Company Overview

We offer installation, repair, and maintenance for all brands of HVAC equipment and plumbing products. Call us today for a prompt, no-cost quote, or submit our straightforward contact form online to find out how Calfo & Haight can assist you.

We design and implement our own ventilation systems (sheet metal ductwork) when installing a new unit to ensure compliance with codes and while performing HVAC work in new builds. This ensures that the installation is executed flawlessly and may save you money.

We replace hot water heaters, featuring modern tankless options, set up new water and sewer services when required and resolve any plumbing challenges you have, from leaking pipes to toilets that continuously run. We can also install any needed fixtures.

Back in May 1967, Augustine ""Augie"" Calfo and Donald ""Slim"" Haight established Calfo & Haight, Inc. Initially, there were three team members: Augie, Slim, and Gerry Calfo (Augie's wife). Gerry handled the phone calls and finances. As demand grew, so did the team size. Eventually, Augie's children joined the company, with two of them, Nick and Dawn, contributing to the company. Augie's oldest grandson also entered the plumbing field and came on board.

We are known for our integrity and approachability with customers. We take pride that we still serve some of the same customers.

While Augie and Slim are no longer with us, Nick, Gerry, and Dawn carry on the tradition. We employ long-time plumbing and HVAC technicians handling the fieldwork. All of our staff are treated like family, which is why they stay with us for many years.

This is the first time I have EVER written such a negative scathing review of a contractor, but I am doing it because 1) they are supposedly a 5-star plumber and 2) they totally diss'ed me this morning. I contacted them almost two weeks ago, but they could not respond before I went away, so we scheduled their visit to my property for today. They contacted me yesterday to confirm the appointment that we made about 10 days ago. I was impressed, and I thought I had finally found a reliable plumber to take care of my 18 rental units around north Wilmington, DE. We discussed the appointment and I was told that they would be there at 7:30 AM. That's a little early for me but since I was the first call for the day, I set the alarm for 6:00 A. I arrived at the location at 7:20 AM and proceeded to prepare the work site (i.e. Open basement Bilco doors, hook up garden hose to wash off their equipment after clearing the sewer line, etc). I then sat in my car and waited, and waited. Finally, at 8:00 AM I called their office and after being told maybe they stopped for coffee, I reminded the lady that it doesn't take 1/2 hour to get coffee. She put me on hold for about 1 minute then came back on to tell me that one of their plumbers didn't show up for work today and could we reschedule the appointment for tomorrow... Needless to say I cancelled the service call and told them that I need a company that's more reliable than them. Fortunately, it wasn't an emergency problem, but be forewarned that this plumbing company is totally unreliable and must fall apart when JUST one plumber doesn't show up for work. Since it's impossible to give negative stars, I had to give it one which is 5 times better than they deserve.....

I was in need of HVAC services for my business and had called locally for several quotes. Calfo & Haight responded immediately (first). Their quote was detailed and fairly priced. Their representatives professionalism gave me confidence in the organization as a whole and I chose them. Their crew was incredibly professional and work quickly and respectfully. The job was done perfectly, quickly and on schedule. I've since used them again and received the same level of service. They know customer service and quality. These guys are reals pro's and they ""get it"". In fact, a friend of mine who is in the HVAC business referred me to these guys... That says a lot.
