Your Options for New Heating Installation during the fall

October 9th, 2014 by Stephen Andrews

There is a myriad of heating options available for your home. From heat pumps, to solar, to ductless heating, there is bound to be an option that perfectly fits your heating needs. Let’s take a look at some of your best options for heating installation this fall.

Heat Pumps

Forced air heat pumps are very similar to traditional heating systems, with a few unique qualities that give them an edge. A heat pump is comprised of both an indoor unit and an outdoor unit. The outdoor unit uses coils to draw in thermal energy from the surrounding air. This energy is added to the air in the indoor unit, which is warmed further and then circulated throughout the house. It is this absorption of thermal energy that makes the heat pump so efficient. Heat pumps don’t operate quite as well in extremely cold environments. If you aren’t constantly buried in snow, however, a heat pump could be a great option for you.

Solar Heating

Solar heating is rarely used to completely replace a more traditional heating system. However, it can be a great way to lower your heating bills by supplementing the system you already have. Solar heating begins by installing a panel on the roof. This panel collects thermal energy from sunlight and directs it down to a solar storage unit. This unit then adds the extra thermal energy to the air being circulated by your other heating system. Solar heating requires a bit more of an upfront investment, but it is about the most energy efficient system available. Since it doesn’t absorb thermal energy from the air, it operates better in freezing environments than heat pumps do.

Ductless Heating

Ductless heating systems use an individual indoor unit for each room you want heated. The outdoor part of the unit works much the same way as a heat pump, absorbing and directing thermal energy to the indoor unit to be circulated. The advantage of the ductless system is that you only need to spend energy heating the room you are currently occupying. This can save you a lot of money on heating bills.

If you are thinking about installing a new heating system this fall, call Cool Air Mechanical. Our experts in heating installation cover the entire Kennesaw, GA area.

 

3 Reasons to Consider Heat Pump Installation for the fall

October 8th, 2014 by Stephen Andrews

Heat pumps are effective and efficient heating systems. What makes them a better choice than all the other heating options out there, though? If you’re considering installing a new heating system this fall, read on to discover the 3 reasons why a heat pump may be right for you.

Energy Efficiency

A heat pump consists of an indoor unit and an outdoor unit. When the heat pump is in heating mode, the outdoor unit draws thermal energy from the air around it. This energy is transferred to the refrigerant line, which runs from the outdoor unit to the indoor unit. The indoor unit then uses this thermal energy to heat and distribute air throughout the house. By moving thermal energy in this way, the heat pump expends less energy on heating than other systems. It does not require the use of a gas-burning furnace to heat the air.

Versatility

A heat pump is actually capable of both heating and cooling. It does this through the use of a part called a “reversing valve.” This valve reverses the flow of refrigerant between the indoor and outdoor unit, depending on which mode the heat pump is in. By combining both heating and cooling into one unit, the heat pump saves you the time and space of installing a separate air conditioning system for the summer months.

Savings

The combination of both energy efficiency and versatility results in sizeable savings on your heating bill, compared to other heating systems. Over time, the unit will eventually pay for itself with these savings. The installation procedure and investment is comparable to more traditional systems, so there isn’t a drastic increase in initial cost. These savings tend to be the number 1 reason that people switch to heat pumps from other systems.

If you want to gain all of these advantages by installing a new heat pump, call Cool Air Mechanical today. Our HVAC technicians are all professionals when it comes to heat pump installation in the Atlanta area.

 

Watch for These Signs That Your Heat Pump Need Repairs

October 1st, 2014 by siteadmin

Your heat pump kept you cool all summer long, and now it’s almost time for the heating season. Since your heat pump runs throughout the year, there is always a chance that parts of your heat pump may begin to decline. Heat pumps get a lot of usage, which means the parts go through a lot of strain over the course of a year. And this means that components can become worn to the point that they need replacement, which is why it’s important to pay attention to some of the following signs that you need to call for heating repair.

  • Reduced Heating/Cooling: While reduced heating and cooling is not usually ideal, some homeowners find it bearable. At the end of the summer, you may believe that your family can put up with some reduced cooling and you can wait for repairs. However, limited air conditioning can mean that you have a refrigerant leak that must be sealed, a faulty motor, or even compressor trouble. These problems must be addressed before the heating season.
  • Higher Bills: Did you notice your bills increasing throughout the cooling season? This may be a sign that you need to schedule heating repair. A heat pump that cools inefficiently will not run properly for heating either, and it usually signals a major repair need.
  • Loud Noises: Unusual sounds from your heat pump should always be a cause for alarm. A banging sound could indicate anything from a loose fan blade to a faulty compressor, while a hissing noise could indicate a leak in the refrigerant line.

Because your heat pump runs all year long, it’s vital that you schedule heat pump maintenance two times per year. Maintenance is a valuable service in which a technician checks every portion of your system for potential problems. Various parts of your unit are also cleaned or adjusted, which not only wards off repairs but may also decrease your energy bills. The folks at Cool Air Mechanical can check your unit for repair needs, locate the problem, and decide on the right way to correct the problem.

Signs That It’s Time for New Commercial HVAC Installation in Dunwoody, GA

September 25th, 2014 by siteadmin

Your commercial HVAC system is important to your business, keeping clients, customers, tenants, and/or employees as comfortable as possible. These large systems are built to last a long time, but any unit will fail eventually and require new commercial HVAC installation. So how do you decide whether you need a new system or if you only need repairs?

Often, problems with your commercial unit simply indicate the need for repair. With commercial units, every component of both your heating and air conditioning system is combined in a single outdoor cabinet. As this cabinet is usually placed on the rooftop and is often fairly exposed to the outdoor elements, repairs are to be expected from time to time. Usually, a technician is the best person to decide whether it’s best to repair or replace your system. But the following signs may indicate a need for replacement.

  • Frequent Repairs: Because your commercial heating and air conditioning unit is so large and complex, you should expect to call for repairs from time to time. But if you have had to call for repairs many times in recent years, it likely means that parts of your AC are failing beyond repair. Simply put, replacing your entire unit will be less expensive than replacing failing parts one by one.
  • High Energy Bills: High energy bills may indicate a number of problems with your HVAC unit, many of which can be fixed with repairs. But if you’ve scheduled maintenance and made any necessary repairs, high bills could actually indicate that many components of your HVAC unit are too worn to efficiently cool or heat your business. This is particularly true of units that are over ten years of age.
  • Old Age: Older systems are more likely to break down right in the middle of a busy work day. Check the expected lifespan of your unit and be sure to replace it before this time runs out, particularly if you’ve noticed problems with your unit in recent years.

If you need help deciding whether repairs will keep your unit running for a few more good years or if it’s time for commercial HVAC installation in Dunwoody, call the experts at Cool Air Mechanical today!

When Is an Electric Water Heater a Good Option for My Home?

September 24th, 2014 by siteadmin

When you need a new water heater in Marietta, it may be difficult to decide on your own which type of unit is right for your home. Today, there are many new types of units available on the market. Storage tank water heaters remain the most popular type due to the lower cost, but tankless water heaters are rising in popularity. In general, however, if you’ve never run into problems with your traditional storage tank water heater, you may decide to replace it with a similar system. But when you need a storage tank water heater for a new home, or if you’re looking at different options, there are two general types of unit, electric and gas-powered, which may lead you to wonder which type is right for you.

Electric water heaters work using the same heat rising principle as gas-powered heaters. A pipe that leads to the bottom of the tank lets cold water in. Here, a burner heats the water from underneath the unit in a gas-powered water heater. With an electric unit, a heating element inside the tank heats the water instead. Hot water naturally rises above the denser cold water and flows into your home through a pipe positioned at the top of the tank.

Both types of units are about equally effective at providing hot water. But for the most part, people choose electric water heaters when they don’t have access to natural gas service. While gas heaters may be more costly than electric, the cost of operation tends to be much higher with electric water heater units because the cost of electricity is higher than the cost of gas in most areas. However, an electric water heater may best for those who need a smaller unit to heat water for a smaller apartment. In fact, you can even upgrade your system with an insulated water heater blanket to prevent heat loss and lower your bills.

The decision ultimately has to do with the size of your home and your family, your energy concerns, particular needs for installation and monthly cost, and what type of system you are replacing. A professional technician will discuss the cost of installation as well as which types of units may be most efficient in your home. Cost will vary depending on what size tank you need and any upgrades you choose, so you should always check with your technician first.

Are Air Conditioners Easier to Repair Than Heat Pumps?

September 17th, 2014 by Stephen Andrews

Air conditioners and heat pumps are often placed together in the same category. The reason for this is that an air conditioner is a type of heat pump, and a heat pump can do the same job as an air conditioner. Essentially, a heat pump is an air conditioner that can reverse the direction it moves heat and so work at both cooling and heating a home. The two systems work through an identical process of heat exchange using the cycling of refrigerant.

There are some differences mechanically between the two—heat pumps have more components to allow them to operate in different modes—but they are much more similar than they are dissimilar. Repairs for heat pumps and air conditioners are also similar.

Which one is tougher to repair? It depends on the kind of repair, although generally the repair types are the same. However, both are difficult if not impossible to repair without the proper training and tools. Unless you are a licensed HVAC specialist, you should never attempt to open up the cabinets of an AC or heat pump and try to manage repairs on your own. Always contact professionals: you can reach Cool Air Mechanical for heat pump and air conditioning repair in Kennesaw, GA any time of the day or night.

What Are the Differences Between Heat Pump and AC Repairs?

The major way that the two systems are different from each other is the presence of a component called the reversing valve. In a heat pump, the reversing valve sits on the refrigerant line where it exits from the compressor. Depending on whether the valve is “excited” (electrically charged) or not, it will direct the refrigerant either toward the indoor coil or the outdoor coil, thus determining whether the heat pump is in heating or cooling mode. Because an air conditioner is always in cooling mode, it does not have a reversing valve. If the valve in a heat pump malfunctions, it will need replacement.

Heat pumps also have a dual set of condensate pans that drain excess moisture, one each for the inside and the outside cabinets. Air conditioners only have one condensate drain, located on the indoors. This makes heat pumps a bit more complicated to maintain and to locate repair issues, but not significantly so.

Any skilled technician who can repair a heat pump can provide repairs for an air conditioner, so make sure that you turn to the professionals whatever system you have and whatever repairs you need. Contact Cool Air Mechanical when you need heat pump or air conditioning service in Kennesaw, GA.

3 Most Common Commercial HVAC Repairs

September 11th, 2014 by siteadmin

If you own or manage a commercial property, your clients, customers, and employees need a calm and comfortable place to conduct business. Your HVAC system helps do a lot of this work for you, so it’s important to call for repairs at the first sign of trouble. However, many people are too busy to notice right away when their commercial unit has run into problems. Instead, you may rely on your employees, customers, or even your bills, to let you know about the following problems that lead to commercial HVAC repair.

  • Insufficient heating or cooling: One of the most common reasons business owners call for HVAC repairs is if the people on the property notice limited heating or cooling in one or several areas of the building. This may be due to any number of issues within the HVAC system, including a frozen coil or thermostat troubles. When someone complains, it’s a sure sign that immediate repairs are needed to keep your business running smoothly.
  • Noises: Loud noises will also disrupt the normal flow of business, and these are a pretty good indicator that something is wrong. A damaged fan blade, for example, which may make a loud clanking sound, disrupts airflow and may eventually keep you from feeling any cool or warm air whatsoever. However, commercial units are often located on the roof, so you may not always hear indicators of problems. In this case, you may have to rely on other warning signs.
  • High Bills: One of these indicators is a particularly high energy bill. The bills for your commercial property are already fairly large, but a broken or dirty part can cause these to be even higher. Broken parts cause your air conditioning and heating system to run for longer periods of time, meaning it may consume a lot of energy even for a simple repair need.

When you need commercial HVAC repair in Duluth, no ordinary residential air conditioning service company will do. You need professional technicians with experience repairing large packaged units. Call the experts at Cool Air Mechanical at the first sign of trouble for all of your commercial HVAC repair needs.

Can I Do Water Heater Repairs on My Own?

September 10th, 2014 by siteadmin

Do-it-yourself projects are a great way to save a little money and learn a new life skill—in some situations. But when it comes to your home’s water heater, professional technicians simply have more experience dealing with water heater repair, and can better ensure everything gets back to normal as soon as possible. This is a large piece of equipment, so a poor repair job may lead to costly replacement. If you want to make a sweater, test out a chili recipe, or try your hand at flower arrangements, by all means, do it yourself. But here are the reasons you should not attempt to make any water heater repairs on your own.

The Problem May Not Be What You Think

Sometimes, a problem with your water heater may seem to be another problem entirely. A quick internet search can bring up dozens of sources for any repair need and you may choose the one that seems most logical. Noises from your tank? Simply flush out the tank to drain sediment rattling inside of the tank, right? Not necessarily. Noises from your tank may require a technician to check the pressure valve, or look for other problems within the pipes.

If you turn on your hot water and notice that the water is rust-colored, an internet search may inform you that you should replace the rusty anode rod. Or an ill-informed guide may tell you to drain your unit. However, rust colored water may indicate a more serious problem. You’ll want a professional to rule out storage tank corrosion before making any quick repairs.

Professionals Are Experienced and Are Equipped with the Right Tools for the Job

A professional simply has the right tools and know-how to take care of a water heater repair quickly and professionally. Without a trained eye to look at the problem, you simply cannot be certain you are taking the right course of action. For water heater repair in Roswell, trust one of the experts at Cool Air Mechanical. We’re open 24/7 for emergency repairs and have the right equipment to get your water heater running smoothly today! Call us today to schedule an appointment.

The Fashion of Wearing White and Labor Day

September 1st, 2014 by Stephen Andrews

You may have heard about the fashion faux pas of wearing white after Labor Day. In the present, this tradition is usually treated as old fashioned and a joke. Few people will criticize you for wearing white articles of clothing after the first Monday in September, or even take notice of it except to wonder why it was ever a major concern at all.

Where did this tradition of white clothing going out of fashion after Labor Day come from, and why did it fade away like colorful fabric washed in a hot load in the washing machine?

In general, white makes sense for the heat of summer. Light-colored clothing reflects away the radiant heat of the sun, instead of absorbing it the way dark colors do, so for thousands of years of human history people have preferred to wear white clothing during the hotter months.

However, the idea of white as strictly fashionable during the summer season only emerged in the nineteenth and early twentieth centuries—the time when the very concept of “fashion” began to spread across the Western Hemisphere.

It was only the highest level of post-Civil War society in the U.S. that strict and often bizarre rules for fashion controlled whether someone was in with the “in” crowd. Compared to our ideas of what’s fashionable today, the Czars of Style in the 1880s were true despots. Things as trivial as sleeve length could determine whether a woman in high society—no matter her level of wealth—was fashionable or a pariah.

Wearing white during the only summer, when it was common for weddings and outdoor parties, was only of these restrictive society rules. When the U.S. government made Labor Day a federal holiday in 1894, the Fashion Czars gained a definite cut-off point for when wearing white was no longer “acceptable” in the upper echelons of wealthy society.

For many decades, this rule only applied to a small number of millionaire socialites in a few big cities, but in the 1950s it reached general fashion magazines that were read around the country and started to affect more people.

But time eventually broke apart this odd rule, and during the 1970s fashion became more individual. Some fashion legends, like Coco Chanel, also purposely rejected the restriction and wore white throughout the year. Today, the “no white after Labor Day rule” is little more than an amusing gag to tease friends, and almost nobody takes it seriously.

Whatever you choose to wear after Labor Day (and if it’s white, we won’t tease!), everyone here at Cool Air Mechanical hopes you have a happy end of the summer and great plans for the fall!

3 Common Signs That You Need Commercial HVAC Repair

August 28th, 2014 by Stephen Andrews

Problems with your commercial HVAC system can have a direct impact on your business; this is why it’s so important to attend to repairs right away. You don’t have to be an HVAC expert to spot the signs of developing problems, but it does help to know what to look for. Our Cool Air Mechanical technicians have put together a short list of common signs that can indicate the need for repair to your commercial HVAC system in Marietta.

3 Signs of Possible Problems

Following are 3 signs your commercial AC may be experiencing problems:

  • AC is blowing warm air – there are several problems that can cause your air conditioner to blow warm air, but the bottom line is that no matter what the reason, it needs to be fixed quickly. This is why it’s important to hire a technician who has experience with commercial HVAC systems.
  • Decrease in airflow – it won’t matter how cool your air is if you aren’t getting enough of it. A decrease in airflow can be the result of blockages, faulty ductwork or fan problems. Problems with airflow can put stress on your AC system, so the sooner it can be repaired, the better for you and your AC.
  • Excessive humidity – are you feeling extra moisture in your business space? Excess humidity can cause problems beyond discomfort, including damage from moisture and mold and mildew growth. No business owner wants to see products or merchandise ruined by excess humidity, so it’s best to call a professional as soon as possible.

Why It’s Important to Hire a Commercial Specialist

Commercial HVAC systems are large and complicated, especially when compared to residential systems. This is why it’s important to hire professionals with commercial HVAC repair experience.
