What Are Dual Fuel Systems and How Do They Work?

Friday, May 30th, 2014

Heat pumps are one of the best systems available for home comfort on the market today. These systems can either heat or cool a home, and instead of burning fuel to do their job—like furnaces and boilers—they work through the system of heat exchange that moves heat from one place to another using only a modest amount of electricity. Heat pumps are fantastic ways to have year-round comfort in Arizona.

There is one disadvantage that heat pumps have, however, but through the use of a dual fuel system, they can overcome this. We’ll look into dual fuel AC systems in Tempe, AZ and what they can do for you. For a consultation to see if a heat pump is ideal for your home, either on its own or as a dual fuel system, call Goettl Good Guys Air Conditioning. We have many years of experience finding ways to cool and heat the Valley of the Sun.

How dual fuel hybrid systems maintain heat pump efficiency

Here is the main drawback of heat pumps: at extreme low temperatures, they will have trouble with maintaining their heating efficiency. Because a heat pump must remove heat from outside and bring it inside when in heating mode, the lower the outdoor temperature, the less heat is available for it to use. In most cool temperatures, this is not a problem—but when the thermometer drops below the economic balance point (which varies based on humidity), the heat pump will begin to experience troubles.

A dual fuel hybrid system combats this with a smaller backup heater that uses a different fuel source. Most backup heaters are natural gas furnaces, although propane furnaces are also common for homes that lack access to a natural gas pipeline. When the temperature reaches the economic balance point and the heat pump starts to lose efficiency, the backup heater automatically switches on and compensates for the loss of heat. As soon as the temperature rises back above the economic balance point, the backup heater shuts off.

Since heat pumps are known for their energy saving abilities in heating mode, a dual fuel system is an effective way to bump up a heat pump’s performance while only making a small extra sacrifice in costs. The backup system will only need to run occasionally, so it’s a less expensive option than having a full furnace or boiler rather than a heat pump.

Your home may not have the need for a hybrid system to assist the heat pump; to find out, call on the experts at Goettl Good Guys Air Conditioning.

Benefits of Professional Air Duct Cleaning

Friday, May 23rd, 2014

If you looked at the title of the post and thought, “Duct cleaning, huh? Haven’t thought about having my home’s ductwork cleaned,” then you definitely need to have your home’s ductwork cleaned.

Furthermore, as we emphasized in the title, you need professional duct cleaning. This isn’t a situation where you can pry the covers off of vents, push a vacuum hose down the duct, and hope for the best. The extent of the ventilation system and the heavy levels of different contaminations that can develop inside it (remember, air from everywhere in your house circulates through the ducts) require the work of trained cleaners.

But it’s easy to take care of duct cleaning in Mesa, AZ: call Goettl Good Guys Air Conditioning and talk to our indoor air quality specialists. We’ll handle your duct cleaning, and you’ll receive these important benefits that only professional work can provide:

Improved indoor air quality

Your ducts will eventually become a reservoir for airborne contaminants that cycle through the ventilation system and begin to accumulate. The debris can include dust, dust mites, dander, hair, pollen, sawdust from remodeling and construction, lint, and carpet fibers. You don’t want all that blown out in your home’s air every time the air conditioner or heater turns on. These pollutants are especially dangerous for people with asthma or allergies. Duct cleaning will take away a major health threat in your home.

More efficient HVAC system

The level of clogging and clotting along the walls of a ventilation system can be astonishing—and it’s more than enough to put friction on the airflow from your air conditioner/heater. Only a thin layer of dust is enough to affect the passage of air, and this puts pressure on the HVAC system. After a cleaning, however, you can expect lower utility bills as the HVAC system “breathes” easier. The system will also experience fewer repair needs due to overworking and consequently last longer.

A cleaner home

The contaminants the ductwork circulates through a home won’t stay in the air all the time. They will settle along your furniture, carpet, wood floors, corners, etc. A home with clogged ducts will become a dust magnet, where you can clean every day and have the dust come right back again. Clean ducts mean a sparkling home—or at least one you won’t have to work as hard to keep sparkling.

A good professional cleaning job only takes a few hours, and you should have it done every two years (sometimes more often, depending on your home).

Why Are Commercial Air Conditioning Systems Located on the Roof?

Friday, May 16th, 2014

The great workhorses of the commercial HVAC world are packaged rooftop units that serve to both air condition and heat a workspace. You’re probably familiar with the sight of these from any time you’ve been high up enough to see the tops of buildings. However, residential homes rarely have their heat pumps or air conditioners on the roof (although you see it occasionally, usually for evaporative coolers, a.k.a. swamp coolers), so why are commercial systems different? We’ll look at this further in this post.

If you operate a business with packaged rooftop air conditioning, then you must rely on professionals to handle maintenance and repair work. For quality commercial air conditioning in Paradise Valley, AZ, look to the many decades of experience here at Goettl Good Guys Air Conditioning. We’ve served the Valley of the Sun since 1939 and offer high-efficiency commercial AC installation, repairs, and maintenance.

Why is that AC up on the roof?

Air conditioners first moved up to the roofs of commercial buildings because conditions in downtown U.S. cities, with high-rises pressed close to each other, were too crowded to allow placement on the ground. Because the roof location offered other advantages, the air conditioners have remained up there even in less congested commercial districts.

Considering how large commercial air conditioning systems need to be in order to meet the cooling requirements of a business, the roof is one of the most economical and attractive places to install them. An AC on the roof not only consumes less valuable commercial space, it looks better. Although modern HVAC manufacturers strive to make their units systems as sleek as possible, air conditioners are still not “pretty” to look at, so keeping them restricted to a place removed from eye-level creates a less cluttered and inviting appearance for a business. Since these large ACs also generate a great deal of noise when they run, putting them on the roof keeps extra sound pollution out of the workplace.

Rooftop units are easier to service without causing disruption to a business. A rooftop AC for a home is a nuisance to access—even potentially dangerous—but for a business it is an ideal spot.

The HVAC systems for businesses are more prone to damage from outdoor elements, as well as possible targets for vandalism. The rooftop location keeps the sensitive components of the AC removed from damage due to vegetation, gravel, cars, and humans.

Keeping your business’ workplace cooled down during the heavy Arizona summers is important for the happiness of your employees, customers, and clients. We take pride in the work we provide for commercial air conditioning in Paradise Valley, AZ, and we will strive to deliver complete satisfaction that will make us your regular choice for AC service. Call us today.

If you encounter any troubles with your rooftop air conditioner, you can reach Goettl Good Guys Air Conditioning any time of the day or night for emergency service.

How an Old Air Conditioner Costs You Money

Friday, May 9th, 2014

If you have considered replacing an aging air conditioning system, but have held back because the AC still seems to keep the house at the same level of cooling it always has, then you might be throwing away money and not realize it. An air conditioner can still outwardly produce the same amount of cooling that it has for many years, but inwardly run inefficiently and elevate to raise your bills.

At what point is an AC overdue for a replacement? To help answer that question, let’s look at how an aging air conditioner in Mesa, AZ can cost you extra money.

For help from experienced air conditioning professionals in determining whether the time has come to replace your cooling system, depend on Goettl Good Guys Air Conditioning. We’ve helped keep one of the hottest cities in the country cool since 1939.

Why old air conditioners waste money

Air conditioners are electro-mechanical devices; like any mechanical device—from a car to a washing machine—it will start to wear down from stress over the years. Regular maintenance will slow down this aging process and expand the system’s lifespan, but eventually the decay on the components will reach a point where the air conditioner will begin to strain to perform its job, and no amount of repairs or maintenance will reverse it.

The component that is most susceptible to irreparable wear is the compressor, which is also the heart of the operation of an AC. The compressor runs similar to a piston engine, and can succumb to similar mechanical stress that will cause it to siphon off additional energy in order to run. If the compressor burns out, the system will not work, and because it is expensive to replace a compressor, this usually means the entire air conditioner must be replaced.

Air conditioners come with a manufacturer’s estimated lifespan; if your unit has exceeded it, than it is likely already costing you money because of stress on the compressor or declining electrical components. Check over the last two years of your utility bills to see if there was an increase in electrical costs during the summer. This will point to an aged air conditioner beginning to fail; arrange for an AC technician to look into the matter and see if it is time for a replacement.

Finally, if your air conditioner is old enough, it was probably always less efficient than the current models available. Recent advances in HVAC technology—such as improved refrigerant blends—have increased the ability of air conditioners to convert electricity into cooling; you can probably find a new unit with higher energy efficiency that costs around the same as you paid for your current system years ago.

Don’t let a faltering cooling system inflate your summer bills: call Goettl Good Guys Air Conditioning today and talk to us about installing a new air conditioner in Mesa, AZ.

Does Insulation Save You Money in the Summer?

Friday, May 2nd, 2014

Home insulation in Chandler AZ doesn’t have the same priority as it might in, say, Bangor ME. People associate insulation with staying warm in the winter, and indeed that’s one of its main functions. But the same principle that makes it work so well in cold weather also makes it work in hot weather. That means you should think very seriously about improving your insulation, perhaps even more than you might in a colder environment.

Does insulation save you money in the summer?

The principles of insulation involve three distinct concepts: conduction (the way heat moves through solid materials), convection (the way heat mores through liquids and gases) and radiation (the way heat warms the temperature of anything in its path. Insulation works to slow that process in the first two instances and often the third as well. It’s composed of material that slows the transfer of heat, whether it be fiberglass, rigid foam or even sheep’s wool. It’s also why you want to have lots of insulation in your attic, since warm air rises and moves towards the highest spot in the house.

However, that process isn’t just one way. The same concepts that help the insulation keep warm air inside your home also keeps outside hot air from getting into your home. In other words, the cool air generated by your air conditioning system will stay in your home longer and your air conditioner won’t need to spend as much energy to keep you home cool. That translates to lower monthly cooling bills over the summer, as well as a reduced risk of breakdowns and lower stress on your air conditioner overall.

Knowing that insulation saves you money in the summer means that you may wish to consider adding more before the Arizona heat rises beyond comfort. And for home insulation in Chandler AZ, the experts at Goettl Good Guys Air Conditioning are ready to help.

We know a number of techniques to make your home more energy efficient, including the addition of more insulation. Give us call today to set up a consultation.
