Common HVAC Problems

Your heating and cooling system works hard year-round. But when something goes wrong, it can disrupt your comfort and efficiency.

Here are some of the most common HVAC issues we handle:

HVAC SYSTEM NOT TURNING ON

If your HVAC system refuses to start, it could be caused by thermostat malfunctions, electrical issues, or a faulty control board. Our experts will diagnose the problem quickly and get your system back up and running.

LEAKING WATER OR REFRIGERANT

Puddles or refrigerant leaks around your indoor or outdoor unit are signs of trouble. Left unaddressed, these can cause serious system damage. We’ll locate the source of the leak, make repairs, and ensure your system runs efficiently again.

WEAK OR UNEVEN AIRFLOW

Hot and cold spots in your home often point to poor airflow. This can result from blocked ducts, dirty filters, or a failing blower motor. We’ll inspect your system and restore balanced, consistent comfort throughout your space.

BLOWING INCORRECT AIR TEMPERATURE

If your HVAC system is blowing cold air in heating mode or warm air in cooling mode, it could indicate thermostat calibration issues, refrigerant problems, or compressor failure. We’ll find the cause and restore the right temperature quickly.

SYSTEM FREEZING OR OVERHEATING

When your HVAC system freezes up or overheats, it may be due to airflow restrictions, dirty coils, or mechanical wear. Our technicians will resolve the root issue and help prevent future breakdowns.

Frequently Asked Questions About HVAC Repair & Installation

Q1: What’s the difference between residential and commercial HVAC systems?

A typical residential HVAC installation takes one day, but larger or custom systems may require up to two. Our technicians work efficiently to minimize downtime.

Q2: What’s the average lifespan of an HVAC system?

With regular maintenance, most HVAC systems last 10–15 years. Proper care, filter replacement, and annual inspections can extend their lifespan even further.

Q3: Should I repair or replace my HVAC system?

If your system is older than 12 years, has rising energy bills, or needs frequent repairs, replacement may be more cost-effective. We’ll help you decide based on your system’s condition and budget.

Q4: Do you offer financing for new HVAC installations?

Yes. Day to Day HVAC partners with trusted lenders to offer flexible financing options, making it easy to upgrade your HVAC system without breaking the bank.

I had a wonderful experience with Day to Day! They were able to squeeze me in same day for a smart thermostat install and their pricing is very fair. They are now my go to HVAC company 🙂

David was professional and responsive. We went back and forth trying to identify the best heat pump for my needs. Once i found one, installation was scheduled for the next week. Installation went fine and took less time than originally anticipated. We had an issue with a clogged drain pipe and David came right out and fixed the issue. I highly recommend Day to Day Heating and Cooling.

One of my properties wasn't blowing out cool air. It was still a new build, yet we weren't getting service from the builder on time. David came quickly and got our air conditioning up and running in less than an hour, and provided us with plenty of tips on preventative care to help avoid future problems. He fully explained to me where my AC units' stats are and what they should have been. I would recommend him to anyone within the San Diego area and surrounding counties. Five-star service and very professional.

Day to Day is the best! My low voltage fuse kept blowing, and David ended up finding an electrical short in the contactor. He replaced it, and everything is working perfect. Highly communicative, friendly, and could not recommend more!

 Verified My AC needed maintenance and ... it had stopped cooling. 
I called Day to Day and they were able to schedule within a reasonable timeframe and the cost is pretty good. 
They also installed a smart thermostat. 
My AC needed a little fix, he was very honest telling us what was wrong and how to check for this issue.
I will call them now for vent cleaning next.
Totally recommend !

 Verified From initial yelp consultation to the time for service, David from Day to Day Heating and Cooling was courteous, professional, and diligent in the services performed. I reached out for a basic ac cooling service and touch up and David was able to get our system up and running like new, as well as take care of some other issues that came up on the spot. David was able to improvise and solve the issues, all with a reasonable price. We will definitely contact this company for our future ac needs. Thank you David and Day to Day Heating and Cooling!

 Verified I can't say enough positive things about David. He is incredibly prompt, friendly, knowledgeable, and communicative. He identified the problem quickly, and made himself available to fix my AC the moment the broken part was available. His prices are fair. Very, very highly recommended.

 Verified David was super quick and responsive!  He came out for the repair the next morning, was on time and came ready for the job. Very knowledgeable and immediately diagnosed the issue, showed me the issue and provided options for repair (our in-wall heater wasn't working). Price for replacement and labor was fair and made easy for both parties. Definitely recommend and will be contacting him again for future issues!

 Verified David was professional, easy to communicate with, very transparent and reasonably priced. I had gotten other quotes from larger companies for some seemingly simple maintenance and felt like each technician was working for a commission to upsell me, not to give me what I actually needed and make a happy customer! Next time I have any maintenance needs or repairs, Day to Day will be my first call!

 Verified I highly recommend Day to Day. We needed sediment traps installed on a couple of furnaces to meet home inspection recommendations. As we are in escrow, we needed the project done on very short notice. David from Day to Day was the first vendor of many to respond. After fielding several vendor quotes, we felt most comfortable with David's estimates and timeline. He walked me through a couple of options, got out to our property the next day, was very friendly, professional and completed the project in a reasonable time. He was thorough in explaining the details of the project and even took photos and videos for our realtor. I have nothing but positive things to say about David and his company. My family and I are very pleased with the outcome. Highly recommended!

 Verified FIVE STARS!!
David was very knowledgeable and helpful right from the start. He was very accommodating and was open to exploring different ideas and cost effective ways to fulfill the project. I confidently recommend Day to Day to anyone in need of AC solutions!!!

 Verified We accidentally bought a fixer upper. When the old HVAC system flooded our attic, we were at our wits end. Shaun and the guys at Day to Day were recommended to us by our water remediation folks. They came out, diagnosed the problems, and then worked with us to install an entirely new HVAC system through the whole house. I do mean *entirely new* - ductwork, moved and added registers, whole new compressor, new furnace. They worked quickly and professionally and took amazing care of our home every step of the way. Our insulation guy came back after they finished, and went out of his way to compliment how nicely the ductwork had been done in the attic.

 Verified My thermostat wasn't working properly so I called Day to Day.  They were responsive and made the appointment that same day. I highly recommend them. David took the time to explain what was happening.  I'm a happy customer.

 Verified Professional, thorough and honest. Shaun and his team does great work. We were very impressed with his help. Our HVAC system is very old and had many issues. Shaun and his team gave us honest advice so we were able to make the best decisions for our home. I would highly recommend this team to anyone and will only use them in the future.
