transition to St. Valentine’s Day

The Christian influence of the holiday came around the 5th century. The Roman Empire was still strong, but Christianity was rapidly taking hold throughout the world. It is believed that to try and remove the paganism from the holiday, the deaths of two men, supposedly both named Valentine, were added into the mix. During the 3rd and 4th centuries, a law created by Claudius II forbade young men eligible for military service to marry, because Rome wanted a strong army. The two men named Valentine were priests, and married young couples in secret. Both were found out and executed on February 14th, although in separate years. The Church made Valentine a saint (they chose one), and Lupercalia became St. Valentine’s Day.


Here’s wishing you and your loved one a Happy Valentine’s Day!

Reasons to Install a Heat Pump for Home Heating

Thursday, February 5th, 2015

Heat pumps are a fairly new, and very effective, method for home heating. Though they are still not well known among many homeowners, they are gaining more and more popularity across the country due to the unique advantages they offer. If you have never heard of heat pumps, read on to find out why they’re such a great choice for home heating.

What is a Heat Pump?

A heat pump is a heating system that does not use combustion of any kind. That is, it doesn’t burn fuel to create the heat that it uses. Instead, it takes preexisting heat from the surrounding environment and transfers it into the home. It is actually very similar to an air conditioner, the difference being that air conditioners transfer heat out of your home while heat pumps transfer heat into it.

A heat pump has two main parts, an indoor unit and an outdoor unit. The two units are installed inside and outside the house, respectively, and connected by refrigerant and power lines. When the heat is turned on, the outdoor unit evaporates refrigerant in a coil to draw thermal energy out of the air. The refrigerant gas then travels down the refrigerant line with the thermal energy, and into the indoor unit. The indoor unit condenses the refrigerant gas back into a liquid, releasing the thermal energy into the home.

Benefits of Installing a Heat Pump

The number one reason that people install heat pumps in their homes is because they are energy efficient. By using preexisting heat instead of burning fuel, a heat pump has to expend far less energy to accomplish the same amount of heat output. A heat pump will quickly pay for itself through saving money on your heating bills.

Heat pumps are also safer than combustion systems, which produce toxic combustion gases by burning fuel. A heat pump only uses electricity to operate, so there is no need to worry about things like carbon monoxide poisoning.
