Description of Work: We’ve used Brennan’s for years. I was particularly impressed with Rick. He went above and beyond, walking me thru some unused parts of my thermostat and showing me on Amazon which humidifiers to buy. He even left a cheat sheet for humidity levels. I was very appreciative of his professionalism and willingness to share his knowledge

Same day service call. Technician arrived during time projected; late Saturday afternoon. Quickly diagnosed problem, and replaced failed capacitor with "Turbo" capacitor on truck; this model can be adjusted to nearly any capacitance required - undoubtedly more costly than a capacitor exactly matching the fan motor, but a Do It Now truck cannot stock all models. From arrival to working in less than 30 minutes. Paid premium for weekend call for both materials and service call labor. Not sure I got the best price; but it was good and fast. Technical was professional and friendly.
Description of Work: Fan on A/C compressor was not running; requested a weekend service call.

April 2007 --I really liked the first service call where the technician assessed my needs (I originally was only going to replace the upper zone A/C and heating because the A/C under sized by the builder). However, technician determied the lower zone A/C was degrading. After 3 comparative cost estimates looking at different brands and SEER levels and considering rebates and various warranties I made a selection. In less than a week there were two installation teams working and the whole process was completed in only one day (finished mid-afternoon). The same technician returned to inspect and test the installation. Installation was very clean and workers mostly cleaned up after their work. Minor problems with clean up and return of attic access to original form was easily accomplished. They made arrangements for county inspections and the first round even dropped of a larger ladder for the inspector to use. When the inspector could not find all features he was looking for they came out again without charge and showed me the exact features the inspector needed and as a result the reinspection was less than 5 minutes. During a inspection visit in April 2008 the tech went the extra mile to investigate what I perceived as louder fan noise since the new A/C was installed. He determined builder had not properly lined some ducts for sound damping and with the improved air flow of the new unit there was more noise (very minor but noticeable).
Description of Work: Replaced A/C and heating in attic. Replaced A/C, added humidified, and improved ducting in lower level. (work was done in April 2007 so this includes 1 year of experience with the new equipment w/o problems).

I called Brennan to ask for a maintenance visit and an estimate on installing a humidifier on our heating system, as we were having some serious dry air issues. The appointment was scheduled within a very reasonable time frame, and the rep. who came out was very knowledgeable, involving me in the inspection to show me what he was looking at and why it was important. (As an aside, I signed up for an annual maintenance contract, involving two visits per year; as that was separate from the current project, I have not included that cost here, but I was so impressed with the maintenance visit itself that I felt we'd found the right company for regular visits). I received a quote for the humidifier; just one model fit in our tiny space, and scheduled the installation for my next available work-at-home day. The installers were prompt, friendly, and efficient, and we have been very happy with our humidifier.

Called and was told they would charge weekend rate for service (which I think is reasonable). Technician came and found out problem was due to a tripped circuit breaker (which we embarrassingly neglected to check before we call). He reset the breaker and "tightened a wire at the outside unit" and charged us $221 which includes the $141 weekend service cost plus $80 for the "extra" half hour that he spent to do all that. It turned out that we had a faulty curcuit breaker that kept tripping. My husband spent $12 on a new breaker the next day, replaced the faulty one and solved the problem. We have an annual service contract with them, but will most definitely NOT renew it when it expires. Very disappointed at the dishonesty.

THIS CUSTOMER WAS INFORMED OF OUR WEEKEND OVERTIME RATES PRIOR TO OUR SERVICE. OUR TECHNICIAN INDICATED ON AN INVOICE SIGNED BY THE CUSTOMER “FOUND BREAKER TRIPPED. TIGHTENED CONNECTIONS. IF FURTHER PROBLEMS, RECOMMEND REPLACEMENT OF BREAKER.” WE HAVE NO IDEA WHY THIS PERSON WOULD BE DISAPPOINTED. WE PROVIDED THE SERVICE THEY REQUESTED AND THE CUSTOMER DID WHAT WE RECOMMENDED. THIS IS A VERY UNFAIR EVALUATION OF OUR SERVICE.

Everything was well done and I am very pleased with their service. I had a question and they were there for me. They came the next day to see if everything was working as it should. They were here when they were supposed to be and were very professional.

They did a good job of servicing my A/C units before the summer. They were very professional and friendly. I call them prior to summer and right before winter so that my furnace and my A/C work perfectly. They always get my units working great and they are honest.

We did have troubles after the work was done as there was water in the drain that should not have been. We did a service call and they were out the same day to fix it. We got good response in that when we made the original call, they were out that day to look and the new unit was installed the next day. This happened in July which made us think that it might take some time to get a service call but we were proven wrong. It was a great experience for this reason.
Description of Work: Our tenants stated that the air was not cooling. Brennan was able to come out the same day as we called. We had them put in a new unit. Our town home is 3 stories with 3 bedrooms and 2.5 baths.

When we first bought the house, the inspector told us the heat pump was on its last legs. I called Brennan's to ask about it, since their sticker was on the unit. The salesman who answered explained how the unit worked, that there were two major parts, and either or both could be replaced, and gave me an idea of prices, all without pressure. Since we'd just bought a house, we couldn't afford to replace it right away. When we did two years later, I called Brennan's, and they were still as informative and low pressure. We eventually had them replace both units. It ended up being done on the first truly hot day of the summer, but the workmen replaced it in the heat, without complaint.

It was wonderful. All of the different technicians were neat, friendly, and knowledgeable. They gave me detailed information that was accurate (we had had other companies look at the system, and they gave more information). Our new system was installed neatly, and works better than I could have imagined. We are thrilled.
Description of Work: We had a technician out for a cleaning, our first in this new house, and realized that our unit was 27 years old. We subsequently had our entire HVAC system replaced.
