In my decision to try to use cheaper people to do my job. I wasted 7 months time waiting for small contractors to come. They pushed the job to later date. And others came estimated and scheduled the job and never showed. I dedcided to call Kowalsky's. I explained my situation and told them the importance of this job. We have a family of five we had remodeled a new home for my family.

And we were just waiting on a few heating and hot water unfinished projects. To move in. I told them that my youngest daughter is fighting for her life against a DIPG Brain Tumor. We are trying to let her enjoy her new home. Buddy called me back two days later and had an estimator there the next day. That was Friday. I called in on Wednesday. On Tuesday Buddy called me and had two very professional mechanics at my house whom finished the job in a few hours.

Everything about this business is professional. When the estimate was agreed upon all I had to do was open an email, click a link and make my deposit from my phone. No waiting. At the end of the job the installers said I could mail my balance in or use the payment portal in my email again. No pressure what so ever over the money involved. Amazing business. Local people great attitude. 5 stars

Speedy getting out to my house and I understand charging for the time to come out, but then wanting to charge me almost $2,000 for 16ft of flexi hose is sort of rediculous. Service: Ductless heating & A/C services

My water pressure tank spontaneously sprung a leak. I called them and they made me an appointment right away. The technician came to the house on time and prepared. They replaced the tank same day and now everything is running smoothly. Professional, prepared, and great service!

I had a great experience with Kowalski service. My A/C went out a few hours prior to a household of weekend guests. Kowalski was able to come out within an hour and had my unit running within 1/2 Hour. They were professional, , courteous, and explained exactly what was wrong. I was/am so thankful to have a reliable HVAC company I can trust.

Pros: Technicians are nice and courteous, can pay by credit card, normally can get to you with a day or two, prices are reasonable and they only charge one call-out fee if they need to return. Cons (for my experience): For the three instances I requested Kowalski HVAC assistance they had to return at least once and up to three times to fix the initial complaint. 1.

Summer of 2019 upstairs air conditioning not cooling. Came out and said there were no issues and they could not duplicate my concern. Billed me and I paid for their time. Within hours the AC was not blowing cold again. I requested they come out again to look at it. This time the tech found a problem. The problem was the expansion valve near the coil in the attic unit. Billed me for the repairs, I paid. 2. December 2020: My four zone minisplit/heat pump in my metal building stopped producing heat.

I called Kowalski's HVAC to check it out. Two great technicians came out and after about an hour of checking everything out they concluded one inside unit out of the four was stuck on AC mode while the other three were on heat. Billed me for their time and I paid. No problem yet. 3. Three to four weeks after issue"2" above the outside unit (condenser coil) kept heavily frosting over and the fan would never turn off.

I called Kowalski's and requested they come check it out since the unit was acting up after they worked on it. A technician came and told me the refrigerant was low and there was a leak at a fitting going into the outside unit. He claims to have tightened the fitting and re-filled the unit's refrigerant. They billed me again and I paid again. Three to four weeks earlier the two techs were messing around with the unit.

You decide if the two events are correlated. 4. AGAIN. the unit was still frosting over heavily and the fan would not turn off or cycle. I called Kowalski's HVAC and aggressively complained and demanded they come out no charge and fix it. Finally after abut ten minutes the service coordinator/manager agreed to have them come out at no charge to look at it again.

The technician was at my house for an hour nd concluded it frosting over was normal operation after all these calls and back and forth. Ironically the unit does not frost over any more and the fan cycles ever since he was here for an hour and concluded it was normal.

These guys are lazy! I originally placed a call to the plumbers to fix some worn out straight valves under my kitchen sink that are welded on. I told the receptionist my problem and she was very kind and told me that someone would pass by tomorrow to take care of it. To start, what I had originally thought was a one-man job (only one person can fit under a kitchen sink) required two workers.

They entered and took a look at the job before quickly telling me that they did not have the correct valve in their truck, even though I had provided all the necessary information on the phone previously. This was not all. After telling me they did not have the straight valve, they also said that they would not be able to fix my problem at all since there was "not enough room to weld" under the sink, which seems a bit improbable since that is where it was originally welded.

What they offered to do however was install a new faucet that I had purchased, without fixing the issue I had called about. Seventy five dollars just for them to show up, which they did unprepared, AND an hourly rate for TWO people all just to install a kitchen faucet which I could've done myself. In total, I paid $250 for a job that never got done.

It seemed like rather than showing up to do the job, they showed up, decided they did not want to work that hard, and took the easy way out. The only reason I agreed with this is because my wife works in a Covid-19 testing center and it is necessary for her to wash her clothes and herself once she arrives. I was expecting a bit more professionalism after all of the good things I had heard about Kowalski in my community.

Came to my house to inspect my heating system furnace. Told me the furnace was shot and needed replaced. The furnace is approximately 15 years old. Price to remove and install new gas furnace hot air heating system was $5,000. And then they charged me $300 for the estimate. Had two other heating contractors come look at the furnace told me nothing was wrong with the furnace and should last another 10 to 15 years. These people are con artists taking advantage of older people beware

Professional, timely, efficient. They fixed a problem we had been dealing with for years (and had a contractor in to fix but didn't) in about 2 hours. Highly recommend.

A+ Service! Our furnace stopped working in a cold week in January. They were very responsive, on time, and courteous. We did end up needing a new one and they had it installed quickly. The service men on both visits were very professional, on time, helpful and overall nice guys! The sales person was also very friendly and professional. I recommend this company and will use them again in the future.

I called for estimates and nice older man come to see the house. Said he would get back with an estimate. Never heard again. Called and they sent another man out.spent another hour. Showing him what was wanted. He said he would get back with estimate. Never heard. Emailed him next month and he said he would get back next week. Never heard again from either of them! Wasted my time twice for nothing!

I called Dents plumbing. They came and did the estimate, work and it was done. Professional. I never dealt with Kowalski again. They wasted months of my time and treat customers like carp! Must have inherited the place! Don't bother them.

Called for service, no water. Service guys and Barry were great. However, the lady that answers the phones is RUDE and NASTY. Due to her treatment of customer's, I will not use this company again.
