"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!!"

"I have used Speer Air for several years for HVAC preventive maintenance at my home. We recently expanded and they installed a package unit to take care of the expansion space. The work was good and they have been back for adjustments as necessary."

"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.

"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

The cost to replace an AC unit averages around $5,900, with a typical range between $3,900 and $8,020. The final price depends on several factors, including the type and size of the air conditioner, its efficiency rating, your geographic region, and labor costs for installation. Smaller units like portable and window ACs are much less expensive, costing between $90 and $550, compared to central or ductless systems. If your current unit is less than 10 years old, repairing it may be more cost-effective than a full replacement.

In most cases, you should hire a professional to carry out services on your HVAC system, as the components are complicated, expensive, and potentially dangerous to work with. However, there are a few things you can do on your own to keep your HVAC system in good condition, including changing your filters every three months, keeping the area around your outdoor condenser clear of debris and plant growth, making sure your or intakes aren’t blocked, and keeping an eye out for increased energy bills, strange noises, and unusual odors related to your equipment.

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.

Yes, adding central air can increase your home value by as much as 10%. Generally speaking, prospective buyers prefer a central AC system over a ductless system or room-by-room AC units. That’s because central air conditioning blends into the home easier than individual room air conditioners and typically has less equipment to maintain.

Your AC might not cool after a power outage because of a tripped circuit breaker, blown fuse, or damage to the compressor or capacitor. If you notice your AC not working after a power outage, in most cases, the breaker has tripped or the system has built-in brownout and blackout protection. Reboot the AC by turning it off at the thermostat, resetting the circuit breaker, and waiting 30 minutes to turn the AC on again.
