"Michael installed a new AC and Gas Heater in my home this summer and it's working great. He is very professional, knows his stuff, works hard and clearly takes pride in his work. Also, hes a good guy. I lost a baby chicken under a staircase and he was willing to take it apart to retrieve the chick. Luckily the chick popped out and Michael grabbed the little bird. I would highly recommend Deans Heating and Air Conditioning. Update - 11/24. Michael promised a visit this fall to check on the heater. As promised, he showed up and did a check on the heating and all was working great."

"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"

"Turned on the AC this morning to find out was blowing hot air, called up a few different companies who wanted minimum 100 bucks to come out blah blah blah, called up Markool and got connected with a technician. The technician helped me troubleshoot the issue, and have me a quick fix that will last until they make it out tomorrow to do the permanent fix. I'll be using them for all my AC needs in the future!"

"Brandon Brock arrived at my home this evening. He is very relatable with a keen sense of professionalism for the services he provide. I now understand how to properly clean my air filter and operate my nest thermostat. I still operate sort of old school but he encouraged me to utilized the nest app to help manage the temperature of my home. Most people use jargons, or acronym when explaining techniques, but Brandon was very patient with me and did not mind explaining anything more than once. It was a pleasure to meet him and started my weekend off in a good way."

"I just had my semi-annual maintenance of my heating/AC system and dehumidifier done by DwIght. He did an excellent job and answered all my questions. The system is one year old and everything works well. The Blue Dot installers did a fine job last year."

"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

A new HVAC system combines components to control indoor temperature and air quality. Features include a furnace or heat pump and an air conditioner or evaporator coil, depending on the climate requirements. It also involves a network of ductwork for air distribution, a thermostat for temperature regulation, and electrical connections. Air purifiers or humidifiers can be integrated to improve indoor air quality.

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location.

A few drips here and there should not be cause for concern, but if your unit is leaking a large amount of water, then it’s advised that you stop using it until the problem is identified and a solution is determined. The more you use it during a leak, the more issues it will cause.

When faced with HVAC issues, it's best to begin by ensuring the thermostat settings are correct for either heating or cooling. If the system isn't responding, check the thermostat for proper function and power supply. It's also important to examine air filters, as clogged ones can decrease performance. Confirm the power supply to the system by checking the circuit breakers and fuses. If these basic steps fail to resolve the issue, contact an HVAC professional for a more detailed diagnosis and repair.

The compressor is the heart of your AC system and is one of the most important parts required to keep it functioning properly. If your AC unit is making a popping, banging, clanging, clicking, or screeching sound, it could point to a problem with the compressor. If the unit is physically vibrating, that can also be an indication that your AC compressor is going bad.
