"I couldn?t be happier with the experience. Graham Solution handled the entire installation from start to finish, and the quality of the work was outstanding. He was professional, knowledgeable, punctual, and paid close attention to every detail. The installation was completed efficiently, everything was left clean when the job was finished, and the system works perfectly. It?s hard to find someone who takes this much pride in their work, and it definitely shows. I highly recommend him to anyone looking for reliable, high-quality HVAC installation. Excellent workmanship and great customer service from start to finish!"

"Great! He provided additional information, suggesting I install a UV Light Air Purifier to my HVAC system. Which would help eliminate the possibility of mold growing in my vents."

"I would wholeheartedly recommend Joe Norwood to anyone. His HVAC winter service was more expensive than a lot of other companies advertise ($170 with a $70 trip fee versus a lot of places advertising a $80 summer/winter inspection). However, there were no hidden costs (I'm sure the $80 balloons to almost $200 really quickly), and during the 2.5 hours Joe was here he took the time to explain more about my HVAC system and various ways to run my heat pump more efficiently in the winter. Overall Joe was punctual, honest, and worth the money. The old adage rings true - you get what you pay for, and Joe was worth every penny."

"Overall the job went well. We needed a new HVAC system which included a new gas furnace and new AC unit. The sales rep was punctual and responsive to questions. The installation team was punctual as well. The B ratings in some categories is due mostly to communication issues to occurred. Apparently some of the things the sales rep agreed to with us were not communicated to the installation team, so when they invited me down to inspect the work three minor items had not been completed. After I brought it up, the installation team offered to do the work in order to ensure I was satisfied, but they also brought up some valid points on why having that work done may not be what I actually wanted. Therefore I was confused. After calling the company main office, the owner owner called me back within 30 minutes to talk through options to ensure I was satisfied with the job. We agreed that two minor items didn't need to be changed, and he offered an upgrade on the third item, at no additional cost to achieve the functionality that was missing from the third minor item. That component was installed the next day. Lastly, the installation team missed some small trash items when they cleaned up the exterior part of the job."

Heating and Air Conditioning FAQs, answered by experts

The higher the BTU rating an air conditioner has, the more effective it can be at cooling your space. It will cool off your room faster in the short term. However, over the long term, if the unit has too many BTUs for the space, it can wear down the unit faster and shorten its life span.

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.

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. 

Indications of an HVAC problem include inconsistent heating or cooling throughout your home, unpredictable temperature changes, or inadequate air flow from vents. Abnormal sounds such as grinding, banging, or hissing, and unpleasant smells like mustiness or burning are also potential warning signs. A rise in energy costs without an increase in usage may also imply decreased efficiency. An HVAC system that frequently cycles on and off or cannot maintain a stable temperature is malfunctioning.

Yes, HVAC zoning systems offer energy savings by allowing precise temperature control in different zones in your home. Rather than conditioning the whole house uniformly, these systems direct airflow where needed, preventing energy waste. Tailoring comfort to specific areas reduces energy consumption and lowers utility costs, making HVAC zoning an energy-efficient choice.
