"Fast response and the technician found the problem within 10 minutes. They also checked the unit for other possible problems and found everything was okay. They took photos of the problem and showed explained the situation and how they can prevent the problem in the future. Their office mad a follow up call the next day to make sure we were satisfied. They know customer service and keep their technicians updated all the time. Thank you AlyAins Heating and AC, Inc, doing business as Aire Serv of Liberty.

"I contacted Duggins, in addition to numerous other heating and cooling companies, to obtain an estimate on replacing my entire HVAC duct system. Having had some issues with it over recent years and doing quite a bit of research, we knew we were ready for better insulated flex duct, better air quality, and a more comfortably conditioned second story in our Cape Cod home.
David Mitchell was my service consultant. He was very patient and thoughtful when responding to any of my questions, as well as providing thorough responses. He listened to the issues that I told him we wanted to address, and very adequately proposed possible solutions. He did not try to 'sell' me on anything I wasn't conveying I wanted, and offered his professional opinion on how to achieve my desired outcome. Once provided with the final proposal, I was very pleased. It came in quite a lot lower than the #2 company I was also considering.
My only additional consideration was to be assured that there would be no possibility of any sort of contaminant(s) left within my duct system / heating and cooling unit. I had done some research on this issue, and David was more then willing to look over some internet links I sent to him regarding EPA approved sanitation products, etc. To address these concerns, Duggins sub-contracted with The Duct Doctor to come on site to sanitize the one return box they were unable to replace, in addition to the blower, coil, etc. I was not only very pleased that they made the effort to do this, which ultimately won them my business, but I was also very impressed with Jim Gehling, of Duct Doctor of the Triad.
The crew of three technicians that completed my job were timely, polite, and efficient. They were thorough, cleaned up after themselves, and went to fairly great lengths to assure that my flex duct that ran through a chase to the second-story was completely removed and replaced. Instead of cutting a whole into my wall, one of them was very resourceful and created a sort of internal ladder to access the chase, then climbing up inside to cut a whole slightly larger through the floor above so that they could pull the new flex duct down into the crawl space. This saved me the additional work of replacing / repairing drywall!
I was VERY please with the estimate, the crew, and the work that was completed. I will likely be switching my seasonal inspection contract over to them. I would not hesitate to recommend Duggins Heating and Cooling to anyone. . ."

"Excellence in HVAC and the human spirit. That is truly hard to find in today's corrupt world. Christopher is an exceptional young man, and exuded every good quality of an upright character. I didn't know how to reach Miller's, so I left an AI automatic generated message, emailed Austin, and waited for a call back on the weekend mind you! Austin saw his email, and staff saw the AI, and Austin fielded the call to Christopher who called me and promptly came out. I can't say enough about the heart of this business. They follow this biblical teaching in the Bible: Philippians 2:3,4,5 Let nothing be done through selfish ambition or conceit, but in lowliness of mind let each esteem others better than himself. Let each of you look out not only for his own interests, but also for the interests of others. Let this mind be in you which was also in Christ Jesus. Need I say more? May God bless your business for the kindness and generosity you have shown."

"William brought his best HVAC Techs to our home. He listened to our description of the problem. He and the Tech Bob accessed our attic to directly examine the furnace in operation. Thru it they found the problem source. They explained our options. They ordered the parts, returned ASAP. Installed the new parts, adjusted them appropriately. We are now comfortable, and happy. Go Shamrock! We like their wprkmanshop, thanks guys."

Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.
While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.
The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.
Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
