"We needed the 32 year-old ductwork replaced in our second story due to heavy infiltration of dust, pollen and bits of fiberglass insulation from the unfinished attic portion from deteriorated ducts. Given our pretty severe allergies to tree and grass pollen, the second story rooms were mostly unusable and even the first floor a problem, not as bad but still unpleasant. Even our cat was suffering. Drew, the sales manager, gave the whole system a very thorough review. He measured our rooms and discovered the system was oversized for the square footage, which not only put strain on the blowers but made the sound at the registers so loud it was difficult to speak on the phone in my office. He recommended an additional register in the hallway between the rooms. Glad he did. The thermostat is located in the hallway which also looks out over a large room with a cathedral ceiling. The new outlet has helped normalize the temperature and the AC/Heat run much less now and give more even temperatures. He also recommended a full house filter on the blower and an in-duct LED purification device that treats mold, dander, pollen and dust. Again, glad he did. They have made a big difference very fast, especially in pretty dramatically reducing dust and improving our respiratory systems. We had the same devices installed on our downstairs unit. We also had a detached first floor duct. In an above and beyond move, Drew went into the crawl space to check it out and temporarily repaired the duct until Maynor could replace it. The installation team, Jeff and Seth, were the superheroes of the project. There were two ducts so tight under the roof they looked as if they couldn't be replaced without tearing out part of the ceiling. One of those ducts had been shredded all the way through by an animal. It came out right over my desk and had been raining pollen, etc. down on me for some time. Seth managed to squeeze into the tight spots and replace the ducts all the way to the boxes. Both guys were very professional and personable and did a great job as unobtrusively as possible in a single day. Also very proud of the company and obviously happy to work there. Maynor sounds like a very customer and employee focused company."

"Lahcen is an excellent HVAC technician! He quickly diagnosed the issue with my AC unit and clearly explained what was causing an error in my AC unit and while he was diagnosing the main issue, he checked my filter he found out it was upside down. Professional, knowledgeable, and honest. I highly recommend him to anyone needing HVAC service."

Air Conditioning questions, answered by experts

Swamp coolers cost approximately 50 percent less to install than central air conditioners and cost less to run. Operation costs depend on the size of the unit and home, your climate, utility rates in your area, and the system’s efficiency. Swamp coolers use 15 to 35 percent less power than air conditioners.

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.

No, you don’t need a ductless unit in every room. Ductless AC units don't work the way that window units do, where the air doesn't travel outside that room. The indoor air handlers all attach to the outdoor condenser. While the air doesn't travel the way that traditional ductwork would, the ductless AC units create zones so that one part of the home can be cooler than another. They can spread effectively enough that indoor units only need to be placed in main living areas.

HVAC companies may charge an hourly rate or a flat fee. Hourly rates typically range from $100 to $250 per hour, with an average around $175. Some contractors charge a flat fee for specific services, such as an inspection, which can cost between $150 and $500. The total cost of an HVAC service is influenced by several factors, including: the urgency of the service (emergency repairs after hours or on holidays cost more), the time of year, the type, size, and brand of your HVAC system, the specific repair needed, and whether you have a service contract.
