"We were very happy with Bama Air Systems. They came out for an estimate on a Mini-Split in a timely manner, and had a quick turn-around time for installation. Their service professionals, Austin, Zach and JC, were on time, friendly and courteous, and very efficient. The installation took less than a day, and they cleaned up the construction debris thoroughly. We would definitely recommend them for your HVAC needs."

"This was the second system we purchased. The first was a replacement heat pump for our upstairs system. This one was an air conditioner and gas pack heating for the main residence. We purchased this through their rebate offer via Costco. We really wanted this to be a no problems sale. We paid in cash (check) the day before it was installed. The basic unit seems to work correctly and reliably so far. The inside has been comfortable since it was installed. That’s the good side of the story. The unit upstairs was installed with a programmable thermostat - Which I did not particularly want. That programmable thermostat is awkward to use - And I am a degreed electronic engineer! I eventually replaced it with a simple non-programmable thermostat. When I got the quote on the recent main unit replacement, I insisted on keeping my simple to use Honeywell Electronic heating and cooling thermostat. We are retired and one of us is usually home so there is zero reason to use a programmable thermostat and frankly the Lennox programmable one is a misery to use. When the installers arrived I placed the installation manual for the existing Honeywell thermostat on the thermostat itself - Impossible to miss! The main unit was installed correctly and seems to work well. But the installer had difficulty hooking up the Honeywell thermostat due to wiring problems eventually found under the house in the thermostat wiring. It was a warm day on installation day and the heating settings were only briefly tested. Then the AC settings were tested and the installer was very quickly out the door. A week or so later it got cool and I switched to heating. In heat mode the circulation fan would not run unless the heat was actually heating despite the thermostat being set to fan “ON”. I am an electronic engineer and I suspected there was an error in the hookup of the thermostat. Turns out I was correct - The installer had set the internal thermostat switch to “heat pump” instead of AC with gas heating he had installed. Furthermore he had hooked up one thermostat wire to the wrong terminal. He has to go out of his way to make these mistakes instead of leaving the thermostat wiring and internal switch setting as it had been. I corrected these two errors and then the system ran correctly. Anyone can make a mistake, but it takes something “special” to be so sloppy in testing the installation not to notice it wasn’t acting correctly! Well I thought the only problem I had with Annette Hale Indoor Comfort Air was the sloppy installer. Just this morning the sales person called me to ask if we had paid for the unit from several weeks ago! The same sales person who picked up the check the day before - Which had cleared the bank some time ago. I may not be have been very polite with this person - It seems their accounting people are just as sloppy as their installer. Eventually I was called back and he apologized that they had been paid, they just somehow credited it wrong. I would never again use this installer. They screwed up part of the installation and then may have tried to collect twice for the same work! Sloppy, very sloppy! The Lennox equipment itself except for the miserable programmable Lennox thermostat works well and seems of good quality."

"We started out with a simple request to replace some siding and ended up using Barry and his team for everything, and let me tell you, they have been AWESOME throughout this entire process! He and his team have repeatedly gone out of their way, every step of the way, to make sure that we're not only getting what we asked for, but also to ensure that the work was being done correctly, quickly, and at a reasonable price. They didn't just patch things up outside, they've completely restored this home. It's even better now than it was originally! It's simply amazing to see the absolute transformation this house has gone through in such a short amount of time and we could not be more satisfied with the job they've done! I would highly recommend Barry and his team for any project you have - literally, ANY project - these guys can do it all! Just give him a call and get that free estimate, you won't be disappointed. Also, everyone on the team was great, but I need to give a special shoutout to Michael - he was out there through the entire project and had some amazing recommendations that really took the remodeling phase to the next level! Just another reason you can't go wrong choosing Homeworx."

Boiler Repair questions, answered by experts

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

Regular inspections, cleaning, and checking of exhaust systems maintain safe operation, ensuring efficiency.

DIY troubleshooting is possible for minor issues like bleeding radiators or resetting the system, but professionals should handle complex repairs to ensure safety and efficiency.

After you receive your audit and report, review the findings and determine which of the prescribed changes you want to make to improve your home’s energy efficiency. Start by contacting the type of professionals recommended by the auditor who can help you remedy the issues discovered during the audit. Prioritize the projects by urgency, importance, and budget. Then, gather estimates from several professionals, remembering to verify any necessary licensing and experience information.

HVAC quotes may be negotiable. It’s important to be upfront about what you need, your budget, and your expectations. However, your contractor must suggest repairs or the system they think is best for you, and those things may not be negotiable. So, when can you negotiate an HVAC quote? When installing a new system, you may not need to replace ductwork or install specialty items such as whole-home air purifiers. If your contractor is bidding on those items or others you don’t need or want, ask them for a quote on only the equipment and services you need.
