"Great. They contacted me right away. It wasn't an emergency but Iti was cold, so they still came first thing on the first business day. The technician explained what he was doing and why the prior repair done by somebody else probably failed. The rate was reasonable. It's been a couple of days and it seems the furnace is working, so everything good so far."

"I always have my doubts about what I will get for $39, so went into this deal with low expectations. I have a two story house with basement. The Green Apple crew arrived on time, with a text reminder 1 hour ahead. That always helps. Make sure you know where all your vents are, and that they are accessible (move beds and furniture if they cover a vent, that gives the crew more time to do their job). Tony explained the difference between cleaning the vents, and a deep cleaning of the ductwork. After confirming that I had not had the ducts cleaned in the 20 years I have lived here with 2 dogs, Tony walked through the entire house and took photos inside the ducts. How embarrassing! It was obvious I needed the deep cleaning service (what was that lump in there? We needed to find out). Deep cleaning is more expensive, but when you see how much work it takes for Tony and his energetic assistant, Julian, to really get into and clean the ductwork, you will understand why. They worked steadily for over 2 1/2 hours, and had all the correct equipment to do a very thorough job. They even cut into and repaired the original 1929 ductwork to get at difficult spots without extra charges. Overall, a great job, and today was the first time in months I didn't wake up sneezing. If you are sensitive to chemicals or fragrances, be sure to check the disinfectant before it is used, though there is no hint of it after 24 hours, it has a strong smell when first applied. Again, you only need deep cleaning once every 5 years, so it is worth the .15 cents a day to breath easier. Thanks again to Tony and Julian for a job well done. Pay Tony, tip Julian! (The disgusting lump was a towel I had never owned. That made it worth the price right there.)"

"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."

"Jazz Heating & Air Conditioning has been amazing to work with. I sent out inquiries to several other companies on Angie's List. I had done a lot of research and knew exactly which furnace I wanted. Mirza was super responsive over messaging and was able to provide me a proposal without having to schedule an appointment for estimation! He had me take some pictures & measurements and send them over. This was such a pleasure because all the other companies wanted to send someone over, and I don't have time for that many visits. The price that Jazz gave me was very competitive, and they didn't try to upsell me to a more complex unit. The replacement turned out great. They cleaned up really nicely and was really thoughtful in giving me a tutorial of the system."

Boiler Repair questions, answered by experts

DIY is not recommended due to safety risks and technical expertise required. Hire licensed professionals.

A poorly maintained boiler can lead to serious issues like deadly carbon monoxide poisoning, so schedule regular maintenance services. Of course, it’s also a good idea to check your carbon monoxide detectors in your home to make sure they’re working properly. Moreover, when you forget to maintain your boiler, small problems can lead to something much more serious, which will cost you more money in the long run. Repairs average around $400, while a full replacement can total over $6,000.

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.

Yes, it is generally safe and effective to turn off radiators in unused rooms to save money on heating costs. This practice is especially beneficial with older heating systems. However, you should avoid cranking up the thermostats on the remaining radiators to compensate, as this can lead to higher heating bills and increased wear and tear on your system. While some HVAC specialists argue that modern, efficient boilers are designed to heat the entire home and work best when all radiators are on, turning off radiators in unused spaces still reduces the total amount of hot water your system needs to produce.

Properly maintained stucco can enhance insulation, reducing energy loss.
