Tim was outstanding. It's easy to see he cares about the work he does. He did an extremely clean installation and went above and beyond just a normal installation. He fixed the poor installation of a humidifier, and brought both the furnace power switch and furnace/water heater flue vent piping up to code ... while hired to do an air conditioner installation. The AC was just installed yesterday and so far is doing a better and more efficient job than the 16-year old unit that was replaced. I am very happy with his quality of work and would highly recommend him.

The two man team was very professional and thorough. They completed a deep clean and service on the air conditioner and replaced the capacitor. We immediately noticed an improvement on the AC output and overall comfort level in the house. They also completed a diagnostic of the existing heating and cooling systems, giving us an idea of their expected life span and what we can do to extend their use.

Michael was amazing! From the time I created and posted my project it was only 24 hours until my air conditioner was back up and running. He was very professional and honest with us on the issue with our system. With Summer coming into full swing I am grateful he could get us in and fixed so extremely fast. I would recommend them to anyone looking for an outstanding, professional job. Thank you for a job well done!!

After a bad experience where my air conditioning unit exploded after a technician came out for a simple repair (to replace the contactor), Alex came out to look at my A/C unit free of charge. He was very knowledgeable and helpful. I have spoken with several technicians and a few came to my house in the last week or so. I felt Alex was by far the most knowledgeable and I also felt he was honest, had integrity, was someone I could trust. Thanks again Alex!

Dave and his team did a great job installing an air conditioner in one of our rentals. He did such a good job that we have hired him for another project and will be our go to guy for future HVAC projects. I will recommend him to others as well.

I had 2 issues that were beyond me, including a leak and an issue with cold water on the shower. The first was fixed very easily and at a reasonable price, and the other (due to being late in the day and the question of 'should we open up the wall') we stopped short of fixing but found out what it was and wasn't. There was very good diagnostics Dan and his assistant were both very courteous, and thorough. They explained what had to happen to make it work. They had good ideas, and were open to me not accepting a part that we'd attempted to use but later ruled out as the real issue. The price was reasonable for what was done. While I wish the problem I had could have been fixed 100% - the next steps were something I wasn't yet comfortable with. I will go back to Dan again if we decide to open up some walls to complete the fix on the shower issue.

Eric and his company, TopDawg, went above and beyond customer service and performance. Even when we had to cancel their services on the first day we scheduled, with not much notice, he was so nice and understanding and rescheduled us on a new day we requested, accommodating our schedule. The work, thus far, is flawless and the air conditioner feels wonderful! An unforeseen issue came up to where, due to our foundation, he couldn’t put an air return vent in where previously planned but quickly discovered a solution and didn't charge us for the extra work that it took. A very honest company, family-man owner, and does what he says he's going to do! Thank you so much, Eric!!

Joey and Chris are amazing! They gave me a really good which encompassed plumbing issues in two bathrooms plus the installation of a furnace and air conditioning. Every other HVAC and plumber that my husband and I tried to work with before where out of our budget. Not only did we get a really good deal from working with these guys; their quality of work is exceptional as well. I would highly recommend the Tipping Hat for your plumbing and HVAC needs.

I called this company because they were registered with the BBB and had a good rating. They asked me to choose a time, and I chose noon to 2:00. I received a text with a picture of the technician coming out which I appreciated since I'm female and was home alone. My tech called to let me know how far out he was and arrived on time. He looked at the air-conditioner and told me it just needed cleaning. He didn't try to sell me a new unit, or any kind of service I didn't need. I had him go ahead and clean the air-conditioner and the furnace and have been very happy with the results. I will call them again if and when I need any service done on my air-conditioner and furnace in the future.

I'm glad I found Notable Heating and Air who can install the wall mount range hood in our small 80's townhouse remodeled kitchen. The after installed of the wall mount range hood brightens up the entire look of the kitchen area. Mr. James is very knowledgeable, honest, reliable, and very reasonable prices. Did not charge when he had to run out for a part. Above and beyond service and we will definitely call again when we need help with other projects.

We have had a recurring problem with our air conditioner and Greg was the first person to listen to what was happening and then work to isolate and fix the issue. Once he thought he found the leak he tested the system before he recharged the unit noting that he didn’t want to waste our money or the refrigerant if the system wasn’t fixed. I really appreciated that he took on the challenge and didn’t just try to sell us a new system. The unit is only 3 years old and without fixing the leak this always seemed like a foolish option. I am so glad I found someone willing and able to fix our problem.

Michael, the owner of Goodfellas, came out and did a VERY thorough estimate for my A/C project. He actually measured my windows and doors and suggested placing a return air duct in my basement which no other estimator did. He took the time to make sure I understood everything and took the information to his office and spec'd the proper equipment for my home. Goodfellas provided me a very fair price for the equipment and labor. He showed up with an installer, Jay and also had an assistant. Very neat and clean installation and very professional at every step. I received great financing terms. They went over and above and I will gladly recommend Goodfellas to everyone looking to do a heating and cooling project. Thank you Michael!

Sears installed a new furnace/ac unit. Everyone involved, the salesman, installers, office staff were pleasant and helpful and took time to explain everything. The installers were done in half a day. I was impressed with the quality of work. I wouldn't hesitate to recommend them to anyone.

    Q & A

    Answers to commonly asked questions from the experts on Thumbtack.

    What is an HVAC system?

    The letters in HVAC stand for heating, ventilation and air conditioning. An HVAC system enables you to regulate your home or building’s internal temperature (thermal control) for comfortable living and working. You can bring heat levels down in the summer and up in the winter, keeping your home or office livable year-round. HVAC systems can also help with humidity levels and regulate indoor air quality in a home or office. There are many types of HVAC systems and technologies available.

    Many homes have a forced-air HVAC system. Both the heating and the central air conditioning units share a ductwork system where they either push in or pull out warm or cooled air. There are also heating and cooling systems that don’t require ductwork — such as ductless mini-splits — but work on the same principles of heat exchange. The national average to hire an HVAC specialist is $2,920-$3,670, with costs varying depending on the work you need done and the equipment you are installing.

    How much does it cost to get central air?

    Prices for central-air HVAC systems will vary. The national average to hire an HVAC specialist is $2,920-$3,670 but can run as high as $5,000 or even $12,000 depending on the capacity you need and other factors. Installing central air conditioning requires an entire system that works together to draw hot air out of your home. The system includes an outdoor unit, which houses the condenser and compressor, and the evaporator coils. If you don’t have an existing duct system, ductwork will need to be installed, which will affect labor and material costs. Leaking or damaged ducts will also need to be replaced.

    How many years does HVAC last?

    The number of years an HVAC system lasts depend on the type and brand of components that make up your system. The lifespan of an air conditioner averages between 15 and 20 years. The life expectancy of a tankless water heater is approximately 20 years, while a storage water heater is closer to 10-15 years. Ducts may need replacing within 10-15 years. Your equipment will have a longer life if you have regular tuneups and maintenance to keep everything in good working order. If you’re having repair problems and your HVAC system is over 10 years old, it’s a good time to consider the costs and benefits of repairing vs. replacing. Energystar.gov provides the following tips to help you decide whether to repair or replace:

    • Your HVAC system needs frequent repairs and your energy bills are increasing.
    • Your cooling or heating equipment is less efficient.
    • Rooms in your home are too hot or too cold.
    • Your heat pump or air conditioner is more than 10 years old.
      • Replacing your system with an Energy Star-certified unit could save up to 20 percent on your heating and cooling bills.
    • Your furnace or boiler is more than 15 years old.
      • You may choose to replace your system with an Energy Star-certified furnace (which is 15 percent more efficient than a conventional furnace) or an Energy Star-certified boiler (which is 5 percent more efficient).
    • Your home has humidity problems.
    • Your home has excessive dust.
      • Leaky ducts can pull particles and air from attics, crawl spaces and basements and distribute them throughout your house. Sealing your ducts may be a solution.
    • Your heating or cooling system is noisy.
      • You could have an undersized duct system or a problem with the indoor coil of your cooling equipment.
    • Your score on the Home Energy Yardstick is below five.
      • That means your home energy use is above average and you're probably paying too much for your utilities.

    How much does it cost for a new air conditioning unit?

    If you’re ready for a new air conditioning unit, it’s time to start exploring HVAC prices. The price will vary depending on the type of air conditioner you buy and its cooling capacity. Window units, which require minimal installation, are one of the most affordable options on the market. If you’re purchasing from a big-box store, you can expect to pay approximately $120-$1,000 for a window unit. Window units are appealing for their quick setup and relatively low cost, but they can use more energy over time than central air and only cool the room in which they’re installed. Portable air conditioners don’t have the cooling power of a window unit, but they do have the perk of being transportable from room to room. Expect to pay between $225 and $800 for a portable air conditioner, on average. For a whole-house air conditioning system with coils, condenser and line (not including installation or ductwork), the cost from a big-box store can range from approximately $2,000 to $4,000 or more. If you don’t have (and don’t want to put in) ducts, a ductless mini-split air conditioner is a good option, although pricey up front. Pricing can range from $650 to $4,250 per unit on average; you’ll need one unit for each room in which you want temperature control.
