AC Emergencies

There is no better feeling than walking into your home and feeling cool air during a hot summer day.  Simply have a seat and enjoy the cool air circulating around you.

But what happens when your air conditioner stops working? Not only does the heat make you feel uncomfortable; it can also lead to heat stroke, especially when it comes to children. In general, regular maintenance checks and replacing the thermostat’s batteries help prevent any issues over the summer.  The following tips will also help you assess any potential damage quickly and take immediate action in the case of an AC emergency.

  • Check the AC lines and wires of your outside unit. They might be damaged by grass mowers, wire chewing mice, weed whips or any other gardening activities.
  • If your AC has quit completely, be sure and check the breaker.  Especially older AC units use a lot of power, so they occasionally blow a fuse. Simply reset the breaker by turning it off and then on again.
  • If your AC is running, but not cooling the room properly, it’s best to make sure there is nothing blocking the air flow, including checking air filters and compressors. Dirty air filters can easily be replaced and compressors cleaned.
  • Water leaking from your AC may indicate that the drain line is clogged or disconnected. If this is the case, inspect the drain line for clogs or disconnects and clear them out.

When in doubt, please don’t hesitate to call Doug’s Heating and Air Conditioning’s emergency line. Call 309-764-2500 and press #2 to activate our emergency voice mail and leave a message stating the problem you are currently experiencing with your air conditioning. This message is then automatically forwarded to one of our technicians, who will try to get back to you within an hour.

Did you know the temperature of the earth/soil increases the further you dig? Did you know the temperature just a few feet below the ground barely changes throughout the year?  This underground temperature is between and 45 and 75 Fahrenheit depending on your location. Ground source heat pumps, direct use geothermal technologies, and enhanced geothermal systems are taking advantage of these facts to provide clean and affordable energy.

Constant ground temperatures and a system of buried pipes makes all of this possible. During the winter time, these pipes use the soil’s relatively higher temperature to transfer heat into the house; during the summer time, the pipes absorb the heat from your home and transfer it into the ground where it cools down. Further benefits include:

  • Environmentally friendly
  • Potential Federal tax credits
  • Quiet operation
  • Sustainable investment over time
  • Heating, cooling and water heating within one unit

Embrace this traditional way of harnessing Mother Earth’s energy and receive a one year limited warranty on heat pump units and a 50-year limited warranty on the underground pipes. Read more about the different type of technologies here:

A Look Back at Doug’s Heating and Air Conditioning’s History

In the early 1950’s Doug Smith established a small heating and air conditioning business, which he aptly named Doug’s Heating and Air Conditioning. With a focus on exceptional customer service and professionalism, Doug built a winning formula for his Moline-based company that endured until his retirement more than 30 years later.

But this wasn’t the end for Doug’s. In 1985 Matt Hines took over the company. During the following decades Matt and his brothers slowly expanded the business into a team of over 30 licensed and insured technicians, but never lost sight of what was important. Keeping its founder’s dedication to customer service at heart, Doug’s Heating and Air Conditioning grew to continually raise expectations not only in the Quad Cities, but in the surrounding areas, including Clinton, Muscatine, Eldridge, LeClaire, Milan, Coal Valley, Port Byron, Andalusia, Blue Grass, Buffalo and DeWitt

Now, over 60 years later, Doug’s Heating and Air Conditioning has become one of the oldest and most trusted brands in the area. Located on 4307 49th Avenue in Moline, Doug’s team of highly-trained professionals are ready to service your heating and air conditioning needs whenever they arise, 24/7.

When Doug started his company he wasn’t only in the business of heating and cooling, he was in the business of helping people. This philosophy has made Doug’s Heating and Air Conditioning what it is today. Holding decades of experience and a reputation for high-quality service under its belt, Doug’s proud history only gets better with age.

Does energy efficiency matter?

Yes, it does! Energy efficiency not only makes sure your utility bills remain as low as possible, it also has far reaching implications for the environment and the future of our kids.

Energy efficiency starts with the production of energy. Energy plants use coal, gas, sun, or water to produce energy. Making sure they produce the most energy with the least amount of resources makes sure natural resources will last for generations to come and decrease the price of energy. Even environmentally friendly solar power plants require scarce resources which need to be harvested, transported, and processed using energy consuming procedures (silicon). This side of energy efficiency is complex and difficult to impact.

Our homes require especially large amounts of energy to keep us cool during the summer and warm during the winter. We use electricity by utilizing the microwave, washer, lights and we heat water for our shower. Doing all of this efficiently reduces our energy consumption, reduces emissions and lowers our bills. We are directly connected to the plants producing the energy and while we might not be able to adjust efficiency at its power plant source, we are certainly able to do so in our home.

ENERGY STAR provides numerous ways on how to make your home more energy efficient. Prevent heat and cold air from unintentionally streaming outside by isolating your attic hatch and doors. Seal air leaks with spray foam and caulk. Consider purchasing ENERGY STAR certified appliances, including TVs, sound systems, and washing machines. The same applies to electric heat pumps and HVAC systems. The greatest impact in the long term is educating yourself about these possibilities and reading about how a change of habit can save up to 20% of energy (and money), so have a look at and contact Doug’s Heating and Air Conditioning if you have any questions, because energy efficiency and creating a sustainable environment for our children is very much at our heart!

Is my Utility Bill too High?

This is actually a tricky question, because you can only answer it if you know what is normal or average. The first step is to look at past bills over the years and note any changes. Did the bill increase because you have an additional roommate? Did you install new equipment that needs plenty of electricity or are you now using a room you didn’t heat/cool previously?

If the answer to these and similar questions is no, you should look at the rate. Did your energy provider increase prices? Did your agreement change in any other way or are you not eligible for rebates anymore?

If all of your answers are still no, you could look at seasonal changes. If your utility bill has increased during the winter months in particular, the heater might need to be fixed or replaced. If your utility bill has increased during the summer months, your air conditioning might become less cost-efficient due to age or damages. Having the suspects inspected is certainly good advice in this situation. Your local Heating and Air Conditioning expert will help you find the culprit and propose a solution.

Another way of looking at this issue is to compare your bill with friends that live in similar circumstances. These circumstances would include a comparable insulation of homes, similar age and efficiency of windows, doors and furnaces, and very similar heating/cooling habits, though. MidAmerican Energy can help you out with free energy audits in this regard. If your friend’s bill is indeed 20% or so lower than yours, the problem might be a rather fundamental one. Typical suspects are insufficient insulation and old equipment. The solution might be as simple as closing a hole in your ducts. In any case, this is a great opportunity to get informed about insulation and new energy-efficient equipment that can save you money in the long term.

One more way of looking at the issue is to analyze your heating/cooling habits. Are you keeping temperatures the same during the night, although this isn’t necessary? Are you leaving the house in the early morning and return to a freezing home during the summer and a hot home during the winter? A simple change in habit might do the trick and can even be complimented by an automatic thermostat.

Brace Yourself

Air conditioners have been turned off for a while and the winter season is approaching. We are embracing shorter days by getting used to turning on our lights more. Brace yourself for the annual winter adjustment with the following tips;

• Annually check your heating system to make sure it is ready for the winter.
• Replace your heater’s filter and remove any dust to save energy and maintain parts.
• Consider installing a new heating system if your current system is not running efficiently and produces high monthly utility bills as a consequence.
• Consider installing a set-back thermostat to automatically turn down the heat when you don’t need it and automatically turn it up again when you do.

Leaks and Insulation
• Seal leaks frequently occurring around doors and windows. This can save you up to 15% on your utility bill.
• Check your chimney and fireplace and close the damper to disable any warm air leaving your home.
• Inspect your heating ducks to make sure they aren’t torn, crushed, or flattened. Be cautious closing leaks with duct tape – it usually doesn’t last as long as expected.
• Weather-strip and insulate your access to the attic to avoid unnecessarily heating it up all winter long.

The future is here and it’s mini! Mini-splits or ductless units are small and convenient, which makes them the perfect climate control choice for many situations. Unlike your regular heating and air-conditioning unit, mini-split setups for outdoor and indoor units only require a 3 inch hole cut in the building. Due to its versatility in location, the outdoor unit can be placed as much as 50 ft away from the evaporator and this allows for a convenient or an out of sight location for the compressor.

Because mini-split systems are ductless, they will save you money! Ducts, especially the ones located in locations that are not climate controlled (basements), lose up to 30% of energy due to a lack of insulation. This inefficiency costs!

Mini-splits also offer a variety of different styles and location flexibility. Units can be installed on ceilings, walls, or as standing floor models. Most of the units are about seven inches deep and controlled by remote control for user convenience. Not only do mini-splits allow for a more efficient way to cool or heat up your house, but it also improves home security. Because the hole for the unit is only about 3 inches, intruders cannot use them to gain access to the house, unlike through-wall and window units, which allow easy access to your home.

Mini-splits are becoming the heating and cooling unit of the future. Their ability to save buyers money in the long-run, their convenience, and improvement of home safety are just some of the reasons people are starting to use these types of units.
