  • What should you ask a company

    When you need to have work done to your heating, air, or duct system, don’t simply throw a dart at the phone book. Take a little time to talk to a couple of companies and “interview” them. Asking important questions can save you time, money, and aggravation. What should you ask? Here are five important questions:


    1.) Do you charge for estimates?


    Ask the companies you contact if they charge to provide an estimate and if so, how much? This is important information for you to know upfront because if they do charge, that means you’re locked into spending a certain amount whether you have them fix the problem or not.  We do not charge for estimates.


    2.) Do you use employees or subcontractors?


    Someone from the HVAC company is going to be in your home, and its important to be sure that you can trust that person. You should also ask if the individual, whether they’re an employee or subcontractor, has undergone a background check, drug test, or some type of verification. Its also a good idea to make sure the company is insured. Don’t be afraid of coming off as overly protective - after all, this is your home and your family.


    3.) What are your credentials?


    If you’re going to be paying a company to fix your heating, air, or duct problem you want to make sure they’re going to get the job done right the first time. Ask how much experience they have, what kind of training they’ve undergone, and if they’re licensed.


    4.) Do you provide emergency service?


    Unfortunately, most heating, air, and duct problems do not happen at convenient times such as during business hours. You’ll want to make sure the company you’re talking to has emergency service or you could be spending a very long weekend without heating or air conditioning.


    5.) What products do you offer?


    The HVAC technician your dealing with is the expert, and you should definitely value their opinion when it comes to picking out a new heating and air system or product. However, don’t hesitate to ask a lot of questions and compare all the different products available. While the technician is the expert on the actual products you know your family and lifestyle better than anyone. In addition, make sure to inquire about warranties on any products and on the labor.

    When contacting HVAC companies, treat it like an interview. Don’t be afraid to ask tough questions. After all, you aren’t just being nosy - you’re trying to decide if they’re the right company for the job and if they are, you’ll be paying them. Jim at Valentine Mechanical Services is happy to answer all of your questions - just ask!  We strive to provide the best possible experience for you. Go ahead,

    I recently was called, on saturday, to a customer who's furnace was not working. He explained that someone else had made repairs to the blower motor but now the furnace was shutting off on an entirely different code. Upon arrival I found the furnace off and a trouble code was being flashed on...
    I've been working in the home heating and cooling industry for more than 30 years. Over all those years, I've seen many products and techniques come and go. Of all of those things, the one that never seems to change is the premature replacement of home systems such as furnaces and air...

    I"d like to correct an assumption several homeowners have.  Air is not like toothpaste! That is to say that you cannot close off vents in the basement and expect the air to come out upstairs.  A residential furnace or heat pump does not have the power to do that. I have seen on numerous...

    Jim is very professional and knowledge. There was something wrong with our heater. We called another company at first and they came three times and didn’t even find the problem. Jim came the same day I call him, and found the problem in only 20 minutes! Highly recommend him!


    Qasem AbuSalameh - West Chester


    Jim was a great professional, he do his job till the end and will always stays behind his work!!!


    Jessie Robertson - Liberty Township


    I feel much more informed about our system and appreciate the work and kindness he took in his work. We just got back from vacation and were in desperate need of help as our air was not working at all. Jim showed up and gave it to us straight, helped refill the older system and even came back afterwards and gave us a little bit more refill. I feel much more informed about our system and appreciate the work and kindness he took in his work.


    Liz Ferris - Liberty Township


    Amazing service! Needed help on a Sunday with my air conditioner and he was available right away. Highly recommend :)


    Allie Theiss - Liberty Township


    Yes yes yes, most reliable and honest mechanic! SAME day service


    Yes yes yes, most reliable and honest mechanic! SAME day service, twice!


    Shout out to this business. A couple weeks ago my 86 year old grandmother got scammed by another guy and was without air conditioning for a week. This guy came the same day and was able to fix it and even gave it to her completely free because of how terribly treated she was by the other company.


    Today I had the same part go out on my AC. I called around and the soonest other companies could come was tomorrow. Jim came the same day and was able to fix it! Reliable and honest man, I highly recommend him!


    Eric Sanderson - Liberty Township


    I highly recommend him


    Our AC broke down when it was 90 degrees outside. Me and my wife really wanted to fix it as soon as possible because we have 3 dogs and 2 cats that have to be locked up when we are at work. We called Valentine and he showed up within 30 minutes, fixed our AC, and was very nice and professional. I highly recommend him


    Sean Costello - Mason Ohio

    He is by far a credit to his profession and the community he serves.

    In recent years Jim Valentine has proven to be the "Go to" guy for many home repairs. This includes HVAC as well as many other needs. He is by far a credit to his profession and the community he serves.

    Jim is a fellow veteran and I have always trusted his suggestions, decisions and skills on my home repairs ..

    THANK JIM... Semper Fi


    Katie Day - Liberty Township


    Highly recommend!


    Very fast and efficient service. Highly recommend!


    Nic Y - Milford Ohio


    We've always had excellent service from Jim Valentine, and would definitely recommend Valentine Mechanical.

    Jim has serviced our old furnace and AC for the last few years, and he kept both of them going through various repairs (we wanted to wait as long as we could to replace them). He just installed a new Trane furnace and air conditioner for us, and we couldn't be happier. Jim always explains the repairs he's doing and why, and he walked us through the installation of the Trane system, as well as how it works and what makes it more efficient than what we had. The Trane is so quiet that we don't even notice when it comes on, and it cools the house much better than our last AC. We've always had excellent service from Jim Valentine, and would definitely recommend Valentine Mechanical.


    Bob Brumberg - West Chester


    Very professional and reasonable pricing.

    As luck would have it our furnace stopped working during the coldest stretch we'd seen in a while. Jim happened to be available same day and was here within an hour. The fix ended up being quick and saved us from a frozen house. Very professional and reasonable pricing. We'd never had an HVAC issue so I'm glad we found someone we can go back to.


    Christian B - Liberty Township


    Great service, very friendly people. I will definitely use them again if I have any more problems

    My AC broke today and even though their schedule was full they still managed to fit me in. Great service, very friendly people. I will definitely use them again if I have any more problems


    Mary L DePuy - West Chester


    I would recommend Jim's services to anyone who has a AC problem!


    My husband and I bought this home a year and a half ago. We did NOT expect to have a big repair job for the house so soon. But it turned out our AC unit was going bad and tripping our circuit breaker and it needed to be replaced. The AC prices I got from the first company we contacted were beyond what we could afford . And not a single company I had called was able to come up with a better price or solution... Until I contacted Valentine Mechanical Services. Not only was Jim willing to come by and check out my AC problem the day I called him, he was able to give me a MUCH cost effective solution that suited our needs. He was professional and got the job done promptly. I would recommend Jim's services to anyone who has a AC problem!


    Paul Dadian -Liberty Township


    I highly recommend Valentine Mechanical Services to everyone that reads this post. Do not let anyone work on your home mechanicals other than Jim...period. He is a Gentleman, He's Honest, He's Service oriented and extremely "Reasonable"!!!


    I found my Trane furnace blowing cold air on Jan 22, 2013 at 5:45pm... it was 7 degrees outside. I made it through that night and called a local Machanical repair company the next morning; Valentine Mechanical Services... Jim Valentine answered the phone and said he could be there within a couple of hours! His rates were more than reasonable and his service and professionalism was off the charts! The problem, as it turned out, was complicated but Jim took control and fixed my Trane XB90 gas furnace within 3 hours. I highly recommend Valentine Mechanical Services to everyone that reads this post. Do not let anyone work on your home mechanicals other than Jim...period. He is a Gentleman, He's Honest, He's Service oriented and extremely "Reasonable"!!!

    Jim Valentine will not let you down, call today


    Jim Valentine installed a Bryant system in my home and repaired the air flow to my 2nd story by fixing some seriously questionable work done by the previous home owner. In the summers my 2nd story would often be ten or twenty degrees above the 1st story. This is no longer the case. Now the difference between the two floors is always within a minuscule 3 degree difference as I still have additional work to do in the house. I thank Jim and his contractors personally for improving my quality of life exponentially. If your home suffers from imbalanced temperatures or air flow issues and is generally behind the times HVAC equipment wise, then VMSI is the place for you. Jim Valentine will not let you down, call today

    You take care of all our heating, cooling and maintenance needs.

    Just wanted to say thank you for taking such good care of our center. It’s wonderful to have someone as reliable, talented and trustworthy as you are to turn to when we need repairs and assistance. You’ve definitely got us spoiled.

    “I first became familiar with Valentine Mechanical Services several years ago at my place of employment."


    The company was performing HVAC work for our school, and as an owner of multiple residential property, I was searching for a reliable company to assist with my own HVAC needs. Many times since then I have called upon Valentine Mechanical Services, and every time I have been satisfied. You can expect prompt, courteous service each time you call. It’s nice to know that your mechanical needs (either large or small) will be completed in a professional, comprehensive manner. I have and will continue to recommend Valentine Mechanical Services to my friends, family, and business contacts. "

    We were extremely pleased with the service we received from Jim Valentine.


    Our AC went out on Memorial Day weekend, the hottest weather so far this year, at that point -- 93 degrees. After spending a miserable night, we were ready to do anything to correct the problem. We called Jim Valentine. He said he would be there within an hour, and he was. He quickly discovered that a capacitor had gone bad, so he replaced it. Total time for the repair: about half an hour. Although he wasn't going to charge us for a full hour of service, we paid him for an hour anyway. It was less than a hundred dollars, including the part. Who else would come out on a holiday, repair the problem and charge less than a hundred dollars? Jim has earned our respect and loyalty. We will definitely call him first when future needs arise.


    The Abbatiellos - Most Definitely will use VMSI again. VERY Happy with the service, professionalism. SAVED us a boatload of money!
