"Porterhouse Heating and Cooling was very professional and knowledgeable on the service provided. I used them to install my air conditioner unit. Eventhough, the unit was not my issue, they still came out and was able to find the issue and fix it. They were friendly, professional, and reasonably priced. I will definitely use again for any of my HVAC concerns."

"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

No, it isn’t necessarily bad to turn your AC on and off frequently—contrary to popular belief. Even if you stop and start your AC throughout the day, it won’t use as much energy as it would if you ran it nonstop. 

If you’re concerned about your power consumption and energy costs, there are a few simple ways to use your AC more efficiently. Regularly cleaning the filters, scheduling routine maintenance, and using a programmable thermostat are all great choices.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

Fixing a leak in an AC unit costs $200 to $1,600, depending on the type of leak and any related damage. But depending on the age and condition of your AC, it might make more sense to replace the AC unit instead of repairing it. If your AC is only a few years old and relatively problem-free, then repairing it is the right call. But if it’s nearing a decade old and has other issues, consider replacing it.

A 3-ton AC unit is probably too big for a home that’s 1,200 square feet. If you have a 1,200-square-foot home, you likely need a unit that’s somewhere around 1.9 and 2 tons. An AC unit that’s too large will be really inefficient and cost you a lot of extra money on your bills. 

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours.
