The most important maintenance task that will ensure the efficiency of your air conditioner is to routinely replace or clean its filters. Clogged, dirty filters block normal airflow and reduce a system's efficiency significantly. With normal airflow obstructed, air that bypasses the filter may carry dirt directly into the evaporator coil and impair the coil's heat-absorbing capacity. Replacing a dirty, clogged filter with a clean one can lower your air conditioner's energy consumption by 5% to 15%.

AC air handler buzzing sounds. Do you hear a buzzing sound when you turn on the thermostat? The only thing that comes on in the house when you turn on the thermostat is the fan relay and fan in the air handler or furnace. Try switching the thermostat HEAT/COOL switch to OFF. Then switch the fan switch from AUTO to ON. The fan (only) should come on. If the air handler makes a buzzing sound, it probably has a bad fan relay or, more likely, blower fan.

As you would expect, air conditioning in Portland isn't as expensive as in most areas of the country, owing simply to the fact that most homes don't require particularly large or state-of-the-art units. While our data suggests the national average for air conditioning installation is about $6,000, in Portland we see numbers between $3,000-$4,000, although we've also seen projects as low as $1,500 and as high as $6,000. Heat pump installation is likely to be closer to the national average, but as mentioned, these devices work to be cool your home in the summer and heat in the winter.
This company was highly recommended to us by our realtor. Corey came out to do some work for us and he was really professional. He was on time, and explained everything he was doing and gave a quote (it actually ended up being cheaper!) before he started. He also looked at other stuff for us, and we got the feeling he was being honest and not pushy with his recommendations. We've already booked another appointment to fix some other things, and we requested Corey to do it.
An important component of natural ventilation is air change rate or air changes per hour: the hourly rate of ventilation divided by the volume of the space. For example, six air changes per hour means an amount of new air, equal to the volume of the space, is added every ten minutes. For human comfort, a minimum of four air changes per hour is typical, though warehouses might have only two. Too high of an air change rate may be uncomfortable, akin to a wind tunnel which have thousands of changes per hour. The highest air change rates are for crowded spaces, bars, night clubs, commercial kitchens at around 30 to 50 air changes per hour.[17]

If your compressor doesn’t have an overload button and you hear it humming or buzzing, poke a screwdriver or stick down through the top grille and try to spin the fan blades clockwise. If doing this gives the fan enough of a boost to get it going, the unit has a faulty capacitor that must be replaced. See How to Test and Replace an AC Run Capacitor, above.
Air conditioners improperly installed will develop air duct leaks and low air flow. Your air conditioner looses its cooling power in hot weather. A lack of maintenance will cause your air conditioner to malfunction. Refrigerant charges and compressors are some of the parts needing regular maintenance. Regular maintenance increases the lifespan and production of your air conditioner.
You’re constantly repairing your HVAC: If your heating and cooling system has needed repairs more than once or twice in the past few years, it may be time to take the leap with a replacement system. The money you spend repairing older equipment can often be better used towards the purchase of newer, energy-efficient HVAC systems. Here’s a simple guide: If your labor and parts cost upwards of $1,000, look toward replacement. 

One of the most important ways to maintain the efficiency of your air conditioner is to check on its efficiency periodically throughout the year. In addition to changing your air filters every three months, having a professional heating and cooling professional service your air conditioner before the peak of summer ensures you're not overlooking potential problems. The thorough inspection and tune up of your air conditioner is well worth the low maintenance cost.


In 1906, Stuart W. Cramer of Charlotte was exploring ways to add moisture to the air in his textile mill. Cramer coined the term "air conditioning", using it in a patent claim he filed that year as an analogue to "water conditioning", then a well-known process for making textiles easier to process. He combined moisture with ventilation to "condition" and change the air in the factories, controlling the humidity so necessary in textile plants. Willis Carrier adopted the term and incorporated it into the name of his company.[10]
We’ve found that many homes and businesses in Atlanta face significant indoor air quality issues as a result of the seasonal high humidity in our area, which creates conditions ripe for mold and mildew growth in both old and new HVAC systems. Our HVAC technicians can help you determine which strategies will work best for neutralizing airborne particulates in your home, which often involves a combination of filtration methods and ultraviolet light technology that together can help keep your system perpetually free of contaminants. We can also install whole-house dehumidifiers and humidifiers, which can make a huge difference in the amount of work your HVAC unit will have to do to be effective.
Maintaining your air conditioner (HVAC) unit will ensure that it’s ready to properly cool your home all throughout the summer. Keeping your unit in good condition is also important for your wallet: lack of maintenance shortens a unit’s lifespan by 10-15 years, meaning you’ll need to buy a new one sooner. Lack of maintenance also results in a 5% efficiency loss, which results in higher energy bills. 
With winter on its way back to Atlanta, furnace and heating repair may not be the first thing you think about, but maybe it should be.

Day or night, our HVAC experts are here to ensure you have a comfortable home, and can help get your furnace back operating in almost no time.

In 2006, a new HVAC rule went into affect for residential air conditioners, requiring all to have a Seasonal Energy Efficiency Ratio (SEER) of 13 or higher. As you might expect, the more efficient the unit is (or newer), the lower your average AC repair cost will be. Keep in mind, if for some reason your high-efficient repair bill is high, you’re still saving on energy costs every month through your electric and gas bills. 


After one company just took a cursory glance at our A/C and found nothing wrong, I called HVAC. I called them mostly based on Michael W's post on 8/10/14 where he told us the owner, Alberto, took his feedback and took it SERIOUSLY. That speaks VOLUMES to anyone who has been around long enough to know the characteristics of the serious players are and those who are the wannabes.
"Friendly, professional, responded quickly to my problem. I have called many air conditioning companies about my problem including the maker of the unit and had come to the conclusion that I would not find someone to repair this unit. D's came in and within a short test found the problem and assured me of a fix. They made the fix within 2 days as they needed to get a part and they also checked to see what the cost would be of the fix by putting in the control boarrd from the maker which was very high to the extreme. I now have a unit working and am very pleased."
It can be hard to make the decision to replace or repair your AC unit. However, in many cases, homeowners call in HVAC professionals to check their units and provide a second opinion. A technician can tell you if there’s plenty of life left in your old air conditioning unit or that it’s time to let it go and get a new one. Your HVAC technician may check out your home’s insulation quality, too. You could increase your system’s effectiveness by improving the insulation.

Change the filter: A new filter can cost as little as $20. Since this is the most effective way of maintaining your AC system, there is no reason not to change your filter. Homeowners should change your AC filters whenever it gets dirty. Depending on the filter, you may have to change it once every six months or once every month. Each filter should indicate how long it will last.
"Customer service was great, and the price was in-line with other places, and fast service. We had a whole replacement of the outside and inside. I would have liked to see a better install for the furnace and new thermostat - the new thermostat should have gone where the old one was, and even tho the new furnace was a tight fit, they didn't offer to come back and repair the case molding, or give me a discount on the damage done, and I believe they should have put a disconnect box on the outside of the home, to make it easier for any future repairs needed. Other than that, am very happy with the cooling and heating!"
