"We came home from an outing on a Sunday night and found our air conditioner not working. I found John Mullen on Angie's list and liked the reviews. I contacted John and he asked me about my schedule on Monday. He fit us in on Monday morning. I wasn't home but my wife was. She said that John was so nice that she assumed that he was a friend of mine. I told her that I never met him before. He fixed the air conditioner and I am relieved that it didn't cost us a ton and we avoided 85 degree heat with an air conditioner. I would use John again. He was dependable, came out with in 12 hours of being called, and my wife does not always comment on how nice someone is unless it is absolutely true. Thumbs up for John Mullen, I have just found a go to guy for everything!"

"We hired Bactronix to clean the HVAC ducts in our house. Technicians Masson and Shawn arrived on time, did their work unobstrusively and efficiently, and answered all my questions politely and fully. They sent over before and after pictures of the ductwork by e-mail afterwards. Their work has made a positive difference to the air quality in the house, and we appreciate their services."

"We were so happy to have Sullivan Super Service (Plumbing, Heating, Cooling) come today to repair our central air conditioning unit and to service our HVAC system. Sullivan's technician, Bob Anderson, was polite, professional and experienced. We greatly appreciated his knowledge and counsel. Our AC has been out for a few days in a current hot spell, and Sullivan was the only company that contacted us. They proved the old saying that in winning, half of the battle is just in showing up and being there. We were not Sullivan customers before, but we are now! Sullivan's service was SUPER!"

"Frank met with the estimate! I had no idea I would have the new furnace installation minutes after acceptance of his price. Nine hours dismantling old furnace and new one installed w/ central air. These guys are professional, kind and courteous! The price, quality and service exceeded my expectations. If you need a new furnace to replace the old one or new installation S &S Climate Systems are #1. I met with two other companies whose bid was larger, but S and S offered the same product saving me $1500-$2000, money I put toward upgrading my Electric panel and my sidewalk replacement!! And besides, I made new friends! Again, you owe it to yourselves to give your Heating and HVAC to S and S, because not only do they do good work, but their prices are within your budget range, there was no negotiating, in fact: I gave them a bonus. I was so pleased! Thank you S and S Climate Systems. These guys had everything stocked on their trucks, no time missed leaving the worksite to pickup items. They came prepared and delivered! Great job guys, you will go far! Keep doing what you do! Thank you for the Veterans discount! Semper Fidelis!"

Heating and Air Conditioning questions, answered by experts

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

Replacing both an AC and a furnace takes a full day on average, ranging from eight to 12 hours. The process involves removing the old units, installing the new ones, and ensuring all connections are properly made. If both systems are being replaced simultaneously, it can take longer than installing a furnace alone, so plan accordingly.

You should use a breathable, weather-resistant cover with ventilation. It can be a top cover or a full cover that has mesh to allow airflow. A full, non-breathable cover can cause moisture to build up, leading to rust, frozen parts, and corrosion. A full cover also attracts unwanted critters, such as mice, that can damage the wiring and your unit. If you need to protect your AC unit from falling icicles, choose a sturdy top cover or piece of wood that prevents icicles from damaging your unit.

Most HVAC companies recommend against setting your AC below 70 as it could freeze up the system and cause more problems. Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it’s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees.

You can adjust uneven airflow in your home by adjusting the dampers on the vents. However, if the temperature feels consistent throughout the home, don’t worry too much about uneven airflow. Generally speaking, larger rooms should receive more airflow than smaller rooms, especially if they only have one vent.
