All Star Mechanical, is a locally owned and operated, HVAC business. We have many years of experience behind us, thus we are confident that we can provide you with the best in HVAC service. We always respond quickly to your requests, always price reasonably, and the work performed is of the highest caliber. We use the best in materials as well. Thank you for selecting us and we welcome your questions.

"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!"

"The contractor scheduled me appointment two days out from the first time we spoke in order to come take a look at the job . He then showed up on time for the appointment. Told me he had something else to do that day but he will take a look into getting the part that I needed to be replaced and get back with me on a price. The next thing I know within the next couple of hours I got a call from him stating that the job was done. I was so thrilled. I highly recommend Smith's Heating. "

"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!"

"We called Holland Heating for a new furnace because ours went out the night before. We had previously gotten our air conditioner from them several years ago and had a great experience so we used them again. The salesman arrived promptly, was very professional and great to work with. He scheduled the new furnace to be installed the next day - which was a Saturday at no extra charge. Our job number is RA511081 and on 11-8-25 Kirk and Logan showed up and worked hard all day to install our new furnace. Kirk and Logan are very friendly to work with and they did a great professional job. They kept us up to date on the status as they worked. They are even great with the dog...I highly recommend Holland Heating and Logan and Kirk if you have any HVAC needs. Rachel Putnik"

Heating Oil questions, answered by experts

Yes, including optimizing settings and suggesting upgrades if needed.

Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.

Leaks, poor airflow, reduced efficiency, and loop blockages are common problems requiring service.

The most obvious downside is the high upfront cost of buying and installing one of these systems. Additionally, sometimes the system can take a longer time to heat than alternatives like a boiler. Also, if something goes wrong with the geothermal pump, repairs are often significantly more expensive than repairing traditional, above-ground heat pumps.

It’s a better use of energy (and your money) NOT to run an ERV system all the time. Most experts recommend that you cycle your ERV system on and off throughout the year. However, the recommended advice could change based on your climate, the number of people in your home, the size and style of your home, and your heating and cooling system. Contact a local pro for more specific advice.
