"I called to get a third estimate on replacing my residential boiler. I was looking at replacing it because other contractors had advised that the cost of repairs was too high; repairing a 20 ye old boiler didn’t make economic sense. Gilles sent Justin over the next day, so very quick service. Justin gave me a ballpark price to replace it, which was more in line with what I thought was fair. He also gave me a very fair price to repair it — about a third of what the other contractors quoted. A good chunk money, but a much better option right now. Comparing what the three contractors told me, I’m confident that Justin had it all coveted. He then allowed me to video him, explaining what he did and what I should expect and look out for. He also sold me on their annual maintenance plan, which is a bargain because it includes evaporative cooler startup and shut down."

"Highly recommended and I will be calling next time I need help. My heater wasn't heating so I called around. Dylan was able to come straight over, less than 2 hours after I called the house was warm. Luckily it was a simple fix, no parts needed (a spider had built it's web in there), so the whole repair was covered under the $89 service fee. Dylan was respectful of me and of my home. AND he told me they work on swamp coolers, which is sort of hard to find these days."

"Initially I requested an estimate for a plumbing project already in progress with some challenges. Keith responded immediately to get details and schedule to come out to look at what was needed. He proposed a solution that eliminated any impact to walls or tile to replace old valves and faucets. He and his team completed the work on time and were neat and professional and results were better than I expected. There was no damage at all to what was old tile. I subsequently had him assess an old water heater and decided to replace it. It had to go into a very small areas and be upgraded to code and he was able to solution the replacement to fit perfectly in the limited space. Previously on the project we had noticed a periodic odor of gas but no one had verified a source. Keith identified a leak in the area of the furnace right next to the water heater. We had decided to upgrade the furnace and AC and again Keith and his team were able to get an order in quickly, get the install done exactly as committed and fixed the gas leak in the process. Based on the quality of work performed in each case and the expertise of the team I hired Plumbing Tree again to assess an old furnace and AC at my primary residence. The furnace had been failing at the end of the winter but I waited for summer to replace and it had deteriorated and was not safe. Keith evaluated and gave me two options and was able to get the order in immediately after I decided to go ahead. He scheduled the install within a few days. His crew was on time and completed the install of furnace and AC in one day. Again they were neat, efficient, described all the changes from the old furnace and thermostat to the new and answered all my questions. Everything has been functioning just as I expected for both heat and AC. I recommend Plumbing Tree for these services based on quality and reliability - also cost was competitive and the team they used had the expertise required. Additionally they were easy to work with and I plan to use them again on another project. Thanks Keith and team- I appreciate the quality work!"

FAQs for central a/c service or repair projects in Boulder, CO

A condenser fan motor is a crucial part of your air conditioner that prevents the compressor from overheating. It pulls heat from your AC unit to cool the refrigerant moving through the condenser coils. This allows your system to blow cool air and keeps everything running smoothly.

The most common causes of AC fan motor failure include loss of lubricant in the system due to overheating and a rusted or leaking run capacitor. Poor lubrication can also cause failure in the belt drive, which may impact the AC fan motor. Weather and electrical components can also affect your AC. For example, a storm could send water into your motor windings and damage the internal components.

Air conditioner fan motors last about 12 years on average, though they can last longer if maintained well. This includes keeping them clean and cooled as needed with annual air conditioner checkups. Routine maintenance is essential to catch AC fan issues early. An HVAC inspection can cost between $70 and $500, while AC cleaning services may range from $100 to $400.

A broken AC fan motor may need replacement because this part usually can’t be repaired. Several things indicate it’s time to replace your AC fan motor, including buzzing noises, a constantly running fan, unusually high energy bills, or an aging system. If you notice these signs, call an HVAC pro for help before the faulty motor starts to strain other parts of the AC system.

There are clear warning signs of a bad AC fan motor, including unusual interruptions in the fan operation. The motor might be malfunctioning if you hear weird noises like grinding or rattling or if the fan continues to spin when the unit is off. These indicators compromise your AC’s cooling performance and increase your energy costs. Addressing these issues immediately by contacting a trusted HVAC professional prevents further damage and safeguards your HVAC's efficiency.

Replacing your AC fan motor takes a professional one to four hours. The technician will start by assessing your system and safely removing the damaged motor. If a new part needs to be ordered, it might take a few days. Once the part is available, your pro will install it properly and make sure your system is running smoothly.
