We have 10+ years of experience serving Pittsburgh homeowners and we can help you too-no matter your heating problem. Don't let the muggy summer weather keep ya down.

We know how bad it is to be stuck without cool air in the middle of a Pittsburgh summer. If you're having issues with your AC, we can help.

It's easy to get swept away in the day to day monotony, even for those that call themselves "pros". When it comes to hiring a heating and cooling technician, nobody wants to deal with being treated like a sale rather than a person, the use of scare tactics instead of education, or someone who just wants to get to job done quickly instead of correctly.
Is it time for a new AC or furnace? Maybe you need major plumbing or electrical work, or worse, you're stuck in the middle of a plumbing emergency and need help now! No matter what it is you need Calfo for, a major installation can put a major dent in your budget.
We see it happen too often-talented and driven individuals start their careers in the HVAC industry with a contractor that passes along more bad habits than good ones. Here at Calfo, we are dedicated to investing our time and energy into our most valuable asset-our employees.
Service options: Check-up (21 points of maintenance) or Tune-up (up to 58 points of maintenance). A Pittsburgh house won't be a home until you can count on your reliable, efficient air conditioning system to provide a reprieve from the humid and hot summer temperatures. If you're in need of a trusted AC repair, maintenance, and replacement contractor, call on Calfo and we will roll out the red carpet for you!
Issues with an air conditioner can lead to some uncomfortable, sticky and sweaty afternoons here in Pittsburgh, and even small issues can turn into big AC problems if left unrepaired, making it crucial to call a trusted HVAC contractor if you think there's something wrong with your AC. At Calfo, we believe in doing a job right the first time, and that's why each of our technicians receives 10,000 hours of industry-specific training.

Techs were great, informed me what they were going to do. Had to do some additional changes due to new code. Old installation was not up to date. On time & did install & finished in a timely manner.

Calfo came the same day I called to check out slow moving bathroom drains. Jason was knowledgeable and explained what I could do to maintain the drains and how to unclog the hair, etc. Jason called and text his pic before he arrived so it was safe. He explained he was fully vaccinated so that helped alot in this time of pandemic. I will refer Calfo in the future!

Rude and unresponsive. Called after my originally appointment to ask a simple question. Never got a return call. Tried to upsell me a part that wasn't necessary. I will not use them again.

Was a great experience so far. Jake came by to talk about a new system since mine died. Was really interested in what I wanted as apposed to high pressure sales. Was a real pleasure.

I like this company. They came within a very reasonable amount of time. Christian was very nice and professional. They also had the part I needed on the truck. Now my heat is back on and I’m happy and warm. Thank you!

Eric was the technician who came to my home to possibly give me a bid on a job. He was smiling when I got to the door. He was very professional, but more importantly he was kind honest and very polite. Everywhere you go these days there are sign "be nice to our workers" or 'do the right thing it only takes a minute". Your company and customers have nothing to worry about because kindness and honesty are part of who he is! It just comes naturally!

Never again.

TL;DR;
Calfo did an incomplete / incorrect diagnosis, costing me $2400 in repairs that fixed nothing. Wanted another $2000 on top of that to do additional repairs. Owner not empathetic to the position I was in; Wouldn't budge on cost. Weird MVP program you must join to get basic things you'd get included anywhere else. I ended up needing a whole new system and had it done by someone else for less.

The Diagnosis and Estimate:
I have electric heat at my house with a heat pump. I called Calfo because my heat pump was not warming my house up whatsoever, despite running constantly

Very professional. The technician (Dom) quickly showed us the issue we were having with our heating and cooling, and we were able to schedule the work to be done the very next day.
The crew showed up on time and had the issue fixed in about an hour and a half.
I'd gladly call them for any future issues (lets hope I don't have to... but we homeowners know these things happen) that arise.

I have had repeated problems with Calfo. Will never use them again. Twice they created problems in my furnace while doing their "free" inspection, and generated huge bills for me. I had other contractors check their work, and found that they had created a problem that they they wanted to charge me big bucks to fix. And, they refused to honor their guarantee after I reported them to the BBB. Left me with a huge bill. Stay away.

I have used Calfo Heating & Air Conditioning twice. Fast, efficient, service, at all hours. I have had the same service technician each time (Jake). He is knowledgeable, highly skilled, and professional! My furnace is old, and I'm trying to keep it going as long as I can. He was able to quickly diagnose the issue and properly repair it, both times. Their rates are reasonable. Based on my personal experiences, I would highly recommend Calfo, and their service technician, Jake. Today is one of the coldest days in years, but I am now warm, and can sleep soundly!

I had first used their website to schedule an appointment for a furnace tune-up, but when no one had contacted me for several days I ended up calling. I was scheduled for service the next day for between 10 and 12. That morning Dylan called and said he thought he might be closer to 12, but then called back to say he would be here by 10:30.

During the tune-up Dylan discovered a faulty part and showed me the old one, a new one and the difference in working between the two. The part was $100 and the tune-up was $80, but for $200 total Dylan performed all the work and signed us up for a spring AC

Even one star is too high a rating for this group.

To make a long story short--they installed a new thermostat in my house on Friday. After Jason left, I noted that it was not working properly. I called and spoke to Tim. They came back on Monday to fix the issue with the thermostat and left me with a thermostat that was not working at all. MY DISABLED SON AND I WERE LEFT IN A HOME WITHOUT ANY HEAT. They DID NOT ANSWER PHONE CALLS OR VOICEMAILS LEFT NOR DID THEY RESPOND TO MY TEXT MESSAGE.

The temperature went down to 24 degrees the last couple of nights and we had no heat until I got someone

I was referred to calfo by an online service, and I contacted them next day to make an appointment. On the day of the appointment, I was running late getting home so I gave them a call to let them know that I would be there. The person that I spoke with didn't seem to know that I had scheduled an appointment. They did show up although quite late. After I described the problem, the tech said it sounded like the control board, went downstairs and plugged the fan output into the 120v in line and confirmed that it was. I was then quoted $900 for a control board replacement. I didn't know

I had exterior line coverage, which contracted Calfo to come out. They relocated and replaced my exrerior water line. Since the city was replacing the main lines in the streets, i had to wait to get the new line tapped in. Calfo left the water line hanging out of the front yard. They never came back or returned numerous messages left.

Once the new line was tapped, i had to have another plumber move my water meter or i wouldnt have had water.

They were also paid to replant the grass, never did. I was told that I needed all these extra valves on my meter to be up to code and i had to pay

We are new homeowners who live within a tight budget and don't have a lot of extra money to throw around. When facing our first problem with our hvac unit we originally went through our home warranty company who sent out an hvac company who turned out to be inadequate to service our hvac needs on multiple visits. Frustrated, we began researching other companies and discovered calfo. They were very receptive to our call and arrived the same day to diagnose our problem. Tim was our service tech and handled the situation very professionally. Our expectations were exceeded. The second time

Had a problem with the heating system at my house on a cold Saturday afternoon. Got contact info for Calfo from a friend who had used them in the past and recommended this contractor. After a brief phone conversation with them they showed up within the hour and quickly fixed my heat. Would highly recommend this company.
