"I had used Ed before with my other house. I recently hired him to clean the dryer duct at my other house. When he moved the dryer, he saw that there was a lot of lint in the body of the dryer (a fire hazard). Because he could access it, he cleaned it all out as well as the duct. The air flow is perfect. I recommend Ed and Air Duct Professionals highly. I have used his company two times, and I am extremely satisfied."

"Very pleased with professionalism, quality and price. James, Keith and Quincy completed Al elements of heat and air new installation on time and to specifications. They communicated with us well about every step of the process. It was nice to have someone come into the home and just complete the work without any issues. Owner Michael was very clear without sales hype. Strong background and understanding of home needs."

"I would highly recommend this company to anyone. The rep I had only charged me for the ac sealant and the two pounds of freon he used. He was very friendly informative and very fair. It's too bad you can't find service like this all the time."

"We recently had Same Day Heating and Air Conditioning come to our house to inspect our furnaces before turning the furnaces on during the cooler winter months and they discovered that both units had gas leaks. The system is 20 years old so it wasnâ t a complete surprise although we had hoped to put off replacing them for about 1-2 years. The technician/ inspector was knowledgeable, thorough and professional in showing us pictures of the worn, damaged furnaces (2). He explained the options for repairs and replacement as well as pricing considerations. In the end we decided to have them install 2 new furnaces and 2 new heat pumps to replace our old AC units. The installation was scheduled and completed within a short time frame and done with as little disruption to our home and family as possible. Efficient and neat in their work, I can happily recommend Same Day Heating and AC. I am very reassured knowing that my furnaces and heat pumps can effectively and safely heat and cool our home for our family. Peace of mind is priceless when it comes to protecting your family."

"Did a great job...it was a very long day from start to finish however. They did a great job of keeping everything as clean as they could since our attic access was in the master closet! Yikes! Really made a difference and our house stayed much cooler with the fan and new insulation!"

"Arturo with Veterans HVAC completed the electrical work for my pump. His solution to complete the installation was elegant and simple compared to the bids I received from others. Veterans was not the least expensive but it was well worth the extra cost to get the job done correctly. I would not hesitate to use them for other projects."

Air Conditioning FAQs, answered by experts

Yes, you can run an attic fan with the AC on. In fact, you don’t have a choice with a passive attic fan. Plus, when an attic fan draws out hot air from the attic, it helps regulate the temperature of your whole home, so your AC doesn't have to work as hard.

A blockage in the ductwork may prevent air from flowing through the vent. If some rooms in your home are very hot or cold and another isn't, that can be a sign that a vent is blocked. Another sign of a blockage is a buildup of dirt or dust around the vent. In either case, a duct installer or cleaning service can investigate the issue for you and recommend a course of action.

On a summer day, expect your AC to run between 12 and 16 hours. However, this time frame depends on just how hot it is outside and the comfortable temperature you’re hoping to maintain indoors. Assuming the size of your AC is appropriate for the space you’re trying to cool, it shouldn’t be a problem for it to work this many hours.

Mold in your air conditioner isn't a good thing, as it can be harmful to your health. If the mold travels through the ductwork or is blown out of the A/C, you and your family can inhale mold spores and develop respiratory illnesses and other problems. Preventing mold from growing in the air conditioner will help protect your health.

To make the most out of your AC, consider implementing the following best practices: 

  • Choose the right size AC for your home to ensure your unit runs as efficiently as possible.

  • Choose a window with shade, as direct sunlight can cause your AC unit to overheat. 

  • Clean or replace the filter at least every two months. 

  • Inspect the AC’s fan and straighten it if necessary. 

  • Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. 

  • Turn off (or adjust the temperature) when you leave the house.
