"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!"

"As always, Mr. Duct kept in touch before hand, showed up absolutely on time, worked efficiently, and charged a very fair modest rate. The technician also noticed one or two things that we were trying to deal with (other than the furnace) and offered solutions with the equipment on hand. Saved us another call to another place! I'll have then back to clean the a/c and do our ducts (as they've done in past)"

"They were able to send out a tech to repair our AC pretty quickly (within a few days), even though this was during a bout of unusually high temperatures. The tech arrived towards the end of the given arrival window; even though he was still within the window, they called me that day to let me know he would be later rather than earlier, which was nice. The tech diagnosed the issue, and discussed options with me and fixed it (low line refrigerant, possible leak). All that was great, and prices seemed reasonable. The only negative part of the experience is that there was an extra charge to de-ice the frozen interior coils. I could have done that in advance if I knew I was supposed to (the tech seemed surprised I hadn't, or that I wasn't told to). Maybe that's obvious to others, but it's not that big of a deal, just an an annoying extra cost."

"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."

"Hired to clean my dryer vent. I will say the tech who showed up was very nice and he even took his shoes off when he came in. He cleaned my vent from the outside in (which I thought was strange) because I was told he would do this**the technician will disconnect the vent from the dryer machine itself , and then from the inside-out he will clean the vent from lint and everything inside with specially designed equipment only for the dryer vent. If possible he will clean the outside of the vent as well ( If it is not too high in the air exit )** So he actually didn't disconnect the dryer from the inside first, he actually had it turned on while he cleaned it from the outside. 1. I could hear it running and 2. I could hear the alert it makes when it turns off). I could see everything blowing out and all over the place outside, also I heard a loud noise but then nothing so I figured it was just part of cleaning, about 10 minutes later the tech calls me downstairs, the dryer is now disconnected and he told me he found all these broken plastics pieces just inside the vent where the dryer connects. He has no Idea at all what happened or what the pieces are. I go upstairs and google and it looks like the blower wheel broke apart. The tech now reconnects the dryer and turns it on and it makes a loud noise, He says "maybe it's unbalanced" I mean really??! I mean maybe the piece would have broke anyway (dryer 8 years old) but at the very least admit it happened. He had the dryer on previously while he was cleaning and it sounded fine. So anyway I pay him because he did clean the vent, I want to pay CC , he suggests venmo, I say cc is fine , he says he'll have to charge me a percentage for fees, I told him I didn't care, so he goes to put thru card then all of a sudden says he just got a text and the system is down so I have to pay another way...Ok..LOL. So he leaves and I looks outside and there was Lint everywhere! I told him he didn't need to go crazy picking up every piece but he didn't pick up anything, All over my bushes, grass, blew up to my deck. The more I thought about it I decided to email the company with pictures, told I would hear back Tuesday. They wanted to send the tech back so I could explain what he didn't do?? then they gave me this explanation**** *** Technician said that he cleaned your dryer vent from both sides. From the inside - out and from the outside - in. When he touched the hose from the inside out , he found plastic pieces inside of the vent, which he reported right away to you . He believes that those pieces were from a dryer blower ( plastic blowers are rare and this probably means that it needs to be changed ) . Those pieces were already there , generally he doesn't touch the machine itself at all which means he couldn't cause those pieces to be there. As for the mess, he says that he picked up like 95% of it , but because it is kinda picky small stuff and the dryer vent was clogged a lot, so the smaller portion of it was probably blown by the wind around the bushes . He says also that you have seen him how he looked after that and he told you that because of that clogness the blower was putting too much force and probably got overheated and that caused those broken plastic pieces. That is what he said , if you want to have a word directly with him please let us know, or suggest what we should do. Thank you.**** I mean the plastic pieces were already there?? he cleaned up 95 percent?? and I'm the one who told the tech what I thought the pieces were!?? Honestly a manager/owner should take responsibility for his employees and not go back and forth with a customer. Also they state they are BBB accredited and they are not. I advise people to look elsewhere."

Air Conditioning questions, answered by experts

Running a window air conditioner unit costs about $0.06 to $0.88 per hour. Choosing the correct size air conditioner can help it run more efficiently.

AC leaks are common, and an HVAC pro can usually fix them. You may be able to resolve some leaks on your own, but a professional HVAC technician should handle most AC leak repair. If left ignored, an AC leak could cause serious damage to your system or leave you with expensive water damage, usually leading to more costly repairs or replacements.

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.

The difference between a home surge protector and an HVAC surge protector is that an HVAC surge protector is designed to protect the components inside your HVAC unit while a home surge protector is installed near appliances and meant to protect your entire home. There are three tiers of whole-house surge protectors, and they are more expensive to install than HVAC surge protectors.

Yes. Your air supply should be balanced. The return and supply ducts need to maintain that balance, and this only occurs because an equal amount of air should be entering and leaving your HVAC system. Changes in pressure, extreme weather, and blocking vents with furniture or your stuff can make the air supply unbalanced and cause your home to get too cold or hot.
