"Ken came out originally to do some duct cleaning but noticed that a lot of our supply and returns weren’t sealed properly with mastic (he showed us the areas that needed work). He came back out and sealed all the ducts, installed an air purifier and cleaned and sanitized all the ductwork. He was polite, knowledgeable, professional and hard working. Definitely recommend his services."

"Fontana Brothers installed my new Bosch HVAC system, and I couldn’t be happier with the experience. Freddie and Shaquille arrived exactly on time, worked efficiently, and left the work area cleaner than it was before they began. Their attention to detail and professionalism were outstanding. As a Realtor for more than 30 years, I’ve dealt with many HVAC companies, and Fontana Brothers continues to be one of the very best. They consistently deliver excellent service to both me and my clients, and their pricing remains highly competitive. I trust them completely with my referrals. Special thanks to Dan Fontana, who heads the service department — always organized, responsive, and helpful — as well as the entire office staff, who are consistently friendly and a pleasure to work with. I will absolutely continue to recommend Fontana Brothers to others seeking HVAC installation, repair, or replacement."

"Great installation Team. Professional, meticulous and very personable. They came on time and worked all day to replace my 18 year old system with a top of the line highly efficient system. They cleaned up everything and left it spotless. They even vacuumed the small amount of dust they made installing new thermostat in house. I am nosy with these kind of things. They answered every question politely and thoroughly when I asked them. During the installation, every time I went to see how things were going, they were hard at work constantly. I HIGHLY recommend Ierna."

"It turned out great. They were very patient, in terms of working with me and helping me understand my options and what was out there. They were very professional in their dealings; the installation went smoothly and overall the job went well. They actually improved upon the plumbing and water coming in, so it was more user-friendly for me. They were very nice folks to work with. I would recommend them to anyone!"

"A far cry from my previous experiences with ac guys, Air 4 U and Steve Tuure was a fantastic experience for us. He gave us a more than fair quote considering what he was selling us and the work he was including in it. He performed it in half the time he said it could take. He and his employee were super friendly and incredibly hard working. I would definitely recommend Steve to anyone who need A/C repairs or replacement.
I was told he was the most honest AC guy around and I found that to be true. While some of the other estimates I got turned out to not be as accurate as they originally looked but even if they were Steve's prices and bang for buck would have beaten them. I feel very confident the installation was done by a knowledgeable and experienced tech and that he will be super responsive if I ever have a problem.
The job seemed to be a bit more than we originally thought considering mold was found and ducts had to be replaced, clogging was found in the pipeline, and a number of other not-so-fun additional problems. But Air 4 U did all the tasks and didn't ask for a penny extra to complete them.
Steve took the time to talk to me about different things we could do if we wanted with an air filter box he had installed and even told me how to get the best filter that didn't have to be replaced.
My husband and I laughed when we realized we no longer know when the ac comes on and off because the loud clanking is gone, but I honestly don't think I have ever heard such a quiet ac outdoor unit before. We are uber impressed. If you want someone you can trust - go with Steve.

"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!"

"Plumber was prompt and arrived when scheduled.  He unclogged my bathroom pool toilet.  He then gave me a price for the installation of a laundry tub.  He came the next day and neatly broke through the garage wall to get to the pipes to be able to install  the laundry tub.  This precise cutting of the sheetrock made it possible for my husband to reinstall it  without any problem.  I would recommend this company and will use them again."

Install Boiler FAQs, answered by experts

Most propane boilers last 15 to 20 years with regular maintenance and proper care. The lifespan depends on the quality of the unit, proper installation, and the level of maintenance. Investing in annual service can maximize longevity and efficiency. Routine inspections and timely repairs prevent early breakdown, ensuring your boiler heats your home for years to come.

Warmed or cooled air can escape your home through drafty windows and doors. If you notice any gaps, be sure to caulk and seal them. You can also hire a local pro for an energy audit to get a list of energy-saving recommendations. 

Finally, check your insulation. It can settle in over time and become less effective. The Environmental Protection Agency (EPA) estimates that you can save an average of 15% on heating and cooling costs (or 11% of total energy costs) by sealing leaks and making sure attics, crawl spaces, and basements have a nice layer of insulation.

The right type of HVAC system will depend on several factors, including your climate, budget, preferences, and existing HVAC setup. For example, if you live in an area that experiences extreme weather, then a split system would likely be the best option. Or, if budget is a concern, consider installing a ductless system in just one room.

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.

Steam boilers require flushing at least every six to 12 months to keep them operating effectively for as long as possible. Depending on your water quality and frequency of use, you might need to do this more frequently. The flushing process helps to remove problematic buildup of sediments. While a boiler contractor near you can perform a thorough annual flush, learning how to drain the system yourself means you can do this monthly if you experience speedy mineral accumulation because of hard water.
