I worked directly with Jerred and he was amazing! He came out (On Labor Day!!!) and 100% saved me. It was warm, and I had a bunch of family in town for the holidays and an extremely hot house wasn't going to work for me. I called Holtzople around 10 am, they answered the phone live (only company I could find that didn't go to VM) and Jerred was out within a few hours. He was very informative and quick (which was important because, no offense to Jerred, I prefer to spend the holiday with my family instead of him) and didn't even charge extra because it was a holiday. Turns out I had a contactor that went bad (he showed it to me... it was literally burnt at the top) and was a pretty quick and easy fix. I am VERY happy with the customer service, pricing and speed of service. If you have an issue (especially on a holiday) make sure to call Holtzople and ask for Jerred!

I'm glad I did. They responded in less than an hour, and a half-hour after that, the air conditioning was working again. The charge was very reasonable, and I was advised on steps to take to avoid problems in the future. I've since signed onto a service agreement to have Advanced Air Services provide regular maintenance for my HVAC system.

Excellent service and genuinely nice people. They have become my go to for HVAC services!read more

We got several estimates for replacing our furnace and a/c. This was the one company I didn't feel like I was dealing with used car sales men who were trying to rip me off. I felt like they were honest about what I needed, didn't try and up sell me things I didn't need and respectful when I asked for time to consider my options. Once we decided to go with them they scheduled us with in a week. The install was fast and I barely even knew they were in the house. Everything is working great and we are really happy that we decided to go with a local company. I am very picky and do extensive research before any major purchase. Frederick Heating and Air has excellent reviews, provide a great value, excellent warranty and professional service.

But pricing was very high and their rep did not itemize the services needed. Nonetheless we decided to go with Tim Kyle. In the meantime to get the price down we omitted nearly everything with the exception of just one dimmer switch and one ceiling fixture. Asked the rep to revise the contract and resend with updated pricing. He refused and said he would just update our price later after he came out to get the work done. Huh?How can we schedule work without knowing the cost? Kinda sux but ended up finding a different company that charges per hour + parts and are pleased with the outcome.

My husband and I…read morewere lucky enough to need his services on the coldest day of the year when our heat pump stopped working :( Doug came right over, diagnosed, even drove straight to Westminster to get the part, and had us up and running within a few hours. A few years back, same scenario at a rental. His services have always been of quality and very affordable and I can't tell you enough how much we appreciated his promptness! Not only does he do residential, but he also does commercial. I recommend Kiser Mechanical to my friends and family all the time.

I was booked for that Monday! The day of my appointment, I was called several hours before my appointment to say they had an earlier than expected time slot and wanted to know if they could come now. Unfortunately I couldn't do earlier than scheduled but appreciated them asking! My time slot was 4-6 pm. They showed up at 4:05! Wow! I can't tell you how many times companies give time slots and show up hours AFTER the time frame. But not Markool! They are on it! Jorge and Jose were my technicians. They were both very friendly and went right to diagnosing the issue. After about 30 minutes, they figured out I needed Freon. I asked the pricing and they had a tablet to look up the pricing right away. If you need Freon be warned it's expensive! Not this company's fault though it seems to be commonly expensive when I looked online out of curiosity. These two technicians were knowledgeable and explained everything. They were super polite as well. They emailed me my invoice with pictures of everything they did today. I highly recommend Markool for your cooking needs!

Can no longer recommend!!!…read more I had Hotzople for over 7 years since I moved into my home. I am very very disappointed in how techs handle certain situations and actually found a MAJOR issue in open ductwork in unfinished basement that NO ONE from this company even bothered to look into or do any sort of testing to find out root cause....when I stated that my husband and I smelled musty, dusty smells and were affected by allergies, I was told 'this is normal' and nothing else. ???? You pay almost $400 for their better tier plan for HVAC service, and what you get is little to NOTHING. The tech barely does anything and if you state you have issues, they blow you off. Lazy!!!! I hired another company to install a new system, wasn't about to give this company anymore of my money. They found a cracked UV bulb that Hotzople had replaced, my filter area was jacked and should have been fixed a LONG time ago, and I today found an extra tubing coming off my duct in basement that was never capped off, thus rendering my entire system basically non functional -- at least very wasteful..... I cannot believe this has been for 7 years and Hotzople NEVER once checked for any duct work issues, or anything or ran any tests, I was systematically blown off, these guys do they BARE Minimum and ONLY care about collecting their yearly $s for maintenance. I highly suggest everyone EDUCATE yourself about HVAC before hiring ANYONE, these companies anymore have become greedy, they don't care. I was also told I had issues with my old system, but never was 'shown' WHAT those issues were fully. Trust is a BIG thing if you want to keep your company running....these guys 100% lost my trust and now someone else will be getting my money!
