  We don't have a huge house. It was built in 1996 and about 18 months ago and decided if we're going to stay here, we should update a few things. The heat pump was working OK- one rebuild years back - but close to 30 years is reaching the avg. Service life of a heat pump/furnace. I originally got Brennan info at Costco, a company I trust. I was a bit anxious - no matter what, it was going to be a chunk of change. The sales rep who came to the house was a good guy. , Explained everything, discussed a few options and zero pressure. It was a big number (for us) but we went ahead. The install was flawless. There's a big difference. I can hear and feel a better system at work. The digital thermostat works well and no issues. Included in the purchase (we paid a bit extra) was a vent cleaning and three yearly maintenance check ups. I kept putting it off. Two rooms in the house are packed with stuff and I didn't want to move a lot of stuff to access vents. We're slowly downsizing; some physical challenges; unexpected job change; vacation; new puppy - whew! Even though it was past the scheduling point of a year, the Brennan folks said no problem. This morning a very friendly dispatcher called to verify we were home and the tech called to say he was on the way. He did the vent cleaning fast but good, explaining every thing. The second tech arrived for the maintenance and same deal - friendly and efficient. Its a lot of words that boils down to a total recommendation. Every single staffer was friendly and helpful. Like I said - this is a big investment for most of us. I think I made the right choice.

  Worst service ever. Had to be without AC the whole summer due to their inefficiency to identify the problem. No call backs after escalating and rude reception when lodging a complaint. Still facing the issue with numerous calls, wait times and going in circles. The team do not have any notes from the prior technician, which makes their service terrible.

  FRAUDULENT AND DECEPTIVE COMPANY. BEWARE. Wouldn’t stand by their tech’s misplacement of an air duct relocation. Recommended a $800 cooling system repair that a second opinion deemed 100% unnecessary. Filed a BBB complaint and working with Washington state L&I and Attorney General’s Consumer Protection division. There’s a special place in hell for these guys if they do this to some unsuspecting elderly person on a fixed income. Shameful.

  I had Brennan install a new furnace and heat pump in July 2017. Unfortunately, my experience since then has been disappointing. Just one week after installation, the system stopped working and required a service call while we were out of town. They fixed it pretty quickly. 2021, the fan motor and blade failed and had to be replaced during a stretch of weather that was over 90 degrees. The parts were under warranty, but I still had to pay labor costs. To minimize the number of people coming into my home, I specifically requested the same technician who had previously worked on the unit. I was told the appointment would need to be scheduled further out to accommodate that request, which I agreed to despite the heat. When the appointment day arrived, the technician who showed up was not the person I had requested. I ended up waiting longer for no reason while dealing with temperatures above 90 degrees. 2025, the thermostat failed during January when temperatures were freezing. I was told only a Lennox thermostat would work with the system, resulting in a replacement cost of about $1,000. It took roughly a week to get a service appointment and another week for the part to arrive. During that time, I had to call Brennan myself to find out whether the part had come in. 2025, I called to schedule maintenance because I never received the reminder calls I had received in the past. While waiting for the appointment, the A/C stopped working. Once again, the fan motor and blade had failed. The parts were covered under warranty, but I paid another service fee plus labor charges. Most recently, when I called in June 2026 to schedule maintenance, I was told the earliest appointment was July 31. I asked why I had not received a maintenance reminder and was told those are only provided to customers on a maintenance plan. After reviewing my account, the representative discovered that my previous visit had only been a repair and not a maintenance service. What frustrates me is that no technician informed me of that at the time, discussed any maintenance recommendations, or explained that my annual maintenance had not been performed. Since Brennan only performs maintenance annually, that meant my system went two years without a maintenance inspection, and I had no idea because no one communicated that to me. After I hung up from scheduling the July 31 appointment, I immediately started calling other HVAC companies because I no longer have confidence in Brennan's service. I spent approximately $20,000 on this furnace and heat pump system and expected better reliability, communication, and customer support. Instead, I've dealt with multiple breakdowns, repeated labor charges on warranty repairs, long waits during extreme weather, and poor communication regarding maintenance and service. For a company that installed and has serviced the system from the beginning, I expected a much higher level of customer care.

  Terrible Service and Horrible Company We are completely dissatisfied with our experience with Brennan and strongly warn others against using this company. Our family purchased an air conditioning system through Brennan for nearly $30,000, expecting professional workmanship, quality engineering, and long-term reliability. Instead, what we received was an installation that appeared rushed, careless, and completely lacking in proper design consideration. The hoses and wiring were run directly through the house with little regard for aesthetics, engineering fit, or overall quality of installation. It looked more like a temporary shortcut solution than a professionally installed high-end HVAC system. To make matters worse, the system failed after just 3 years and 9 days — literally nine days after the warranty expired. For a system of this price and supposed quality, this is completely unacceptable. When we contacted Brennan for support, the experience only deteriorated further. The technician sent to evaluate the system was sub-par and ultimately recommended using a sealant solution that would effectively shorten the lifespan of the unit rather than properly addressing the underlying issue. Instead of standing behind their work or offering meaningful support for a clearly premature failure, Brennan seemed more interested in pushing a temporary patch job and moving on. At every stage of this process, Brennan has demonstrated poor workmanship, poor customer service, and a complete lack of accountability. We deeply regret trusting this company with such a major investment in our home. We will absolutely be recommending to Costco that Brennan be removed as a service provider, as no customer spending this kind of money should be subjected to this level of incompetence and disregard.
