"Brandon came out on a Sunday and looked over the job site for details needed to present an estimate. Within a day I had the estimate with 3 options from low to high, all of which were reasonable the only difference being what equipment I wanted to install. Option #1 and #2 were lower end brands that were less expensive but since the difference in price betwee Option #1 and Option #3 was about $1400, I went to Option #3 which was their top tier brand, Carrier that clearly is an industry leader and trusted brand for longevity. I was installing a SINGLE ductless to cool a standard bedroom size room with a 18,000 BTU unit. The job took a total of about 5 hours since they were mounting the unit in a second floor bedroom and they needed to run the power/refrigerant lines two stories down to the compressor mounted on the wall. Everyone from Office Staff Jim to installers were absolutely wonderful to deal with. You can trust this company."

"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!"

"Nick returned calls promptly and arrived on time.  I asked him to text me when he was on his way, and he did.  He was nice to work with and explained our options along the way.   He initially came to our house on 4:30 on a Monday.  Then he came back Tuesday with the first necessary part.  He then ordered the new furnace and installed it on Sunday, which was perfect for us, since we didn't have to take time off from work.  The replacement went smoothly.

"The problem was resolved by cleaning a sensor for which they only charged me half hour labor. He also wrote me a letter when we filed with the licensing board. He suggested that I get a different type of connection from the gas. I wanted to give him some more business because he only charged me 50 bucks. So, I had him come out and do that. He showed up on time and didn?t jerk me around. He didn?t give me an inflated estimate and he did what he said he would do. I am pleased with him."

"Robert was absolutely exceptional in every way! I called Southland Heating and Air Conditioning to get an estimate for a new HVAC system (my system is about 15 years old) and Robert not only provided a detailed explanation of the best way to upgrade, but he also spotted a problem with the wiring on my Nest Thermostat. A true professional! Highly recommended all around!! I will definitely be a repeat customer!"

"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).

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

The primary differences between a heat pump and a boiler are their function and how they produce heat. A heat pump is a versatile system that provides both heating and cooling by moving ambient air and altering its temperature. In contrast, a boiler is solely a heating system, often working with a furnace or AC unit as part of a larger HVAC system. In terms of heat production, a heat pump generates heat more slowly and at a lower temperature, requiring a large convector for distribution. A boiler, however, produces a large amount of high-temperature heat that it emits through smaller radiators.
