"We are beyond happy with the work and professionalism of Porterhouse Cooling and Heating. I called for an estimate and they were out the next day. Then that same day they were able to get us set up for our work. They began the project only a day later. They truly were amazing to work with and supported us throughout the process. We needed a huge job done, because we switched from all electrical to adding gas to our house along with a furnace, water heater, air conditioner, and all new ductwork. We had multiple obstacles that most people did not want to take on. Porterhouse helped us come up with solutions and were very reasonable. They were extremely hard working and did a great job with our house. We love our new heating and air systems! We also have a new thermostat that is wonderful. I highly recommend them for any heating or cooling needs!"

"After the tech diagnosed the issue with the AC. It was determined that I needed to run a new line from the AC condenser on the roof to the furnace in the basement. Seeing how the line within the wall was cut. Not sure how that happened but as a service technician myself I have ran plenty of low voltage wire, cable lines, and Cat 5/6 wiring for internet services. After assisting the tech with running the wires. He wants to overcharge me. I asked him if he normally has customers assist with his work and then charge them extra money for there help. And I had to use my own drill to finish the job. I will not be recommending him for anything. Sorry bro you can keep it moving."

"I noticed this deal of Air Duct cleaning for unlimited vents and called Angies List customer service to ask about the deal and make sure that my one furnace with 3 zones would fit this deal and got all my questions answered; then I purchased the service deal and within an hour or so, I was called by the service company (LOWE'S Air Duct Cleaning Inc) and told that they are working in my area today, and have an opening in the middle of the day since someone changed their appointment; I accepted the time; the service man (Milo) came on time, worked non stop for about 3 hours, where he opened each air vent for the incoming and returned air and cleaned. I have asked for a camera to be used in 3 air vents in order to see before and after cleaning, and noticed the difference. Milo was extremely kind, professional, and worked very hard to get things done in a reasonable amount of time given that I have about 27 air vents and returned air plus 4 long ducts in the basement that are coming from an into the one furnace; The service also included sanitizing and air freshening. I was extremely satisfied with the service, and would defenetly recommend the service to anybody."

"I went from one outlet to three & from a floor cluttered with electrical cords to a clean space. Amir suggested additional outlets because I had created a fire hazard by using a multiple outlet power surger which probably caused the outlet & the power surger to blow out during a storm."

Air Conditioning questions, answered by experts

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. 

The time it takes for an air conditioner to dry fully after cleaning depends on the unit's size and humidity levels. Most units will dry within two to four hours after cleaning, but check the manufacturer's recommendations for drying times. Make sure to leave the unit off until it's completely dry.

If your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.

AC drip pans last five to 20 years, depending on the material. Plastic AC drip pans last five to 10 years, while metal pans can last over 10 years. Plastic AC drip pans are vulnerable to cracking in response to temperature changes. Metal drip pans are prone to rusting over time, which can also lead to leaks.

A few drips here and there should not be cause for concern, but if your unit is leaking a large amount of water, then it’s advised that you stop using it until the problem is identified and a solution is determined. The more you use it during a leak, the more issues it will cause.
