"Our relationship with All Star Mechanical began with Chris coming out to diagnose my AC problem. He tested the system and diagnosed it as low on refrigerant likely do to a leak. We asked to get a quote on replacing the AC and the entire HVAC system. The furnace was a 25 year old Trane. The air filter was 1in thick and struggled to blow through a non-MERV filter, and I wanted cleaner air for the health of my family, especially since wildfires aren't going away anytime soon. We also wanted a whole house humidifier to assist the Vornado units we run 24/7 in the winter. Larry presented us with a variety of options for upgrading my HVAC system, not trying to sell me a system too large and expensive for our needs or climate, then explaining how everything works and how it works together to make our home efficient, safe, clean, and comfortable. The installation team was fantastic. They were scheduled for a 2 day installation and over performed installing the entire system in one day. Matthew and the 2 Nicks were great! Within 2 hours of installing the General Aire MAC high efficiency air cleaner we noticed the air felt and smelled cleaner, inspite of the poor air advisory warning for that day. Finally Chris buttoned the system up completly by running updated thermostat wiring and relocated my thermostat so the new system is compatible with my ADT Z-Wave ADC -T2000 monitored thermostat (my request)! Throughout the entire job, Larry stayed in touch, either by email, phone, or text to make sure everything met or exceeded our expectations. They are definitely Allstars!"

HHS specializes in the small odd tasks that float just above easy reach for the average busy customer: Let us assemble, hang, mount, repair, dispose, etc. We're reliable, convenient, and professional, and that means you don't have to sweat the small stuff.

"I hired Doty to repair a vent pipe. The work was completed. I have asked several times for a detailed invoice of the work performed and equipment that was rented to complete the work and have yet to receive that invoice or even a call to discuss the issue. I believe that they overcharged me for a piece of equipment that they not even use to complete the work. They also damaged my yard while attempting to use this equipment and never once have I been contacted by a manger as I requested. Their customer service is terrible and I would not recommend them to anyone!"

My main goal for every job is to do excellent work, with efficiency, at an affordable rate. I know having a stranger come to your home to help you can be uncomfortable, so I can reassure you that I am a friendly person and I will communicate exactly what am doing in as much detail as you want. I understand every person and need is very different, so I will listen to what you need, carefully, and work with you to find a solution.

"Really well. Very competent and knew how to fix our problems, taking over getting the materials needed and doing the repairs and replacements in 1 day."

Heating and Air Conditioning questions, answered by experts

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

Air conditioners and dehumidifiers are actually quite similar, though they perform different jobs. Dehumidifiers reduce moisture in the air, while air conditioners work to cool the home. A good central AC unit will naturally perform a certain level of dehumidification due to its design, but it will not be able to handle excessive levels of moisture.

Choosing a unit with higher BTUs can use more electricity if the BTUs are more than what’s necessary for your room size. However, choosing an AC with BTUs that match the size of your room or house, your unit will cool your space efficiently. On the flip side, choosing a system with not enough BTUs can cause the system to work harder to try to cool the space, leading to more electricity consumption and higher energy bills.

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

Set your house temperature between 55 and 85 degrees Fahrenheit while on vacation, depending on the season. If it’s winter, don’t go below 55 degrees. In the summer, the best AC temperature for energy savings is no higher than 85 degrees. You can save anywhere from 10% to 15% on your energy costs by adjusting the temperature while you’re away. If you have a smart thermostat, set up vacation modes for each season. On your way home, turn off vacation mode to allow the home to warm up or cool down before you arrive.
