HVAC Repair Services
Our comprehensive HVAC repair services address furnace and air conditioning system issues with precision and efficiency. Our NATE-certified technicians diagnose problems ranging from minor component failures to complex system malfunctions. We utilize state-of-the-art diagnostic tools and maintain an extensive inventory of genuine manufacturer parts to ensure quick, lasting repairs that restore comfort while maintaining energy efficiency. With same-day service available, we minimize downtime during extreme weather conditions.
Duct Cleaning
Professional duct cleaning services improve indoor air quality by removing accumulated dust, allergens, and contaminants from HVAC ductwork. Our truck-mounted vacuum systems with rotating brushes extract debris from supply and return ducts without damaging system components. This process enhances airflow efficiency, reduces respiratory irritants, and extends equipment lifespan. We follow NADCA standards and provide visual inspections before and after cleaning to demonstrate results.
Indoor Air Quality Solutions
Comprehensive IAQ solutions including HEPA filtration, UV germicidal lights, and whole-home humidification systems combat air pollutants and allergens. Our specialists conduct air quality assessments to identify specific contaminants affecting your home. Custom installations address moisture control, chemical off-gassing, and microbial growth. These systems particularly benefit allergy sufferers and those with respiratory conditions by maintaining optimal humidity and removing airborne particulates down to 0.3 microns in size.
Heat Pump Services
We provide complete heat pump solutions including installation, repair, and maintenance across residential and light commercial applications. Our technicians specialize in both traditional and ductless mini-split heat pump systems, optimizing performance for Indiana's climate. Services include refrigerant charge verification, coil cleaning, and defrost cycle calibration. We also offer heat pump conversion packages to help homeowners transition from traditional HVAC systems while qualifying for energy efficiency rebates.
Furnace Replacement
Our furnace replacement program features high-efficiency models with AFUE ratings up to 97%. We conduct detailed load calculations to ensure proper system sizing for optimal performance. Certified installers follow manufacturer specifications for venting, combustion air requirements, and electrical connections. New installations include smart thermostat integration and comprehensive efficiency testing. Customers receive lifetime equipment registration and priority service benefits with qualifying system purchases.

I have had so many bad experiences with HVAC companies over the years. I am so glad that I found Rearick's. Honest, punctual and reasonably priced is a combination you don't often see. I highly recommend them. Service: Repair HVAC

I wish I had read reviews prior to having them service our central ac unit. Now only half of our house is cool. And price was too high. I'm also waiting for a response. Seems to me checking all the vents to make sure I was receiving cool air would be part of the inspection.

We have purchased both a 92% efficient furnace (in 2005) and and an AC (in 2012) from Rearick's and their service and follow-up has been great. They also had the best price for each. I would recommend them. They also serviced a furnace in a rental recently even though it was not one they installed.

This place is pathetic if emploees themselves post reviews about the company. "Best place to work in the world." Really? Being new in the area just hired them to repair our furnace. Rip off prices, rude customer service and the tech messed up our furnace system where only half of the house is being heated. Paid almost $500 for ignition box replacement and have only half of the house heated. We would never hire them again nor would recommend to anyone. Called and complained, no response yet.

This llace is pathetic if emploees post reviews themselves. "Best place to work in the world!" REALLY? Rip off, rude customer service and tech, do not stand behind thrir work. My advice to the person who gave them one star for not showing up- be glad! We paid almost half of a thousand dollars for 10 minutes work and have only half of the house heated after their service. Horrible business, stay away.

Needed some work done on my furnace in my Merrillville home. I called 3 days ago and the person said someone would call me back. Still waiting.
