My wife and I had been looking for someone to service our HVAC as new home owners. We looked around local forums and saw countless recommendations for Pat. With our HVAC now working and enjoying the cool inside air, it is clear to see why. Friendly, knowledgeable, reasonable, honest and no pressure. We'll be calling him for any service we need in the future.

Pat was awesome. My sister and I have been using Pat for years. We finally needed a new HVAC. He's prompt, he wont rip you off, and will work around your schedule. We will continue to use Pat.

Our AC went down in the middle of the latest heat wave and we needed it fixed fast. I had never used PSD but based on their reviews I gave them a call. They lived up to their ratings and more. I called and Pat came right out. Diagnosed the issue within minutes and had our AC running within an hour of my call. Additionally he explained exactly what broke in an easy to understand way as well as breaking down the cost to repair. I have found our go to HVAC company and highly recommend them.

I have no words on how strongly I recommend using Pat from HVAC problems. I had DE Duffey & Sons come out for spring AC tune up and after finishing the job, the technician informed me that there is no freon in the unit. He told me that he couldn't find the leak, so he filled nitrogen in the unit for now and someone from the office will call me. Without even explaining the whole situation and solutions, he just left. Later, two different technicians came out twice, but they couldn’t even find the leak. They simply told me to change the whole unit and quoted me approximately $5000 just for the unit plus labor, freon and tax. I was really annoyed at their solution because my unit is only 6 years old. In short, my experience with DE Duffey was not great because I was always kept uninformed, and they were looking to charge me for a leak they couldn’t find. So, I reached out to Pat and explained the whole situation and he was really surprised by their solution since my unit is only 6 years old. He came out and diagnosed the problem and was able to find the leak within 20 mins. One thing I really liked about Pat is that he was upfront about his charges and would ask multiple times before touching the unit. Unlike DE Duffey, he would communicate and teach you about the system. Once he changed the valve, he recharged the unit, and the unit was working like brand new within an hour. It’s been a week and I literally have no problem with the system. Pat even reached out to me to see how the unit is doing. The whole thing costed me $1175 (diagnostic, part, freon and sealant). Meanwhile, it would have cost me approximately $8000 if I would have gone with DE Duffey & Sons. Please reach out to Pat if you are looking to get unit fixed in a timely manner without paying unnecessarily thousands of dollars. Pat is a pro, and he knows what he is doing. He would never trick into spending more just so that it would benefit him. Pat is the guy!!!!Update (07/18/2026):We had another emergency and Pat came in the next day to fix the issue. He is still our guy. He checked on the system the next day to make sure everything was running properly. I highly recommend him.

Called Pat out of the blue after searching for a local HVAC company to check central AC unit.He came out the very next day (Saturday).Quickly evaluated the system, isolated the issue, repaired it and cleaned everything.Could not be happier.

I came home from vacation to a broken AC and needed help fast. After seeing nothing but 5 stars for PSD, I gave them a call and quickly understood why they are so highly rated. Pat was at my house shortly after I reached out to him, and my AC was running again in no time. The service is friendly and transparent, and Pat followed up with me the next day to make sure my AC was still running well. I can’t recommend PSD enough for heating and cooling needs!

Absolutely excellent service! Clear and direct communication, fair pricing. Thank you for such prompt and thorough work!

Day after Fourth of July, My air stopped working. Pat was very responsive and was able to squeeze me in. Best Hvac Repair service I’ve dealt with! He’s honest, not pushy, and is very genuine. Would recommend him to anybody!

Quick response. Kept me updated as he performed repairs.

Great service, Quick and efficient. I would recommend PSD to anyone looking for a true professional

Pat was great. Same day service, he squeezed me in during a heat wave. Work was done professionally and timely. Upstairs AC unit working much better after comprehensive fix. Thanks PSD!

Had my A/C break on a 90 degree day and Pat was able to show up within a few hours. Had everything fixed quickly. Great communication and very easy to work with. Highly recommend.

After our AC in the house we just moved into wasn’t working properly and a week of high 80’s temps was coming, I quick went to Google to find the nearest Heating/Cooling company. PSD stood out by the 5 star reviews and how great Pat was at his job.We called Pat this morning (Tuesday) and he showed up same day a little after lunchtime. He explained the fix and was very kind and friendly to our family, including my 2 year old son. Our AC is working great again!If you are looking for someone new to fix your AC or Heating system, call Pat! I will be calling him in the Fall to service our heating system!

I called Pat’s Service thinking my heating system wasn’t working, but he quickly determined everything was functioning properly. He took the time to explain how my gas furnace and cooling system operate and performed a much-needed maintenance tune-up. I appreciate the honest assessment and quality service. I would definitely recommend this small business and will be calling again for future needs.

This is the first time I used Pat. He responded very quickly to me wanting an AC tune up. His service was very good and answered all my questions. Also, he installed a WiFi thermostat that I bought.I will be using PSD for all my HVAC needs.

Professional Timely Responsive Fair Prices.Highly Recommended.

Reached out to Pat around 6pm to come take a look at our heater that was producing heat on and off. He came the next day and diagnosed the issue. Within two days, the problem is fixed and our heater will last us a little while longer. Such a relief during this awful cold weather. Highly recommend PSD! Thanks so much, Pat!

We woke up with no heat on Wednesday, January 21, 2026 shortly before the major snowstorm hit us on Sunday. I searched for local HVAC companies in need of a quick response. The result included all the big names you see advertised on TV. After reviewing several options, I worked my way down the list. After reviewing 10 to 12 names, I found PSD Heating and Cooling. I decided to contact PSD Heating and Cooling because of their excellent five-star reviews and their location in the Schwenksville area.I can confirm that the positive feedback I read is entirely accurate. Pat answered my call and arrived at my home within an hour and a half. He clearly explained my options regarding repairing versus replacing my older furnace, diagnosed the issues, and walked me through the necessary corrections.He completed the repairs in under two hours, and our heat was fully restored. Pat is honest, reliable, and provides fair pricing. We are very satisfied with both the repairs and his professional assessment of our situation. We will definitely use his services again and highly recommend PSD Heating and Cooling to others. Thanks, Pat!

Called ahead before appointment and on time. Neat and couteous.

Pat has been one of the best things to come into our home since We moved into it back in 2022 with an original unit from 1993. Imagine calling a number you got off google for help and he comes that same day within 2 hours. He is reliable and trustworthy and honest. 4 years living there and we never want to or have to call anyone else. He doesn't break your bank, my wallet is happy when he leaves and even better, he has not once pressured us into changing our original unit even though its usually the same problem when we call him. we plan to change it this up coming year or next as recommended and Pat will be the one we call. Thank you for all of your help over the years and we look forward to giving you our business when needed!

I woke up on 1/2/26 with a 60 degree house. It’s just me and my 4 year old daughter. I was given a bunch of suggestions on who to call but something told me to call PSD and so happy I did! Pat was at the house within an hour and 15 of my call to him. And my unit was repaired (thankfully a quick fix) before 230 that same day, and my daughter came home too a warm house. Thank you, Pat and cannot recommend enough! Honest, up front!

Pat made our family’s broken heating unit a priority with quick service and great communication. He was very knowledgeable and we will definitely be using him in the future should any further issues arise.

Pat is an amazing guy. Very talented and honest guy. He is upfront with his charges. He won't force you into buying unnecessary service. This is the second time we are using his service and we are very impressed by his skills and nature. Highly recommend using him.

Reached out on a Friday and came the following Monday to fix our issues perfectly. Wore foot protection and laid down a blanket to keep the are clean too which was a huge plus for us. Definitely recommend!

We noticed an issue with our AC unit on Thursday, called Pat on Friday late afternoon and he was out to our house on Saturday morning. PSD was referred to us by our neighbors, and they were spot on— on time, communicative, professional, efficient, polite and reasonable prices. Our compressor broke and Pat was able to explain the issue and repair it within the same visit. HIGHLY RECOMMEND. Will be making an appointment to service our heater before the winter months. Thank you, PSD!

My family and I returned from vacation to an air conditioner that was not working. Reached out to Pat and he came a few hours later, diagnosed the issue and fixed the problem. Pricing seemed fair and very happy with the experience. Looking to use Pat and PSD as our yearly hvac company for maintenance and tune ups.

Pat was great with diagnosing my AC issue and resolving it quickly. Very professional and friendly. Will use him again

Pat of PSD is a no-brainer to use for HVAC services. I mean that honestly. I love supporting local, honest, knowledgeable companies and having full confidence in their services- PSD is just that. You should have NO hesitation using PSD because their service is EXCELLENT and their pricing is FAIR and their response time is IMPRESSIVE. Thank you!

June 21, 2025.I’m writing this second review for Pat.I turned my air conditioning on two days ago for the first time. It ran through the night, but could not lower the temperature much at all. I called Pat at 11:45 AM and he started troubleshooting the unit by 1 PM.This was an actual godsend at the time due to the fact that I was having severe nausea and violently threw up about 10 times in 3 hours. The last thing a person needs when they’re nauseous is to be overheated.In addition, my recent EKG showed that I had a heart attack. I had an echocardiogram done as well. Some abnormalities did show. I'm 58 and not in good aerobic shape. I was too sick to drive anywhere. The fact is I could have had a heart attack if I didn't get my place cooled soon.It turned out to be a pretty common repair. It needed a capacitor, AC refrigerant recharge, as well as some sealant.Pat's work is honest, thorough and high-quality. Most importantly, He treats people with respect and his pricing is as far as any company out there.My heater died last Thursday evening. I spoke with an HVAC pro the next day that had installed a new system for my neighbor a couple years ago. He actually quoted a higher quality unit then the one I currently have (age 21 years). I verified the $6800 out the door price for my one bedroom condo was not only competitive, but below market according to a friend who had his own HVAC company for many years.When I asked him about fixing the unit he said he doesn't really get involved in MacGyvering broken units that are that old. At the same time he tells me that if he installs the new unit it would be his "baby" and he would guarantee it and service it. This completely confused me.I figured instead of MacGyvering it, come out like a Pro and try to fix it like Pat from PSD Heating and Cooling in Schwenksville PA did. I called Pat on Friday morning and he was able to schedule a $75 service visit first thing Saturday morning. He said parts would be additional but that was all.He showed up on time and wore booties although I already had drop cloths laid over my carpet. He diagnosed it immediately as being the fan motor capacitor and he went to his truck to get one. He was done in 15 minutes for only $225 my problem was solved and the heat was on.He said that because I turned off the heat as soon as I smelled a burning smell I likely salvaged the blower motor.The quick math would tell me he saved me $6600. I've already referred him to 2 of my neighbors and he's coming out in 2 days to tune up one of their systems.Quality, honest work is difficult to find. I must say I chose Pat based on internet reviews and the fact that he's not a large company. He's the owner and he came and did the work himself; not some kid a couple years out of trade school.I am extremely grateful for what Pat did for me after just having to replace a fridge and a water heater in the last 2 months.

Great Communication! Right on time. Fixed issue within an hour. I def recommend
