"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. "

"Hired these guys to replace a hot water heater. While unpacking it in the driveway, a careless installer threw the packaging material and it landed on our car, denting the hood. They immediately acknowledged what they had done, called their office, spoke to someone named Dave, who reportedly advised us they would take care of the damage and would be in touch soon to make arrangements for repairs. That was the last time we heard from these clowns. "Dave", whoever he is, never called back, and failed to return numerous phone calls. In other words, he ghosted us. Bottom line on these morons - hell will freeze over long before I'll ever use them again. "

"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!"

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!"

Heating and Air Conditioning questions, answered by experts

A dual evaporator coil is a specific design that allows the AC system to cool different compartments at different levels. It’s usually seen in refrigerators and similar appliances, but not in whole-house air conditioning systems. Talk with your AC technician about the best uses for a dual evaporator coil.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

No, heat pump maintenance needs are very similar to air conditioners, including keeping outdoor units clean, changing filters regularly, and occasionally scheduling a refrigerant check to see if any has leaked out. Heat pumps typically switch automatically between heating and cooling, so you don’t need to worry about manually changing them every season. However, since they are always on call, they can develop wear and tear faster than an air conditioner.

Air conditioners can stop working in the middle of the night for many reasons. Your local power grid might shut down late at night. Power surges can also trip your breakers if too much power is being used in the area at the time. If your AC is connected to a digital thermostat, it gets naturally cooler at night, so the outdoor temperature might dip below the automated setting to turn the cooling system off.

Evaporator coils last between 10 and 15 years before they need to be replaced—as long as you stay up-to-date with routine maintenance. This is roughly the same life span as most AC units. So, if you have an older air conditioner and the evaporator coil goes out, it might be more cost-effective to replace the whole unit rather than just the coil.
