We have been in business for over 35 years. Our technicians are trained experts and certified in the diagnosis, repair and installation of heating, cooling and refrigeration equipment. We take pride in our work and strive to provide the highest quality service available. Your family’s comfort and satisfaction is our number one concern.

"During a heat wave in August with temps in the 90s, our air conditioner went out. We had a technician come out on Monday morning who recommended replacement of our unit. I purchased the Enhanced Service Plan for $250 which would provide two annual maintenance services. I was told that the office would call us back with an estimate. Near the end of the day, we called and asked for an estimate and were told we would receive one in the morning. We waited until after noon on Tuesday to make a decision on which company to go with after receiving 2 other estimates. Given the heat wave and having not received an estimate from Mark IV at that time, we decided to go with a company. I emailed asking if I could receive a refund on the Enhanced Service Plan due to the untimely estimate and the company we ended up going with requiring us to use their service for the first year for warranty purposes. I never received a reply or a refund."

"This is only a limited summary. Buyer, especially seniors, BEWARE! Average product, but very poor installation quality and workmanship. BCI-BathPlanet of Indianapolis arrived an hour late without calling, and no return calls from the office, sales rep., or service manager. They damaged three areas of an adjoining wall into another room using a Sawzall. And, they left without telling me. I had to cleanup the paint and drywall debris. The next day they arrived, and I showed they the damage. They admitted they damaged the wall using the Sawzall. I withheld $500 of my payment. It should have been at least $4,000. They promised the following business day, a Monday, they would have someone call to make the repair that day, but they did not show and did not call. When I called their Customer Service, BCI-BathPlanet would not return my calls total of about 20 times. I had to stop by their office twice but they claimed "there was nothing they could do" to make the service manager return calls. They refused to have the owner call me. Our sales rep. used deceptive sales practices by claiming to be a part-owner. The office told me he was not a part owner. When I visited the office they said I could only talk with the service manager. Shower shelves fell off the walls. Caulking was very poor. After almost three months they finally attempted to make some initial repairs. So.e were satisfactory, but others were so bad I had them remove parts of the decorative trim because they said "it was the best they could do"."

"I would recommend taking your business elsewhere. We signed a contract with them in Nov '21 for work to be completed in May '22 for a large multi-house project. In Nov '22 the work was finally "completed." Throughout that time there was minimal to no communication. I would get text messages about a work crew coming to work on the install and no one would ever show up. I would get last minute text messages asking for access to inside areas they had previously claimed they didn't need access. I have had them call and inform me that a "string of panels" was not functioning, only to have the tech arrive and say everything looks fine and it's all working. I still have never been given access to the system monitoring software, despite claims that I have, so I have no way of verifying if anything is working outside of random screenshots they send of their computer monitors. On of the least professional companies I've encountered. Save yourself the headache and look elsewhere."

Energy Efficiency Auditing questions, answered by experts

Leaving vents open but closing doors in unused rooms will probably not save money on your energy bill. Closed doors prevent the natural flow of air throughout the home, which could reduce the efficiency of the overall HVAC system. They could also restrict airflow into and through the return vents, making the HVAC system less efficient.

As you look for the right soundproofing drywall for you, you’ll likely come across the Sound Transmission Class (STC) rating. This rating measures a building material’s ability to absorb sound. The higher the number, the better the material absorbs rather than reflects sound, reducing noise transmission. The STC rating for drywall doesn’t mean it’s for the panel itself—it refers to the STC rating for the entire wall system, including the soundproofing drywall.

Audits include inspecting insulation, HVAC systems, windows, and appliances to identify energy inefficiencies.

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.

Some types of electric fireplaces use more electricity than others. Models that produce 1,500 watts will have more of an effect on your heating bill than 750-watt models. 

Electric fireplaces use an average of $1.85 of electricity every eight hours. These minimal operational costs aren’t likely to make a big difference in your electric bill—unless you’re using it as a primary heating source for your home and it’s running most of the time.
