My name is Toni. And I have been cleaning for the past 8 years. Mostly vacation homes, rentals, air b and b’s, move outs, etc. My team does a lot of cleaning for Century 21 among other realtors in our mountain area. We are reliable, have reasonable rates, pay attention to detail. And very prompt. You would not be disappointed with our service.

"Appliance Tech DR was GREAT! Timely same day arrival, knowledgable, affordable, and fixed everything including finding broken wires that were causing the ice maker not to work. He even dropped by the next day to check on the temperature of the refrigerator after service. Thats going above and beyond!"

"It was fine. There was an additional charge but I'm not surprised because I had a dryer vent that is very complicated. We negotiated and told me what they will going to take to do it. I was fine with it because I know my dryer vent. For me, to call somebody and do that specifically, it would have been more money. I feel good about it."

"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."

"Last week I had Landmark energy upgrades, do energy efficiency work at my home. The work included sealing all my duct-work in the attic as well as sealing all the spots between the living space below and blowing in additional insulation in order to bring me up to today's standards. I also had them replace all the duct work in my crawlspace and seal it as well as when they came for their initial inspection they found that my duct-work was riddled with holes and was completely uninsulated as well as being unsealed. I initially contacted Landmark after receiving notification that they were offering assorted rebates for home owners to incentivize them to do upgrades to there homes.
I was super pleased with these guys, a total of two crews worked on our home and they were both quick, professional, and explained what they would be doing in detail when they first arrived. They also did a good job cleaning up after themselves. Immediately I noticed a difference in my home after the work was finished. The HVAC system weren?t running nearly as much and the temperature in the home was absolutely more consistent.  Landmark Energy Upgrades promptly handled all the paperwork required in order for me to receive my rebates making this part of the process extremely easy. I fully recommend these guys!

Heating and Air Conditioning FAQs, answered by experts

A power outage can damage your air conditioner, just like a power surge can damage any electrical device or appliance. In most cases, your circuit breaker or built-in surge protection on your AC unit protects your AC and just needs a reset. But in other cases, it might be that your AC compressor or capacitor was blown during the power surge. You’ll need to have an HVAC professional repair or replace any AC parts. 

You should only run your dehumidifier in warmer months, such as spring and summer, to get the best performance out of your system. The air gets drier when temperatures drop in the winter months, creating less of a need for a dehumidifier. However, when to run a dehumidifier will depend on your local climate.

No. Your furnace does not run your air conditioner. Both units use the same system of ductwork to move conditioned air throughout your home, but you can have a furnace without having an air conditioner and vice versa. Furnaces are only for heating your home. You can buy a system that does both, however, like a split system or a heat pump (yes, heat pumps cool, too).

You can protect your air conditioner in the winter by turning off the power at the thermostat and performing routine HVAC maintenance in the spring. Regular maintenance, cleaning, and repair of your AC unit helps protect it and extend its life span. If you have a window AC unit, remove it from the window and store it in a dry place during the winter. Window units cannot withstand freezing temperatures. Keeping them in your window also allows cold air to seep into your home.

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.
