How Geothermal Cooling Systems Work

Friday, May 30th, 2014

Most people understand the basics of geothermal power: the planet Earth generates heat from its core, which then radiates outward toward the surface. Only about 10 feet below the ground, the Earth’s temperature starts to rise. Anyone who has gone into an underground cavern for any distance during cold weather will attest to the increase in temperature down below the surface. Systems that harness this heat are accessing a natural, clean, and renewable source of energy.

But how does this relate to cooling down a home? A geothermal heat pump can both warm up and cool down a home, and we’ll explain how this works.

To find out the necessary information to see if geothermal cooling in Andover, MN is appropriate for your household, call up the geothermal experts at Air Mechanical, Inc. today. Since 1985, we’ve cooled and heated the 7-county Metro Area.

The operation of a ground-source heat pump in cooling mode

A geothermal heat pump works much the same way that a standard air-source heat pump does: to cool your home, it removes heat from your indoor air and deposits it in the air outside. The process reverses for heating. The difference is that a ground-source heat pump (i.e. a geothermal heat pump) uses the ground for half of the exchange: it removes heat from the earth and moves it indoors for heating, and when you switch the system over to cooling, it removes the heat from indoors and puts it in the ground.

Because the temperature in the ground remains at a steady level that is hardly affected by the fluctuations of surface weather, the geothermal heat pump always has a heat supply for the exchange: at around 55°F, it works ideally to remove and deposit heat. The ground loops that carry out the exchange run water through them to move the heat from one place to the other, and without causing any damage to the soil. Ground-source heat pumps are both reliable and clean, with few emissions that might endanger the environment.

But will a geothermal heat pump work for my home?

That’s a good question. It isn’t one we can answer here: every house and property is different. Limitations on space and differences in the soil can make a geothermal system impractical in some locations. However, our specialists at Air Mechanical, Inc. will find the best way to either apply a geothermal configuration for what you have available, or suggest an alternative for heating and cooling that will bring you comfort and energy savings.

We are strong advocates of geothermal energy for homes, and we want you to take them into serious consideration.

At Air Mechanical we do our best to see that you have excellent geothermal cooling in Andover, MN if it is the finest option for your home.

How Sump Pumps Work in Oak Grove

Friday, May 23rd, 2014

The combination of heavy rainfall and high water tables in many places in Oak Grove means the lower parts of homes can face trouble from flooding and excess moisture. Water entering basements and crawlspaces causes damage to building material and objects in storage, contributes to an uncomfortable rise in humidity, encourages the growth of unhealthy molds and mildew, and attracts pests like cockroaches and rodents. This is a problem you must solve.

The best solution is to install a sump pump to remove the excess water. A sump pump takes the worry off your mind and automatically keeps your basement dry and safe. For more detailed information about sump pumps in Oak Grove, MN, specifically to find out what type and size of sump pump will protect your basement and/or crawlspace, contact Air Mechanical, Inc. Your comfort is our concern, and has been since 1985.

The operation of sump pumps

At their basic, sump pumps are electrically-powered impeller pumps that remove water from an excavated area called a sump and transport it into the wastewater system (or sometimes a well). The sump is created in a location where water flows naturally into it and begins to collect so that the water level is high enough for the pump to be able to remove it.

There are two standard sump pump models.

  • Pedestal sump pumps, as their name implies, perch on a pedestal over the sump. The impeller is located at the bottom of the pump, and from it a pipe extends down into the sump. A float in the sump activates the impeller when the water level rises too high, and the water is pumped out until the water in the sump returns to its original level. Pedestal pumps need more power to run than the other model, but they are easy to service and suffer from less water damage because they are not in the sump.
  • Submersible sump pumps sit down within the water of the sump and draw water directly into their intakes. Whenever water is high enough to enter the intakes, the impeller motor turns on. Although sealed to prevent water damage, submersible pumps will wear down faster and need more repairs than pedestal pumps. However, they are more visually appealing than pedestal sump pumps (because they are mostly hidden) and use less energy because they do not need as much suction power.

What kind of pump should I get?

This is a question best left to a professional installer to answer. He or she can determine based on the layout of your basement and the amount of water it collects the type and size of pump to do the job. The installer will set the unit up for you, and you can rely on him or her for repairs and necessary regular maintenance.

Our staff at Air Mechanical, Inc. has many years of experience with sump pumps in Oak Grove, MN. Trust to us to protect your home from flooding and excess moisture.

How a Whole House Dehumidifier Can Save You Money This Summer

Friday, May 16th, 2014

The greatest enemy of comfort during the summer is heat. But humidity is a close second. A dry day can make high temperatures much more bearable. But when the moisture level of the air rises, it blocks your body from effectively releasing heat through sweating, making you feel hotter than the actual temperature.

One way to defeat humidity during the summer season is through the installation of a whole-house dehumidifier. Dehumidifiers do more than make a home feel pleasant: they will also save a homeowner money in a number of different ways.

Installing a whole-house dehumidifier requires an indoor air quality specialist who can determine how large a dehumidifier you need and then properly fit it into your HVAC system.

For services to select and install a whole-house dehumidifier in Ham Lake, MN, look to the experienced indoor air quality team at Air Mechanical, Inc.

How a dehumidifier saves you money

A dehumidifier will start to immediately reduce your utility bills once it comes on. Because your home will feel cooler with lower levels of moisture in the air, you will not need to run the air conditioner as often. Along with making your electrical bills smaller, the reduction in stress on your air conditioner also means fewer repair needs and a system with a much longer lifespan. What better way to save money in the long term than to have a few extra years of air conditioning service before you need to have it replaced?

Don’t worry about the extra electrical cost to run the dehumidifier. Dehumidifiers use only a fraction of the power that an air conditioning compressor does. (A central AC averages 220 volts, while a dehumidifier averages 100 volts.) If you can reduce your air conditioning use by only an hour a day because of the action of a dehumidifier, you will save around $20 a day… and you will probably manage to reduce your use much farther.

Air conditioning systems do reduce humidity through their action of absorbing moisture onto the evaporator coils. However, air conditioners are not specifically designed to control humidity and have little effect on any humidity level higher than 50%. If humidity is a serious problem for your home, it is a wise idea to invest in a whole-house dehumidifier to augment the air conditioner.

The other benefits of a dehumidifier—less moisture damage to furnishings, mold and mildew growth reduction, and improved health—will save you money in less direct but nonetheless significant ways.

If humidity is making your summer unpleasant, or if you’ve noticed moisture damage in your house, you should consider installing a whole-house dehumidifier in Ham Lake, MN. For consultation and installation services that will make sure you end up with the ideal dehumidifier, call Air Mechanical, Inc. today.

3 Ways to Make Your New Air Conditioner Better Than the Old

Friday, May 9th, 2014

If you have decided to replace an aging and inefficient air conditioning system, then you’ve already taken the most important step toward making your new AC better than the old one. Your new system will have a fresh start, without any wear and tear to impair its performance.

However, there are other ways to make certain that this new air conditioning installation in Mounds View, MN provides superior performance and energy-efficiency than the unit it will replace. Here are three ideas from our staff at Air Mechanical, Inc. for how to make this next AC a major step up in quality for home comfort and energy savings.

1. Install a high-efficiency system with better SEER

SEER, “seasonal energy efficiency,” is the standard measure of energy efficiency for all air conditioning systems. The higher the SEER number, the less energy the AC drains to provide cooling. Check on the SEER for your current system. If it’s between 12–16, there is definitely room for improvement. Some high efficiency systems have 22 SEER! The higher the SEER on a unit, the more it will cost to install initially. However, if you factor in your potential energy savings over the next 10 to 15 years, you may find that a higher SEER will cost much less in the long run.

2. Install zone controls along with the new AC

Zone control systems permit you to divide your home into separate “zones” (as many as you need) whose temperatures you can manipulate individually You no longer need to cool down the whole home each time you switch the air conditioning on—and that means an increase in savings on your utility bills. Zone control also permits people in your home to adapt the temperature to suit their needs wherever they are through local thermostats. Installers can put the zone controls into your ventilation system as part of the AC installation.

3. Update your thermostat

People often don’t realize how much a thermostat can make or break an air conditioner. If you have an old thermostat, such as a manual model or an older digital model, from your previous AC, you should definitely upgrade to a superior model when the new air conditioning is put in. A programmable thermostat will give you better control over the temperatures and save money, while the next level in wireless thermostats will put the comfort of your home in the palm of your hand: you can operate the air conditioner from your smart phone, anywhere you have reception. A new AC isn’t complete without a new thermostat to make the most out of it.

Ask our specialists at Air Mechanical, Inc. for more ideas on how to upgrade your AC.

When you have new air conditioning installation in Mounds View, MN, go the extra distance so that you have increased comfort and decreased bills for many years to come.

What Are the Differences Between a Honeywell WiFi and Honeywell RedLINK Thermostat?

Friday, May 2nd, 2014

The thermostat is the great secrets of any heating and cooling system for a home. It’s a secret that hides in plain sight: a panel on your wall with a display and a few controls. You probably think of it as simply the location where you can turn the air conditioner and heater on and off and set the minimum and maximum temperatures. If the thermostat is programmable, you can also set the time for it to turn on and off.

However, a thermostat can make or break a comfort system. An outdated thermostat with poor calibration steals away efficiency and comfort, often without you noticing at first. A cutting-edge thermostat with programmable and WiFi power permits you control over temperatures in your home with unmatched precision and complete freedom—which also means unmatched comfort and energy savings.

Air Mechanical, Inc. offers installation of a variety of thermostats in Blaine, MN that will take your air conditioning and heating to the next horizon of technology. Among the available models, we often recommend a Honeywell WiFi or a Honeywell with RedLINK™ technology. Both have superb features, although there are some key differences between them.

Honeywell WiFi Thermostat

With this digital unit, you have access to your home’s comfort through any wireless device. Using a dedicated app, you can set the thermostat’s 7-day program from anywhere you have WiFi access with a simple and easy to understand interface. The Honeywell WiFi is also a “smart” thermostat: it learns your heating and cooling patterns and adjusts itself to reach precision temperatures no early digital thermostat can achieve. It also has an indoor humidity sensor and alters to tell you when it’s time to change the air filter or when the unit detects extreme temperatures.

Honeywell RedLINK™ Wireless Comfort Systems

RedLINK™ wireless technology is an exclusive development from Honeywell available for both commercial and residential comfort systems. It has all the functionality of a WiFi system, but goes beyond with numerous other options through the RedLINK™ portal: over 90 different system alerts, zone control for zone control systems, memory logs to keep track of setting history, a 20-40-60 minute timed ventilation boost, outdoor temperature and humidity displays, and precision controls over staging, fan circulation, and indoor air quality settings. With a RedLINK™, you have total control from almost any spot in the world over your home’s environment available through desktops, tablets, and smart phones.

Choosing a thermostat

Although the RedLINK™ thermostats have many more options than the WiFi, you may not necessarily need all of its extra features. With our assistance, you’ll have the power to achieve energy savings and superior comfort at your fingertips from across the globe. Call us today to explore your options.

Consult with one of our specialists in thermostats in Blaine, MN at Air Mechanical, Inc. to learn about which choices for controlling your home comfort will best fit your lifestyle, HVAC system, and budget.
