"Communication was excellent and was able to replace my lighting fixture the same day. It seemed pricey-$300! They did take away my old fixture and box of the new one. I did not shop around to compare prices because they were so prompt and able to get the job done right away!"

"Dillon was a great guy and worked fast and efficient. My house is 50 plus years old and the duct work had never been cleaned. Post the work, the house even smelled better. I am in the middle of a complete remodel and living in the house. I had all 11 vent grilles removed -(saved Dillon a pile of time not having to remove and re-install) and I would have thought a discount would have been in order."

"This company raises the bar for customer service! I hired them to clean my ductwork and my dryer vent. Dillon explained everything that was going to happen - so I felt that I knew what the plan was. He is a wonderful ambassador for the company! Both he and Steven were hard workers who efficiently got their jobs done. Every time they came into the house, they removed their shoes (even though I told them they didn t need to). Very nice! The prices were very reasonable and the before and after photos showed me the quality of their work. And the scheduling process was easy, with a reminder call the day before and a call when the technicians were on the way. I m very pleased with this crew and this company."

"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."

Heating and Air Conditioning FAQs, answered by experts

Air filters with a high MERV rating, 11 or above, shouldn't cause airflow problems in most residential systems. However, the airflow can be restricted in some HVAC systems if they aren't designed for high MERV ratings. If in doubt, a local duct installer should inspect your ductwork so that you know what your system can handle.

The cost to replace an AC unit averages around $5,900, with a typical range between $3,900 and $8,020. The final price depends on several factors, including the type and size of the air conditioner, its efficiency rating, your geographic region, and labor costs for installation. Smaller units like portable and window ACs are much less expensive, costing between $90 and $550, compared to central or ductless systems. If your current unit is less than 10 years old, repairing it may be more cost-effective than a full replacement.

Don’t run your AC with a wet filter. It can cause your AC to work too hard, which will run up your utility bill and cause extra wear and tear on the system. You could also spread moisture and mold throughout your house. Turn off the AC, remove the wet filter, and check for cracks or clogs. Fix the problem (with a pro’s help, if you need it), and put a dry filter in place before you turn the system back on.

Swamp coolers cost approximately 50 percent less to install than central air conditioners and cost less to run. Operation costs depend on the size of the unit and home, your climate, utility rates in your area, and the system’s efficiency. Swamp coolers use 15 to 35 percent less power than air conditioners.

To keep a window air conditioner in good working order, you should clean the filter regularly, inspect the seals, and store the unit properly during the off-season.
