I have been using Williams Heating & Cooling for 3-4 years now, mostly for regular HVAC maintenance checks, although once I did have a semi-emergency. They were able to come by my house the next day and do the repair to help ease my mind. I usually have the same technician perform the services and he is always friendly and professional. As of now I plan to keep using them for any future HVAC needs.

They gave me one of the best quotes, and responded to my inquiries very quickly. They were amazingly professional and completed the work when they said they would. They even helped me find another professional to install the security cage I needed as they didn't offer that service. They vouched for him and he was equally professional.

I had an A/C condenser that was acting iffy. I had another company come take a look. The A/C was running at the time and they couldn't find the problem. But then the A/C acted up again, and I called Williams Heating & Cooling. A technician came out the next day, found the problem and fixed it in just about 1/2 hour. Very impressed. Not all companies deliver the same quality of service even if they are rated 'A' here on Angie's List. The 'A' rating this company has earned is well deserved.

We are happy to take care your calls and help you with your HVAC issues. Besides, air conditioners can go out at any time of night or day. Sometimes, that warrants a phone call or Face Time! We were able to walk through the issue, attempt some trouble shooting measures. Even though it still warranted a service call, I'm glad we got you taken care of efficiently and effectively. Thanks for being awesome customers...

They had to replace a part that was broken and they did not charge me for it. Because it was caught doing the Winter Tune-up. They are type of company that is honest and you can trust to always do the job right. The service man was very professional & polite letting me know what had to be done. This is so helpful to Senior Citizens on a fixed income.

OUTSTANDING !!! From the initial phone call, through the inspection, installation and then running me through operating the equipment, the owners, and installers were AMAZINGLY friendly, and STUNNINGLY professional!! No hard sell-just a concise knowledgeable offering of options. They all were FANTASTIC, and made the horrible situation of having to replace A.C. and furnace much less stressful!! QUICK to give inspection and estimate, and then squeezed me into their schedule!! HIGHLY RECOMMENDED!!!!

Description of Work: My AC unit went out overnight. I called in the morning and a technician came out within a few hours. He quickly saw what was wrong and replaced the part right then and there. To my relief, it turned out to be a quick inexpensive fix.

PERFECTLY!!! The bid and scope of work was EXACTLY what was promised. They even let my son know that he needed a new pad for the outdoor unit (which he knew was broken) but the other bids he received did not even mention this. Plus, Williams had financing available where the other companies did not. Also, the AC broke the night before my son left for vacation and it REALLY needed to be fixed but Williams treated me with courtesy and NO BIG UPCHARGES. Their bid was competitive and fair. The technicians (Justin and David) arrived promptly and were very professional and polite. They covered the carpeted areas with drop cloths and went to work. They were so quiet that I did not know they had removed the indoor unit until they were taking it outside. When they finished their work everything was put back in place as though they'd never been there, the old units were hauled away, and they walked me through all they had done for final approval. This is the only company I would ever have in my home or recommend in someone else's home.

They like to make excuses as to why something is not their fault or why they won't warranty something or why what they said last time was correct at the time, but things have changed since. They were great to work with when the installation occurred, but have been a nightmare ever since. Save your money and go someplace else; unless you like countless excuses and poor workmanship. I hired a reputable company to come out and fix the system - and another company to come out and repair the damaged ceiling.
Description of Work: We hired Williams Heating and Cooling to replace an aging HVAC unit on third floor of our home in late 2014. Since that time, we have regretted hiring them every step of the way. We have had nothing but issues with our system. They installed it in the Fall, so the first time we turned it on was the following Summer, it didn't work. Turns out they did not charge it with Freon. They have been out several times since then to fix issues that they didn't do right the first time (like install return ductwork, they said it didn't need it when it was originally installed). This last time, the condensation relief hose backed up causing water to seep into the ceiling of the floor below. They said they would not warranty that or repair the ceiling because cleaning out the hose on an annual basis was considered "routine maintenance." We have had this house for six years and our primary system is a 15-year old Trane, we have NEVER had that hose cleaned and it has NEVER backed up and leaked anywhere.

Mr. [Member Name Removed], I'm glad we have a chance to reply to your many reviews since you've hired us in 2014. First, let me apologize that you've had such a horrific experience with our company. In the six years of our existence, we've never had such a review from any customer-either in person or via review sites such as Angie'[Member Information Removed] List. When we installed your third floor system back in 2014, and the installation was complete, you and your wife were disgruntled with our clean up process. In response, my sister and I (the co-owners of the company) concocted a cleaning solution and came out to personally wipe down your walls and also port over a vacuum to remove the amount of dust and wood chips that remained on your carpet. We were happy to do it, because a happy customer is what we strive for! Next, when the unit wasn't cooling like it should during the hottest days of the Summer that year, and humidity continued to build on the upper level of your home, we came out multiple times at no additional cost to you, in a prompt manner, to resolve your a/c problems. We sent our service techs out, always working with you, until we had to ultimately bring a manufacturer'[Member Information Removed] rep to your home to help us solve the mystery. When we finally realized the return issue that was occurring, we fixed it at that time. We don't promise to be perfect, but we do promise to uphold our word and stick to what we say we'll do. And that is, to make sure your system runs the way it is supposed to. This has been 3 years ago. You called us earlier this week to come back out and fix a problem that has apparently been going on since we installed the unit. While it is no longer under labor warranty, it is under parts warranty. While you mention that there was a condensation relief hose back up problem occurring, that could be caused by so many different things! A third floor system will experience different issues than your main floor, older Trane system. We also would've been happy to come out and assess the problem at the earliest availability our service schedule would allow. We understand you are trying to sell the home, and we would've liked to handle that issue for you in the promptest manner possible. We are sorry it wasn't as soon as you would've liked. And yes, we recommend, according to manufacturer guidelines, that your HVAC system is maintained 2 times a year (annual maintenance), once in the heating season and again in the cooling season. This ensures proper operation of the system and anything that needs to be adjusted, tightened or cleaned, is done at that time to greater ensure reliability of that system throughout the hottest and coldest days of the year. But, we have not serviced your unit since its install date, so we have no idea what could've caused the problems you were most recently experiencing. We regret that this relationship did not work out for you and that you part with your home disgruntled with our service. However, it is our priority to make sure that each one of our customers is taken care of, that we are punctual, attentive, and we are always professional. We are sorry you don't feel the same and wish you all the best in the future. Joy and Jane Co-Owners of Williams Heating & Cooling

They could not have been better to work with. Both times they have some out to service my two units, they were prompt, courteous, and professional. Above all, they were very honest. I am a new home buyer, and they gave me peace of mind. I will always go back to them. Their prices are also right in line or cheaper than the competition. They are a great independent company, doing things the right way.

I contacted Williams at about 8:30 AM and they were at my house in less than an hour. I let them know that they needed a ladder to get on my condo roof to see the air conditioning unit. They had it giagnosed in less than 10 minutes that I needed freon. They called me and gave me a price per pound. I did some google searches real quick and saw that the $85.00 per pound that they quoted me was a reasonable price. Also, their technician was polite and professional. I don't think he was there more than 30 minutes. I highly recommend them. Service fee was $75.00 and then 2.75 pounds of freon.

Williams Heating & Cooling was responsive, & professional. The repairman quickly diagnosed the problem & gave me a quote for repairs & replacement. While I opted for the quick fix, the 26 year old furnace broke on the coldest day this year. Williams H&C delivered space heaters to keep us warm overnight. The furnace team arrived on time the next morning & work diligently until the new unit was installed & working perfectly. I am extremely satisfied with my new furnace. The owner provided detailed explanation of all options, products, & services. My wife was so impresses that she used Williams H&C this week when her dad's furnace broke. We are fans!

I contacted Williams on 03 November, and made arrangements for them to visit very promptly two days later, on 05 November. Matt performed the cleaning check and concluded the furnace was in very good working order. I also had my wife ask about installing a better humidifier on the furnace since our current furnace humidifier needs to be supplemented by stand-alone humidifiers. Matt explained how a forced unit could be installed, and gave us an estimate for the work. She felt comfortable and not pressured as Matt explained the humidifier work.

WOW! FAST! Bought deal on Tuesday, came out on Wednesday to check to see if there would be any problems, installed in 2 hours on Thursday. Joy and Jane were a pleasure to deal with on the phone. Actually spent a little more with them than some other deals for the same product because Joy took some time to explain how the humidifier would work and if it was a good option for my home. We are from Texas and have never had the need for a humidifier so it was new to us. Justin came out to install. He was professional, quick and took time to show me his work and explain how the humidifier operates and how to perform the routine maintenance. A+! Will use you again in the future.
