HVAC General Maintenance Tips
Here’s a handy list of HVAC general maintenance tips to keep your system running smoothly and efficiently all year long:
Frequency: Every 1-3 months, depending on usage and filter type.
Why: Dirty filters restrict airflow, making your system work harder — leading to higher energy bills and potential damage.
Check: Ensure vents are open and unblocked by furniture or curtains.
Clean: Use a vacuum to remove dust and debris from registers for better airflow.
Upgrade: Consider a programmable or smart thermostat for better control and energy savings.
Test: Make sure the thermostat is reading the temperature accurately.
Why: Clogs can cause water leaks and humidity issues.
How: Flush the line with a mixture of vinegar and water every few months.
Remove Debris: Keep leaves, dirt, and branches away from the unit.
Clean Coils: Gently hose down the coils to improve heat exchange efficiency.
Signs: Higher energy bills, uneven temperatures, or visible dust buildup.
Solution: Seal small leaks with duct tape or mastic sealant. For larger issues, call a professional.
Why: Low refrigerant can reduce cooling efficiency and damage the compressor.
Pro Tip: Only a licensed HVAC technician should handle refrigerant checks and recharges.
Components: Motors, fans, and bearings may need periodic lubrication to reduce friction and wear.
Check: Your owner’s manual for guidance on lubrication points.
Spring: Test cooling mode before summer hits.
Fall: Test heating mode before winter.
Listen: Unusual noises like banging, hissing, or grinding may signal a problem.
Frequency: Ideally twice a year — once for cooling (spring) and once for heating (fall).
Why: A pro can inspect electrical connections, test system performance, and spot early signs of trouble.
Our old water tank was installed in 1997. Wasn't working as well as it should so we looked into a tankless as it is more efficient and a space saver! we had used Twintech in the past for a furnace cleaning and were satisfied with that so we decided to ask for a quote for the changeover. Gary arrived and provided the options and the quote fit within our budget so we decide to go with them after receiving a few alternative quotes from other companies. They did what the said would be done and it was completed within a reasonable time frame! Removal and cleanup of the old tank was seamless. We are now enjoying consistent and efficient Hot water! I recommend Twintech and would use them for future projects!
One of the most honest HVAC companies out there! Dave was very helpful and informative in helping us choose a new AC unit. While they werent the lowest quote, we went with them because we trusted Dave and he was the most honest guy out of the companies that quoted us.
Greg and his crew who installed the unit were very professional and did a great job. If I could do it over again I would choose Twintech again.
Relocated and replaced our air conditioning unit. Fast, professional, and high quality service. We would definitely use them again for future projects!
The term excellent or incredible does not seem high enough praise for the Twintech Heating and cooling company that recently replaced our 15 year old furnace. To start with, the response from Dave at Twintech to our original pricing request was the quickest and most professional of the 5 prices we received which included two of the primary natural gas providers. The Twintech pricing was the most competitive by a considerable margin.
We had Dave visit our home to confirm all pricing which he did and scheduled us for next day installation which was not offered my the majority of the other providers.
The installation; the team arrived on time and provided coverings to all of the hardwood flooring and stairs and proceeded with the removal and reinstallation of the new furnace, the workers predicated six hours and were completed in five hours. I have to mention how courteous and polite the workers were each time we interacted with them from start to finish.
The final result was amazing, all materials were cleaned up and removed from the house and the workmanship very impressive.
One feature that really stood out for me which shows a high level of professionalism was that we had various condensation hoses from the furnace , humidifier and an air filtration unit meeting at the one drain, the installation crew ran PVC tubing including elbows along two sides of the furnace to guide the hoses into one PVC tube at the drain, it looks great!
When the install was completed and tested the Twintech technician guided us through the features and recommendation's for care of the new furnace.
We highly recommend Twintech to anyone for the outstanding service provided to us.
I didn't hesitate to call Twintech in for a 2nd time as they did an outstanding job installing my new furnace last year. This time my 18 year old air conditioner was on its last legs. Greg and the team are top notch, highly skilled technicians. The job was executed in a timely and professional manner. Greg was extremely thorough and went the extra mile to make sure everything was operating efficiently. Lastly, Dave is a true gentleman and really made the customer experience pleasurable and worry free. Always remember that good work ain't cheap and cheap work ain't good.
It's so hard to find solid companies these days, but I was very pleased to find one in Twintech. Greg and his crew were very clean, respectful and professional. We were most impressed at how all the things they said they would do, were done. Sounds strange, but usually when a contractor comes to your home they say they will take care of this and that, make sure this is done, etc but when the work starts you have to constantly remind them of your previous discussions. Greg ensured every item he said he would do was done, no reminders required. The work was done right, at a fair price and on time. We will be sure to call them when our A/C unit dies (fingers crossed that's not going to happen too soon :) )
Replaced our aging hot water tank with a tankless system. Excellent work, fast efficient and clean.
Walked us through the new system and recommended maintenance schedule.
This is our second time working with TwinTech and we are very happy with the quality of their work and professionalism.
Efficient work and great follow up by the team at Twin Tech. Great product and communication.
On coldest night of the year our furnace quit. At 8:40 in the morning Greg arrived and gave us a diagnosis and a recommendation. By 2:30 we had a new furnace and were warm again. Great company. Great customer service. Good reasonable price.

Twin tech team was very efficient and prompt. They provided a quote within hours of request and got the job done on time. No disruption to home function. We would highly recommend this team. Job well done.

We were new homeowners in need of a second opinion. TwinTech Heating & Cooling were Amazing and professional. Very knowledgeable and great service all around. Recommend to anyone looking for honest and reliable services. Treated with respect and care. Thank you Greg, Mitch and Bob!
TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all! I did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!
Amazing experience with TwinTech Heating & Cooling! Their team was professional, knowledgeable, and efficient from start to finish. They installed my new furnace quickly and left everything spotless. The technicians took the time to explain everything and made sure I was comfortable with the system before they left. Great customer service and fair pricing. I highly recommend them for anyone needing HVAC services!
Great experience all around. Bob was sharp and easy to talk to, and Greg handled the installation perfectly. Would hire them again in a heartbeat.
