"very impressed----joe the estimator was very knowledgeable and not pushy-----gary the installer was super and very careful to clean up every little bit of dirt---mike who did the furnace tune was super ------------how often do you have a company so honest that when you ask to have a 20 year old furnace checked out----they do a very detailed check and show the details and they don't try to ram all sorts of repairs at you--they actually said everything is fine for now ( guess who I'll call when I need one }--they were right on par with 2 other companies I called for estimates----awesome job"

"Our nearly 40 year old boiler system had seen its last day. Steve with Guardian was easily accessible by phone, prompt, and helpful. He installed a new boiler and retooled the set up of our system. We re very happy with the service, speed of the install, and professionalism the guys showed. We didn t shop around much since we weren t interested in having too many people coming in and out of the house during the pandemic, but felt confident Steve was giving us good information and a fair price based on what we were told in the past and research we had done. I would certainly recommend Guardian to friends and family. I will update going forward if necessary since the system is currently a day old, but the house is as toasty as ever so mission accomplished thus far."

"They replaced both my furnace and air conditioner (coil and outside unit), removed and disposed of my old units, installed a whole house humidifier, and cleaned my ductwork. They were very professional and personable, and completed everything but the ductwork cleaning in one day. I wasn't able to be home for the entire project, but they raised and leveled the new air conditioning unit as I requested, and explained the functioning of the wi-fi thermostat before I left, and all the installation areas were clean when I came home. They completed the ductwork cleaning on a different date, and this service was also done very well. My only concerns or "complaints" would be that they used clean rounded stone beneath the air conditioning unit and I'm not convinced that it won't shift or settle over time; and they removed a vent that supplied heat to the basement so now the basement is very cold."

"Great Job, Mike was able to get to the property same day and complete full installation within the day. Worked late hours to make sure it was complete and kept in great contact from initial inspection until installation. Will definitely use for any HVAC services moving forward"

"Excellent! Sparky called a few minutes before the appointment to say he was running late. Once he arrived he quickly went to work and graciously answered my dad's questions. He even laughed at my dad's bad jokes. I had only planned to have him change the wiring for the exhaust hood to an outlet for the over-the-stove microwave I was going to install. While we had the stove pulled out, we decided to have Sparky add an outlet for the stove to plug into so it didn't have to plug into the one over the counter. Sparky didn't blink an eye at the additional work. He was a joy to work with and I plan to hire him the next time I need any electrical work done."

"Antonio was a pleasure to work with. He was very pleasant and knowledgeable, and answered all of the questions my husband and I had as well as explaining his process. He worked very quickly and efficiently and was finished well before we expected him to be. Price was reasonable, including an adjustment for a second heating system. Also contact and communication in setting up the appointment was good. Would absolutely hire this company again."

"They were able to come out and quickly help me install my sump pump and replaced the piping, which had been a non-professional job, fixing some issues and extra strain on the pump."
