    Scheduling the appointment for my duct cleaning was a breeze. Maria was very helpful and even…read moreassisted with a last minute reschedule from my side. There was no attempt to upsell and the promotional rate was offered. Paul Boyd, who is the owner is a certified and knowledgeable gentleman who is an expert in his field. He did an energy audit and identified areas to improve efficiencies. He also highlighted areas that were good, which is not something most businesses do. At no point was there a push to sell or upsell. His main focus was to ensure that the customer got the most from his visit. Will be using their services to fix some of the issues identified. The duct cleaning was scheduled for a different day. The techs arrived early and were very efficient and thorough in the job they performed. The work and cleanup was completed to my satisfaction. The pricing for the duct cleaning is competitive in comparison to other companies in the market. I highly recommend the services of Climate Doctors for your duct cleaning and sanitation. The superior ratings online are totally reflective of my personal experience with them.

    I received almost an immediate response to my inquiry. I spoke with someone on the phone who was…read morevery knowledgeable and they were eager to find a way to meet my aggressive timeline requirements. Darell showed up on time and got right to work. They did a fantastic job and they were very careful as they worked around my home and personal belongings. After the cleaning, I had a question regarding one of the filter sizes and inquired about before and after pictures. I received a follow up from the actual owner of the company after hours, who was eager to share all of the finer details of the service. He then proceeded to offer to come out and do a free energy audit at my home. This is the company you wanna do business with. Great service excellent follow up and they had a better price than the other company I had been contacted by.

    I chose Green Collar for my City of Austin Weatherization service. I was hesitant, and called the…read moreoffice to ask questions about the business. Cord spent about 20 minutes answering my questions about how long they had been in business, how they would handle unexpected problems, and what I could expect. The owner Ron came out for the evaluation appointment and he also explained more details of the work they would perform. The installation of new ac ducts went very smoothly and the workers cleaned up after finishing each day. I would highly recommend Green Collar to anyone needing duct replacement or repair.

    As we head into this cold snap weekend, 10/10 appreciation for Green Collar!! They revamped our…read moreflipped home's rather chaotic HVAC system over the past three weeks in conjunction with the City of Austin/Austin Energy rebate program for energy efficiency improvements. The owner of the company provided our estimate, the team arrived within the time windows predicted, they were competent and courteous, and they did a *fantastic* job modernizing our system to heat quietly and evenly throughout. They added a vent to a bathroom that had been inexplicably left without one, improved the insulation throughout, and added an attic walkway for safety. We've been tolerating very uneven temps and noisy vents for the past 10 years, and I wish we would have discovered Green Collar sooner! It is *NICE* in here. I have no reservations about recommending Green Collar's services. Stay warm, y'all!

    We recently bought a historic home and suffered from heat in August and cold in November, even with…read morea new HVAC system. Ricky from ACT came to our home and performed a very eye-opening home energy audit. We were astounded at how many leaks we had and found out why our AC ran for 19 hours one August day. We had ACT out to totally redo our ducts and install radiant barrier. I could not be more pleased with the work that was done and we are already more comfortable in our home. Quote was reasonable and the work was done to perfection.

    We recently bought a house and we quickly determined we had a ventilation issue in the attic. We…read morehad 3 different roofing companies out to give us an idea on how to improve things but they were all stumped and couldn't offer a solution. Then we got our first electric bill and it was outrageous. I started Googling because K knew there had to be someone who could help us. I luckily stumbled across ACT and gave them a call. Ricky came out the next week and did an energy audit of our home. It was so extremely detailed and thorough - quite impressive. I immediately had faith in our issues being identified. Of course, we had a number of problems, but all could be resolved - hallelujah!! Ricky and his crew came back the following week and spent 2 days fixing all the issues. Broken ducts, soffit vents that were clogged, over a gallon of caulk to seal up various leaks in the attic, as well as the installation of solar vents on the roof. I can't pretend to understand how their scoring is done, but we went from a score of 285 down to 118. New build homes are required to be at least at an 80. While it was a chunk of money, I can already see the results and know the return on investment will be swift. So so glad I stumbled upon this company!!

    Since McCullough's 2018 installation of our Carrier HVAC system we have kept their annual…read moremaintenance contract: includes two separate annual inspections for AC and heating. The few system repairs have been covered by the contract, including emergency service over summer weekends. The consistent excellent year round performance of our Carrier system has proven McCullough's annual maintenance fee to be a great value, with peace of mind. Most recently, Linel discovered rodent damage of our AC ducts. After exterminators resealed the house Ian was immediately sent by McCullough to repair the ducts reestablishing the sealed system. McCullough stands behind their warrantied installation, HVAC annual inspections and works effectively with other contractors. We strongly recommend McCullough's installation, maintenance contract, and reliable customer support.

Overall we spent ~15k for the unit and install. We haven't gone 30 days without a breakdown yet. Each time it got qc'd, we were told everything was fixed. So far issues have been : - Badly installed drainage leading to water damage - Debris in drain - Refrigerant leak from install - Blown electrical unit. Every root cause was from something done incorrectly during install. We have damaged and unrepaired siding from install, water damaged drywall and paint from the follow on issues. Inspite of these repeated issues from install and failures, each call out for no AC has been treated as if we were calling for the first time and the only proactive communication was for ensuring the city code inspector passed it.
