"My husband carefully spelled out his name and our address over the phone, but the office still got both wrong. But besides that, the service tech arrived early after calling us in advance (much appreciated), found that the drain trap was plugged which prevented the unit from moving into the second stage of the heating process, and he cleared it. We're confident that the problem was fixed, and we're pleased with the work he had done. Jim was personable, knowledgeable, and helpful. But for the 20 minutes he was here, and the limited scope of the work that we could see that he had done, we feel that the charge for our drain line flush of $288 was pretty high. We didn't get quotes from other HVAC companies, and we trusted AWE based on Angie's List's reviews, but on reflection, it seems pricey to us. We will nevertheless call them for annual servicing because they are reliable."

"I talked to Nick who was good enough to send a technician out the very same day that I scheduled the service. The technician, Dan, was very prompt, thorough and friendly. He cleaned and sanitized 10+ vents, HVAC system, returns, supply lines, main line, and the dryer vent which was on the roof. A lot of Groupon deals that I looked around for have up-charges for the requirements that I had, particularly since I live in a 3rd floor walk-up in the city. With Lowe's the price that was quoted was the price that I got! I will definitely use their services again!"

They are very professional, they take the time to explain the work being done, complete the work in a timely manner and were very easy to get in touch with during the process. We were so happy with the work done and we recommend Rams to everyone that is in need of HVAC work."

Heating and Air Conditioning questions, answered by experts

There are two main reasons your furnace and AC are turning on at the same time. The first could be that you’re confusing the furnace with the blower. The blower is located in the furnace and will turn on to distribute cool air from the air conditioner through the ductwork in the home. This is normal. If the actual furnace is turning on at the same time as the AC and hot and cool air are coming into the home, it could be a result of incorrect writing to a new thermostat or new systems.

You can buy a house with a 15-year-old HVAC system if you inspect the system for performance and budget for a replacement within the next three years. You can also negotiate the price with the sellers. Ask to look at the unit’s maintenance records and energy bills for the last two years to determine the shape of the HVAC system and its operating costs. Spend time in each room of the house to gauge if the HVAC keeps the home at a consistent temperature throughout.

Yes. It's not just AC filters that get dirty. Ducts can accumulate dust and dirt quickly. Insects and animals can also get into duct systems, creating many problems. Dirt build-up and unwanted guests can constrict the airflow and cause rooms not to cool evenly. You might also see higher energy bills because they're not working as efficiently.

There are ways to detect a refrigerant leak with several different testing methods. However, most homeowners can figure out something’s wrong with their AC unit by noticing these common signs:

  • Ice forming on the evaporator coil

  • Water leaks near the AC unit

  • Frequent hissing sounds

  • Increased electric bills

  • Unit takes longer than usual to cool

  • Unit is blowing hot air

An air conditioner’s watt usage depends on multiple factors, including the type of AC unit, its size, and how often you use it. With that said, most central air conditioners consume between 3,000 and 3,500 watts. Meanwhile, window AC units use 900 to 1,400 watts, and portable air conditioners consume 2,900 to 4,100 watts.
