"Great experience. Very personable and knowledgeable. Mike explained everything. He made me understand that no question is a stupid one and suggested that I call if I had any doubts about any part of the installation or just questions in general. The install team was excellent too. Even after the installation, Mike suggested that I call whenever I had questions regarding the new system. I highly recommend him."

"Continental's technicians were highly experienced, professional, considerate, respectful, hard working, and neat.  They arrived on-time when scheduled.  Allied's drilling and trenching crews were excellent also.  This was a big messy job that took about a week and we are very happy with the work that they did.  The owner of Continental, Frank Jackson, sold us the system.  He provided an extensive reference list that went back at least 15 years.  He was on-site for most of the job providing hands-on supervision of his technicians.  His technicians are so experienced that he didn't have to be there to supervise them.  Rather, I believe he was there to make sure that the job was finished on time because they are so busy.  Allied had an on-site supervisor at the start of the drilling process to finalize the location of the loop bores, but their drilling crew was highly experienced and needed no supervision.
Installing geothermal is a messy job.  The vertical bores and horizontal trenching for the ground loop makes a muddy mess.  The drillers from Allied were very respectful to the property, much more than I expected.  I expected that the drilling process would make "a mess and a half" but it only made a mess!  At the end of the job the ground was re-leveled and ready for seed, which has already popped and growing grass.  As one of the drillers said "the mess only takes grass seed to fix".
The HVAC technicians from Continental left the spaces where  they worked in "broom-clean" condition.  We had to do some "deep cleaning" afterwards, but this was completely reasonable.
We expressed our concerns about the job to the technicians before they started work because we do not know much about HVAC or geothermal.  They took the time to explain what they were going to do and how they were going to do it.  They kept us fully informed about their progress and included us in the decision making process when they had more than one way of running a pipe or duct.  They made us feel really comfortable and that we were getting a top-notch job.
While the cost for the system from Continental was a little bit higher than their competitors I think we got value for money.  In addition to the reference list we received during the sale process, we also know two families that used Continental in the recent past and they are very happy with the work that was performed.
We would use Continental again and would recommend them to others.
If you go with the option to integrate your hot water heater with the geothermal system (which is supposed to reduce the cost of the hot water that you use) I would reccommend that you bite the bullet and have a preheat tank installed at additional cost.  We didn't do that and in retrospect we should have based on some further reading that we did about how to get the most bang for the buck from geothermal.  It would be easy to install the preheat tank during a new construction project.  It would be harder to install the preheat tank during a replacement project (like ours was).

"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."

"Eric came within an hour after I requested A/C service from My HomeAdvisor. He was very courteous and knowledgeable of his trade. He informed me of what the problem was, gave me options, and completed the work within reasonable time. What impressed me very much from this experience was the fact that Eric took the time to explain to me what the problem was, what caused it, and what he would do to help correct the problem, - in a way that I can understand. I had to call him back a few days after and asked him to come and check on something that I noticed since he left. He came the same day, found the problem and made recommendations. Now my A/C is working very well. He actually saved me a lot of money for what could have been a major overhaul of my A/C unit. Eric is very professional, courteous, friendly, and reliable. LOOK NO FURTHER, Eric is just the person you would call if something goes wrong with your A/C-HVAC. I highly recommend Eric and the company - Centra-Spike. Submitted 07/28/15"

"Technician came to the house and analyzed the problem. It was determined that the cost of repair was over the allowable Choice Home Warranty limit and it should be replaced. Choice Home Warranty issued their replacement cost. This cost was unacceptable and I challenged their figure. After some negotiation I was offered an increased settlement amount. I still balked at their offer but I was told to take it or repair my old microwave. I finally accepted their amount, even though it is still well below what it will cost me to replace the unit. I might add that the existing microwave has the convection feature and I want to replace with same features. The cost that I will receive also does not include any removal, disposal or installation costs. At this time I am debating whether I will continue with Choice Home Warranty or consider other options."

"That was not a happy experience.  They were very hard to reach.  They contacted me and ask me when they would come and take advantage of the deal.  I emailed them back, they didn’t respond.  I emailed them again and I emailed them again.  The third time I emailed them, I said, if I don’t hear from you within 24 hours, I’m going to cancel through Angie’s List.  Somebody called and left a message.  I called the next morning and the phone was disconnected.  I had somebody else on the phone, he said I was crazy to think the phone was disconnected because it wasn’t but it was.  Somebody called me and they arrange to come.  The finally did come.  They did what they were supposed to do on the chimney but we had an inspector come in because we are selling the house.  They missed something important that I have to fix.  They apparently didn’t do the job of doing the crown which I paid extra for.  I’m going to have to pay another chimney service to do that.  I am happy with them at all.  They said I need to replace a dent and they did ask $400 more and they supposedly fixed the crown of the chimney for another $125 but it turned out that they did not do such a good job on that.  The crown wasn’t good.  I expected them to find extra things to do but I expect them to do them right."

"My first encounter with them was my friend recommended them and it was an emergency service. They came out quick, very professional, and fixed it promptly. I liked the service so much I had a maintenance contract with them and since then he had to replace a unit and worked with me on the price and worked with me for the best deal. He is on time and updates you if he is running late."

"Hired for air duct cleaning but mold was discovered and pointed out to us.  With young children in the house, we wanted to attack this problem right away so we immediately negotiated a price.  The primary contact was a bit difficult to understand due to language differences and I'm not confident we got a good price, but we were very satisfied with the quality of the work.  They were very timely and the full service took an hour or so.  My recommendation is to check for signs for mold before you order any air duct cleaning services.

FAQs for central humidifier installation and replacement projects in Sherwood, MD

A crawl space dehumidifier is a worthwhile investment, particularly in humid climates or if you've noticed musty odors, mold growth, or wood deterioration. Though costs range from $3,000 to $9,200, this investment helps prevent structural damage that could require far more expensive repairs later. Beyond structural protection, a properly dehumidified crawl space contributes to better overall indoor air quality and may reduce allergens throughout your home. Consider having a professional assessment to determine if your specific situation warrants this investment.

Addressing crawl space moisture effectively often requires a combination of solutions. A complete approach includes encapsulation plus dehumidifier installation. For minor moisture issues, a basic dehumidifier starting at $1,500 may suffice, while severe problems in larger spaces could require systems costing up to $14,000. The most effective moisture control strategy depends on your specific conditions, making a professional assessment valuable for determining the most cost-effective approach for your situation.

For a crawl space measuring 1,500 square feet, you'll need a dehumidifier with a daily capacity of 30 to 50 pints, with unit costs ranging from $150 to $600. Your local climate and existing moisture levels may necessitate adjusting this capacity—homes in particularly humid regions might benefit from higher-capacity units. Professional installers can measure your specific humidity conditions and recommend equipment that is appropriately sized, balancing initial cost with operating efficiency for your unique situation.

Crawl space dehumidifiers add $300 to $500 to your annual electricity expenses when operating continuously. Energy-efficient models reduce this consumption by roughly 15 to 30% compared to standard units. Most contemporary dehumidifiers feature humidity sensors that automatically cycle operation based on current conditions, helping manage energy usage. Proper crawl space encapsulation significantly improves efficiency by creating a controlled environment that requires less dehumidifier runtime, thereby reducing ongoing electricity costs.
