If you are new to Doty Mechanical again we say welcome, if you are a current customer we thank you for your continued patronage.

"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

When the capacitor fails, the AC unit can’t operate at all. The most common sign is the thermostat forcing the blower to turn on, but it only circulates room-temperature air. The AC unit also won’t make any noise or indication that it’s on. Sometimes, the compressor might hum as it attempts to work, but without any results.

Before a full shutdown, a faulty capacitor can cause your AC to struggle while turning on. The unit might also shut down in the middle of a cooling cycle.

Yes, there are ventless portable air conditioners that don’t have exhaust hoses and don’t require venting. Instead, they have a water reservoir and cooling pad, which add moisture to the air to make it feel colder. Ventless portable AC units work best in dry climates since humid areas already have a lot of moisture in the air and can’t absorb much more.

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.

There are plenty of different not-so-great sounds to hear from your air conditioning unit, like squealing, grinding, water running, excessive gurgling, banging, and clanking. Each of these sounds can indicate a different malfunction with your unit, so it’s important to have a professional assess the problem before it gets worse.

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.
