Chev was extremely professional and polite. He explained in detail the problems and recommendations. He also cleaned up after the jobs was completed. We will definitely use your company’s services again because of Chev! Thanks for the support 👍🏾
Had a great experience with this company. Hot water tank started leaking. Called on a Sunday to leave a message for a call back and put on a schedule. The call was answered and Benito came out within 2 hours. Had an assessment and a quote, as well as scheduled the next day for replacement. Benito arrived the next day on time, after a courtesy call and quickly replaced the water heater. Zero issues with the service and quality of work. Only concern, is that you pay for the quote, unless you sign up to be a VIP. Had I not known for sure I was going to use Calfo, I probably would not have agreed to getting a quote. Definitely recommend. Price was on the higher end of expectations, but I feel I got what we paid for.

I wish I could give more than 5 stars. Tim came out Monday after Snowstorm Fern hit with a foot of snow. We had another furnace company come out on Saturday before the storm hit with 2 separate Techs, neither of them could fix it and kept talking down to me saying it was my fault. They removed my air filter (did not put a new one in and just left it empty) and installed 2 oil filters saying they kept getting clogged within an hour of each other which makes no sense... 1 filter is good for an entire season, not only 1 hour but to them I was the idiot and they told me just as much. Once the second tech said it was fixed it still sounded very rough to me so I asked if it breaks again what do I do, is it something I can fix myself, or can I call them for help again. The second Tech told me to not call them, there was nothing they could do...my furnace broke again few hours later. I needed a second opinion asap and decided to reach out to Calfo as we had no heat at all for 2 days and I was out of my mind with stress. Tim showed up and asked if they replaced a nozzle with the oil filter because its a given you do both. I said no the last company didn't but instead took my air filter and replaced 2 oil filters which he was even shocked they replaced an oil filter with a new oil filter that was only installed an hour before. Within 20min we were permanently fixed and running smooth. He was very friendly and super knowledgeable about our system and even offered to drop off air filters for us since the last company took them but did not replace them yet I still got charged. We even signed up for the maintenance program so he will be our tech for a lifetime because I no longer trust anyone besides Calfo & Tim to treat me right and get the job done efficiently.
Called in an emergency as my service panel was arcing. Mason came with in an hour. Figured out my one leg was dead. Go it so I had heat for the night. Agreed on a price and set up to get the panel and full service install the next day. Day two. Gary was first to show up explained everything that was gona be done that day answered all my questions then got started. Patrick showed up shortly after and started the outside as Gary did the inside. They had everything as far as they could go and were waiting on Mo (third tech) to arrive. Once he did they continued working completed the job in about 6.5 hours. Including the time they were waiting. Very impressed with Gary and Patrick. Project turned out good got my power all back on and cleaned everything up.
Everyone involved with replacing our furnace was kind & helpful, especially Becca & Conner. It was below zero and they came on an emergency call and got everything done in one day. Great company, great employees, great experience. Thank you Calfo. Highly recommend!?
