Recommended Customer Reviews

I was out of town and my husband called this company to replace a kitchen faucet. We already had the new faucet purchased, so it was just an install. They charged us $502 for an hour and a half of work during normal work hours (and after showing up several hours late). That's $335 an hour for labor! Outrageous and predatory.

As of 6/5/25, I s/w Beth in their front office to find out that their Service Manager Teri Ritz had put a notice on my file to stop doing business with me. Taking into account I had a VIP membership with them purchased April 2024 that was supposed to last 3 years offering check ups on AC and furnace each year. I asked to have my VIP membership prorated for a refund or another resolution and Beth told me she would speak with Mr. Calfo (owner) and get back to me. Not surprisingly, that call never came. After research, I have found this is a common practice of the business to inflate the cost of a part and waive it to make it seem like their VIP membership will be a good value. They invoiced a hot surface ignitor for my furnace at $375.13. Further research shows this part to have a value of around $35. This part took 10 mins to install and resolve. No written notice was ever sent to me stating that my VIP membership was being cancelled. This cancelation of my VIP membership occurred because I had the audacity to ask for a refund of a service call performed by another furnace company after Calfo's technician in Nov 2024 tried to scam me into replacing my furnace. I had a warranty claim on the Carrier furnace of the heat exchanger which Calfo refused to handle because they don't affiliate themselves with any furnace manufacturer. A Carrier service tech could not find fault with my heat exchanger to perform the replacement for a warranty claim. I then had to pay a trip charge for his time. I went back to Calfo to get this money back and Teri Ritz refused. I then escalated my request & asked for proof w/ their invoice that showed the heat exchanger was bad. Their service tech could provide no evidence and after about a month delay, I received a refund for the trip charge of the other company.

Please be careful with Calfo. I had them out to repair my furnace, which they said I needed a new heat exchanger and it was not worth repairing, I also added an air conditioner and a hot water heater for a total of $16,500. On doing some searching, the items were overpriced and my daughter found another company that came, got my furnace running and found that the heat exchanger was under warranty. I immediately contacted Calfo to cancel my order within two hours. I did sign a form on a cell phone with my finger that said supposedly had the restocking fee quoted but was too small for me to see. I gave Calfo $8000 and they want to keep $5200 as a restocking fee. Also the invoice was vague and did not mention specific products, only listed generic. The new repairman said the water heater at $2400 was twice the average price. Dishonest business practices...beware.

Calfo installed a gas furnace for me through the weatherization program. At first the air wouldn't work, the ducts were completely blown apart, I called them back, they came out 4 days later and taped it all together. My stove and hot water heater were not working properly so I called another company out to check it. There were gas leaks. The leaks were small, but I prefer no gas leaks. There had been 2 inspectors in prior and there were no leaks prior to the furnace installation. The lines were old though.
They said all the line needed fixed (this is true) but needed to submit a estimate to make sure they would get paid to fix it. So I sat and waited 2 weeks with a few gas leaks until they came back.
Ultimately I have a 100% efficient furnace and all new gas pipes that are working properly. I got this through action housing, so even though I had to make a dozen calls i consider myself pretty lucky.
Even though I complained and they had to come out 4 times for what was a 1 trip job, everyone was courteous and respectful. Both myself and my property were treated with respect. Ultimately if you aren't up for a lot of follow up avoid like the plauge.

If only I could give a zero...
What began as a simple furnace maintenance check on a fully functioning unit turned into this:
1) Tech stated the pressure switch was bad and that would cost $500 to fix. I authorized repair as I initially trusted them and was worried about having heat.
2) Tech then informed me that he made a mistake and this didn't need replaced so that would be free (obviously)
3) Tech then claimed that it was the induce draft motor and this would run ~$1200-$2K. Since my furnace is older, I asked questions about cost of replacement vs repair. Tech stumbled around answers, wouldn't give me one. Didn't really seem to know much or just didn't want to answer me. Stated he would call with quote. Also turned off the gas ""for my safety"" and disabled furnace.
4) Today I was quoted $20K for the ""low end""
Called other folks for quotes.
A very kind man who owns his own business arrived and this is what I learned:
1) pressure switches rarely go bad and can be easily checked. If this part was bad, it costs $32 and is a simple two wire install. $500 quote was a complete rip off
2) The furnace turned on and functioned easily. The induce draft motor is wearing but not broken. Also informed that the cost of repairing this would be a few hundred, not $2K (scam attempt #2)
3) There was no reason to turn off my gas.
4) Entire inside of the furnace was examined. Minimal rust, no cracks.
5) A full replacement would be less than half of the outrageous quote from Calfo but not warranted since my furnace is working.
Grateful that there are still good humans. Clearly not at Calfo.
Shame on you Calfo.

Never again... They are literally charging us a 35% restocking fee for a part that has not come in yet, and that they have no idea how long it will take to come in.
We assumed the part would only take 5 days to come in from what their tech said, but now we have no idea how long that will be since they have no idea when the part will show up. So we cancelled.... just avoid this company.
Any other legit business wouldn't have business practices like this.
Update 8/12/2024: Owner Tim refuses to give us the refund they legally owe us due to seeing this bad review.
Do not give this company your money.

Calfo is a complete scam! Asked for a bid for a simple 12,000 mini split install. Nothing special, no complexities.
A top of the line unit from Mitsubishi runs about $2k, would require no more the $1k of labor.
Calfo marks it up $5k or close to 2.5X and then tells me I'm the dumb one. DONT waste your time with these people!

They came quickly to do my repair. The replacement of an outlet near my pool, and grounding my pump, cost over $500. I was told the repair person would give me an estimate for another job--it's been 3 weeks, no estimate, and no contact from the company.

This company came out and intentionally sabotaged my AC unit from further work or further repair.
Ryan S was the tech that came out. He installed $700 worth of parts and tried to get me to pay over $800 in parts plus the visit and those parts didn't fix the unit, which I didn't agree to paying for those parts when the unit wasn't fixed. He told me the compressor was bad and I needed to replace the whole unit, plus the furnace. He tried to sell me a new AC and furnaces and quoted me at over 13k.
When I refused to pay that much because I didn't feel it was right to pay for parts that didn't fix the unit, he went and uninstalled those parts.
I should have watched him, because not only did he take his parts back, but he also stole my disconnect, my relay, and my capacitor. He also cut the wires. He intentionally sabotaged my AC unit because I wasn't willing to pay an overpriced fee for a new unit and furnaces when the furnaces wasn't bad and I wasn't willing to pay for the parts when the unit wasn't fixed.
I called management and informed them what happened so they can be aware - that the tech not only tried to overcharge me, coerce me into buying a whole new HVAC system that isn't necessary, and that when I didn't agree, he intentionally sabotaged my unit from further work or repair.
Management did not care, stated he would never do anything like that. And they weren't willing to help in any way.
I had another company come out to reassess and he informed me he couldn't even perform a diagnosis because everything was gone. In 40 years he never seen anything like it. Ryan S stole my capacitor, my disconnect, my relay, and intentionally cut wires so the unit could never be further serviced or repaired.
Please stay away form this company! They don't care about families, they don't care about doing the right thing and helping people, all they care about it committing fraud and trying to get people to pay for things they don't need.

I did not want to write this but this goes beyond the pale. I needed ONE wall outlet changed from the standard 2 prong outlet to a GFCI outlet (3 prong). I'll give them credit, they came out quickly. The tech was very professional. The tech quoted me OVER $500. I agreed because I needed it done asap. Remember this was ONE outlet. The tech spent literally 10 minutes, start to finish. I tried more than once to call Calfo to discuss this abusive overcharge. I never received a call back. I priced GFCI outlets. They are well below $100 retail. I do not recommend Calfo.
