Replacement HVAC Advice from Gorman to You: Top 5 FAQs Before You Upgrade Your System

Should you replace or repair your HVAC system? Many homeowners and business owners are overwhelmed by this decision. Although it’s always best to let your HVAC professional help you make the ultimate decision, we like our customers and readers to be well-educated. Get some hand-picked replacement HVAC advice with these top five FAQs we’ve compiled, based on typical client questions.

1. What size system do I need?

The size and configuration of your home or business will determine the HVAC unit capacity you need. If your unit is too big, it won’t run as frequently as it should and will provide poor temperature and humidity control. Too small, and it will struggle to power heat and air conditioning to all the rooms. In the HVAC industry, we use the standard Manual J load calculation that considers climate, size, shape, and orientation of your home or building, as well as square footage. A contractor or technician must calculate this number to ensure proper HVAC installation.

2. Can I keep my current ductwork?

It depends. Because duct systems make or break how well air is distributed through a home or building, we’ll take a good look at your ductwork before determining this answer. Many duct systems are too small, kinked, or blocked, lowering the efficiency of your HVAC system. If we find an issue with your ductwork beyond simple repairs or an upgrade, we will include whatever work you need (replacement or major repairs) in your estimate.

3. What type of HVAC unit do I need?

Although a qualified HVAC technician can give you the best answer, you usually have four options for North Texas: split-air, packaged, variable-speed, and heat pump. Split-air includes two units (one outside your home and one inside) that communicate via coolant lines. A packaged system sits both units one cabinet, installed outside. Variable-speed furnaces run based on what’s needed for the season or time of day, increasing energy efficiency. Finally, heat pumps, a popular choice in our region, are basically air conditioners that work in reverse to heat your home during the winter.

4. Do you recommend a special thermostat?

Yes, we are big fans of smart thermostats. With a thermostat that you can adjust to within a fraction of the temperature you want, you can dramatically save on annual energy costs. Many newer HVAC systems come with programmable, smart thermostats that you can operate remotely using an app on your phone.

5. When is the best time to replace my HVAC system?

Although you can’t always control when an emergency might force you to completely replace your HVAC unit, there are peak times for replacements and upgrades. We tend to suggest replacing during the summer when it’s easier to get your system prepared for winter for maximum efficiency and energy savings. Milder months are sometimes a slower time for HVAC companies, so you also may find more specials on installations.

Gorman Mechanical installed a brand new cooling and heating system in my home. The replacement unit was larger and more energy-efficient. Our house has never been cooler and our energy bill even went down…. I highly recommend them and their services.

I had an issue with my A/C unit not cooling properly. The technician, Stacy, arrived during the time frame I was given, and I received a phone call about 30 minutes prior to his arrival, letting me know he was on his way. He was very professional and conscientious in figuring out and explaining the issue to me. He work was complete in a little over an hour and my house is cool once again! I will definitely refer Gorman Mechanical to others.

- S.M.

A Gorman technician came over to set us up with a new A/C unit and he did a phenomenal job. He was very up front with any cost and got our install scheduled in one day. He did a great job at getting me the unit needed without running the price through the roof.

I met with Gorman Mechanical’s Sales Manager. When he came out I had a bad taste in my mouth due to some misrepresentations made by another company that happened to be A rated on Angie’s List. Because of this I’m certain I was on the defensive and asked a million questions. He was very patient and took plenty of time answering all my questions. He was very knowledgeable and helped educate me on my options and the advantages/shortfalls of each. When I came to the actual bid, I felt it was very competitive compared to other bids I’d received. I felt so well informed and confident at that point I cancelled two other appointments I’d made for that day and signed up with Gorman Mechanical. He was able to promptly arrange a great deal on financing the bulk of the cost, leaving me to pay out of pocket for a couple last minute additions (extended warranty/Reme Halo). They did not want this until installation was complete. A couple days later they installed my new system and I’ve been very happy with it. Shortly after installation I had several other questions about maintenance and a small amount that was overcharged upon installation. He was very responsive answering my questions and arranging for a prompt refund check to be sent. Fortunately, it isn’t often that I need to spend so much money on an important purchase like this, but I felt very confident with my decision and going through the process with him and Gorman Mechanical made it painless. I wouldn’t hesitate to recommend Gorman Mechanical to friends and family.

The repairman, Tim H., was prompt and courteous. I explained that he was a second opinion for our 21-year-old AC. The first company said that I would need 2 parts totaling $600 plus a coil that they would have to send a salesman out to quote me a price. Also first company was suggesting that I really needed whole new system. After inspection, Tim showed me how a part was wired the wrong way and he replaced a compactor and repaired a burnt wire. 2 lbs Freon were added. Total cost was retail: $217.75. I had a warranty so I paid less but what a difference in $600.00+ and $217.75! AC is working fine now. And we didn’t have to buy a new system. Thanks, Gorman Mechanical and Tim H.! The world needs more honest repairmen like you!
