"I spoke with Jorge about a gas leak coming from my furnace. He was so honest with me and recommended that I call the utility company to come fix it instead. PSEG came within an hour and fixed it for free. I had another company come out yesterday and they told me that I needed to change the gas value, so Jorge was able to save me hundreds of dollars. If I ever have any future HVAC issues, I will definitely trust Challenger to do the right thing and not scam me. Thank you so much!!"

"My wife and I moved into our home about two years ago and inherited a very old hot water heater (12+ years old) and boiler (25+ years old).  They were working fine, but they were on their last legs and could go at any time.  More importantly, 2 of the 3 upstairs bedrooms were always cold, little heat reached those rooms through the baseboard radiators, and we wanted to see what could be done to get it fixed.  This was very important to us since one of those rooms was going to be used as a nursery the following month.
I spoke to Dave on the phone who set up an appointment for the next day to investigate.  He assessed the water heater and boiler, letting me know that they were currently working fine, explained how it worked, and that the boiler was missing a safety feature that is now required in newly installed boilers (I think it was something like an expansion tank?).  He explained it very well, I could tell he knew what he was talking about.  To solve the cold bedrooms riddle, Dave walked around the basement, looking at the exposed pipes and where they were headed.  Then he went to the rooms on the first floor, noting the locations of the radiators.  Finally he went to the 2nd floor to see where the rooms were and the radiator locations.  He found that the rooms were connected just fine, but that they were on the end of a long loop of rooms being heated.  The 2 bedrooms were located on the same zone as the entire first floor, and as a result, were not being heated effectively.  In addition, the thermostat was on the first floor, meaning once the desired temperature was reached on the first floor, the system shut down, leaving the 2nd floor in the cold.  To fix, he recommended adding a third zone by reconnecting the 2nd floor pipes in the basement directly to the boiler and connecting a new 2nd floor thermostat to the boiler so that it would continue working until the 2nd floor rooms were warm.
It should be pointed out that the original intent of my service call was not to get a new boiler, but to fix the heating problem on my 2nd floor.  The 3rd zone solution complicated things with my older boiler, which would have had to be retrofitted with a bigger opening to accommodate the 3 zones.  Dave advised that rather than spending money on those enhancements, which would go to waste if and when my boiler dies, that I may have wanted to consider getting a new boiler.
My wife and I agreed to the work and we scheduled an appointment a few weeks later to get the work completed.  On Day 1, they replaced the water heater and did some work on the 2nd floor piping in the basement.  On Day 2, they replaced the boiler and connected all 3 zones, including the new 3rd zone.  The crew was excellent, putting down drop cloths around the house where they were walking around to drain the radiators and cleaning up behind them.  When the work was completed, Dave walked me around and showed me what they did and gave me a tutorial of how the new thermostat worked.  Everything worked perfectly and the upstairs bedrooms are now nice and warm!
Dave came back a few days later and dropped off the invoice, warranty, and completed rebate details (all I had to do was fill in my address and mail it out).  He also asked how things were going and answered some questions for me, including how I could adjust temperatures in the room using the radiators.
All in all, I think I got my money's worth and would recommend Dawson to my friends and family for any heating work.

"I would highly recommend No. 1 cleaners. I just purchased my home and my air ducts were never cleaned by the previous owners. Vincent arrived on time, explained everything in full detail and got to work. Vincent did such a great job and spent extra time due to the extent of the neglected air ducts. He also cleaned the furnace motor that was never cleaned and full of dust from home renovations. He also cleaned my dryer vent, which was not properly installed. He reinstalled the vent and made sure everything was properly secured and cleaned. I have already recommended them to family and friends!"

"We searched for a long time for a company to replace a current central A/C which was not particularly old, but the handler up in the attic was nearing the end of life so we had to replace the whole system. Speer seemed most knowledgeable, offered a product we were comfortable with (Amana) and were also professional and prompt. Of note we had a troublesome smart thermostat which required that they return multiple times to address - they did not consider the job done until this was fully operational. Overall we were very pleased, but the summer will tell!"

"We hired them to clean our HVAC ducts as we had just bought this house. We are glad we did as before pics showed a horrible situation. They were reasonably priced and they were quick to respond to our needs. Work was completed within 48 hours as requested to meet our schedule. Highly recommend them"

Heating and Air Conditioning questions, answered by experts

There are a few reasons your AC is running but not cooling your room. Thermostat issues and dust and debris, which can clog your system, are common problems. It could also be a broken component, such as a compressor, blower fan, or evaporator coils. You’ll need to call a pro to diagnose the issue.

The compressor is the heart of your AC system and is one of the most important parts required to keep it functioning properly. If your AC unit is making a popping, banging, clanging, clicking, or screeching sound, it could point to a problem with the compressor. If the unit is physically vibrating, that can also be an indication that your AC compressor is going bad.

Swamp coolers cost approximately 50 percent less to install than central air conditioners and cost less to run. Operation costs depend on the size of the unit and home, your climate, utility rates in your area, and the system’s efficiency. Swamp coolers use 15 to 35 percent less power than air conditioners.

You should know the main components of an air conditioner: the condenser coils, evaporator coils, drip pan, AC filter, ducts, and refrigerant. Each part plays a key role in the performance and safety of your AC system. When tracking the source of AC issues or odors, it helps to know where to look. Your outdoor unit houses your condenser coils, fan, and compressor. Your indoor unit houses your evaporator coils, drain lines, and filter, and it connects to your ductwork. 

Air conditioners can stop working in the middle of the night for many reasons. Your local power grid might shut down late at night. Power surges can also trip your breakers if too much power is being used in the area at the time. If your AC is connected to a digital thermostat, it gets naturally cooler at night, so the outdoor temperature might dip below the automated setting to turn the cooling system off.
