"Lockhart Electric has done several projects for me. Everything from replacing switches and fixtures to upgrading my breaker panel. They are always so helpful and knowledgeable. The prices are always fair, and they always give me options to help me make the best decisions depending on my need and my budget. I trust them with my home and I wouldn't call anyone else."

"When my HVAC unit went out I called A n 1 at 12:30am, as I have gotten home from work not too long ago. He answer and said he be right there. He came through check it all out and let us know exactly what needed to be done. He quote us too on the price if we decide to stick with him. Since he is a smaller personally owned company he didn't have financial options. So we had to think if over. Anyways I offer to give him some cash for coming out here so late and he kindly refuse, which was very kind of him. Even though it was already 2am by the time he was done checking it all out. After a few calls to other companies we realize we rather pay a hard working, honest man and help smaller local business. Also his price was unbeatable and the quote he quoted us was what we pay no hidden cost or anything. Needless to say we were highly satisfy with his work and his honesty. He was upfront with what was needed and didn't not try to sell us on anything else. Highly recommend his service! And the price was very reasonable!!!"

"With all the super hot days recently, our air conditioner wasn't able to keep up. Day 1 was able to get an almost immediate appointment and had us back up and running in no time. Very professional crew, and kept all pricing and repairs transparent. Would definitely use their services again."

Heating and Air Conditioning questions, answered by experts

Don’t run your AC with a wet filter. It can cause your AC to work too hard, which will run up your utility bill and cause extra wear and tear on the system. You could also spread moisture and mold throughout your house. Turn off the AC, remove the wet filter, and check for cracks or clogs. Fix the problem (with a pro’s help, if you need it), and put a dry filter in place before you turn the system back on.

Deciding whether to replace just the AC coil or the entire system depends on the age of your unit and the overall cost. Replacing a coil is less expensive than a full system replacement, but it can still be a pricey repair. If your HVAC system is relatively new and still under warranty, or if the replacement cost is significantly lower than a new system, replacing the coil can be a worthwhile investment that restores efficiency and extends the unit's life. However, for older systems (nearing the end of their 10-15 year lifespan) or those with extensive damage, it is often more cost-effective to replace the entire AC unit. Mismatched coils in an older system can lead to inefficiency and future breakdowns, so a full replacement ensures optimal performance and avoids further costly repairs.

The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.

Yes. It's normal for the AC compressor to cycle on and off intermittently in dry mode as it maintains the desired humidity level. The compressor cycles to prevent over-dehumidification and to maintain a comfortable indoor environment. This cycling behavior ensures efficient operation and optimal humidity control, contributing to the overall effectiveness of the dry mode function in your AC system.

Your heating and cooling systems cost you the most on your electric bill and make up 50% of your bill on average. Your washing machine, dryer, oven, and stove contribute significantly to your electric bill as well. Lights, fans, and smaller electronics add up, but aren’t the biggest energy consumers. You can reduce your power usage by setting optimal temperatures on your thermostat and investing in energy-efficient appliances.
