"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!!"

"Speer Air just completed a complete overhaul of my existing HVAC including an upgrade of part of our system. The entire experience from initial sales visit to completion was great. Throughout the installation, the team was friendly, always available to answer a question, clean and respectful of my 3 young children (making sure nothing was left behind or any debris that could hurt them). System is operational and very satisfied. Highly recommend them."

"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

Yes, you can clean your air conditioner filter as a temporary fix for cleaning up dirt, but you’ll eventually need to replace it once the dust starts to accumulate. Use a vacuum with a hose attachment to clean your air filter at least once per year or more often if you have pets.

To find a reputable HVAC company, start by researching providers in your area. Look for companies with mostly positive online reviews and check the Better Business Bureau’s website for customer complaints. Next, verify their credentials. Rule out any companies that aren’t licensed, as this is a requirement in some states and municipalities, and confirm they are insured. Once you have a shortlist, contact each professional to ask key questions: How many years of experience do you have? Do you hold any third-party certifications? Do you have experience working on my specific type of HVAC system or brand? Can you provide references? What is your per-hour pricing? Do you offer maintenance contracts for ongoing savings? Do you provide a warranty for your work?

NATE (North American Technician Excellence) certification is not legally required for HVAC technicians in most areas, but hiring a professional with this certification is highly recommended. NATE-certified technicians demonstrated their expertise and proficiency in different types of HVAC systems, offering assurance of quality service. It's a voluntary certification, yet it indicates a commitment to professionalism and ongoing training. Choosing a NATE-certified technician often means you're working with someone who is up-to-date on industry standards and best practices, which can lead to better service, energy efficiency, and long-term cost savings.

No, you don’t need a ductless unit in every room. Ductless AC units don't work the way that window units do, where the air doesn't travel outside that room. The indoor air handlers all attach to the outdoor condenser. While the air doesn't travel the way that traditional ductwork would, the ductless AC units create zones so that one part of the home can be cooler than another. They can spread effectively enough that indoor units only need to be placed in main living areas.

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.
