HVAC Repair, Installation & Maintenance FAQs

ACS Absolute Comfort is unique because we combine quick response times, honest, open service, and NATE-certified knowledge. We offer HVAC solutions for both homes and businesses, give 24/7 emergency assistance, and take care of all from installations to maintenance and repairs. We are among Houston’s most reputable HVAC providers because of our priority on long-term dependability, client education, and superior workmanship.
How quickly can ACS Absolute Comfort respond to an HVAC emergency?
ACS Absolute Comfort frequently responds to your call within hours and offers quick emergency HVAC service. Our staff is accessible 24/7, including on weekends, holidays, and at night. When technicians arrive with standard replacement parts, they can rapidly restore your comfort and do numerous emergency repairs on the spot.
Are ACS technicians trained to work with all HVAC brands and models?
Yes. All major HVAC models and brands can be diagnosed, repaired, and maintained by our NATE-certified experts. Whether you’ve got a system that is older or a high-efficiency new unit, we have the skills and tools to deal with it. Because of this, we are a trustworthy option for large commercial buildings, households, and enterprises with multiple brands.
Does ACS Absolute Comfort offer maintenance membership plans?
Absolutely. To maintain your HVAC system operating well throughout the year, we provide maintenance membership options. Seasonal tune-ups, priority planning, subsidized repairs, and longer equipment life benefits are common features of plans. Frequent maintenance lowers long-term energy expenses, enhances indoor air quality, and decreases breakdowns.
What are the signs my HVAC system needs to be replaced rather than repaired?
Your HVAC system may need to be replaced rather than repaired if it shows symptoms like:
• Frequent malfunctions or growing repair expenses
• Unpredictable increases in energy bills and varied temperatures throughout your house
• Your unit is more than ten or fifteen years old.
• Strong smells, loud noises, or inadequate ventilation
• Extreme weather makes it difficult for your system to function.
A replacement is frequently the more economical long-term answer if you’re dealing with two or more of these issues.
What is the average time it takes for installing a new HVAC system?
Depending on the type of system, the layout of the house, and any necessary ductwork adjustments, most standard HVAC installations take four to eight hours. Commercial installations, multi-zone setups, and high-efficiency units are examples of more complicated systems that could take up to a full day. Before work starts, your technician will give you a thorough schedule.
How can I reduce my electrical bills without changing my HVAC system?
You may drastically cut your energy expenses by:
- Making a seasonal HVAC maintenance schedule
- Every one to three months, replace the air filters.
- Fixing air leaks around windows, doors, and ductwork
- Using a smart or programmable thermostat
- Maintaining free and unhindered vents
- Increasing shade and insulation in homes
- Upgrading or cleaning air ducts
These easy actions increase productivity, lessen system stress, and maintain year-round comfort in your house.

Thanks for all you do! chauduonguyen Excellent service and responsive. jenny dyo We love ACS Absolute Comfort Heating and Cooling their technicians are very professional and experienced. Sadik Ahmed David is very professional and knowledgeable. He's honest man omar e I have to write a new review for ACS to describe another experience with the company. Today, the A/C was running but I noticed that it was warm inside the house. I checked the thermostat and it was 79 F despite having a setting of 75 F. I checked after 30 minutes and saw that the temperature was rising - it was now 80 F. I sent a text message to ACS ( Mike Pham ) about the issue. I waited a bit for a reply because it was a hot and humid day in Houston and technicians are very busy. After waiting for sometime, I received a call from Mike saying that he's sending a technician shortly. Within 30 minutes, the technician was at the door. He went to the backyard, inspected the A/C unit and performed the work. I had cool air back in the house. The ACS company, Mike Phan, the team have all been very professional, transparent and wonderful to work with. I only have high praises for this company and its staff. I don't want to experience any more A/C or heating issues. However, in case I have any problems in the future, Mike is already aware that I'll be calling him again... and probably many times... I appreciate the quick and professional service that ACS has given me over the years. Thank you very much, Mike and the ACS team. Broderick Davis Thanks to Mike, he came out same day for service call and returned early the next morning with part to get my AC back up and running. He was very polite and professional also quick service. Thanks once again Mike. Dayan Gonzalez ACS Absolute Comfort Heating has been a reliable choice for HVAC, providing honest and efficient work at reasonable. Their team members, Mike and David, stand out for their great service. I have been a loyal customer for years and have always been satisfied with their work. Highly recommend ACS Absolute Comfort Heating for all your heating and cooling needs.
