"This was by far the best experience I've had when it involves repairs. My heater had been broken for a year. Because I'm on a fixed income, I couldn't afford to replace it. Quotes from others all recommended replacement. HD Mechanical gave me an estimate for repair and it was fixed right away, an at a fair price. Brandon and Tim are the best and are professional and dedicated to getting the job done without trying to upsell to unnecessary replacement. It works fantastic. They also happened to fix my ac as well, with no cost to me. If you are a woman alone, hire this company. They're honest and fair, and provide great service"

"I had a 30+ year old air conditioner system that went out during the hottest time of the year. We contacted multiple HVAC contractors who didn't even want to diagnose the system, they just looked at it and said it needs replacement and gave us some outrageous pricing for it. Then we called Cool Air For You. They sent out Vadim who actually took his time with our unit and gave his honest recommendation. He let us know our compressor is out but our unit is completely rusted. He said he could possibly repair the compressor but there would be no guarantees how long the repairs would last. He also let us know that if the unit goes out again there would be no saving it and replacing would be our only option. He also said that if we do replace our system we would also have to replace the refrigerant lines as ours were currently made from plastic...this is something no other contractor told us. Since we were dying in our home due to how hot it was, we decided to go with the repair for now but had him give us a quote for replacement. A month later our unit was still working good but we decided to go ahead with replacement. We called back Cool Air For You on a Monday and spoke with Claudia she answered the phone right away and was able to get the install scheduled for that Friday. The installers, Victor and Andre came right at 8am, they laid out drop clothes on my floor so they wouldn't get my floors dirty...they worked very hard and stood at my place till the job was complete. They left around 6pm. Overall excellent experience with all aspects of this company, from the office, techs and installers. Honest and fair priced companies are hard to come by these days. Highly recommend to all friends and family. I never leave reviews but this company exceeded all my expectations!"

"They came out on time and did the inspection. It was determined that the thermostat was broken. We were shown options that he could install right then and there, and told how we could do it ourselves if we wanted a different thermostat. We chose a different one and installed it according to their directions. We have been toasty warm all winter."

I was in and out quick all fluids topped off, and potential problems brought to my attention, no sales pitch just good old fashioned honest people. We'll do business with them again. Highly Recommended

"My air conditioner broke on the hottest day of the year (113). I went on Angie's list and saw they were highly rated so I gave them a call. It was late in the day when I called, but they were able to come out the next day. The guy was able to get the AC working but said I probably needed a new system. This didn't come as a shock to me....it was getting old. I had gotten estimates before, so I had a dollar figure in my head for what a new system would cost. I called their office and scheduled an estimate. The young man who came out took his time and looked at everything. He explained what he was doing and why. When showing me my options, he didn't try to sell me the most expensive model, but the one that best suited my needs. It wound up being $3000 less then previous estimates I had been given. When it came to installation, their team arrived on time, put coverings down to protect my floors (HVAC is in the attic) and even brought a portable AC unit so I would be comfortable....it was about 110 that day. They thought it would probably take a day and a half, but they got it all done in one day. My AC is working great now. I didn't know how poorly my old unit was working until the new one was installed. I'll have to say that I have been impressed with this company from start to finish. Everyone from the lady who answers the phone, to the estimator, to the installers has been punctual, pleasant and informative. They send e-mails to confirm appointments, usually with a picture of who is coming. Also, the amount I paid for the first repair was deducted from the bill for installation. They are going to be my new go-to people for all heating and cooling from now on."

"Sent email through anigies list site, he called right away on a Sunday night - tried to help me fix my thermostat since it was only a year 1/2 old but we could not.  Did tell me he had a job in san diego that week.  since it was nothing major decided to wait since the reviews were good and he seemed honest.  finally was able to pick a good day, called letting me know he was on his way, showed up and first looked at my thermostat but it was broke, replaced with new one right away.  Explained how it worked also checked my filters and let me know where I could buy replacement ones at a good price.  Was quick, very friendly and professional.  Also does electrical work which I need so I will be calling in the future.

"Dave was very efficient and knowledgeable. He was able to supply my quote before he left. I look forward to working with Southland heating and air. Follow up: I made my decision and signed the contract. Best decision I could have made. They were thousands of dollars less for the exact same equipment than 3 other companies I got estimates from. When challenged none of the other companies could revise their estimate to even come close. Southland is a Mitsubishi diamond dealer so I got full Mitsubishi warranties plus 1 year from Southland of parts and service. The day the installers arrived, on time, it was raining. Jamie and Ricardo used the utmost care to protect my home. They covered the floors, moved and covered the furniture and made sure before they left that I fully understood how to use the remote and operate the equipment. I have attached a photo so you can see for yourself the way they carted for my home. The equipment works perfectly. I would hire this company again in a heart"
This is the outdoor unit that offers 17 SEER Hyper efficiency and super quiet operation of 54db's compared to 80 plus on older units
notice the low profile, this is about 14 inch wide instead of the traditional 36 wide.

"Very well. Technician, John Ruiz, showed up on time - as scheduled, was very polite, thorough, informative, and very professional. John pointed out some potential safety issues with our aging system and made some recommendations. My wife and I were very impressed with his explanations of his findings in our system as he showed us discrepancies and took several pictures of problem areas that would have been difficult to access. I also want to comment that the installation team, Adam Palazzola and Diego V. were nothing short of outstanding! It only took them 2 days of ripping out the old system and installing the new. Overall - we are very pleased with Home Comfort USA."

Install Boiler questions, answered by experts

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

Many utility companies and government programs offer rebates or incentives for the installation of high-efficiency propane boilers. These can offset upfront costs and improve your return on investment. Check with your local utility or installer for current offers. Incentives vary by state and provider, so exploring regional programs can help maximize your savings.

Professional HVAC installation requires licensed expertise in several areas, including electrical- and plumbing-related work. An HVAC team must know how to safely handle regulated refrigerant chemicals and the gas, oil, or propane used in furnaces and boilers. A proper HVAC installation protects your home from energy loss, fires, and even carbon monoxide leaks.

Costs range from $3,000 to $7,500, depending on system size and efficiency.
