"I have to give this 3 star rating based on price. 5 stars for customer service, promptness, courtesy and professionalism. The gentleman that provided me with the estimate was top notch. NO pressure, 100% honest and generally very respectful of my interaction. However, the price quoted is, without a doubt, not realistic. I searched online for furnace pricing and a very high quality and highly rated piece of equipment averaged around $2500. But my quote for a new furnace with installation was $7500! This is totally unacceptable! Furnace replacement is not rocket science. As a very handy guy, and one who has, first hand, witnessed an installation, $5000 in labor for a 4 to 5 hour job is just way more than this is worth. $1000 per hour is more than lawyers and doctors charge. And there is no flexibility on this pricing. And I don't feel that the months overhead of this company should be charged on each and every installation. Additionally, I received quotes from 3 other companies and their pricing is almost identical. Price fixing? Taking advantage of consumers? You make the call. BUYER BEWARE!"

"Service plumber arrived on site, on time and was ready to begin. He was friendly and professional. He was fully aware of the problem and what needed to be done. He acquired the necessary parts and changed them accordingly as proficient as possible. Our bathroom sink drain issue was completely resolved and ready. Thank you Eric for a great job!"

"It went very well. I believe they finished it in one day. The price was very fair and lower than the other two places we checked. The heater works spectacularly according to our tenants. The city inspector came out two days ago and gave it his seal of approval and final inspection passed! Luis the owner is an honest man. He is licensed and does great work. I gladly would refer him to anyone who needs a new heater or Air conditioner! Thanks Luis...."

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."

"The services were excellent - thorough, careful and complete. Arrived on time, and walked through the house to be certain that all vents were located. In addition, noted an issue in the basement where the vents originate and suggested a solution. Very, very pleased with this service and recommend Oren without reservation."

"I had an initial meeting with Dan when he came to inspect all of the heating duct and vents to make sure that they were not damaged and he could proceed with cleaning - very reassuring. I then received a call to schedule the cleaning. Dan is a very profession and personable young man who did an excellent job and was able to answer my questions and provide recommendations to improve the air quality in my home. Excellent first impressions and I hope to continue using this company in the future."

Boiler Repair FAQs, answered by experts

The cost of annual maintenance depends on the type of HVAC system you have. AC service typically costs an average of $200 but ranges from $100 to $550. If your system needs repairs, the price will vary significantly depending on what needs fixing. However, addressing the issues as they arise can prevent further damage to your unit and keep it operating efficiently for much longer.

To extend your HVAC system’s lifespan, it’s crucial to keep up with maintenance. This includes changing filters and thermostat batteries, keeping the outside unit clean and clear of clutter, and lubricating moving parts. Watch out for leaks, mold buildup, and blockages to ensure your unit stays in good working order. Spotting these issues early can be the difference between a simple, wallet-friendly repair and an expensive replacement.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

Regular maintenance includes annual inspections, filter changes, and checking for leaks or pressure inconsistencies to improve efficiency and longevity.

The average cost for HVAC repairs is approximately $350. However, prices can range from as low as $100 to as high as $3,000 or more, depending on the type of repair and the extent of the damage.
