Joe C is the Man! Very professional and knowledgeable. He kept me informed every trouble shooting step of the way. Parrish Services, Inc is definitely #1 on my list for all HVAC needs. Thank you! Also thanks to the young lady that booked my appointment! Sorry I can remember her name. She was very kind and found me an opening.

Christian arrived on time and thoroughly explained options available and the related costs involved, He was careful to ensure that we understood the problem, costs and fixes. He was a professional in that he performed a service at an honest price. We look forward to continuing business with Parrish Services again. Service: Light fixture repair

Beware! They use predatory practices to get you to agree to their services and their prices are astronomical. Had an emergency water heater flood at my house after hours. They pressured me into agreeing to an install for the next day without being able to review the invoice. They came out the next day and did the install (5 hours later than they said they would be there). Once I was able to review the invoice, I realized their price was $1000-$1500 more than other quotes I had received and they did not give me my 15% discount which I should have received for being an existing customer (which would've been about $550).

When I spoke to manager Joanne to bring this to her attention, she was extremely rude and refused to refund me the discount I was owed. I asked to speak to the owners and she refused to pass my complaint any farther up the chain. Please avoid as you will deal with rude people and pay much more than necessary.

My whole house Generac generator was showing a red light so I called for service from Parrish who I have a contract with to see what the problem was. They sent out Christian who was such a great and knowledgeable electrical service technician. He diagnosed the problem and set about getting me back to green light status. He was also very helpful in getting my mobile app for the generator connected to my WiFi. It was a truly pleasant experience and I came away knowing more about my product and the very nice person who serviced it. Thank you so much Christian and Parrish Services

Please do not use these people. They have predatory pricing and predatory tactics to get you to agree to the work. They took advantage of me when I was in emergency (water heater flooded). Later I found out their prices for water heater install are over $1500 more than 3 other companies I got quotes from. In addition they refused to give me the 15% discount I was owed even though I was an existing customer.

Manager Joanne was unprofessional and rude and should not be in customer service. My mother had just died and her water heater flooded at her home. I was in an emergency and vulnerable situation and they completely took advantage of me and then refused to make it right or even let me speak to an owner. Do not use! Compare pricing and you will see.

They came out to do a routine service and while here looked at the sprayer on my kitchen sink and a pop-up drain on a bathroom sink. They fixed the bathroom sink wrong, and I had to show them how to fix it. The kitchen faucet they flat broke, refused to take any accountability to repair it, and then severed our relationship because they knew they could not do it right. The routine maintenance report was wrong.

They said I had city water whereas I have well, and they said they did not flush the hot water system which they did. Of course the technician came without a hose so I had to lend them one of my hoses. They didn't flushed it right onto my black top driveway leaving chemical residue all over it. People involved were the owner, the general manager, the service manager and customer service. They are all very unprofessional and if you have any trouble they will simply dump you. At one point they also insist that I pay for the faucet they broken before they would come out to fix it again. Got to love crooks
