Join the BK Mechanical Family!

Preventive maintenance agreements (PMAs) are agreements between you and BK Mechanical Services to provide you with scheduled inspections and maintenance of your heating, ventilation, and air conditioning (HVAC) system.

It is our hope that you will come to appreciate this agreement as a “Valuable Partnership” for you and our company, designed to save you money and to prevent costly damage to your system, because something unforseen was not discovered…until it is too late!

Residential PMAs are generally scheduled semi-annually to maintain peak efficiency, prevent utility overpayment, and avert system failures through predictive maintenance that can help extend the life of your HVAC system. Sometimes PMAs are also referred to as “planned maintenance agreements,” “start and checks,” or “preventative service agreements.” PMAs usually consist of fall and spring scheduled sessions for a service technician to go through your entire HVAC system preparing it for the upcoming season in a proactive approach before system failure and prior to overpaying your utility company.

BK Mechanical Services Is Simply the Best

BK truly went above and beyond for our family when a local company failed us. After dealing with a frustrating situation, BK stepped in, got us on the schedule the very same day, and quickly corrected multiple issues that were preventing us from fully enjoying our dream home.

From the very first phone call, we knew we were in good hands. Tosh answered with genuine care, compassion, and concern, immediately reassuring me that everything would be taken care of; and she was absolutely right. Misty in scheduling listened carefully to every concern and made sure BK was the right solution for us.

Anyone who lives in Rayburn Country knows the water here is less than exceptional. BK introduced us to the Halo water system, and it has been a complete game changer. We now have crystal-clear, safe water; something everyone deserves.

Waylon and Michael are two of the most experienced, professional, and friendly plumbers I have ever encountered. From the warm greeting at the door, to the quality of their work, to taking the time to ask if we had any questions before they left; every detail mattered. They even left the work area cleaner than when they arrived.

Dallas is our primary home, but here in Rayburn Country there is only one plumbing company we will ever use; and that is BK. I recommend them to anyone and everyone who needs a plumber in this area.

Thank you, BK, for helping us close out 2025 on such a positive and reassuring note. You’ve earned customers for life.

There was contact from the main office asking that they come to do a check up on the new system. It was scheduled for a Technician to come out. Another call to ensure technician was on his way the day set. Technician came out. Changed filter, check unit all over even offed expertise on keeping unit clean from moisture build up and dust. The area was left clean and in order. Very nice personality, knowledgeable of his equipment and shared how to order filters. Service was very good. Thank you.

Had a new hot water heater installed. They had to cut out a cabinet it was in and you would never know it by the clean up job they did. Mike was so courteous and kind and would definitely have them back again for service. I would recommend BK Mechanical for sure, you will be satisfied.

Misty Shakeel was quickly able to schedule an appointment for an estimate to replace a leaky kitchen faucet, water filtration unit, bathroom faucet and install a new garbage disposal. Ryan came the next day to do the estimate. He was so nice, friendly and knowledgeable. He looked at everything that needed to be done and then emailed me a very reasonable quote. Again, Misty was quickly able to schedule a technician to do the repairs. The technician, Mike Coil, arrived and promptly began the work. He was so nice and proficient! He completed everything on the list efficiently, double checked for leaks and cleaned up afterwards. I was very pleased with the job he did! Unfortunately, since our house is almost 50 years old, the spigot for the filtered water on our kitchen sink started dripping 2 days later. It was the only thing not replaced with everything else! Once again, I called Misty and she got me scheduled quickly. Mike came out again and quickly and efficiently replaced the Spigot. We have used BK Mechanical several times over the years for toilet and shower issues and they have always been great! Quality work, great technicians and reasonable prices! They will always be my go-to guys!

The person answering the phone was polite and made arrangements for ASAP, which was early the next morning and when the repair man was going to be a little later she called and explained. He came did excellent work and gave me an estimate for my other issues. I will be doing the repairs in the very near future. I will continue to use and share with friends and family
Got my repairs done!
We found an additional problem and Ryan and his crew did the repairs that we were unaware of with no additional charges. It was fairly quick and the men were just outstanding.
I will definitely call them for anything else I need repaired!

We just purchased a new home at the beginning of 2024 and from the start had issues with the AC System that was installed with a different company. I reached out to BK mechanical and they were knowledgeable on diagnosing the current system on our home. Mike was really great and very patient with us throughout this process of replacing our AC system. Our previous system was oversized, and Mike immediately was able to determine that by performing a manual J report on our home. The team that came out to remove the existing AC system, and then install the current system were very courteous and they always made sure they cleaned up their mess. We now have the proper size AC for our home and they also installed a mini split in our bonus room upstairs and I can’t even begin to explain how much of a difference this is made in our home. My husband and I highly recommend BK mechanical services and we will never call anyone else.

I have had BK Mechanical come to my house for jobs as simple faucet and toilet Installs, but they handled so much more. some very large remodels were done by adding a gas stove line, then tearing out foundation to move bathroom fixtures and adding plumbing for my new kitchen island sink.

Each time they are professional, dependable and stick to the timeline. I had a pleasant experience from the ladies that answer the phone, to the project manager and to my front door with the certified professionals that completed the job.

Thank you BK for helping me remodel my home!

Preventative Maintenance

Preventive Maintenance = $avings!

Take care of your HVAC system, and it will take care of you.

Preventive maintenance agreements (PMAs) are agreements between you and your Air Conditioning Contractors of America (ACCA) quality contractor for scheduled inspections and maintenance of your heating, ventilation, and air conditioning (HVAC) system.

PMAs are generally scheduled for the spring and fall to maintain peak efficiency, help keep utility bills lower, extend the life of your HVAC system, and avert failures. Sometimes PMAs are referred to as “planned maintenance agreements,” “start and checks,” or “preventive service agreements.” Most agreements offered by ACCA contractors cover an inspection of the entire HVAC system and routine maintenance (such as replacing or cleaning filters).

Improved Energy Consumption

The HVAC system is most likely the single biggest use of energy in your home. In commercial applications where refrigeration is applied (combined with the HVAC systems), huge amounts of energy are used in the building. In fact, over a third of the energy used in the United States is used to heat and cool buildings.

According to the Consortium for Energy Efficiency (CEE), up to 50% more energy can be saved with proper installation, sizing, and maintenance of commercial central air conditioning and heat pumps. Although the CEE study did not measure residential systems, a compelling case can be made that proper maintenance can save homeowners up to 50% as well.

Out of Sight, NOT Out of Mind

The cliché “out of sight, out of mind” is often the reason for neglected maintenance on your HVAC system. HVAC systems are usually installed where they aren’t seen, such as in a section of the basement, a closet, on rooftops, or in mechanical rooms, making them easy to ignore. The systems are simply taken for granted, until they fail. Decreased efficiency, utility overpayment, discomfort, loss of productivity, premature replacement, and higher repair costs are the result.

Getting your HVAC system checked twice annually is just as important as changing the oil in your car every 3,000 miles!

Spring Visit

preparation for summer season
Clean inside coil condensate pans, condensate traps, and condensate lines to prevent obstructions.

Clean outside coil and straighten fins for efficient operation.

Check refrigerant levels. (According to many equipment manufacturers, a 10% refrigerant loss will result in a 20% decrease in system efficiency!)

Fall Service

preparation for Winter season
Clean the burner assembly.

Remove soot from fireside of burner.

Clean and check operation of humidifier.

Inspect the heat exchanger for cracks.

Adjust air-to-fuel ratio of burner and perform combustion analysis.

What should you expect your ACCA member service technician to do during a PMA visit?

  • Check system functions, safety controls, and adjust the operating sequence where appropriate.
  • Inspect electrical components and connections and repair/replace or tighten as required.
  • Ensure proper airflow and change dirty air filters.
  • Inspect pumps, lubricate and check flow rates where appropriate.
  • Clean and lubricate motors as required.
  • Examine belts, adjust and align as required.
    Inspect, clean and balance blowers as required.

Avoid breakdowns with proactive maintenance!
