KS saved the day with prompt accurate professional service. When others wouldnâ  t respond or tried to delay service call, Lance and Rita were attentive and timely for emergency troubleshooting and repair. We will continue to call on them for any repair/ installation of our heating and air conditioning needs. Highly recommend you do the same.

It was a pleasure to work with K&S to replace my central air! They did a great job on the install, very neat, attention to detail, great price, and within the time frame we discussed. I highly recommend them!

Had a central air condenser and a gas furnace replaced. Lance and his crew showed up on time with all equipment ready to go. Job was completed in one day. The process was explained and all my questions and concerns were addressed. The cost of the job was very fair and the job was professionaly done. Highly reccommend Lance for any HVAC work.

I was impressed with the professionalism with everyone from this company including Rita, who I spoke with on the phone, and Lance, who coordinated and helped with the installation of two split AC units. I had done a lot of research about split AC units before hiring KS Mechanical... I was incredibly happy with the brand they used for this job as many of the reviews for brands available at popular home improvement stores have spotty reviews. The communication with Lance and Rita was superb. They showed up promptly at 9am on the day of the job (actually they showed up early which earns brownie points in my book). They worked efficiently and finished early. They cleaned up after themselves, which was also something I noticed and appreciated. I was so happy with the installation I signed a service with KS Mechanical to handle all my heating and cooling needs. I highly recommend this company. 5+++ stars!

Lance and his crew were fantastic from start to finish. It was a very big job, new tankless boiler install, oil tank removal and a new gas line for a pool heater. KS handled everything quickly and professionally. I would not hesitate to use them again for any future projects. Stop searching ... this is the company you call!

Lance and his crew were extremely professional and courteous. I had many questions concerning the scope of work and at NO time did I feel as if my questions were an annoyance. The crew arrived on time every day, and even took care of some ancillary issues with my utility room. The old oil tank was drained, the oil hauled away, and the unsightly tank as well. I chose KS mechanical over other vendors because from the moment Lance and I talked, he was very knowledgable and wanted my family to get our money's worth and NOT overpay. He was genuinely concerned for us and that personal connection sealed the deal for me. If anyone is in need of a professional, courteous, knowledgable and down to earth contractor, Lance and KS Mechanical are highly recommended by me.

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
