When the Texas heat rolls in, keeping your home cool is a priority, and our air conditioning repair services can help with that. We focus on fixing issues with central air systems, making sure your AC works efficiently and reliably. Our experienced technicians handle everything from replacing faulty parts and addressing refrigerant leaks to fixing thermostat problems. Regular maintenance checks ensure that your unit is running smoothly, so you avoid sudden breakdowns and stay comfortable even on the hottest days. Additionally, we offer tune-ups to optimize performance and extend the life of your system. Whether it’s a preventative service or a swift repair, our goal is to ensure your AC is in top shape for those scorching summer days.

Ductless mini-split air conditioners offer a lot of perks for cooling and heating individual rooms. Unlike traditional systems, they let you control the temperature room by room, so if one person likes it cooler and another likes it warmer, everyone stays happy. These units are super efficient because they don't rely on long ductwork, which can leak air and waste energy. This efficiency means you can save money on energy bills. They're also great for retrofitting older homes without ductwork or adding to new spaces like garages or home additions. Plus, installation is usually quicker and less invasive since you don't have to worry about large ducts being put in.

We focus on making homes more energy efficient through various services. We offer home energy audits to check how your house uses energy. These audits cover your HVAC systems, attic insulation, and more. Based on the results, we suggest ways to save energy like adding insulation or weather stripping. Our solar shading solutions also help reduce heat gain, which means less reliance on air conditioning. With properly insulated attics, we ensure your home stays comfortable year-round by reducing heat loss and air leaks. These services are designed to help you save on energy bills while keeping your home comfortable.

An AC system tune-up service involves checking and maintaining your air conditioning system to keep it running efficiently and help avoid surprise breakdowns. During the tune-up, technicians inspect important components like the filters, coils, and fans to ensure they're clean and working well. They also check for any worn parts that might need replacing and ensure all electrical connections are secure. These steps help improve the system's performance, extend its life, and can even save on energy bills by making sure your AC isn't working harder than it needs to. Regular tune-ups are a smart way to keep your home cool and comfortable, especially during the hot Texas summers.

We offer comprehensive maintenance services for heat pumps to keep them running efficiently year-round. Our services include regular tune-ups that focus on preventive care, which helps extend the lifespan of your system and prevents unexpected breakdowns. We make sure everything is working right, from checking the filters and coils to calibrating the thermostat, and we look for any wear and tear that might cause problems down the line. By keeping everything in top shape, we help you reduce energy costs and ensure your heat pump provides reliable heating and cooling whenever you need it.

It's been a great pleasure working with McCULLOUGH Heating and Air Conditioning. Our A/C went out on Labor Day Weekend and Jensen came over on Sunday. Of a holiday weekend! He was pleasant and even loaned us a compressor fan, which he installed, until they were able to replace the whole thing. On the day of installation, Michael and Bryc arrived early and worked swiftly until around 2. They were easy to talk to and very friendly. Jensen also came by and helped out. They did an outstanding job and I love my new A/C. Many thanks to Jensen, Michael and Bryc!!! I hope I never have to call you back, but if I do, I know you'll be right over. Thanks again!

Jensen was a absolute pleasure to work with, from day one, in regards to my home ventilation issues! Jensen is very knowledgeable and informative, in regards to heating, air conditioning and ventilation issues! As a homeowner, that knows absolutely nothing about these issues, I appreciate his patient and genuine approach, to customer service! When Jensen, and his coworker ( I apologize I did not get the other gentleman's name) showed up on time, to perform the ventilation work, it was very much appreciated! They did a extremely professional, clean and quick ventilation modification to my home! The only reason that I gave them a four-star rating, is I wished the cost was a little cheaper! However everything is more expensive these days, my wife keeps telling me, I need to get used to it! 😎😂👍
