"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!"

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

Split systems are the most common type of HVAC system. Split systems have two main units: an indoor one and an outdoor one. These units work together to pull in air, heat or cool it, and distribute it throughout your home. Other popular types of HVAC systems include hybrid systems and packaged heating and air systems.

There are a few reasons your AC is running but not cooling your room. Thermostat issues and dust and debris, which can clog your system, are common problems. It could also be a broken component, such as a compressor, blower fan, or evaporator coils. You’ll need to call a pro to diagnose the issue.

If your AC condenser is nearing the end of its life, it might leak fluid or make loud or unusual sounds (like grinding or hissing). You might also notice that it isn’t heating your home as evenly or effectively as it once did. Also, an aging condenser will have to work harder to cool your home, which may force it to use more power and drive up your utility bills.

Here’s how AC professionals will clean your AC coils:

  1. Unplug the AC unit or turn off the breaker to the unit in your circuit breaker box.

  2. Remove the faceplate.

  3. Spray a vacuum hose attachment or compressed air can to remove debris, dust, dirt, and grime.

  4. Use a soft-bristled fin comb to remove stubborn caked-on debris.

  5. Use the vacuum hose to suck up any extra debris.

  6. Take a coil-safe cleaning solution and spray it onto the coils. Try to choose a no-rinse solution.

  7. Let the solution sit for at least 15 minutes.

  8. Gently wipe away loosened grime and debris with a microfiber cloth.

  9. Reattach the faceplate, plug in your AC system, or turn the breaker back on.

Freon will go in the refrigerant lines near the back of your AC unit. Look for small ports with caps on a thin copper line—the Freon goes into those ports. You are best off hiring a licensed HVAC professional who can complete the job safely and correctly.
