Replace the coil in our AC unit quicky and did a great job.

John
The guys that installed the HVAC were total professionals. Would definitely rehire!

Parks and leaves their van illegally on the street and unattended for over 40 minutes so a mother can’t get by with her newborn and toddler. This business does not support mothers and families. Do not use them.

Caitlin L.
I’ve used Cardullo for over a decade both professionally as a realtor, and on my personal home. Cardullo maintained/repaired my previous HVAC to last 30+ years and he just installed my new HVAC. My compressor is on my roof and his team worked hard to get the new one up there! His family owned business is professional, kind, detail oriented, and very fairly priced. I will continue to use Cardullo on my personal home and refer his business to all of my clients. Thank you, John!

Elizabeth M.
John and his crew were great from estimate to install. Highly recommend them!

Matthew B.
Excellent installation of our new 3.5 ton AC and 96% efficient furnace system. The crew was on time, focused on the work, polite and respectful of our home. The complete install was done by noon! They left the place spotless. John was responsive to questions with clear no-nonsense answers. Professional service at an excellent price. Highly recommended.

Cardullo Mechanical has supported my gas and oil heating repairs and equiptment replacement projects for years. They are my first call every time!!

John S.
My central air and heat system needed complete replacing on my second floor when it was 95 degrees! The air unit was on the roof, but that wasn't a problem for them! John and his crew came right out to assess the issue, and were able to get everything replaced and air unit up and running perfectly! They were courteous, clean and efficient, and the pricing was very fair! I wouldn't hesitate to call them for anything you need!!

Frannie E.
My Central A/C was down and the Cardullo Team came to the rescue. They had us back up and running immediately. Employees are extremely polite and knowledgeable. I highly recommend John and his team for fast service and phenomenal pricing. Customer for life, thank you!

Frederick H.
A friend recommended Cardullo Mechanical and they have become my go-to for all HVAC work. Today, for example, when my old hot water heater started leaking, John got back to me promptly, gave me a fair quote and within a few hours, his team had replaced the heater. Friendly, respectful professionals.

Brett S.
Amazing amazing amazing. The most fast and the best price. So transparent and straightforward. Easy to communicate with

Lisa C.
I am so grateful to have found cardullo for my under warranty hvac part repair. They were quick, easy to get on the schedule and fair price (another co quoted me 4x what they did!) and I could trust their knowledge and expertise as they are not salesmen.

This is my third major job with Cardullo and I recommend them highly. They are reliable- reasonable, honest, accountable, and really the best of the best.

Josephine R.
One of my AC units was running but wan’t providing cooling after turning it on for the first time this cooling season. As they are a local business in South Philly, where I live, and had nothing but positive reviews, I called Cardullo Mechanical in the mid-morning on a Friday and was able to speak with someone directly without having to leave a message in the hopes I would get a call back at some point in the unknown future. About 2 hours later, that same day, Cardullo sent 2 mechanical technicians, who were both respectful and consummate professionals from the moment they stepped foot into my house right until the time they left about 90 minutes later. They trouble-shot my issue and were able to address it right on the spot. They took the time to explain the issue to me and we discussed my options. They were also able to also give me an estimate of the probable costs for my service that were right in the ballpark when I received the final invoice. Overall I was extremely impressed with my experience with Cardullo Mechanical and I will be calling on them again for my future HVAC needs.

Paul D.
This company is incredible. I got a new boiler and couldn’t be happier. This company does not try and feel you out to Inflate the cost. They give the best quote first, and their prices are extremely reasonable. The workers are very courteous, Knowledgable, and professional. I will be using this company for the rest of my life.

Joe F.
I’m fortunate to have Cardullo as my go to heating service company in South Philly. The guys are incredibly attentive, transparent, genuinely friendly, and quick to come when I have had heating issues. My prior heater was severely damaged from improper installation (different company) and within about two days, I had a brand new heater up and running. I can’t recommend the Cardullo team enough. If you need heat servicing, I strongly encourage reaching out to them.

A D.
I have have multiple experiences with this wonderful company over the years, both with heating and air conditioning. My first experience was when my air conditioner stopped working and someone came to fix it on the are so reasonable. I’m not the kind of person to gush but this company is deserving of gushing. My highest recommendation!

Janet T.
Experienced work force and very efficient and no problem working around my schedule. Great guys and will be using them from now on for all my HVAC and A/C maintenance from now on. It's nice to know their are some services out there that our honest and don't squeeze you for a payment before they hit your door.

Winnie D.
Furnace died (after 20+ years) and Cardullo Mechanical was recommended by a friend. They quickly responded on a Sunday, showed up the next day when they said they would, and installed the new AC & new furnace 2 days later. They also gave me the fairest quote without any upsell. Installation team was great. Already recommended to multiple people.

Doria S.
Had CO gas in our basement after Gen3 installed a water heater in our basement and didn’t take into account the exhaust from the furnace all going through the same pipe to the outside. Cardullo Mech helped find the issue and resolve it by installing new PVC piping. Will be going to them for my HVAC needs from now on

Charles S.
My system is only 4 years old...the original installer (McKennas Heating HVAC) has not lived up to their warranty or maintenance. John called immediately and sent his guys out...friendly ..great..knowledgeable.. Had my system working within 1/2 hour. I highly recommend using this company for boiler/steam heaters! PGW was here the entire day yesterday only to put a yellow tag on the system to not run it ! Thank you guys so much... You are awesome and I'll be seeing you for maintence yearly.✌️

Donna C.
One of the most professional, friendly, on-time and extremely reasonable HVAC companies I have ever had the pleasure of doing business with. Cardullo’s technicians were very thorough in troubleshooting my unit, and provided all applicable options to solve for my heating issues. I would highly recommend this business for any HVAC system issues or concerns.

Kristy K.
Excellent service with great value. I needed my condenser moved and they were able to take care of it quickly, although it was a little hard to get hold of them initially

Maria R.

This is the only company to call for your hvac,ac and heating system needs..theyve always had a great reputation and my recent experience was right on point ..Clean Work done with integrity and the price was fair..this is a family run business that delivers that old school Customer service you can trust..

eric G.
Had an issue with my furnace after hours. Called Cardullo Mechincal, they diagnosed a dirty flame ignition sensor and walked me through how to fix it over the phone. Would highly recommend!

Thomas S.
I’ve been meaning to write this review for over a year. Last year after going through several frustrating companies with my home warranty. I found Cardullo mechanical and they were extremely responsive and came out the next day diagnosed the problem that every other company missed and promptly gave me an invoice and came to fix it within the next few days. I cannot thank them enough for their professionalism and also how kind they were and swift in doing the work. The cost was extremely extremely affordable compared to many other people in the city and one year later the system is still doing well.

Uche U.
Heat didn’t come on for the first cold day of the season and two friendly helpful guys showed up quickly and fixed the problem quickly. Nice having such good local service.
