"Best Air Quality and Restoration did a spectacular job! I can't say enough about the employees. They did an outstanding job! They were punctual,polite and followed social distancing protocols.They assessed the home and cleaned the air ducts quickly and efficiently. I am very pleased with their service and highly recommended this company. I purchased a new home and had them come clean the ducts to improve the homes environment. They showed me before and after pictures and I noticed a difference right away"

"Our dryer vents from the center of the house to just under the second story eves. He did a great job of cleaning it from both ends, and adjusted the dryer hose to an optimal length and resealed it with tape. Also cleaned vents well. I am very particular about mechanics, handymen, and service people. Mack's is on the short list of people I will hire again. The serviceperson was polite and personable as well as very competent. And, he took pains not to track up the carpets. Mack's is a good choice. You'll be satisfied w the results."

"The 2 techs first showed up after my dryer had died and cleaned the vents (inside - out and also from outside-in) as much as they could but said they needed me to have an operating dryer so that they could make sure everything was pushed out the side vent and airflow was good. They were very knowledgeable and honest which I appreciate when hiring any company without a first hand recommendation from my own friends/relatives first. They rescheduled a follow up appointment after my new dryer was delivered and were here the same morning and finished the cleaning and confirmed that everything was cleaned and working as it should now. I'll definitely hire them again next year and try to keep up an annual cleaning so it doesn't get so clogged next time. Highly recommended."
"We are very pleased with the job Dave did for us today. He was prompt and very courteous and did a professional job cleaning our carpets. Thank you for keeping the planned schedule as promised. We will recommend your company to our family and friends. Stan"

Air Conditioning questions, answered by experts

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.

Yes, mini-split systems are generally less expensive to run than central air conditioners and are significantly more energy-efficient. Because mini-splits do not rely on ductwork, they avoid the energy loss associated with ducted systems, allowing cooled or heated air to reach its destination more efficiently. Additionally, they offer zoned control, meaning you can run units in individual rooms and turn them off in unoccupied areas. This capability can lead to energy savings of about 30% compared to a central air system, resulting in a lower monthly energy bill.

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.

Signs that your air conditioner capacitor is bad or failing include a range of symptoms. The AC unit may not turn on at all, or it might struggle to start before shutting down randomly or in the middle of a cooling cycle. You might hear a humming or banging noise when it attempts to start, or the compressor might hum without the unit actually running. Other indicators include a smell or smoke coming from the unit, the blower circulating room-temperature air instead of cold air, and an unexpected increase in your energy bills.
