"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!"

"I used Regal Duct Cleaning today. Our home is 60+ years old. We have only lived in it for 20 months and there was more dust, dirt and webs than I had ever imagined. Julius and his crew arrived at the scheduled time. He was extremely professional. We went from room to room looking at every every vent, cold air return. His crew worked for five hours, cleaning the ducks, dryer vent and installed a UV light. I highly recommend Regal Duct Cleaning . I will definitely use them again! To see the before and after pictures was a real eye opener. Great Job!"

"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."

"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."

"Their technician Jason Lord was a true professional. Not only was he proficient and highly skilled at his craft but was a true professional with his customer service skills. It is very rare to have both qualities of mechanical skills and customer service expertise. I would recommend this company to anyone that needs HVAC repair."

Heating and Air Conditioning FAQs, answered by experts

Yes. It's not just AC filters that get dirty. Ducts can accumulate dust and dirt quickly. Insects and animals can also get into duct systems, creating many problems. Dirt build-up and unwanted guests can constrict the airflow and cause rooms not to cool evenly. You might also see higher energy bills because they're not working as efficiently.

You will only need to refill your AC with refrigerant if it has a leak. Otherwise, a modern, well-maintained AC will most likely never need a recharge. You may notice a leak in an older system if your bills are higher, you hear a hissing sound, or if the air is blowing out hot.

Yes. In fact, not only are AC tuneups worth it, but they’re actually necessary to keep your air conditioner in good condition, improve its efficiency, and potentially prevent major damage. Experts recommend getting a tuneup at least once per year. In most cases, you’ll want to schedule it during the spring so that you can address any issues before the hottest months of the year.

Some AC filters, known as reusable filters, can be cleaned and reinserted. Most AC filters, however, are disposable and cannot be cleaned. 

There are several tell-tale signs that your AC coils need cleaning, including:

  • You’re getting higher electricity bills.

  • Your home doesn’t feel as cool as it usually does.

  • Your AC unit is running longer than usual to cool your home.

  • Your home is more humid than usual.

  • The coil is covered in frost while running.
