"Fontana Brothers responded to my Carrier Air Conditioner issue, Andre was very patience and seemed to be very knowledgeable. A solution involved the ordering of parts and which was handled quickly. The parts resolved my issues. It great to discover in this present world that excellent customer service is still provided."

"I had a great experience with hometown heating and air. The gentleman who came out was professional and very knowledgeable. I appreciated how he was able to explain what was wrong with my unit and I was able to upgrade to a new duct system. This was done in a timely manner as well."

"I would suggest those of you looking for a great hot water heater repair company look at Ierna’s heating, cooling and plumbing at phone number 813-948-6355 or [*** Link removed ***] These guys do a GREAT JOB. Amy T (customer Service), Dan A (technician) and Steve W (plumbing manager) those I communicated with were very professional and polite. The technician arrived on time when promised. This company takes precautions to protect the public from Covid-19. I would recommend them to my family and friends or those looking for a GREAT COMPANY. I had an issue of no hot water coming from a tankless Titan water heater on July 23, 2021. I contact Ierna’s plumbing on Saturday July 24th and they dispatched their technician on Sunday July 25, 2021. I received an estimate on Monday July 26, 2021 as promised. I approved the estimate the same day; they ordered another tankless hot water heater and installed it on Friday July 30, 2021. So far, so good as I now have hot water again without any issues and based on what I see from the workmanship, it should remain that way. This company dispatched their technician to give a FREE ESTIMATE, which is GREAT. There are companies that charge $125.00 or more for an estimate; this in my opinion is ridiculous and as customers we should not be charged or pay this fee! Again, I HIGHLY RECOMMEND this company."

"West Coast Cold Air, Inc., is a great company. The owner Fernando, is highly reliable and a man of his word. After an exhaustive search to replace a dishonest and failing A/C Contractor who lied to us about his LIC and qualifications, we found West Coast Cold Air on the City of St. Petersburg, FL License Contractor List. After the fact we discovered West Coast Cold Air is registered with Angie List. I called Fernando and he promptly came out to the house we are renovating to assess our HVAC project requirements for an older two-story home that never had A/C. After interviewing nine other A/C contractors with no success due to their insurance coverage or internal business policy preventing them from touching equipment or completing another A/C contractors work. West Coast Cold Air did not hesitate to take on the job and assumed full ownership of the recently installed but abandoned equipment and uncompleted second floor project requirements. Fernando informed us to go to the City Permit Office to change the Contractor name on the recorded HVAC permit to his company's name and guided us through the arduous city of St. Petersburg permit process. The install was completed in four days to include: completing the missing Manual J Air inspection to complete the permit; finishing the install of the downstairs Mitsubishi ductless mini-split systems/outside condenser; sourcing and installing a new Central Air system for the upstairs: installing missing air return ducts for four rooms, and passing the Final HVAC Inspection. In addition, Fernando provided an outstanding insulation contractor recommendation for the attic. We are so happy and pleased with West Coast Cold Air and cannot say enough good things about Fernando's reasonable prices, integrity, and quality of workmanship. He is a real professional who earned our respect, I will always highly recommend him first--he is a rare professional you can count on!"

"After a cold night, turned up the thermostat to heat up the house and after about 1 hour the temperature didn't change.  Checked the breaker to the pump, turned it off, tried to turn it on again and the breaker kept tripping off.  I called Jim Morris on Sunday morning and he came by a few hours later and called me (as promised) when he was on his way.  This cost a bit more than his normal service charge (being a Sunday and it was an emergency service).  The heating system is working great now!
I've used this company the last 6-7 years for other repairs and maintenance check ups and am very happy with their pricing, professionalism and punctuality.

"My wife and I recently moved to St. Petersburg from Chicago, so when my wife called me at work to tell me that the air conditioning unit was not working I turned to Angies List for help finding an honest and professional HVAC company. Angies List did not let me down.

I called CSMP Heating and Air this morning at 9:40 AM because my wife noticed that the air conditioning unit was not blowing out cold air...it was also leaking fluid. I called CSMP and they were able to schedule a service call between 12-2PM, which I thought was pretty fast. Anthony, from CSMP, called 20 minutes later to say he could arrive early...much appreciated. He was at our home within an hour of our original phone call. Anthony diagnosed a small slow leak in the freon line that needed to be welded closed and then refilled with freon. He courteously and professionally welded and soldered the line and refilled with freon.

We could not be more pleased with the service of CSMP Heating and Air and the professional that serviced our air conditioning unit.

I think CSMP stands for "Customer Satisfaction is our Main Priority,....this is so very true with this company. I have found my new GoTo HVAC company in St. Pete's.

Thanks
