"Someone came out the day before to see where the furnace was going to be installed. He suggested we go with a slightly larger unit for the size of our house, but we opted to go with the unit that was included in the deal.
Two men came out and installed the A/C and furnace. They told us they would be done with everything in about 4 hours, and kept pretty close to that. The furnace and A/C are both working perfectly so far.
We were mostly very happy with the company and the men who installed our units. There were only a couple minor annoyances. Our old furnace was incredibly rusty inside, and when they removed it from the house, they left a trail of rust and dirt from the basement to the front yard (including through our living room). They did not offer to clean it up, but left it for us to deal with. They also broke a light bulb in the basement and didn't get all the pieces cleaned up.

"They come on time and took shoes off as I requested. Two guy--Nick and Nick. Nick one used a vacuum clean all the ducts, only missed one, first floor and second floor. Nick two explain to me what a whole set of job will be --clean the duct, but one for one set in/out and mine has two small branches, he called 3 Mains/feeders. Then he'll need make small openings on the main/feeder ducts in order to use brush clean the inner surface. He also said there are animal hairs inside, need to be clean, mold need to be sanitized and I request a cut for easy insert the filter. It took them from 12 pm to 2 pm finish all. They also spread some protection for the rusted cover, due to the moisture. Nick is very patient with my questions. I also mentioned the dryer vent on the coupon, asked they to vacuum the basement near their work area since it's new carpet. They did it.
After all, I gave the coupon, which is $89 and check with $948. Now I realize I'm overpaid at least $89, if not more.

In one word, this is a really bad deal!! I end up pay more than other companies regular price and I'm not 100% trust if all of the "job" they listed are really needed."

"We've got American Home Shield. So that kinda varies but united air temp has done some work for us. Probably a couple years ago, I think so. I think its two years ago. They did work on our air conditioning. Well you know with American Home Shield you only pay $75.00. You sign up for a year , its like something you subscribe to.  You call and contact American Home Shield and they have somebody contact you whose in line with their services and agrees to work with them. You pay $75.00 and if its not done correctly for each visit but if they come back twice you don't pay again. Its like 400 and something a year. Its fabulous, its fabulous. If you need plumbing , H VAC, lighting, its amazing. Its worth every dime. And if they can't fix it they replace it at no charge unless you want to upgrade There are some different companies but even when we refinanced our house they had us, no we bought another house in Winchester for our son. And they made us have it in with our policy and they use American Home shield. its fabulous and you don't have to do the searching or anything, If you aren't happy you just tell American Home shield. One time United Air Temp tried to talk us into , they did some plumbing work too, and they were going try to talk us into replacing it with a cheap model. That isn't American Home Shield policy its with the same thing or you can pay to upgrade. Pay the balance of an upgrade. We use it all the time. When my son has issues with his house I tell him just call American Home Shield. They guarantee they will be out within 72 hrs but its usually within 24 hours. We contacted them last week about my son's air conditioning. They came out right away, they had to order something. They had to come back out and they did last Wednesday and they fixed it."

"Thank you West Heating and Cooling! We had a big problem on our hands - our 3 systems (heating, cooling and hot water) went out at the same time! The HVAC and water heating systems were all one unit and it was a true miracle that West Heating and Cooling could help us so quickly. We called about 5-8 other companies - but Brian (owner) came to the rescue. Brian has so many years of experience that he knew very quickly what needed to be done. He went above and beyond to get us our water and heat as quickly as possible! I will say that he is the best professional in-home expert we have ever had. Every person that we dealt with at this company was friendly, professional and knowledgeable. Thank you so much to this great team of people! I highly recommend them!"

"I was very pleased with the sales person and also with the installers. They were helpful in explaining how all the systems worked. When my system was installed there was a valve that did not work and every one did a great job to get the replacement part as soon as possible."

FAQs for central humidifier installation and replacement projects in Saint Robert, MO

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.
