HEATING, VENTILATION AND AIR CONDITIONING.


Emil Neagu Co.'s goal is to serve you, our customer, as professionally and efficiently, as possible. We know and understand your homes and your heating and cooling systems.

- If your system is inefficient, we can troubleshoot and give you an estimate. Sometimes, simple adjustments to duct registers are all that is needed.

- If your system is in need of repair, we will diagnose your system, explain the problem we have found, and answer your questions and concerns.

- If you need a new system, we will evaluate your home and make recommendations for a new or replacement system.

 

- Installing digital and wifi thermostats.


WHOLE HOUSE COOLING SYSTEMS.

- Unlike air conditioning units that guzzle electricity to circulate chemically cooled air, our revolutionary whole-house ventilation systems use positive pressure to draw cool, fresh outside air into your home, while pushing stale hot air out at 15-20 times per hour. This results in a more comfortable living environment, improved air quality, and a drop in AC usage by 50-90%. In some instances, AC is eliminated altogether! In fact, today's whole house exhaust fans pay for themselves on average within 1.5 years, making them the most cost-effective "green energy appliance" on the market.

PLUMBING.

- Repiping: troubleshoot new installation and repairs, Kitchens, bathrooms, water heaters, instant hot water recirculation.

Water treatment.

 

Install loop or replace water softeners. Install or replace reverses osmosis for water filtration, we also sell and install Ultima products from a local manufacturer

 

We call water "hard" if it contains a lot of calcium, magnesium or other minerals. Groundwater acquires these metals by dissolving them from surrounding soil and rock. Industry measures water hardness in terms of grains per gallon (GPG) or milligrams per liter (mg/L). A grain is defined as 64.8 milligrams of calcium carbonate. If your water tests at 1 GPG (17.1 mg/L) or less, then you have soft water. Water around 1-3.5 GPG (17.1-60 mg/L) occupies a gray zone between soft and slightly hard water and 3.5-7 GPG (60-120 mg/L) is moderately hard. Hard water is around 7-10.5 GPG (120 - 180 mg/L), and very hard water is above that.

How do all those numbers affect you? Hard water causes two problems:

  • Dissolved calcium and magnesium precipitate out of the hard water as scale, which builds up on the insides of pipes, water heaters, tea kettles, coffee makers and industrial machinery. Scale reduces flow through pipes and is a poor conductor of heat. Eventually, pipes can become completely clogged.

  • Hard water reduces soap's ability to lather, whether in the shower, sink, dishwasher or washing machine, and reacts with soap to form a sticky scum.

You can combat hard water in various ways, including filtering it by distillation or reverse osmosis, adding a packaged chemical softener such as powdered borax or washing soda (sodium carbonate), or running it through a water softener.

Filtration in sink taps and refrigerator water dispensers improves water's taste, but its steep price tag makes it impractical as a household solution. Packaged chemicals soften water in small batches, such as washing machine loads, but render the water undrinkable, take a toll on clothes, and, in some cases, contain phosphates that harm the environment.

Descaling offers an alternative to water softening. Whereas a water softener removes the problem (minerals in the water), a descale addresses the damage caused by the problem (scale buildup). You will sometimes see ads for "salt-free water softeners," which are actually descaled rs, or for magnetic water softeners, which remain unproven and don't change the chemical composition of water, so buyer beware.

With all this in mind, it's clear why water softeners are so popular: They remain the least costly and most effective way to rid your water of troublesome minerals.

Can save up to 16,000 gallons of water per year, per household
In Arizona, the average household consumes 126,632 gallons of water per year at an annual cost of $236.49. With new housing starts estimated to reach 54,903 per year by 2000, annual water consumption by new houses alone will total nearly 7 billion gallons at a cost of approximately $13 million per year. Were all new houses built in Arizona to include a Grundfos hot water recirculation system (with an average 200 foot supply line), water saved would total 16,534 gallons per year per household. The corresponding annual water bill would be reduced by approximately $32 and the energy bill by approximately $44. In total, hot water recirculation could save the state of Arizona nearly 950 million gallons of water per year and save new homeowners nearly $1.8 million in annual water charges.

The Basic Concept
Every homeowner gets frustrated waiting for hot water -- but how many stop to think what happens to the 2-3 gallons of water that run down the drain during the wait?

Those gallons of water are wasted, and in an average household that takes four showers per day, that can add up to thousands of gallons per year. Multiplied over a subdivision of 300 homes, a community can have millions of gallons of water go down the drain and into the wastewater system every single year.
In a region where water conservation issues are rising in importance with a rapidly expanding population and a record economic expansion that has consumers looking for comfort, Hot Water Recirculation pumps such as those manufactured by Grundfos Pumps Corporation are a good solution to this problem.
In typical plumbing, water is pumped from the water heater through the pipes to the tap. Once the tap is shut off, the water remaining in the pipes cools hence the familiar wait for hot water the next time the tap is opened.

HWR pumps offer a solution to the problem by attaching to the water heater through the hot water pipe. By constantly circulating hot water through the pipes from the heater to the furthest fixture, the water in the pipes is always hot, and no water is wasted during the wait. In an average new home, HWR systems typically cost less than $ 500,00 including parts and installation.
