"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."

"AWE promptly responded to my work request and kept me informed about my appointment status. Peter came to perform the work. He was very thorough and even discovered that the HVAC contractor on our new home installed 2 furnaces: a current year model as well as a prior year model that was more prone to breakdowns. Provided great information and would definitely hire again. Thanks!"

"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!"

Heating and Air Conditioning questions, answered by experts

On a summer day, expect your AC to run between 12 and 16 hours. However, this time frame depends on just how hot it is outside and the comfortable temperature you’re hoping to maintain indoors. Assuming the size of your AC is appropriate for the space you’re trying to cool, it shouldn’t be a problem for it to work this many hours.

Deciding whether to replace just the AC coil or the entire system depends on the age of your unit and the overall cost. Replacing a coil is less expensive than a full system replacement, but it can still be a pricey repair. If your HVAC system is relatively new and still under warranty, or if the replacement cost is significantly lower than a new system, replacing the coil can be a worthwhile investment that restores efficiency and extends the unit's life. However, for older systems (nearing the end of their 10-15 year lifespan) or those with extensive damage, it is often more cost-effective to replace the entire AC unit. Mismatched coils in an older system can lead to inefficiency and future breakdowns, so a full replacement ensures optimal performance and avoids further costly repairs.

The cost to replace an AC evaporator coil is typically between $600 and $2,500, with an average cost around $1,300 to $1,350. The price of the coil itself can range from $550 to $1,100, depending on the brand, size, and style, with professional labor adding around $700. Replacing a condenser coil is generally less expensive, costing about $800. Because this repair involves handling refrigerants, it requires a licensed AC professional. Regular inspections, which cost between $200 and $600, can help prevent costly coil replacements.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.

Assessing location for airflow, convenience, and minimal noise impact.
