"Steve and Josh came out today to replace the grille and some insulation in my bathroom. They both knew exactly how to go about dealing with the odd size and dimensions of the grille and the opening and also how to go about making sure that the mildew would not reoccur in this setting. They worked together well, were professional, knew their stuff, cleaned up after themselves and were friendly to work with. I'm so glad they came out and got my situation sorted out. I have used Aire Serv in the past and will definitely use them again. Thanks guys."

"Ronnie was awesome. They communicated multiple times about time and date (reminders leading up to the day) and when I showed up he was already complete with the drone footage and doing his inspection space by space. He was thoroughly knowledgeable and very kind and personable. He eased a lot of concerns and then sent over a 13 page report with photos and directions. It was amazing and totally worth the money for peace of mind Amin this whole process. I will be using their services a few more times for this and Ronnie laid out the next phase and who would be doing what. Overall, it was really great. Highly recommend!"

"As always, the team at All Star A/C & Heating Services here in Houston came through for us. Air went out in the downstairs unit at my kids home. It turned out to be a capacitor and the fix was only $269! We have been so happy with the honest and fabulous service that we’ve had with these guys for a decade now that we would never even consider calling someone else. We had been ripped off by other companies in the past who replaced entire units that were only a few years old rather than servicing just what was needed. All Star was founded by a couple of guys who got tired of working for dishonest companies that encouraged them to replace unnecessarily, and just wanted to do the right thing in their lives and work. Thanks again for being decent and honest. You’re the best! For anyone needing AC/heating services, I recommend these guys wholeheartedly. On a 10 point scale, they’re a 10+"

"I would use this company again and again. They were responsive, punctual, and SO respectful of our home! One of our AC units was dying but limping along, and they came out and gave me a realistic idea of what it would take to fix it and what that might mean overall. We opted to replace it. They gave us a great deal and were patient and worked with us as my husband was in the hospital with a serious medical condition and I was scattered as I tried to schedule the work."

"I used Service Express several times throughout the years, and I cannot express how much I appreciate them. Mike and Adam, both Lead Techs, and their crew were awesome. I had several things completed: duct redesign/replacement (all of it), vent cleaning (all 16), and dryer line cleaning. Mike provided a detailed estimate before I agreed to the job. Once the job was completed days later, Mike walked me through everything that was completed. I was pleased in what I saw! The entire crew were respectful, courteous and professional. And Gilbert, the owner, is about the nicest and most respectful person I ever met! I highly recommend their services! They earned a lifetime customer!!"

Energy Efficiency Auditing questions, answered by experts

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

A home energy audit costs about $420 on average, ranging from about $100 to $2,250 or more. Cost factors include the size of your home, the type of testing, and the thoroughness of the audit. A Level 1 walk-through inspection will cost between $150 and $200 for the auditor to point out inefficiencies in your home. On the other hand, a more thorough Level 3 audit with testing and a detailed report will cost about $900.

It’s not recommended to turn off your breaker box in hopes of saving electricity. Breaker boxes were not designed to constantly be switched on and off. Therefore, turning off breakers unnecessarily can cause costly damage that outnumbers any energy savings. Only flip your breakers if absolutely necessary when troubleshooting an electrical issue.

A good SEER rating is between 15 and 20. However, if you want the best possible efficiency, look for HVAC units with a SEER rating higher than 21. Keep in mind that the SEER rating doesn’t mean that the unit will reach that efficiency all the time, but it does have the capacity to operate at that high of an efficiency level.

There are several signs that your house might have poor ventilation, including lingering odors, condensation on your windows, or mold and mildew. Your home may also feel stale and stuffy, or you might have trouble maintaining a comfortable temperature in your home. On top of that, you might develop allergy symptoms, such as sneezing, coughing, or headaches.
